KEY MESSAGES

Issued at 120 PM CDT Wed Sep 23 2026

- Low chance for showers and thunderstorms across the southern half of the area Thursday.

- Above-normal temperatures persist through the forecast period.

DISCUSSION

Issued at 120 PM 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 again on Thursday, mainly across the southern half of the CWA. We may see a little better shot at some sea breeze showers and storms later this weekend into early next week as the high shifts southwest with a slight increase in mid-level lift overspreading the region.

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

(18Z TAFS) Issued at 120 PM CDT Wed Sep 23 2026 VFR conditions are expected to prevail through the TAF cycle. Winds will generally be 10-20 knots during the day and less than 10 knots at night. Scattered to broken CU will dissipate with the loss of daytime heating.

MARINE

Issued at 120 PM 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.
