Here is the site for free downloads from Everything Q. After you login you can get a weather version for your home screen; however, you have to pay $16 or so for Fizz Weather.

If you don't want it on your home screen, there are tons of Smartphone internet options if you have a good data plan. I personally like WeatherBug because of their animated maps which is around $16 as well. Check out Accuweather and The Weather Channel.
Here is a free download from CNet:
