KEY MESSAGES

- Warmer temperatures to start 2026 with dry weather continuing.

- High temperatures likely to near or exceed daily records on Friday.

SHORT TERM

(Tonight through Friday night) Issued at 1139 PM CST Wed Dec 31 2025

Happy New Year! A crisp start to 2026 will be seen with morning lows in the upper 30s to low 40s across South Central Texas. Surface high pressure over the Gulf will keep low level southerly flow over the area in conjunction with upper level ridging. The result will be another day of warmer temperatures than previous days with highs mainly in the 70s areawide. A weak shortwave approaches our area in the afternoon and evening bringing increased mid and upper level cloud cover. Tonight, the cloud cover generally clears from west to east with lows in the 50s. With the highest moisture over the coastal plains early Friday morning, patchy fog could be seen.

Friday is going to be downright hot for January with widespread temperatures in the 80s and locations along the I-35 corridor, the Rio Grande and over the coastal plains in the mid or even upper 80s. Forecast temperatures are currently either at or above daily records at Austin and San Antonio sites. Clear skies and warm downsloping wind will lend its hand in the unseasonably warm day.

LONG TERM

(Saturday through next Thursday) Issued at 1139 PM CST Wed Dec 31 2025

A weak cold front finishes moving through the area Saturday morning, which will bring some relief to warm temperatures, though it's pretty minimal with highs for the weekend still roughly 10-15 degrees above normal for early January. Highs Saturday range from the 70s to low 80s with slightly "cooler" temperatures Sunday in the 70s areawide. Southerly flow returns under ridging aloft early next week bringing increased cloud cover and a warming trend back to the area. It does appear daily records could again be challenged next week.

AVIATION

(12Z TAFS) Issued at 504 AM CST Thu Jan 1 2026

VFR skies will continue at all sites through 18Z Friday. Thin high clouds will thicken up late in the day and could lower to below 20 KFt but be no threat to reaching into MVFR restrictions. More clearing of skies would then follow for Friday. Daytime winds of mainly 5-12 KTs will continue to be mainly a S or SW wind, but Friday's wind directions will be more erratic on direction as a weak front approaches.
