Late-Summer Heat Wave Baking Chicago

Despite other signs of summer winding down, summer heat is in full swing in Chicago.

Public schools in Chicago resume classes on Monday and Labor Day, the unofficial end to summer, is just around the corner.

However, Chicago is in the midst of its hottest stretch of weather since the middle of July. Similar to Sunday, temperatures Monday and Tuesday are expected to soar into the lower 90s.

Combining the heat with sunshine and high humidity will send RealFeel® temperatures into the upper 90s to near 100 degrees each afternoon.

Anyone spending a considerable amount of time outdoors should use caution during this heat wave by avoiding strenuous activities, drinking plenty of water and wearing light clothing.

Coaches of fall sports teams should ensure their players are taking these necessary precautions. The mornings and evenings would be better times for outdoor practices than the sizzling afternoon hours.

The tail-end of a cool front will cross Chicago Tuesday night, possibly triggering a stray shower or thunderstorm and knocking down high temperatures slightly for the latter half of the workweek.

The term slightly should be stressed with humidity remaining high and temperatures still set to climb into the upper 80s Wednesday through Friday.

Ninety-degree heat is then set to make a comeback for Labor Day weekend, keeping air conditioners and swimming pools busy.

This week's heat wave may seem like the atmosphere's way of making up for the cool weather from recent weeks, stated Expert Senior Meteorologist Alex Sosnowski.

Since the mid-July heat wave, temperatures from July 20 to August 24 in Chicago averaged 2.7 degrees below normal. The Long Range Forecasting team also expects an early arrival of autumn weather this year.
