Severe thunderstorm warnings popped off in the greater Chicago area through the evening Thursday, forcing the evacuation of tens of thousands of people from the Windy City Smokeout.

Chicago faced a stormy weekend with severe weather threats, including hail and gusty winds, according to forecasts.

More than a month's worth of rain fell on Chicago in 90 minutes on Tuesday evening, according to the National Weather Service (NWS). "There were numerous reports of flooded viaducts, several reports of water rescues, and a few reports of flooded basements," the NWS said.

Friday, temperatures are expected to reach the mid 80s with a 40 percent chance of heavy rain. Saturday, the chance of thunderstorms is 50 percent with highs in the upper 80s.

The opener of a four-game series between the Cleveland Guardians and Chicago White Sox has been postponed because of rain.

Weather in the area delayed the start of Sunday's game between the Cubs and Cardinals, which was scheduled to begin an hour late, at 6:10 p.m.

Snow seasons in Chicago are tracked from July through the following June. The area normally can expect 38.4 inches.

Along with the chance for storms, there will be HEAT in the forecast Friday with highs in the low to mid 90s. High temperatures will be in the upper 80s this weekend with the better chance for storms on Saturday.
