Illinois Tornado, Severe Threat Today and Heavy Rain Potential
Wednesday, September 26th, 2012
Strong to severe storms popped up across the central part of the country yesterday. Some of the storms produced hail and high winds, but this particular storm near Okawville, IL produced a nice looking tornado!
On The Ground!
Imagine a bank of trees in the foreground… If you couldn’t see the ground and debris being kicked up, you would most likely think that the image below was just a funnel cloud since the condensation funnel is only seen in the blue outlined area. We can tell that this is a true tornado because circulation is seen on the ground as dirt and dust debris(outlined in yellow) is being kicked up! There are also larger chunks of structural debris (outlined in red) floating around the tornado, likely from some outbuilding either sheet metal or lumber… it could even be trees!

Storm Reports From Tuesday
There were 7 official tornado reports, those are likely multiple reports from either one, possibly two tornadoes from Tuesday. Unfortunately, there was a minor injury reported 1 mile North of Okawville, IL as a semi was blown over on I64.
The severe weather threat today is in nearly some of the same areas as the slow moving/stalled frontal boundary through the central part of the country. Hail and high winds will be the primary threat along with the heavy rain, but an isolated tornado can’t be ruled out!
Heavy Rain Potential
There have been several heavy rainfall reports already along with some of the strong to severe thunderstorms, but more heavy rain is possible over the coming days. NOAA’s HPC 3 day rainfall suggests an additional 1″ to 3″ + possible across parts of the Ohio Valley and the Central/Southern Plains. Minor flooding is possible in areas that experience heavy downpours in a short amount of time.
