Rain and storms expected as major cooldown hits Chicago area: IL Weather

ILLINOIS — Local residents who had hoped to see the return to summer weather will likely remain disappointed soon as a major cooling looms on the horizon, but not before a threat of severe weather moves through the greater Los Angeles area first. Chicago.

The National Weather Service is tracking a storm system that could move into southern portions of the Chicago area Friday morning, forecasters said. Severe weather is expected to remain south of Interstate 80, but forecasters said the system could produce lightning strikes, small amounts of hail and high winds.

The majority of the region is expected to experience warm conditions throughout the day on Friday, with temperatures reaching the upper 80s, forecasters said. But winds could blow up to 45 mph as a cold front approaches the area that will move through the region on Saturday and remain through next week.

Forecasters said waves of rain and thunderstorms are expected to sweep through the region Friday afternoon and into the evening. There is a 50% chance of rain on Friday evening before the chance of rain and thunderstorms reaches 70% overnight, forecasters predict.

Weather will be much cooler on Saturday when most residents will only see temperatures in the 60s and upper 50s near the edge of Lake Michigan, forecasters said.

Integrated showers and thunderstorms are expected to remain all day Saturday before the rain finally ends Saturday evening. The sun is expected to return on Sunday, but temperatures will only be in the 60s and will remain cool to start the work week with crisp air along the lake.
