Chicago, IL – A sharp temperature change is approaching the Chicago area, with Veterans Day rain expected Wednesday before colder air brings overnight lows into the 20s in portions of northeastern Illinois later this week.
According to the National Weather Service in Chicago, rain chances return Wednesday, November 11, followed by blustery conditions Thursday and lake effect showers affecting portions of northwest Indiana and the southern Lake Michigan region.
Wednesday will be the warmest day of the four day outlook, with afternoon highs ranging from 52 to 60 degrees. Rain chances range from 30% to 70%, primarily across northwest Indiana, potentially affecting Veterans Day travel and outdoor observances.
By Thursday, November 12, temperatures will drop considerably, with daytime highs expected between 42 and 46 degrees. Overnight lows could fall to 27 degrees in colder locations, while other communities remain in the 30s.
The colder pattern continues Friday, November 13, with highs between 40 and 44 degrees and overnight temperatures ranging from 22 to 34 degrees across the forecast area.
Lake effect showers are expected mainly across northwest Indiana, where communities closer to Lake Michigan could experience changing precipitation conditions.
Saturday, November 14, offers some improvement, with partly cloudy skies and highs between 43 and 46 degrees. However, overnight temperatures are expected to remain chilly, ranging from 23 to 34 degrees.
Residents across Chicago, Cook County and surrounding communities should prepare for a noticeable temperature drop following Wednesday's milder conditions.
Drivers traveling into northwest Indiana should also monitor lake effect precipitation, which can create rapidly changing conditions along affected roadways.
