A flash flood warning has been issued for parts of the Chicago area on Thursday night as heavy rain continues to fall across the region.

A spring-like storm is moving in from the Plains. Rain showers began in the afternoon and increased as the evening went on. The National Weather Service issued a flash flood warning until 10 p.m. for central Cook County, DuPage County, and northwestern Will County, due to rainfall as heavy as 1 to 2 inches per hour in some areas.

Rain totals could reach upwards of 2 inches, and temperatures will peak near 60 degrees overnight. 

Areas southwest of the city and in Northwest Indiana can expect a severe storm threat.   

There is a low, but present, chance of damaging wind gusts and isolated tornadoes between 6 p.m. and 10 p.m., especially southeast of Chicago. 

Rain will end as temperatures cool, and Friday will stay gray and damp, with louds of clouds and possible drizzle, but not the soaking rain and storm threats of today. 

A second, more wintry system is coming on Saturday.

Rain late Friday night changes to periods of wet snow by Saturday morning. While there is still uncertainty in exact timing and coverage, light accumulations are expected, generally under 1 inch.

Totals of 2–3 inches of snow appear possible near the Wisconsin state line.

Bears fans will need to dress for winter as the Bears take on the Green Bay Packers in the NFC Wild Card Playoffs Saturday night at Soldier Field, with snow and blowing snow possible.
