KEY MESSAGES

- Warm and humid Monday.

- Chances for showers and thunderstorms return Tuesday through Saturday.

SHORT TERM

(Tonight through Monday night) Issued at 121 PM CDT Sun May 31 2026

A low amplitude upper level ridge extends from the Gulf to the Great Lakes with flow from the west-southwest over TX. Low level flow is from the southeast. The airmass over South-Central Texas remains warm and moist. Temperatures across our CWA were in the low to mid 80s and dewpoints from the upper 60s to the mid 70s. The upper pattern will remain about the same through the short term period. This should suppress any convection and keep the weather dry. The airmass will remain warm and moist. Overnight lows tonight and tomorrow night will be mostly in the 70s. Highs on Monday will be from the upper 80s to middle 90s.

LONG TERM

(Tuesday through next Sunday) Issued at 121 PM CDT Sun May 31 2026

Tuesday the ridge will begin to break down. Deeper moisture will surge into the region increasing PW values. The increased moisture and the weakening subsidence will allow showers and thunderstorms to form during the afternoon and evening starting Tuesday and then each afternoon and evening through Saturday. This pattern is looking very summer-like. It should be ordinary convection with only moderate rainfall and wind gusts. Thursday and Friday look to have the best chances for convection.

AVIATION

(18Z TAFS) Issued at 1237 PM CDT Sun May 31 2026

Mix of MVFR/VFR CIGs out there today across the I-35 TAF sites. Decided to add TEMPOs in for the next couple hours as a cloud deck continues to move over the area thins out a bit and hopefully pushes off to the east. VFR cigs should return once that occurs. MVFR CIGs come back overnight and continue into Monday morning for all TAF sites with IFR CIGs possible for a couple hours for KSAT and KSSF. KAUS may get as low as IFR but confidence is low so no mention just yet in the package. VFR CIGs should resume by early tomorrow afternoon for all. South to southeast winds of 5 to 10 knots are forecast to prevail through the entirety of the forecast period with the exception of KDRT where we could see 10 to 15 knots with occasional gust up to 25 knots.
