Thursday. June 21
Summer Solstice today. We won’t see much of the sun with mostly cloudy skies an d widespread showers or thunderstorms as a “stacked” low pressure system tracks through southern Illinois. Locally heavy rains in excess of 1-2 inches will cause flooding in some areas.
Continued on the cool side with afternoon highs in the middle 70s inland – about 7° below normal for this date and much cooler at the lakefront.
