Summer isn't over yet in Chicago.

After a mild week with temperatures in the mid-80s, the mercury jumps on Thursday to the mid-90s under sunny skies with low to moderate humidity.

NBC Chicago meteorologist Andy Avalos says this will be the calm before the likely storm remnants of Hurricane Isaac hit Illinois.

Come Friday, sunny skies will be replaced by clouds, humidity and a weak front of rain in the afternoon, Avalos says. Temperatures turn cooler in the evening, and an isolated shower or thunderstorm could move in.

The potential for heavy rain increases in southern counties and Northwest Indiana by Saturday evening and continues overnight as the remnants of Isaac passes south of the metro area. Rain and storms remain during morning hours and could become heavy in southern counties and farther east.

Clouds show up later Sunday, and conditions become humid with a few lingering showers and storms in the afternoon.

Avalos says a few isolated showers or storms could hang around for Monday, but most of the day should be dry, partly sunny and humid with highs in the low to mid-80s.

Until then, Chicago deals with a mini-heat wave well into the 90s. It's a noticeable jump but remains relatively mild compared to the steamy summer's record-setting, triple-digit temperatures.
