Chicago, IL – A sharp overnight temperature drop is expected across northern Illinois tonight, with some communities potentially falling as low as 26 degrees before Saturday morning. The coldest conditions are expected where skies clear, bringing freezing temperatures to portions of the Chicago metropolitan area and surrounding communities.
According to the National Weather Service in Chicago, temperatures will fall into the upper 20s in areas where cloud cover clears Friday night, Nov. 6, before a brief cold snap gives way to warmer weather early next week.
Temperatures Could Fall Into the Middle 20s Forecasters expect overnight lows ranging from 26 to 38 degrees across the region, with the coldest readings most likely away from the moderating influence of Lake Michigan.
Chicago and communities closer to the lakeshore are expected to remain warmer than some inland locations.
The National Weather Service says the coldest conditions will depend on overnight cloud cover, which could influence how quickly temperatures fall.
Saturday morning lows are forecast between 31 and 39 degrees, followed by readings between 31 and 40 degrees Sunday morning.
Temperatures Climb Into the 60s by Monday Despite the overnight chill, the cold snap is expected to be short lived.
Saturday afternoon temperatures should reach 49 to 52 degrees before climbing into the upper 50s and lower 60s Sunday.
By Monday, highs are forecast between 60 and 66 degrees across the region.
The National Weather Service also indicates that no rain or snow is expected anytime soon.
Residents with sensitive outdoor plants should consider protecting them Friday night, particularly in inland communities where temperatures could fall well below freezing.
The warming trend is expected to bring noticeably milder conditions across northern Illinois heading into the new workweek.
