Isolated Showers Possible Overnight

Skies were filled with sunshine Tuesday afternoon as temperatures warmed area wide into the low to mid 80s. Just a few clouds developed during the afternoon and evening, while isolated thunderstorms developed up north.

An upper level disturbance and weak cold front will continue to move east and south Tuesday night into Wednesday. A slight increase in moisture has allowed a few more clouds to spread across northern Illinois and southern Wisconsin, but skies remain dry. Isolated showers are possible overnight, most likely after Midnight and closer towards daybreak Wednesday, but the overall coverage of any precipitation will remain fairly limited.

As the cold front comes through Wednesday an isolated shower/storm will develop, but remain mostly confined along and south of the I-88 corridor. Overall rainfall amounts from Tuesday night, Wednesday and Thursday will likely remain under a quarter of an inch.
