DISCUSSION

Issued at 122 AM CDT Fri Aug 21 2026

BLUF: It is still hot. It is still dry. It will continue to be this way at least through next week.

High pressure remains in control, keeping temperatures above normal, with highs in the 90s along the coast, rapidly increasing to over 100 degrees as we move inland toward the Brush Country where max temperatures will near 106. Heat index values today will range from 105-114. The highest values will be along the inland Coastal Bend and Coastal Plains due to higher moisture in the area. A Heat Advisory is in effect for today from noon to 8 PM. Expect we will need more Heat Advisories through the weekend. Take frequent breaks and remember to stay hydrated, check your backseat, and avoid long exposure in these temperatures. For more information be sure to check out weather.gov/heatsafety.

High pressure will also serve to limit any significant chances for precipitation, though there is a very low (<10%) chance of seabreeze convection in the afternoons.
