KEY MESSAGES

Updated at 1236 PM CDT Sun Oct 18 2026

- One more cooler night before warmer temperatures return.

- No rain is expected at least through Saturday.

SHORT TERM

(Tonight through Monday night) Issued at 1236 PM CDT Sun Oct 18 2026

Our temperatures are on the way up to reach the upper 60s to mid 70s area-wide after a cool start in the upper 30s to near 50 earlier this morning. Latest IR and water vapor satellite images are showing scattered to broken high clouds pushing mainly across the southern portion of the Rio Grande. This trend continues through the afternoon, evening, and into Monday morning. At the surface, light northeast to east wind flow dominates areas along and east of Highway 281 while areas across the southern Edwards Plateau and Rio Grande Plains likely to remain under a southeast wind flow for the rest of this afternoon into Monday. Later this evening continuing through Monday morning, a southeast wind flow takes over the local area as an elongated surface ridge extends southwestward from the middle Atlantic states. This pattern allows overnight lows to stay cool but warmer than this morning, ranging from the upper 40s to upper 50s. As the day progresses, increased low level moisture could end up developing some low level clouds in addition to the high clouds pushing from northeast Mexico. Monday's highs are forecast to range from the mid to upper 70s and low to mid 80s across portions of the Coastal Plains and the Rio Grande. Clouds increase Monday evening into Tuesday morning for partly cloudy to cloudy skies over a good portion of the local area through the period. Forecast lows to reach the mid 50s to mid 60s which make these values closer and even a bit higher than climate normals for this time.

LONG TERM

(Tuesday through next Sunday) Issued at 1236 PM CDT Sun Oct 18 2026

Upper level ridging is forecast to dominate the local area throughout the work week while increased moisture continues to be pulled from the Gulf into South Central Texas. This translates into warm to warmer weather returning with highs in the 80s over most locations on Tuesday to mid 80 to lower 90s by Friday. The local area remains rain-free through this period.

By next weekend, the upper level ridging shifts to the east of the local area and allows upper level shortwave disturbances to ride along the southwest to northeast flow aloft. This could bring low chances for rain across portions of the southern Edwards Plateau and Rio Grande especially Sunday. The eastern two-thirds of the local area to remain dry.

AVIATION

(18Z TAFS) Issued at 1236 PM CDT Sun Oct 18 2026
