Dallas is starting today with clear skies and temperatures in the mid-80s, but the city is headed for a dangerous 106-degree afternoon. An Extreme Heat Warning is in effect through 8 p.m., with the heat index expected to reach 111.

Extreme Heat Warning Runs Through Thursday Evening

South-southwest winds around 5 to 10 mph will offer little relief as temperatures climb past 100 degrees during the afternoon. The most intense heat is expected from roughly 2 to 7 p.m., when outdoor work, exercise, and errands become significantly riskier.

The warning marks a more serious escalation from the earlier Dallas heat outlook covered by Hoodline. Residents are urged to drink water, take frequent breaks in shade or air conditioning, and check on relatives and neighbors.

Another 106-Degree Day Follows Friday

Tomorrow will be just as hot, with sunny skies and a high near 106 degrees. The heat index could climb as high as 113, while a slight chance of showers and thunderstorms arrives after 1 p.m.

Most of Dallas will likely stay dry, with only a 20% chance of rain. Any isolated storm could produce a sudden strong wind gust, but it is unlikely to provide meaningful relief from the heat.

Triple-Digit Heat Holds Through Next Week

Saturday through next Tuesday are forecast to remain sunny and brutally hot, with highs near 106 degrees Saturday and next Sunday and about 105 degrees next Monday and Tuesday. Overnight lows will offer little recovery, staying mostly between 81 and 83 degrees.

Wednesday may dip slightly to around 103 degrees, but the broader pattern remains firmly in triple digits. Forecasters also warn that low humidity and occasional lightning could increase grass-fire starts through the weekend, adding another reason to avoid careless outdoor burning.

Heat Safety Takes Priority

Limit strenuous outdoor activity during the hottest part of the day and move indoors or into shade whenever possible. Lightweight clothing, frequent water breaks, and regular rest periods can help reduce the risk of heat exhaustion.

Never leave children or pets in a parked vehicle, even briefly. Anyone showing signs of heat stroke should be moved to a cool place and treated as a 911 emergency.
