Weather Underground offers an excellent mobile forecast tool.

With the latest winter snow storms, it is not a bad idea to have a reliable weather forecaster tool right on your cell phone. But with the plethora of weather apps available, it can be confusing to decide which one is right for you.
Two weeks ago, the New York Times reviewed and gave high marks to the mobile Web page of a weather site called Weather Underground, generally refered to as Weather Underground Lite.
According to the Times, this is not technically an app, but can be made to one thanks to the shortcut features on today's phones.
The site is accessible at m.wund.com from a cell phone and it delivers an easy to read weather report and forecast. Still according to the New York Times, you can link to more sophisticated features like an animated radar map. But one downsize is that weather Underground works better with some phones than others. Google's Android phones do not make it unto the former list. On the other hand, the Weather Underground version for iPhone called i.wund .com, contains extra links and features.
