KEY MESSAGES

Issued at 1230 PM CDT Mon Aug 17 2026

- Moderate to major risk of heat-related impacts through next week with peak afternoon heat indices around 110

- Monitoring daily elevated fire weather potential over the Brush Country through Sunday

DISCUSSION

Issued at 1230 PM CDT Mon Aug 17 2026

Not much change in the forecast through this upcoming weekend. The mid-level ridge stretched across the southern CONUS will amplify and center over the Four Corners region late this week, while an upper level trough from the Great Lakes region deepens and moves into the eastern CONUS. This feature still doesn't make much of an impact over South Texas, keeping any potential increased rain chances off to our northeast. Thereafter, the aforementioned amplified ridge will take control over the central CONUS setting up a high latitude Omega pattern and continue hot and rain-free conditions into the middle of next week.

Hot and rain-free conditions, with the exception of a few seabreeze showers inland, will persist through this upcoming weekend. Max temperatures will continue to range from around 90 along the coast to around 105 over the Brush Country, with daily peak heat indices flirting around 110. All are urged to practice heat safety! UIL WBGT risks will range from moderate to high, with greatest risk Thursday and Friday. The Brush Country will continue to borderline elevated fire weather conditions each afternoon and early evening as relative humidity reaches its minimum below 30% and winds gust around 20 mph.

AVIATION

VFR conditions prevail across South Texas early this afternoon. Southeasterly winds of 10-15 knots with gusts around 20 knots will weaken to near calm overnight into the early morning hours on Tuesday. The calm winds and mostly clear skies tonight will promote similar conditions as of this morning, leading to MVFR prevailing conditions for ALI/VCT and potential LIFR vsby and ceilings mainly between 09-13Z. Brief MVFR conditions can be expected for CRP as well. VFR conditions prevail by 16Z across all terminals.
