Showers and thunderstorms will continue to track across central Illinois overnight. Primary hazards with any of the stronger storms will be gusty winds, small hail, and locally heavy rainfall.
Strong to severe storms this evening will give way to a sharply colder day on Friday. A hard freeze is likely Friday night north of I-72. If you have any tender vegetation that got a jump start from the recent warmth, take precautions to protect them. Dry conditions are expected this weekend, with sunshine on Saturday and increasing clouds on Sunday. Much warmer air returns Monday and Tuesday as the next wave of rain and storms arrives.
