iPhone Giveaway of the Day - Upweather - beautiful weather

Upweather brings you the freshest weather imagery available for North America, and lets you animate it at your own speed. Watch hurricanes roaring in off the ocean, or thunderstorms forming in the midwest. See how the shape of upper air features steers the weather we experience.
