Beweather is really cool, check it out at the play store. It's pretty cool when there's a storm out, it flashes lightning and water drips down the screen.
I havent used it in a while but it was slow to update at first, I had to tweak it a bit and it was A-OK. I have the pro version maybe the free one is limited, not sure. I also used it in conjunction with Beautiful Widget so it would open Beweather on tap and that worked fine. Let's us know if you find anymore.
