Thunderstorms produce overshooting tops in Wisconsin

What’s an overshooting top you say? First, take a look at this visible satellite view from Exactrack|HD just a few minutes ago.

overshooting
I’ve given you a hint where to look with the blue arrows. Intense updrafts from thunderstorms are sometimes able to push air and water out the top of the troposphere (the lowest level of the atmosphere). Because the water isn’t as bouyant at this elevation, it descends back. But just imagine, if it was possible to be at the top of this thunderstorm, the sky wouldn’t be blue…it would be black!

Cool feature that you can see on the satellite at sunset (and sometimes at sunrise, although storms aren’t nearly as strong in the morning). -Eric
