A stubborn late‑summer heat wave continues to dominate much of North Texas this Sunday, where a Heat Advisory remains in effect and heat index values are expected to climb toward 108 degrees. Morning sunshine and building humidity will set the stage for another hot afternoon, and while most areas remain dry, isolated storms may redevelop across Central Texas, carrying a modest chance of brief downpours.
Labor Day Monday offers little relief. Highs surge back into the upper 90s and near 100 degrees, with heat index values again pushing toward 108 degrees. Rain chances fall, leaving most communities under a dome of thick, late‑season heat.
The pattern doesn’t budge as the new week begins. A strong upper‑level ridge remains locked over the central U.S., ensuring above‑normal temperatures through mid‑month. Across North Texas, highs could reach 103 degrees, with heat index values continuing to flirt with 108 degrees. Dry weather prevails, and the region stays firmly planted in a prolonged stretch of summer‑like conditions.
Farther south, the Austin and San Antonio corridor sees highs ranging from the lower to upper 90s, with isolated to scattered showers and thunderstorms possible across the southern Edwards Plateau, Hill Country, and Coastal Plains. Southerly winds persist, and while rain chances remain low to moderate, temperatures stay above seasonal norms throughout the week.
Nationally, the weather story splits sharply. The Weather Prediction Center notes scattered strong to severe thunderstorms across the Southeast as cooler air pushes southward behind a deepening low over the Canadian Maritimes. This front brings a refreshing break to the eastern U.S., with highs dipping into the mid‑70s and low 80s, and morning lows dropping into the 40s and 50s across New England — a first hint of fall.
Meanwhile, the western U.S. braces for cool, unsettled weather as a deep upper‑level low moves inland. Heavy rain threatens parts of Utah today, and northwestern Montana faces a slight risk of excessive rainfall on Labor Day. As this system evolves, strong thunderstorms are expected to develop across the northern Plains into Tuesday.
Under the heat dome at the nation’s center, oppressive temperatures continue across the Central and Southern Plains and the Mississippi Valley. Heat indices of 105 to 110 degrees and unusually warm overnight lows will persist through Labor Day and into next week.
As Texans celebrate the holiday weekend, the message remains clear: limit afternoon outdoor activity when possible, stay hydrated, and take care of yourself and those around you as this relentless stretch of summer heat continues.
