After a very comfortable late-summer Friday for the Chicago area, temperatures warm up a bit on Saturday ahead of oppressive heat that is expected to impact the region Sunday and again from Tuesday to Thursday.
The mid-morning hours on Saturday begin with partly cloudy skies and temperatures in the low 70s.
Warmer conditions are expected as the day goes on, with readings anticipated to climb into the mid 80s for much of the region by the late afternoon, when some of the cloud cover may dissipate as well.
From there, temperatures will descend back into the low 70s, where overnight lows are expected before extreme heat moves into the region on Sunday.
In areas away from the lakefront, Sunday's heat could bring heat indices into the 100s, with temperatures in the 90s anticipated for many in the Chicago area.
Though the heat and humidity that poses a threat on Sunday is likely to subside on Monday thanks to a cold front, the balmy temperatures will return from Tuesday to Thursday, when highs in the low-to-mid 90s are expected each day.
