Heat Wave Continues Into Third Day For Chicago Area

ILLINOIS — "Oppressive heat and humidity" is expected Monday as the multi-day heat wave continues for the Chicago area, the National Weather Service said.

Peak heat indices are expected to be over 100 degrees in the afternoon in places like Midway, O'Hare, Aurora, DeKalb, Dixon, Joliet, Kankakee, Ottawa, Rockford and Woodstock.

The heat advisory and extreme heat warning will still continue through Monday and remains in effect until midnight for the Chicago area.

"Chances for storms return to the area as early as Monday evening, but more likely from Tuesday onward," the weather service said on its Facebook. "Local relief from the heat also arrives Tuesday along the lakeshore and near the Wisconsin state line, though toasty conditions will continue for other parts of our area."

Continued warm and humid conditions are expected the rest of the week, with on-and-off thunderstorms, according to the current forecast.

Storms could be strong to locally severe, but plenty of dry hours are expected in between rounds of storms, the weather service said.
