As an alternative to his recommendation of Apple Weather for generic weather info, I'd highly recommend weawow, or QuickWeather (available in f-droid).
Easily the best two weather apps I've tried on android.
I've always liked myradar on android. Been using it for a few years now and love the detailed weather maps where i can easily tell when its gonna rain and when it will stop. For simple Forcast I just use Googles built in weather.
With that said I tried out windy from the articles suggestions and really liked it's simplicity and it also has nice weather maps in real time. I'll have to try it out the next time I expect rain to see how it looks.
