An Extreme Heat Warning along and near the I-20 corridor and a Heat Advisory for elsewhere across North and Central Texas remain in effect through 8 pm tonight. Remember to stay hydrated, and take frequent breaks in the a/c if weekend outdoor activities are planned.

An upper level disturbance will bring a slight chance of storms this afternoon and tonight. A few storms could produce some strong to severe 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.

A dangerously hot Sunday can be expected as temperatures and heat indices peak between 103-110 degrees. Elevated fire concerns persist region-wide. A very low (10%) chance for isolated storms exists in East Texas, though most will likely remain dry.

We'll start this upcoming week off with what will likely be the hottest days of the summer so far. Expect dangerous heat for much of this upcoming week with highs and heat indices remaining in the triple digits, up to near 110. Elevated fire weather concerns will persist amid dry early week conditions, however, low daily isolated rain chances return Wed-Fri.

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.
