Chicago, IL – Much of the Midwest is bracing for the season’s first hard freeze later this week, with temperatures expected to dip into the 20s and 30s across Illinois and Indiana by early Friday morning.
According to the National Weather Service offices in Chicago and Indianapolis, scattered showers will taper off Tuesday night before colder air surges into the region. Overnight lows are forecast to range from the upper 20s to low 40s, with the coldest readings expected outside the Chicago metro area and across northern and western Indiana.
The Chicago Weather Service noted that frost is likely Wednesday night into Thursday morning, especially in outlying areas and near the suburbs. A broader freeze risk is expected Thursday night into early Friday as temperatures drop into the upper 20s and low 30s.
Meanwhile, the Indianapolis office reports frost is likely Wednesday night, with the highest chances for sub-freezing temperatures Thursday night through Saturday morning. Areas such as Lafayette, Terre Haute, and Muncie could experience multiple frost or freeze events through the weekend.
Residents are advised to cover or bring in sensitive plants, disconnect outdoor hoses, and protect any exposed plumbing as temperatures dip below freezing for the first time this fall.
Cool and breezy conditions will continue into the weekend, with highs gradually rebounding into the 50s by Sunday.
