A couple of severe storms recently passed through Boone County, Missouri - Columbia's county. A fellow who goes by the handle kctgrs on Tigerboard posted the following three pictures there.
That cloud tail trailing from the upper left to the center is very odd.
The fellow wrote in one of his posts that he lives in the north part of the city. According to the national weather service, a tornado touched down for a brief period in the east central part of the city late this afternoon.
Update: A third round of severe storms have popped up again around Kansas City. This is the radar from 7:03 PM CDT, and more tornado warnings have been issued. This looks like a weekend that will be talked about for ages.
Here's a National Weather Service summary of today's action in Missouri.
