TEXAS AND OKLAHOMA — Dangerously high heat index values ranging from 100 to 108 degrees are expected across much of the South tomorrow, with Texas and Oklahoma among the hardest-hit areas. Model data shows the most intense heat concentrated across central and eastern Texas, with widespread triple-digit heat index readings extending into surrounding states as well. Forecasters are urging residents across the region to take the heat seriously and prepare accordingly.
Central and Eastern Texas See the Most Extreme Readings
The highest heat index values are expected to concentrate across central and eastern Texas, where forecast data shows widespread readings between 100 and 108 degrees. Some localized spots could see even higher apparent temperatures depending on humidity levels and cloud cover throughout the afternoon hours.
Communities across this stretch of the state should expect little relief from the heat even after sunset, as overnight lows are likely to remain elevated compared to typical late-summer conditions in the region.
Oklahoma and Surrounding States Also Face Significant Heat Risk
Oklahoma is also forecast to see substantial heat index values in the 90s to low 100s, with some areas along the state’s southern border approaching the triple-digit readings seen farther south in Texas. The combination of high humidity and strong afternoon heating is driving the elevated apparent temperatures across the broader region.
Surrounding states, including portions of Louisiana, Arkansas, and the wider Gulf Coast, are also expected to see meaningfully elevated heat index values, though generally not reaching the extreme levels forecast for the Texas core…
