SHORT TERM

(Tonight through Saturday night) Issued at 100 PM CST Fri Feb 13 2026

An upper level trough extends from the Great Basin to southern CA and a ridge extends from TX to the northern Great Plains. A stationary front is stretched across TX from Beaumont to the Dallas/Fort Worth area to near Amarillo. Our CWA is in the warm sector with southeasterly winds. The airmass is warm and moist with temperatures in the 60s and 70s and dewpoints in the 50s and 60s. The upper trough will move across northern Mexico/AZ/NM tonight bringing southwesterly flow over TX. At the same time an area of low pressure will develop along the stationary front bringing through west TX as a cold front. Showers and thunderstorms will develop along the front. Some of these could move into our northwestern counties late this evening and spread to the south and east overnight. These features will continue to move to the east Saturday. As these systems move into the warm, moist airmass instability will be moderate, but vertical wind shear will be 40-50 kts. These conditions may generate some strong to severe storms with large hail and damaging winds the most likely threats. SPC has issued a level 1 of 5 (Marginal) risk for severe storms for western Val Verde County tonight and nearly all of South-Central Texas for Saturday. The best timing for strong storms will during the afternoon as the front moves through. The front should be to our eastern border by early evening and drier air will move in with northerly to northwesterly winds Saturday night.

LONG TERM

(Sunday through next Friday) Issued at 100 PM CST Fri Feb 13 2026

An upper ridge will build over the region Sunday and dominate the first part of next week. The weather will be dry through the long term period. The forecast problem will be the temperatures. Behind the front lows Monday will be within a few degrees of normal, but that will be the last time for this forecast period. Highs Monday will climb to well above normal and then continue higher into the middle part of the week. Records are surprisingly high for these days and the forecast mid-80s are not close. Still, it will be unusually warm.

AVIATION

(18Z TAFS) Issued at 100 PM CST Fri Feb 13 2026

The period begins with MVFR ceilings along portions of the Rio Grande, including KDRT. These conditions improve to VFR levels by around 20Z. Elsewhere, VFR conditions with sct to bkn mid-level clouds will trend through the afternoon and evening. An isolated shower or storm may enter Val Verde County this evening but is expected to quickly diminish with little to no impact to the terminal at KDRT. From the overnight through Saturday morning, anticipate for MVFR to IFR ceilings to establish across the area. Additionally, there should be a steady uptick in the chances for some light rain showers across the I-35 terminals from Saturday morning into the afternoon. A broken line of storms then could approach the 30 hr TAF sites (KAUS and KSAT) near the end of the period. Added PROB30 for -TSRA for this segment. VFR conditions should also return to the 30 hr TAF sites for Saturday afternoon. Winds will be steady out of the south-southeast with winds that are gusty into the 20 to 25 kt range at times.

FIRE WEATHER

Issued at 100 PM CST Fri Feb 13 2026

Dry and breezy winds behind the front will move into the northwest Saturday afternoon and spread to much of the area Sunday. This will lead to elevated to near critical fire weather conditions possible for the area generally west of I-10 (north of San Antonio) and I-37. Drier air is forecast to remain in place for much of next week, so additional elevated fire weather days could be possible.
