Beat the Heat

Another hot and humid day with elevated heat index values is expected across our area. High temperatures will range from the mid 90s in the Hill Country to the lower 100s across the Rio Grande Plains. Heat index values of 104 to 108 are expected south and east of the Escarpment with isolated spots reaching near 110. Scattered showers and thunderstorms are expected near the Coastal Plains becoming more isolated toward the I-35 corridor.

Aside from isolated showers and thunderstorms early this evening mainly south and west of San Antonio, tonight will be warm with partly cloudy skies. Lows will be in the 70s with south- southeast winds at 5-15 mph with a few gusts to 20 mph within a few hours of sunset this evening.

Above normal temperatures and humid conditions will continue through the weekend, then drop a little early next week as an unseasonable late July "cold" front moves into our area. Afternoon heat index values of 104 to 108 south and east of the Escarpment are expected Thursday through Sunday with isolated spots reaching near 110. Isolated afternoon and early evening showers and thunderstorms are possible near the Coastal Plains on Thursday afternoon along the sea-breeze. The "cold" front will bring isolated to scattered showers and thunderstorms beginning on Saturday into Monday. Please take frequent breaks and drink plenty of water while working outside.
