Showers and embedded thunderstorms are developing and moving east about 40 miles per hour across northern Illinois this Monday evening. A few of the strongest storms could have wind gusts to 45 miles per hour, and small hail in addition to brief heavy downpours and vivid lightning.

This band of showers/thunderstorms is associated with low pressure moving east out of Iowa, the warm front that extends east across northern Illinois and the cold front just now crossing the Mississippi River.
