Extreme Heat Safety

An Extreme Heat Warning for North Texas and a Heat Advisory for Central Texas both remain in effect. Remember to stay hydrated, and take frequent breaks in the a/c if weekend outdoor activities are planned.

Exceptionally hot weather will persist throughout the weekend, with afternoon temperatures climbing well into the triple digits. In addition, an upper-level disturbance and a weak frontal system will create periodic chances for storms. Some of these storms could become strong, producing gusty winds and frequent lightning.

Temperatures will remain well above normal next week due to a persistent strong ridge of high pressure overhead. The hot and dry conditions may increase the threat for grass fires. Fortunately, there will be a slight chance of rain by midweek.

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.
