A strong cold front will sweep across the Chicago area this evening ushering in drier and cooler air for the weekend.
As the front passes through the region, scattered strong thunderstorms are expected to develop between 3 p.m. and 6 p.m. The storms should then quickly exit the area between 9 p.m. and midnight.
Due to a lack of strong frontal convergence, the storms that do develop are expected to be of the “scattered” variety, meaning some Chicago area towns and neighborhoods may miss out on the rain altogether. Those that do see the storms can expect heavy downpours, frequent lightning and gusty winds.
A few of the storms may turn severe, with wind gusts in excess of 58 mph.
A heat advisory remains in effect for the Chicago area until 7 p.m. Friday.
