Symptoms of Overheating

Triple digit temperatures and heat indices will once again return to most of the area by the afternoon.

Widely scattered showers and thunderstorms are possible in parts of Oklahoma on Friday. Unfortunately, rainfall totals will be light, providing little relief to ongoing drought. A few strong storms will be possible during the late morning and afternoon.

A persistent hot and dry pattern will elevate fire weather conditions by the end of the weekend into early next week across all of western Oklahoma and western north Texas.

Know the signs of your body overheating before it becomes to late.
