I like this one. Am a sucker for the most information possible crammed into as little space as possible.

I really like that little DeLorean flying Back to the Future car in the Weather Timeline.
On my tablet, however, I'm using the free YR weather widget HD. It's a permanently pinned meteogram to my Samsung start screen . Shows the weather over the next 2.5 days, and the meteogram shows the temperature as a curve, shows cloud density, rainfall, and wind direction as arrows. In addition the YR widget is based on very accurate forecasts. I've set my update to every hour.

Been using this for years, tuned to the Norweguan met service. Love it.
