BBC weather for a good overview and Met Office for good real-time maps of rainfall.
I love the simple, clear yet attractive design and it gives plenty of detailed information - such as hourly forecasts up to 14 days ahead for the UK.
Best of all, thanks to BBC licence payers (such as myself), there's no ads to be found anywhere in the app.
BBC Weather is a great app, I use it on my phone: https://i.imgur.com/Be08p2d.jpg | https://i.imgur.com/7KLEwZF.png

Easy to read format with good information.
This rules in the UK. YMMV
