After a push of cooler, less humid air, more late-summer heat and high humidity will return to Chicagoland, just in time for the start of the new school year in many areas.

Don't put away the bathing suits and air conditioners just yet.

After cooler air pays a brief visit, heat and high humidity will return to the area.

Temperatures will climb through the 70s and into the 80s for the Life Time Triathlon on Sunday.

While autumn weather is still expected to arrive early this year, the atmosphere will attempt to make up for cool weather during recent weeks with a late-season heat wave during the last week of August into the first few days of September. Summer 2013 does not officially end until Sept. 22.

The outlook for this week projects multiple days with high temperatures into the lower 90s. However, when factoring in sunshine, humidity and light winds, RealFeel® temperatures are likely to surge into the upper 90s to near 100 degrees for a couple of hours each afternoon.

For Chicago and many areas in the Midwest, the pattern next week will be the warmest weather since the heat wave during the middle of July, when temperatures climbed into the middle 90s.

The core of the heat wave will be centered west of Chicago. Actual high temperatures can reach 100 degrees in Omaha, Kansas City, and Des Moines, Iowa, to name a few cities.

Public schools in Chicago are scheduled to begin classes on Aug. 26.

At least many families will be able to enjoy the warmth over the Labor Day weekend with high temperatures at or above 90 degrees projected through Monday.

Most days this weekend through the Labor Day Weekend are likely to be free of rain.
