SHORT TERM

(Today through Wednesday) Issued at 1230 AM CDT Tue Oct 13 2026

A deep upper level trough has moved onto the west coast and turned the flow over TX to the southwest. The low level flow continues to be from the southeast bringing a warmer, more humid airmass to South-Central Texas. Temperatures this evening are around five degrees warmer than 24 hours ago, and dewpoints are 5-10 degrees warmer. The upper trough will push toward the Four Corners region today and Wednesday. The low level flow will continue to be from the southeast. The deepening moist air combined with slight height falls will lead to chances for showers or thunderstorms each afternoon today and Wednesday. The best chances will be over eastern areas where moisture will be most plentiful. Temperatures will continue to be above normal both days. The higher humidity will result in heat indices 100-105 degrees for much of the CWA.

LONG TERM

(Wednesday night through Monday) Issued at 1230 AM CDT Tue Oct 13 2026

Models move the upper trough across the central Rockies and into the Plains bringing a cold front through South-Central Texas Thursday night into Friday. The best combination lift and moisture is looking like the Rio Grande region. There will be the possibility of locally heavy rain out there Thursday night/Friday. Rain chances have decreased over the eastern half of the area, and it is now looking like a dry forecast. Behind the front temperatures will be lower Friday through Sunday. Low temperatures next weekend could be in the 50s and highs in the 70s for most of the area. The low level flow will switch back around to the southeast by next Monday starting another warming trend.

AVIATION

(12Z TAFS) Issued at 539 AM CDT Tue Oct 13 2026

MVFR ceilings have established across the region with latest satellite imagery indicating some mid-level clouds above the low cloud bases. The MVFR ceilings persist into the mid to late morning before the low clouds scatter out and rise to VFR levels. Any isolated shower activity this afternoon should remain to the east in the coastal plains, not impacting the I-35 TAF sites. Conditions will remain VFR through at least this evening before MVFR ceilings will return with more low cloud cover by around or just after midnight. Winds otherwise remain moderate to breezy at times out of the south-southeast, and more out of the east- southeast for locations that are closer to the Rio Grande. Gusts are to peak into the 20 to 25 kt range from the afternoon through the evening while the lightest conditions will occur overnight into early each morning.
