Dallas is starting Monday with possible isolated precipitation during the early morning, but the calm morning will give way to another hot afternoon. Temperatures are expected to climb to about 97 degrees. A few showers and thunderstorms could develop after lunch, giving the day a brief shot of drama before drier weather settles in.

Storm Chances Arrive After 1 p.m.

The National Weather Service in Fort Worth puts the chance of rain at about 30% Monday afternoon and evening, with storm activity expected mainly from mid-afternoon into the evening before progressing south by late evening. Storms should be scattered rather than widespread, but a few could produce strong downburst wind gusts or small hail, according to the National Weather Service.

Winds will begin light and variable before shifting toward the north or northeast later Monday as a weak front moves through. No watches, warnings or advisories were listed for the Dallas forecast area, but outdoor plans should allow room for a quick change in conditions.

Hot Tuesday Before A Drier Stretch

Tuesday will be mostly sunny with a high near 96 degrees. Rain chances will drop sharply, with only a small possibility of showers or storms mainly west and southwest of Dallas.

From Wednesday through the weekend, highs should remain in the low to mid-90s under mostly sunny skies, while drier air brings less oppressive humidity even as temperatures stay above normal for late September.

Plan Around The Afternoon Heat

For Monday, the most comfortable window for outdoor errands will be the morning, before temperatures surge into the 90s. Anyone spending time outside during the afternoon should drink water, take breaks in shade or air conditioning, and keep an eye out for rapidly developing thunderstorms.
