Mon, September 26:
Good Monday morning! Classic fall weather is here all week, with highs in the 60s and lows in the 40s. We should be dry through the end of the week with plenty of sunshine. A bit breezy today!
Much of the day will be quiet & dry across central Illinois, but the chance for scattered thunderstorms, a few of which could be severe, increases quickly after sunset.
Thunderstorms are expected to develop near the Iowa and Illinois border late this afternoon, the strongest of which may produce hail over 2", wind gusts over 60 MPH, and an isolated tornado or two.
Storms are then expected to shift southeast into central Illinois late this evening into the early overnight. After dark it's likely that the risk for large hail and tornadoes will begin to fade, and damaging winds/heavy rainfall are likely to be our biggest risks in Champaign County/east-central Illinois should storms survive into our backyards.
Right now, the most likely time frame for any severe storms in the immediate Champaign-Urbana area appears to be between 8 PM and Midnight. It is also quite possible that storms weaken or shift further southeast and miss our area - we are absolutely on the back-end/afterthought part of this storm system, with the greater risk for severe weather found in the 'Enhanced Risk' area to our northwest.
