I'll admit it: I'm a bit of a weather nut. Besides Apple's included Weather widget, I also run one that displays an animated version of the current radar image. But it's not nearly as cool as the Weather Channel's new Interactive Map, built on top of Microsoft's Virtual Earth technology.
Like you might expect from Google Maps or MapQuest, the Interactive Map lets you drag, or zoom in and out to an impressive degree, all the while superimposing either cloud cover or radar maps. You can choose between road maps or satellite maps, and even adjust the level of transparency for the radars and clouds. Like the existing maps, it also has controls for the animation, letting you step back and forth to see how the weather's moving.
So if you're not satisfied by your current map technology because it doesn't let you see what the weather's doing, say, down the street, this could just the thing sooth that annoyance. The Interactive Map's in beta right now, so if you see something that irks you, don't hesitate to give the Weather.com folks a buzz. Tell 'em Gadgetbox sent you.
