My friend Curt has been encouraging me to create a mashup with radar, temperature, and other weather related features for the last few months. Come to find out Weather Underground now has these features on a Google Maps mashup! You can see Washington, DC in the screenshot below. Looks like airports get the “sunny” status icons where most other weather stations track temperature, some wind direction. There is a sidebar (not shown here) that lists all the stations alphabetically. When station names are mouseOver’d there the station will highlight on the map. When a storm passes thru, the map updates with the latest radar. Thanks Curt!
