Eruption of Massive, Tornado-Spawning Thunderstorms Captured in Spectacular Satellite Animation

Uncategorized | Tagged ,


Operating in a special mode, the GOES-14 weather satellite captured a stunning animation of the birth and growth of massive thunderstorms over the Upper Midwest yesterday. Click on the image above to watch it.
The thunderstorms spawned tornadoes, large hail, tree-toppling winds, and widespread power outages.  But so far the storm system has failed to produce a derecho — a widespread, highly damaging cluster of thunderstorms arrayed in a line. Forecasters had warned that formation of a derecho was possible.
After their birth over parts of Minnesota, Iowa, Wisconsin, and Illinois, the huge thunderstorms moved east. They’ve now barreled into the mid-Atlantic.
To record the birth and evolution of the storms in detail, the GOES-14 satellite was put into a special mode in which it captured images at a rate of one per minute, as opposed to the normal 15 per minute.
