After reaching 100 degrees Sunday for the first time this year, we should do it again Monday before enjoying a serious reprieve from the summer heat.

Many communities are opening cooling centers for residents who don't have access to a working air conditioner. The Salvation Army operates 15 such relief shelters around North Texas.

An unusual July cold front will cause highs to drop into the 80s and lows into the 60s.

The front will also bring a prolonged chance for rain, mainly on Wednesday, Thursday, and Friday.

Isolated pop-up storms are also possible on Monday, but they are more likely to produce strong wind and lightning than any significant rain.
