DISCUSSION

Issued at 131 PM CDT Tue Jul 28 2026

Hot and mostly dry conditions will continue through the weekend thanks to a mid-level high to our northwest. High temperatures will range from the mid 90s along the coast to around 105 over the Brush Country. Heat index values are expected to be slightly lower for Wednesday, but there could still be some locations that reach advisory criteria, mainly over the southern Coastal Plains. For now, will not issue a Heat Advisory, but expect this could be done on the next forecast update. As we move later into the week, the HeatRisk will remain in the moderate to major categories, with isolated locations reaching an extreme HeatRisk. As these higher temperatures and moisture occur, we will likely have Heat Advisories for later this week.

The interesting news is that there could be some slightly different weather early next week as a mid-level trough stretches along the eastern periphery of the ridge, nearing the Victoria Crossroads. This could introduce enough lift and moisture for a low chance of showers and thunderstorms (15-20%). Temperatures will, however, continue to be hot.

AVIATION

(18Z TAFS) Issued at 131 PM CDT Tue Jul 28 2026

VFR conditions continue this afternoon, even with some cloud cover over and along the coast. By late tonight/early morning, MVFR ceilings will develop, mostly for ALI and VCT though COT may join the party. Winds will diminish overnight which, when combined with the increased moisture, could lead to some patchy fog development for VCT and ALI. Have included a TEMPO group for the MVFR ceilings and visibility from 09Z-13Z.

MARINE

Issued at 131 PM CDT Tue Jul 28 2026

A generally gentle to moderate (BF 3-4) onshore flow will persist, with moderate to fresh (BF 4-5) conditions during the evening and overnight hours. Small Craft Advisories may be needed in the late afternoon and evening hours. Seas will remain around 2-4 feet. Dry conditions are expected through the forecast period, with probabilities for rain near zero.
