SHORT TERM

ISSUED AT 1248 AM CDT WED OCT 8 2025
A WEAK COLD FRONT WILL MOVE INTO THE REGION TODAY, WITH DRIER AIR
FILTERING INTO THE HILL COUNTRY, I-35 CORRIDOR, AND INLAND
COASTAL PLAINS. HIGHER MOISTURE VALUES WILL REMAIN POOLED TODAY
FROM THE WESTERN HILL COUNTRY, SOUTHERN EDWARDS PLATEAU, AND RIO
GRANDE, SOUTHWARD INTO SOUTH TEXAS. HREF MEMBERS ARE CONSISTENT
WITH ISOLATED SHOWER DEVELOPMENT THROUGH THIS REGION THIS
AFTERNOON. THE DRIER AIR PUSHES FARTHER SOUTH, THROUGH THE AREA,
ON THURSDAY. WARM CONDITIONS CONTINUE, WITH HIGH TEMPERATURES IN
THE UPPER 80S TO MID 90S AND LOW TEMPERATURES IN THE MID 60S TO
LOW 70S.
LONG TERM
(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 1248 AM CDT WED OCT 8 2025
RIDGING ALOFT WILL REMAIN OVER THE REGION FRIDAY THROUGH THE
WEEKEND. IN THE LOWER LEVELS, EXPANDING HIGH PRESSURE TO THE
NORTHEAST ALLOWS EVEN DRIER AIR TO BACKDOOR INTO THE REGION, WITH
PRECIPITABLE WATER VALUES OF ONLY 0.7-1.1 INCHES INDICATED FRIDAY
AND SATURDAY. LOWER DEW POINTS AND MOSTLY CLEAR SKIES WILL ALLOW
FOR LARGE DIURNAL SWINGS IN TEMPERATURES FRIDAY THROUGH SUNDAY.
LOW TEMPERATURES SATURDAY ARE FORECAST TO DIP INTO THE 50S FOR
MANY AREAS, OUTSIDE OF THE URBAN SAN ANTONIO AND AUSTIN METRO
AREAS AND RIO GRANDE WHERE LOWS IN THE LOWER 60S ARE FORECAST.
HIGHS SATURDAY ARE FORECAST TO REBOUND TO A WARM UPPER 80S TO
LOWER 90S, BUT LOW RELATIVE HUMIDITY.
SOUTHERLY LOW LEVEL FLOW RESUMES SUNDAY, AND LOW LEVEL MOISTURE
IS FORECAST TO GRADUALLY INCREASE ESPECIALLY SUNDAY NIGHT INTO
MONDAY. THIS SHOULD RESULT IN INCREASING HUMIDITY AND SMALLER
DIURNAL WINGS IN TEMPERATURES MONDAY AND TUESDAY.
AVIATION
(06Z TAFS)
ISSUED AT 1248 AM CDT WED OCT 8 2025
VFR FLIGHT CONDITIONS ARE TO PREVAIL ACROSS THE TAF SITES THROUGH
THE PERIOD. A SURFACE BOUNDARY ACROSS THE REGION CONTINUES TO
HELP GENERATE A COUPLE BRIEF RAIN SHOWERS AT THE TIME OF THIS
DISCUSSION BUT THIS WILL LIKELY WANE WITHIN THE NEXT OR TWO.
CONFIDENCE IS TOO LOW FOR ANY SHOWER TO IMPACT THE TAF SITES FOR
INCLUSION OF VCSH OR SHRA OVERNIGHT. OTHERWISE, EXPECT FOR FEW TO
BKN MID-LEVEL CLOUDS ACROSS THE REGION WITH LOW CLOUDS FOCUSING
FARTHER SOUTH AND INTO PORTIONS OF THE RIO GRANDE PLAINS. ANY MVFR
CEILINGS SHOULD FOCUS SOUTH OF THE TERMINALS BUT A FEW LOW CLOUDS
MAY REACH DRT. DRT COULD SEE A SPOTTY SHOWER CHANCE IN THE
AFTERNOON AND IS ENOUGH TO INSERT VCSH WITHIN THE TAF. THE REST OF
THE SITES SHOULD REMAIN RAIN FREE. WINDS DURING THE AFTERNOON
THROUGH THE EARLY EVENING WILL TREND OUT OF THE NORTHEAST UP NEAR
10 KTS. LIGHT AND VARIABLE CONDITIONS OTHERWISE TREND OVERNIGHT
INTO THE MORNING.
