KEY MESSAGES

Issued at 616 AM CDT Thu Sep 24 2026

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

- Above-normal temperatures persist through the forecast period.

DISCUSSION

Issued at 1210 AM CDT Thu Sep 24 2026

Minimal change is expected in the overall pattern through the next several days as a mid-level ridge continues to influence the South Texas region. Adequate moisture in the area combined with daytime heating, will allow for up to a 50-65% chance for isolated to scattered showers and thunderstorms Thursday afternoon primarily across the southern Brush Country. Otherwise, mainly dry conditions are expected through the weekend, with only a low chance for isolated showers into early next week associated with the sea breeze.

Above-normal temperatures will continue through the period across the region. Afternoon heat index values will generally range between 100-109 degrees, while overnight lows remain quite warm in the mid to high 70's. These conditions will prevail through the weekend and into early next week.

Glancing ahead to the middle of next week, guidance continues to indicate the potential for a possible disturbance to approach or move across the area. However, notable differences remain among the models regarding its evolution, timing, and potential impacts. Given the continued uncertainty this far out, will refrain from making any significant changes to the forecast until better agreement emerges.
