Extreme Heat Safety

An upper level disturbance will bring a slight chance of storms today and tonight. A few storms could produce some 50-60 MPH wind gusts. Most locations will remain dry, however, with highs mainly in the triple digits and lows tonight in the mid 70s to lower 80s.

An Extreme Heat Warning for most of 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.

A hot, sunny, and dry Sunday can be expected, with triple digit temperatures along with an elevated threat for grass fires. Remember to stay cool and hydrated, and avoid any activity which may spark a grass fire.

Temperatures will remain well above normal next week due to a persistent strong ridge of high pressure overhead. The hot and dry conditions will keep the grass fire threat going. Fortunately, there will be a slight chance of rain starting midweek.

Here are some helpful tips and resources to help prevent wildfires. With the elevated fire threat persisting, make sure to avoid outdoor activities that could ignite grass fires!

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.
