KEY MESSAGES

Issued at 641 AM CDT Wed Sep 23 2026

- Low daily chances for showers and thunderstorms continue, mainly across the Coastal Plains.

- Above-normal temperatures persist through the forecast period.

DISCUSSION

Issued at 132 AM CDT Wed Sep 23 2026

Little change in the overall pattern expected through much of the forecast period as South Texas remains under the influence of mid- level ridging. Sufficient moisture will remain in place for isolated showers and thunderstorms to develop along the sea breeze each afternoon, primarily across the Coastal Plains. Activity may occasionally push farther inland, through most locations will remain dry. Rain chances will generally remain low (20-25%) through the weekend and into next week.

Above-normal temperatures will continue through the period, with hot afternoons and warm overnight lows expected. Heat index values will generally remain below 110 degrees, though locally higher values cannot be ruled out. Continue to practice heat safety when spending time outdoors.

Forecast uncertainty begins to increase toward the middle of next week as guidance hints at a possible disturbance approaching the region. Confidence remains too low at this time regarding its evolution and potential impacts to South Texas.

AVIATION

(12Z TAFS) Issued at 641 AM CDT Wed Sep 23 2026

Some patchy fog has developed at the VCT terminal. This is expected to be very brief and should mixed by midmorning (15Z). VFR conditions are expected to prevail through the TAF cycle. Winds will be relatively light overnight across the region, though winds will increase around 15-20 knots during the afternoon. They will subside this evening becoming light and variable.

MARINE

Issued at 132 AM CDT Wed Sep 23 2026

A gentle to moderate (BF 3-4) east to southeasterly flow is expected to persist throughout the forecast period with seas between 2-3 feet. Low rain chances continue daily into next week.

FIRE WEATHER

Issued at 132 AM CDT Wed Sep 23 2026

Humidity levels remain elevated with minimum RH values staying above 35% for counties out west and winds are expected to remain light. Thus elevated fire weather conditions are not expected at this time.
