North and Central Texas

Stifling and dangerous heat returns early this week as an upper high re-strengthens overhead. An Excessive Heat Warning is in effect through 9:00 pm Tuesday for the southern and western parts of the area, including the DFW and Waco/Temple/Killeen Metro areas. A Heat Advisory is in effect through 9:00 pm Tuesday for northern and eastern parts. Lastly, an Ozone Action Day is in effect for DFW and surrounding areas due to poor air quality from elevated ozone levels. Take extra precautions if you work or spend time outside. Wear lightweight and loose-fitting clothing, stay hydrated with water, and take frequent breaks in the shaded, or better yet, a vehicle, building, or home cooled by air conditioning. These are good practices to avoid heat-related illnesses.

Heat highlights are in effect early this week as triple-digit heat returns to North and Central Texas. An upper high-pressure dome will shift back east and strengthen over the area through midweek. It will result in temperatures ranging between 95-100 degrees in the northeast zones to between 103 and 110 degrees elsewhere. Where humidity is higher across the eastern half of the area, heat index values will range between 105 and 113 degrees. Lastly, the dry, very hot, and sometimes breezy conditions will elevate to critical fire weather conditions across the western half of the region (shaded area). Remember to use your heat rules to avoid heat-related illnesses!

Keep your loved ones safe during the summer heat by practicing good heat safety routines. These include drinking plenty of water, wearing light-colored and loose-fitting clothing, spending time in an air-conditioned building and the shade, and never leaving people or pets in a closed car.
