Weatherback Wallpaper is the coolest app I've found in WEEKS. Using any static wallpaper, it uses the current weather to apply effects to your background. It's not animated, so it doesn't use a ton of battery. This is my screen this morning (it's snowing).
Mine is under Settings>Display>Lock Screen>Weather Animation.
I suppose it could be regional, but I can't imagine why.
Edit: the app Weatherback is similar.
I'm currently using Weatherback. It overlays whatever wallpaper and lock screen you choose. Desaturates and darkens it at night, sunbeams in clear weather, raindrops when rain etc. Good range of configurable options. Free version is good enough for me, but you can purchase additional packs to get better looking rain etc
You can use this app and set it as your lockscreen wallpaper. It will just add the overlay on top of whatever static wallpaper you already have set. It's not animated but it looks nice and works well for me.

Basically it just adds static raindrops/snow/sun effects depending on the weather on your location. It also doesn't poll your location 500 times per minute, so it isn't a battery drainer at all.
I'm using Weatherback. it's awesome.

Weatherback does this, but it doesn't apply only to the lock screen. I like it a lot, anyway.
