Microburst Hits Tea Area
June 28, 2010, 6:06 PM
Friday evening's storms became tornadic on the Iowa border. The concern was the storm on the very end of the line.
Typically, storms on the end of the line pose the highest risk, which quickly became the case as a tornado touched down just west of Little Rock just before 10 PM and moved east toward Sibley. Doppler radar shows how the winds were rotating in the hook echo.
And at one point, you can actually see a donut hole in the middle of the hook right where the center of the tornado is located.
By contrast, straight line winds caused much of the damage Saturday night, although the storms seemed like they could produce a tornado at any time.
A microburst detected over Tea produced winds more than 80 mph. The signature on the doppler radar shows the diverging winds over the town.
The same was true for the Harrisburg area. Straight-line winds were intense, but peaked near the Lake Alvin area where doppler radar shows near 90 mph winds from the northwest.
