DISCUSSION

Issued at 230 PM CDT Wed Aug 19 2026

Beginning to sound like a broken record here, but it is going to be a very hot period through next week for South Texas. A high that is located around the Four Corners region, will meander south-southeastwards slightly over next week. This will promote very dry rain free conditions outside of occasional isolated seabreeze convection daily. Will continue to monitor the need for short-fused heat related products. We could see peak heat indices of 110 to 115 with dew points in the mid to upper 70s into next week. This translates to moderate to predominately major HeatRisk conditions, though some areas of extreme HeatRisk will be possible in the Brush Country. We strongly encourage the practice of heat safety in these conditions. Take frequent breaks and remember to stay hydrated, check those backseats, and avoid long exposure in these temperatures.
