You got me curious what the highest value ever seen might be...I can't find any solid answers, but this post by a meteorologist claims to have seen values "over 80" before in the Midwest. This paper (PDF warning) looked at 560+ giant hail events between 1995 and 2009 and only 26 of those got to 75 dBz or above. Whatever happened in that storm, it was very significant I'm sure!

I'd highly recommend https://www.wunderground.com/ if you're just looking for a simple, relatively clean site to get your basic weather forecasts, though there are also a number of options for radar, satellite, etc. if you want that.

There's also https://darksky.net/, which is fairly clean and simple but also provides nice maps, very basic radar, etc.

From your question I assume you aren't looking for anything too complicated, like numerical models and advanced radar/satellite and whatnot, so I think those ought to do the job you want without too much fuss.

And www.weather.gov is also a nice resource; just click on your general area on the map and you'll be brought to your local WFO (NWS Forecast Office) where you'll find a bunch of links to detailed forecast discussions, 7-day forecasts, basic radar, etc.

its been this way for 3+ weeks in colorado... practically the entire country was bathed in warm... going to drop away for a bit here in a few days though.. will be closer to average temps for most of the country

I work with meteorologists and atmospheric scientists and they disagree on a lot of topics. But two things remain constant: Accuweather sucks and don't trust any forecast more than 7 days. Some even say less. 3-day forecasts are very accurate guesses that are backed up by lots of math and science and anything after that, it just gets more vague. Check out historical weather data in the area you plan to be.

Also check out https://www.wunderground.com/cat6/Category-3-Michael-Intensifying-En-Route-Florida-Panhandle

The damn blog is going so fast now it is hard to keep up. The Dvorak T numbers were at 7.4 a little bit ago, which is insane. If it keeps intensifying it will be the strongest storm to hit the panhandle.

Keep in mind that this type of map projection will make objects farther to the north/south appear larger than they really are. So it isn't really as big compared to Harvey as this map makes it look.

Here's a cool site that helps you compare actual sizes of things: thetruesize.com

I'm a bit biased but I prefer this one: https://play.google.com/store/apps/details?id=joshuatee.wx ... radar but lots of other stuff as well, my goal was to replace all the weather apps on my phone with just one. The radar has some features the other's don't have but also lacks some of their features, etc.

Well speaking of hurricanes causing winter conditions. There was one rare weather event that happened on December 2004 where an extratropical storm in the Gulf of Mexico dropped snow all over from South Texas to Louisiana.

I lived in South Texas where it rarely snows and that winter storm in 2004 was my first time seeing snow. Then I got to see it again in blizzard form during December 2017 during Winter Storm Benji where it did drop snow in Florida.

Officially a category 4 again, possibly going to reach category 5.

To everyone in Florida, please get out while you can or be as safe as possible if you plan on riding this thing out.

The CO low’s central pressure has fallen to 988 hPa at 1500 UTC. Since its pressure has dropped from 1005 hPa at 1800 UTC yesterday, and the bomb equation calculates 17 hPa fall in 24 hours as satisfying criteria at 38N, the CO low has met bomb criteria with 3 hours to spare.

https://www.wunderground.com/blog/JeffMasters/second-warmest-us-february-on-record-chalk-it-up-to-greenhouse-gase

One region being colder than average doesnt mean the trend across the nation can be ignored..

https://www.nytimes.com/interactive/2017/03/08/climate/early-spring.html?_r=0

No this was legit, it would have been a category 5 storm under the Saffir-Simpson.

https://www.wunderground.com/hurricane/western-pacific/2016/Super-Typhoon-Meranti?map=history

Jeff Masters has a very good post on this event.

A longish Tl;dr:

1) While there were 42 tornadoes, the tornado outbreak was generated by just two supercells. (I'll add: A supercell developing a tornado, then having the tornado lift, then having it touch the ground again is not uncommon, but this is rather remarkable.)

2) A boundary between humid unstable air and cloudier more stable conditions appeared to serve as the focal point of storms. (I'll add: I think he's implying this served as a source of low level vorticity?)

3) The humid airmass allowed for the base of the supercells to develop very close to the ground. This is a not so well known ingredient that aids in tornadogenesis.

4) Wind shear was not forecasted to be high, but a couple of soundings indicated sufficient wind shear in the area.

>From what I gather, the south easy is extremely active in the spring where as the Midwest doesn't really kick up till may?

Yup, that pretty much sums it up. Over the next few weeks, the risk ramps up dramatically.

If you have an Android phone, the app below is everything you'd want from an official NWS app. It uses all NWS data. There is also a pro version for $2 that is well worth it to get rid of the ads. Not a sponsor, just a user that loves it.

https://play.google.com/store/apps/details?id=com.nstudio.weatherhere.free&hl=en_US

Just reinstalled the latest version from APKMirror and it still doesn't have radar layers. Just weather stations and a few other half-working features. No change. The Weather Channel is still trying to get you to use their new version of Storm which sucks.

Weather Channel stopped being about weather like 15 years ago. Now it’s a reality TV network with an occasional live variety show that might or might not mention current weather.

Their site’s a forgotten relic of a bygone era.

These days I use wunderground’s 10 day forecast chart to understand my local forecast. Here it is on their site for SF:

https://www.wunderground.com/forecast/us/ca/san-francisco/37.78,-122.42

Their app is just as good.

Decent radar too, though I use the simply named “Lightning” app or the lightningmaps.org website to track lightning strikes.

What is the point of your post? It might have been 30c right along the beach (it was 30.5 at the airport, but it is <em>currently</em> 32C in downtown Nice (8pm local time). The high was 39C.

Found an interesting article about why tornadoes get missed. Surprisingly, lead time has gone down in recent years.

Anyway, the 1984 F5 tornado in Barneveld, WI struck at 1am with no warning. The only warning people got was a loud clap of thunder as power was knocked out shortly before the tornado hit, which woke up many residents.

Do you want a meteogram with wind barbs? You can do something like this with nearly any graphics plotting software if you're clever.

For instance, you can do this very easily in Python with the matplotlib library. Just take your winds and decompose them into u and v components, scaling for the windspeed (should be easy to do if you know wind direction and speed) so that you have two 1D arrays. Then, just call this matplotlib routine and you're all set.

e.g. -

import numpy as np from pylab import *

u = np.random.random_integers(-20, 20, 10) v = np.random.random_integers(-20, 20, 10)

figure() barbs(u, v)

You might like my app which is free and no ads: https://play.google.com/store/apps/details?id=joshuatee.wx&amp;hl=en

It has what you are looking for although it also has a whole lot more ... thx, Josh

The Weather Underground app will allow you to do just that. I also recommend changing to NWS forecast in the settings menu.

Check out IFTTT. It basically connects to services (including weather sites) and you can set it to trigger an action when a certain condition is met.

For instance there are triggers for Weather Underground when the current temp (or forecasted high/low) gets to a certain value. You can then have it send email, texts, tweets or do other actions. Not completely sure about Windows 10 notifications though.

Let me know if you have questions setting it up and I can help.

Depending on the strength of the storm it typically varies from 1,000ft to 10,000 ft above the surface. It's fascinating stuff. You can follow along with there missions here.

Also here's an amazing story of a flight that almost went down in Hurricane Hugo by Dr. Jeff Masters.

https://www.wunderground.com/resources/education/hugo1.asp

These guys offer such valuable information that not only let forecasters know the exact intensity of a storm, but also gives us data that can plugged into our weather models that allow us to deliver more accurate forecasts!

ROFLMAO.. you know and understand less about climate science than my 8 year old nephew.

Hurricane Sandy was the second most costly hurricane after Katrina '05.. happened in '12 if i am not off my rocker

oh and Ike was in '08 and was the third most expensive storm in our US history..

wilma was in 05 and is 4th..

andrew in 92 still hanging on at 5th

ivan in 04 is 6th...

Fucking Hurricane Matthew was last YEAR, cat 4/5 storm that crushed haiti (Sorry its not your precious usa)

You have a terrible memory or are just profoundly uninformed.

https://en.wikipedia.org/wiki/List_of_costliest_Atlantic_hurricanes

we got lucky for a few years that we had no major landfalls in the US.. that doesnt mean the cat 3- 5 storms werent out in the ocean churning away and missing land by a happenstance of the jetstream.

To answer your first question, https://www.windy.com/ is a fantastic and immaculate site I've been using for as long as I can remember. I've never been bothered to look through everything in-depth but I'm sure there will be a few features that would pique your interest.

Good eye, I didnt notice that. This morning it was the only post on his site with that cloud structure (there are now two). Maybe I misinterpreted the original post and it's not posted on his site because I dont see a match, but there are two similarly cool photos: https://vsco.co/jkt13/images/1

This is the facebook post by Justin Berk that led me to the pic: https://m.facebook.com/story.php?story_fbid=10157114223488476&amp;id=54875673475

I live in Santa Cruz CA never goes below 35. Not sure how many days above 75 we get but far less then San Diego or Hawaii that's for sure. We still have 80 degree days in the summer however so you have to go a bit further north to keep it under 75. Most people actually like it up to 85 or so which is why everyone loves San Diego and Hawaii.

According to Weather spark Fort Bragg, California is a close match to the range your looking for. "Over the course of the year, the temperature typically varies from 42°F to 72°F and is rarely below 34°F or above 77°F."

Silver citys southern latitude affords it mild winters, while its relatively high altitude of 5800 feet gives it mild summers.

A really cool website for you to use to explore questions like this is weather spark. It graphically displays seasonal weather by city.

Nope. IBM owns the Wunderground Digital Assets. Weather.com or NBC sold off that part of the business to them. One is no longer the other. Death of a good product.

I checked my weather app this morning and zoomed out, when I saw this weird pattern on the rain radar... There were no clouds in the area, so I don't think it's actually weather related.

The pattern was pulsating over a few hours, as you can see, if you open the link

Does anyone know what that is?

Sorry, if this is not the right sub.

It's not, The forecast calls for a near-average season below 2016's season.

I've been watching Arlene since it was a Low pressure system on Sunday, it's a bunch of coincidences that keep this storm alive. It was supposed to have disintegrated by now. It should get absorbed by an extratropical low south of it.

This storm is a freak occurrence, and is not a bellweather for the season. If it stays alive through the weekend, however, the hurricane center may want to start coastal evacuations. Huge potential, low likelihood of it surviving the absorption.

There is no official NOAA app. He was probably referring to this app - https://play.google.com/store/apps/details?id=com.nstudio.weatherhere.free

There's a pro version, totally worth it. Not sure if pro is required for notifications, I had pro before they added that feature.

This weather app literally takes the forecasts/information straight from the National Weather Service and makes it nice to see on your phone. You can look all this information up on weather.gov.

We used the Kestrel in the Air Force. It was accurate enough for us to use to take official observations with, so it will likely do well for you.

For indoors at home, Amazon has a pretty well received dedicated humidity sensor.

For mobile there's an app called Weather Archive on Google Play or iTunes. It has historical data and forecast. Comparison feature, radar, etc are missing though. He pulls historical data from www.ncdc.noaa.gov/ and forecasts from wunderground. Definitely not as nice as Weatherspark though..

If you have Android this is free ( disclaimer: i wrote this) and does include SRM along with usual Level 3 products and some Level 2: https://play.google.com/store/apps/details?id=joshuatee.wx&amp;hl=en

A few folks have told me it's a good learning tool as well. Hope it helps if you have Android. --Josh

For those on Android this is available w/o cost ( w/o ads ) and is opensource: https://play.google.com/store/apps/details?id=joshuatee.wx&amp;hl=en

It displays Level 2 base reflectivity and base velocity and quite a few Level 3 products. ( disclaimer: i wrote this )

I'm curious what problems you've had with WeatherBug. I've found it's still the weather app I prefer the most for these reasons:

• noaa weather alerts as push notifications, and I can customize the audio
• forecast and current weather are about as reliable as anything else for the mid term
• uses local weather station data, which for me has been reliable

Beyond that, I keep RadarScope handy on my phone and tablet because it's awesome.

Also been trying out InstaWeather for Wear - it's purdy.

I'm always looking for better solutions (I love wunderground, but not their android app). Killer thing for me seems to be the push weather alerts and the custom sound for it.

I know the site is bad, especially on mobile, but this article is a pretty good explanation. It’s a common error for radar sites around sunset and sunrise. It has a lot of causes, but temperature inversions, either pockets of cold trapped under warm, or vice versa are typical around those times. Sometime if you watch during sunset, you can watch it spread west across the radar sites.

For other examples, this page mentions that event but also the town of Alamosa, Colorado, which once set its daily record highs and lows within the same day three days in a row.

Where are you seeing this? I see 20s for Vancouver on both sites I'm looking at. Are you sure you're not looking at historical lows?

https://www.wunderground.com/hourly/ca/vancouver/date/2020-1-14

The Weather Channel. I have been using The Weather Channel for a really long time and it seems to be often accurate. It has many details for the weather and they actually give you weather info you need. You can check the radar and future radar, as well as where lightning has recently struck. It has many other features as well. Just go mess around with it, and you will probably find some really helpful stuff. Just type in weather.com and you should be able to go there.

As somebody else said above, the radar only extends a little bit out. Take a look at the satellite shot and you will have a much better understanding. https://www.wunderground.com/maps/satellite/regional-infrared

>green sky tornadoes

Thanks I took your advice and found a little more info! This article is from accuweather (sorry).

>“When this setting light is transmitted by a massively thick cloud composed of water droplets and ice particles, the results are a green sky,” said Bohren.
>
>The professor compared the phenomenon to putting a glass of water with a drop of yellow food coloring behind a glass of water with blue food coloring to produce the same tint of green that the light in the sky transmits.
>
>Such large thunderstorm clouds have the potential to produce severe weather such as tornadoes, large hail, frequent lighting and flash flooding, but do not guarantee any of these potential outcomes.

Well, on the upside weather.com has a lot of data stylishly displayed. On the downside the website has serious loading issues on occasion and same with the map on the mobile app. As a webdev it is very annoying to see a website that is ran by IBM be so far behind other high traffic websites like ESPN and reddit. They need a redesign of the backend

I agree that the 1.75" measurement is suspect. But it seems to be possible to get more than 8" of rain per hour. Take a look at these other records:

https://www.wunderground.com/blog/weatherhistorian/what-is-the-most-rain-to-ever-fall-in-one-minute-or-one-hour.html

The current record holder is 1.22” in a minute in Maryland. Link. I think it’s possible.

My best guess is that you captured a phenomenon known as radar attenuation - when a pocket of very heavy rain was directly over the radar site, some of the electromagnetic energy of the radar pulse was prevented from making it back to the receiver, causing the resultant reflectivity returns to appear lighter in the surrounding areas, then when the heavy rain moved on in the next scan, the full signal strength of the returns resumed, resulting in a heavier rain look on the screen in what appears to be a short period of time.

You can read about the problems it causes on this page (scroll down to "TDWR attenuation problems").

omg thanks! adblack was starting to fail misrably. soo many ads starting to not be blocked even with forcefull updating the listings. ever since the sellout to google. garbage. thanks! this map is still useless AF though... https://weather.com/weather/radar/interactive/l/39.28,-84.45

There are a few good apps if you like. I use a few as each seems better for different things. For rain/snow forecasting with radar imagery I use the MyRadar app for iPhone. For wind velocities and directions projected onto a nice map system, I use the Windy.com app that I found here. Both have been really good for helping to know, with a visual reference, where and when weather is going to be a challenge.

I love the strong storms of this time of year in the Seattle area! (I live on a bot in lake Union.) and like to know when I have to make sure we are all tied down snug and secure. These apps help.

This happened sometime last week, too. On this map it indicates there are several weapons ranges in the vicinity. I am unsure if that is just coincidence or if there is another reason.

Alabama did try to mandate that tornado shelters be incorporated into trailer parks after a tornado hit one and killed 11 people in December 2000. They tried again last year, but nobody (including trailer park residents) wants to pay for it.

Accuweather is not very accurate, is it? Ha.

Try Weather Underground (wunderground.com): https://www.wunderground.com/history/airport/NZCM/2016/10/17/MonthlyHistory.html?req_city=McMurdo&amp;req_statename=Antarctica&amp;reqdb.zip=00000&amp;reqdb.magic=1&amp;reqdb.wmo=89664

-Why did you decide to get a personal weather station? My hometown was about 30 miles from the closest reliable station (Which was an ASOS) so the actual conditions could vary wildly, so I decided to install one that people could use. The town is very small.

-What do you do with it? Provide weather data? I mean, I archive all the data at one minute intervals and it produces graphs and stuff, so it's a useful history tool.

-Where do you publish your data? (personal website, Weather Underground, CWOP, etc) I have a website that the data uploads to that I display it in an easy to read fashion with all the useful data people want, it also has the graphs and an almanac feature that you can pull past data from. Also an interactive map/hourly forecast graph. Also has the output from my home-ran WRF model, but no one looks at that except me lol. It also uploads to CWOP and Wunderground.

-Does anyone outside your household get any use out of the weather station? It's a community weather station, so yes a lot of people use it. I check it a few times a day mostly to make sure it's still working but I get people all the time telling me how much they appreciate it.

-Where do you have it sited? (pictures welcome!) It's sited approximately 300 FT away from the nearest building, which is the science center that hosts it. It's on the top of a hill and no trees nearby for optimum performance.

Wunderground actually did a feature about me in their featured PWS blog, so I have more information there: https://www.wunderground.com/blog/PWSmet/comment.html?entrynum=31

I love weather stations though and love helping people out with them. I only have one, but i've experimented with a lot of different ingest solutions and such and am always willing to help out.

https://www.windy.com/-Snow-depth-snowcover?snowcover,30.335,43.462,5

Here you can see that only a small part near the southern border of Jordan that has some snow, and that is normal for that area to get snow sometimes.

Cold air damming is the common label for what is happening. Look at https://www.windy.com/-Temperature-temp?temp,34.710,-82.370,7,i:pressure and you can see the warmer air moving northward and being stopped by the cold air dam.

You can even see the shape in the lower one.

It's neat, but I don't know what the cause is. Is it some side-effect of the turbulence, or is the radar actually using such a low elevation angle that it's capturing the blades? Most of the time it goes undetected, but once in a while they even show up on the standard composite radar image that wunderground.com displays.

That's what I'm seeing as there is a lot of uncertainty right now on the models. I go past the five days, it has this storm forming into a Depression slamming into East Texas/Louisiana coastline.

What is keeping it down in Campeche is a low pressure trough sitting in the middle of the south coastline in the Gulf of Mexico.

Oh! I was living In Memphis during Hurricane Elvis and it was terrifying. So much destruction of the shallow root oaks.

Thank you for your reply!

AccuWeather sucks almost as much as the Weather Channel. I found an Android app that I like a lot. It just pulls in the NWS info, has hourly readings and a radar, too. Paid version allows storing unlimited locations.

Not sure if it's in the Apple store.

https://play.google.com/store/apps/details?id=com.nstudio.weatherhere

Eweather HD and Dark Sky can show UV forecast. EWeather can set up a nice hourly widget and can also do warnings.

Most modern smartphones have a barometer in them. It will be sensitive to its altitude changes but should still produce very high-quality graphs. There are millions of barometer apps on both the iOS and the Android app stores. Some of them will show you a graph.

I make a weather app on Android that shows a graph of your recent barometric pressure from your device over the last 3-4 days. It is meant for weather forecasting research, not active forecasting given the data source is noisy, but it might be useful for you?

I make All Clear Weather towards this goal. It's not (yet) a full replacement for what you are missing but it might help! But do note, it's not meant for headache forecasting, not yet at least! Maybe you can derive some value regardless.

After messing around with a few, Weather Timeline seems pretty good and I think I'll stick with it for the foreseeable future. Very customizable. Now if only people could integrate Radar Scope in to their forecast apps...

https://play.google.com/store/apps/details?id=com.samruston.weather

Radarscope is $10 but you get what you pay for.

I can't say enough about NOAA unofficial. It's free with a small ad banner, $1 to get rid of the ads. It takes data directly from NOAA and puts it into a user friendly interface. Everything I'd ever want in a weather app.

I personally use radarscope and this app Link: https://play.google.com/store/apps/details?id=joshuatee.wx It's Android only so if you have an iPhone you're out of luck. But it's awesome, it has literally all the information you could ever need but there's a bit of a learning curve to find where everything is at. It has level 2 radar so the same as radarscope however it's uncompressed so it can go through your data pretty quick if you're using it on the road.

Yeah! It's called Storm Alert. You have to pay a subscription fee for the lightning feature, but it's only $3 a year, well worth it in my opinion.

There's also a free website www.lightningmaps.org. They even show expanding circles representing the thunder, and it's right on point for when the line hits your location and you hear the thunder! I think that might be where that app gets the data for the lightning, but I could be wrong.

Provided you are on Android ( not sure for iOS ) what is generally referred to as "Emergency Alerts" or "Emergency Broadcasts" can be configured to alert on Tornado warnings and to play sound continuously until acknowledged.

Additionally, I like your idea and I just added it to my weather app: https://play.google.com/store/apps/details?id=joshuatee.wx&amp;hl=en

I probably won't update google play until next month but if you are interested I can email you my dev version and you can sideload. --Josh

If you are meteorologically-inclined, try out WX. The UI is kinda hard to navigate at first, but it has a pretty decent radar you can use along with upper air, satellite, SPC and text products.

For mobile there's an app called Weather Archive on Google Play or iTunes. It has historical data and forecast. Comparison feature is missing though. Definitely not as nice as Weatherspark..

Here is another example from this year ( SW of Dallas March 8th of this year I think ) that I use as an example for my app - the image the has velocity on top , ref on bottom. 2nd URL directly to the image but not sure it will work well. These were so well defined that even with Level 3 it was apparent.

https://play.google.com/store/apps/details?id=joshuatee.wx https://lh3.googleusercontent.com/WwpXQBf00L7sAfb-kV9r4NJaVD4Lrqi28WSRrfecJYVGZEgFVyn2yCkwY3BPyOew_vNo=h900

My feedback is a bit biased but you might like "wX" : https://play.google.com/store/apps/details?id=joshuatee.wx

... has direct access to quite a few model and mesoanalysis tools ( and other things ). no ads, free, and open source also .

If you happen to have an Android phone with a barometer (any recent Android phone likely does), install PressureNET. This app crowdsources pressure measurements, something that has been shown in research to improve weather forecasts.

It sounds like you're looking for something to program, but can't think of a good programming-related task, unfortunately. Most of the research-based programming that's done in meteorology is done as part of an individual's research or a larger collaborative project, both of which don't lend themselves to outside assistance very easily.

This is rooted in the fact that FOSS is not a term often seen in the field, though there has been some attempt to change that. A lot of the big research models (at least in the US) are now open source (though they're way too big for one person to just start digging into), and there is a push to do more work in freely available languages like Python instead of languages like FORTRAN and MATLAB. Git and other collaborative tools have barely made an appearance for most people.

Hopefully, someone else here has an idea though; the field could always use more code contributed by people who actually enjoy coding! A lot of code is developed by scientists that have little interest in coding and view it as a necessary obstacle to getting science done.

So, there is https://play.google.com/store/apps/details?id=com.globalcanofworms.android.proweatheralert , they have simple weather alert for free. I decided to pay for it after using it for one season. It is close to what your asking for. There is gps mode that takes your current location into account as it's checking for alerts, once watches or warning issued by nws, you get a notification. You can also configure dedicated counties or cities by zip. It is highly customizable, almost too much in fact. You can set urgency levels, quiet times, rules to over ride you phones silent mode, specify events, specify how the phone alerts you (light/vibrate/sound) just once or constant. I like it because it is light weight, extremely customizable, so far very reliable and cheap. My only complaint, which isn't really the fault with the app is that nws updates watches and warning so often that on some high tor% days it becomes more annoying than useful. However, being informed and annoyed is better than ignorant and dead. There maybe better options out there, but I've had no issues with this app. I've used it for about 3 years now, maybe longer.

Gotta make a plug for Nimbus Weather. It pulls National Weather Service forecasts, discussions, and radar for your area (or any other one you'd like to look up). The data itself may not be sexy, but the app has a good asthetic anyways. In some ways, I almost (almost) like it more than the NWS page itself.

It seems obvious to me but if you're not being facetious, you'll clamp the width of the door... it would obviously need to be in the opened position or removed in order to access the sides. Assuming this is a traditional, north american front door, you'll need a clamp with a 36" opening... something like this.

Buy something like this.

These are the ones I have been using this year, a little larger than the bags but they last almost a full day on the lowest settting and they have held up really well so far. I wear a XL pair of mitts and I put them between the liner and the glove. I had my doubts when I bought them but so far I'm very impressed with them.

A heat dome occurs when there is a large poleward shift in the jet stream, which becomes wavy and elongated. In this case, an unusually strong high-pressure system is forcing the jet stream well to the north, allowing warm air to funnel into Alaska from farther south, where temperatures into the 80s

I live in Ohio, this article popped up today and has some information about the system that you are looking at.

https://www.accuweather.com/en/severe-weather/daily-rounds-of-severe-weather-to-span-from-plains-to-the-appalachians/1211980

It's going to be a system that lasts a couple of days here but this article indicates that the setup has all the ingredients. A pretty strong cold front is moving in to Ohio Tuesday morning and is really going to make a mess. We've been in the mid 90s for some time now and this cold front is supposed to drop us 20-25 degrees.

Does your mom not understand how dangerous large hail is? There's been examples of larger hail crashing through people's roofs and ceiling. If it can do that, it can certainly do a lot of damage to a person's head.

And here's some video footage of it. I thought it was scud but at the end of that video clip it kind of looks like it tightens up and seems to "rope out" before it just dissipates. And now I'm not sure what to think.

No problem. And Calculus really isn’t that bad if you can find a good book on it. This one by Stewart is easily the best. If you want to ignore the math part then, you might be able to get away with simply reading the Holton book for its concepts and ignoring the equations. Up to you.

Just to preface, I’m not entirely certain that everything I said was correct since I’m not a professional yet. It takes at least a year before you can really grasp how all of this works and that’s if you’re very good at math. Sorry if that’s not an answer you were hoping for.

But to answer your question in one word: Holton

This is his book. I used to haaaaaate this book in my undergrad but have grown a strong appreciation for it as I got better at math.

Oh and make sure you know Calculus or that book is gonna be torture. Specifically, know Vector Calculus, Taylor Expansions, partial derivatives, Stoke’s Theorem, change of coordinates (into ones likes spherical coordinates or custom vertical coordinates), and relatively simple first order ordinary differential equations. A lot of things aren’t written out for you and are expected of the reader to know the intermediary steps. There really aren’t any good introductory books, but this is about the best one for both dynamics and thermodynamics imo.

Learned a lot of this stuff in college though, but if you wanna do so pedagogically that’s where I would start. Oh and do hand analyses of weather maps

Not sure what your budget is, but this weather station does rain, wind speed/direction, temp, humidity, solar radiation. https://www.amazon.com/Ambient-Weather-WiFi-Station/dp/B01N5TEHLI. It’s radio between the station and the indoor display, then the display has WiFi.

something like you search - android app for weather in multiple location. I think it's better for trips - you can add multiple cities with dates and see forecast + summary https://play.google.com/store/apps/details?id=me.weatheler

It's not often, but it has happened. They usually turn out to be impressive outbreaks. However, May 20, 2019 didn't pan out as predicted. There was somewhat of a tornado outbreak, but not many strong ones. Turned out the cap was stronger than predicted, and it didn't let the storms pop quite as strongly.

Recap of the day here:

Funny thing is, I live very close to where the tornadoes in SE Kansas went through. I was watching a KFOR stream out of Oklahoma, when my power flickered a few times and went out for good. That's when I heard the sirens blowing in town lol. 🤣

Hey just a curious question. What got you into climate/weather and what changes in weather have you noticed in your neck of the woods due to climate change? So two questions.

When I was in my 20s I was obsessed with weather. Actually it started when I was 7/8 with the weather channel.

Wunderground has/had some good blogs with very smart meteorologists that regularly post. You should check it out. https://www.wunderground.com/blog/index.html

Yea doesn’t seem it was once what it was. Tracked many a hurricane with tons of meteorologists and ppl going to school for it. Great memories.

It's a little on the technical side, but I've recently lost a few afternoons looking up all sorts of historical figures on the Iowa Mesonet webpage. You can get domestic US and many international stations hourly reports going back to the 1940s and daily reports going back to the late 1800s.

Again, the site isn't the most user friendly (it's intended more for researchers and meteorologists) but if you let me know what you're looking for I can show you which report to pull.

https://mesonet.agron.iastate.edu/

Also, while the website has been getting worse and worse, weather underground has historical data going back a decade or so for most stations and is much more user friendly to use. Search your city or zip code and click on the history option or monthly view and you can pull up historical data that way.

Check out Weather Underground to find dew points... here is a link to a specific forecast:

https://www.wunderground.com/hourly/us/il/schiller-park/41.95,-87.88?cm_ven=localwx_modtonight/date/2021-09-28

Look after midnight and follow dew point temperature as compared to actual temperature.. Closer the dew point temp gets to actual temperature, well, no running in the grass that morning (and if its a clear night- it may be a 5 degree difference due to radiational cooling).

Please note in the summer, besides the nights being generally warmer.. summer air has more water but less relative humidity at night (so relative humidity is how "full" is the air with water, relative to the actual temperature... so 70% humidity at 85 degrees F feels swampy, because 85 degree air can hold a lot of water, so 70% full is a lot of water... vs 70% at 30 degrees is not that much water- "relatively."

But these things have an effect on radiational cooling.. if there is more water in the air (like warm summers) the earth doesn't give off as much heat into space at night so the temperature drop at the surface isn't as big- so the odds of hitting dew point are lower and- well- more running in morning grass. In spring and summer- less temp at night means less overall water in the air- thus more radiational cooling on a clear night- thus bigger temperature drops at the surface- thus better odds at hitting the dew point and thus- wet feet.

Side note- once the air temp gets close to the dew point- the drop in the temperature (generally) slows down because the air can't go lower until it loses the water.. this is often how forecasters find the overnight low on clear, radiational cooling nights- look at the dew point forecast and maybe drop a degree or 2 below that. This is really useful when you're trying to forecast that first frost :).

Weather Underground has a "yesterday's radar loop" gif animation (was originally part of Intellicast, before they were taken over by Weather Underground)

Also the NOAA has static weather radar maps for every 5 minutes for the past several years.

I like it because it shows you much higher resolution radar than what you see on sites like weather.com The radar on your average weather site looks like amorphous blobs by comparison . The biggest selling point for me is probably the super res velocity data which helps you see rotation within a storm, which is crucial to pinpointing tornadoes. It also overlays warnings and watches and they always seem very up to date. With this app, i feel like you can see a lot of what the professional meteorologists see on radar that cause them to issue a tornado warning. I genuinely feel safer by having this app, and it even gave me the confidence to try a little storm chasing.

I get storm anxiety as well. This article helped me understand in data that getting "hit" by a tornado is pretty rare (0.06% chance per year in the middle of "tornado alley")

Im in NW GA and watching this system, will be another sleepless night for me. But knowing I have a plan to get me and my family into safety helps, and is the one thing you can absolutely control in this seemingly out of control situation.

That is pretty heavy snow. Here is a great article detailing some of the heaviest short term snowfalls ever recorded during lake effect snows. Heaviest hourly rate ever recorded: 12 inches.

The codes are near impossible to find for KY. However, if you go to https://weather.com/weather/today/l/USKY1096:1 , the USKY1096 is the code for Louisville. The codes go in alphabetical order. For instance, Bowling Green, is USKY0721, Lexington is USKY1079.

This is probably what it is. The edge can be very abrupt sometimes. Here's a similar photo from last year: https://weather.com/science/weather-explainers/news/2018-03-26-indiana-snow-edge-window-seat-winter-storm-uma

> in November 2014, parts of Buffalo, NY experienced NINE FEET of snowfall in the course of one night.

It sounds like your family was exaggerating. I haven't seen any documented cases of anywhere close to that amount of snowfall in a single night. The maximum amount recorded was 65 inches in 48 hours; combined with a second storm later that week the largest total was 88 inches in the full week.

I was very interested in that storm as it was occurring, and I don't recall seeing any photos of drifts 9 feet high, nevermind actual accumulation.

>Also, I know for a fact that the eastern ridges and flanks of the Sierra Nevada mountain range in Nevada have received nearly 6 feet of snow in under 24 hours

The Nevada side of the Sierras is the dry side, so I sincerely doubt that they are getting even close to that amount of snow in 24 hours. 6 feet is an insane amount of snow to fall in such a short time span, even for the Lake Tahoe area who are famous for their very deep snowfall accumulations. You need absolutely perfect atmospheric conditions to get greater than 3 inch per hour snowfall rates, nevermind to sustain them for an entire 24-hour period.

Measuring snow is not a simple process, and rigorous measurements are few and far between, so it's possible that these totals have been exceeded. But I also think you are seriously over-estimating the amount of snow that actually falls in these storms that you've witnessed, vs wind-drifting snow or snow piled by plows and backloaders.

It could be birds migrating, insects or some kind of particulate matter in the air.
