Weather Bomb

Strong Extratropical Cyclone Over the US Midwest

Oh, so that’s what hit us. This image of the “weather bomb” that surprised the U.S. Midwest and much of central and western Canada — it knocked out our power a couple of times earlier this week — was taken on October 26, 2010, by NASA’s GOES 13 satellite, I believe.

Update: Earth Observatory has animation showing the development of this extratropical cyclone.
