Extreme Heat Safety

An Extreme Heat Warning remains in effect through 8pm Friday for North Texas, where afternoon high temperatures up to 108 degrees can be expected. A Heat Advisory remains in effect through 8pm Friday across Central Texas, where afternoon heat indices up to 109 degrees can be expected. Remember to drink plenty of water, to take frequent breaks in the shade or A/C, and to look before you lock your vehicle!

Exceptionally hot weather will persist over the next few days, with triple-digit temperatures expected each afternoon. However, an upper-level disturbance and a stalling front will bring a slight chance of storms to the region. The main concern with any storm that forms will be gusty downburst winds and frequent lightning. Should you see a storm, remember: “When thunder roars, go indoors!”

Temperatures will remain well above normal due to a persistent strong ridge of high pressure overhead, though a slight chance of rain could return by the middle of next week.

As we head into late August, we are continuing to see temperatures 10-15 degrees above normal. The forecast highs this weekend are even expected to tie or exceed the record daily high in DFW on Saturday and Sunday! This abnormal pattern is expected to continue into early next week.

Heat can escalate quickly. Warm temperatures can quickly become dangerous. Heat is one of the most deadly weather hazards - don't underestimate it. Never leave people or pets alone in a car. Drink plenty of water, even if you don't feel thirsty. Wear loose-fitting, light-colored clothing. Spend time in air conditioning and in the shade.
