KEY MESSAGES
- Warm and humid Sunday and Monday.
- Chances for showers and thunderstorms return Tuesday through next Saturday.
SHORT TERM
(Today through Monday) Issued at 105 AM CDT Sun May 31 2026
Weak mid-level ridging remains in place today, but with surface flow out of the south, expect continued warm and humid conditions, particularly given recent rainfall leading to increased soil moisture and enhanced dewpoints. The forecast remains dry today and tomorrow with highs topping out in the upper 80s to upper 90s. Mornings will start out muggy, generally in the lower to middle 70s along with some patchy morning fog over the Coastal Plains. Heat indices should be rather tame despite the higher dewpoints, as afternoon sunshine should be a bit more prevalent today and tomorrow, leading to more drying of the boundary layer into the afternoon hours each day.
LONG TERM
(Monday night through Saturday) Issued at 105 AM CDT Sun May 31 2026
Tuesday and beyond looks to turn more active as southwesterly mid- level flow ramps up in response to an approaching trough over the western CONUS. PWATs will start to ramp up to 1.5-1.9" through midweek, and with increased instability and lift in advance of the aforementioned trough, daily rain and storm chances are in the cards for South Central Texas. Locally heavy rainfall is possible at times, but widespread flooding concerns are low. Temperatures remain on the warmer end, but actually not particularly hot for early June.
AVIATION
(12Z TAFS) Issued at 526 AM CDT Sun May 31 2026
MVFR conditions are forecast to persist along the I-35 sites through 15Z. Then, VFR conditions take over through late tonight/overnight period. MVFR cigs come back overnight/Monday morning. Southeast winds of 5 to 10 knots are forecast to prevail through the forecast cycle.
