It was a warm and muggy day, but despite lots of sunshine this afternoon our weather will be very active this evening and tonight.
Thunderstorms will begin to move into the area as early as 7-8 PM, but will become more widespread by 9-10 PM.
Initially, discrete supercells capable of producing tornadoes look to be possible. As we head into tonight, thunderstorms will likely take a more linear form. I think the transition from supercells to a squall line will occur after midnight.
Our severe weather threat will continue through about 2-3 AM, and then storms will exit the area to our east.
Areas along and south of I-74 will have the best chance of seeing severe weather, including the risk for tornadoes. However, all modes of severe weather will be possible including hail upward of 1-2″ and winds as high as 60-70 mph.
Make sure you have ways to get warnings throughout the evening and overnight, and stay with Heart of Illinois ABC and Storm Team ABC for the latest updates.
