A Heat Advisory is in effect through 9 pm this evening. Expect heat index values up to 107 degrees with temperatures of 94 to 103 degrees. To beat the heat, drink plenty of water, limit time outside to the cooler part of the day, and know and recognize the symptoms of heat illness.

Rain chances are expected across the region on Saturday, with the best rain chances in East and Central Texas. Even with slightly cooler temperatures on Saturday, it will still be uncomfortably humid, pushing heat indices up to around 107 in portions of North Texas. A Heat Advisory is now in effect from 9 pm tonight through 9 pm Saturday for portions of North Texas.

Summer heat continues through the end of the month with highs in the 90s to lower 100s and heat index values up to 108 F. Apart from low storm chances across the Brazos Valley Sunday afternoon, most areas will be rain-free Sunday through at least the middle of next week.

Here are some friendly reminders on how to protect yourself from the heat! Wear lightweight, loose-fitting, and light-colored clothing to reflect heat and sunlight. If you will be spending time outdoors, hats are also a good idea to protect your face and scalp from harmful UV rays. Don't forget the sunscreen.

Everyone is at risk from the dangers of the heat, but these groups are more vulnerable than most. Ensure that your loved ones and neighbors are safe from the heat and remain Weather-Ready.
