SHORT TERM
(TONIGHT THROUGH MONDAY NIGHT)
ISSUED AT 1230 PM CDT SUN OCT 26 2025
THIS MORNING'S FOG THAT HAD DEVELOPED WITHIN SOME OF THE LOCAL
RIVER VALLEYS, PORTIONS OF THE AUSTIN METRO AREA, AND FOR AREAS
FROM FAYETTE COUNTY AND NORTH-NORTHEASTWARD HAS IMPROVED LATE THIS
MORNING WITH ANY REMAINING LOW STRATUS ERODING TOWARDS MOSTLY
SUNNY SKIES. LATE TONIGHT INTO MONDAY MORNING COULD ALSO SEE THE
DEVELOPMENT FOR SOME FOG ALONG AND EAST OF THE I-35 CORRIDOR.
OTHERWISE, FAIR WEATHER TRENDS THROUGH THE SHORT TERM WITH A DRY
WEST-NORTHWESTERLY FLOW ALOFT IN WAKE OF THE UPPER LEVEL SYSTEM
THAT HAD BROUGHT THE RECENT RAINS. WINDS REMAIN LIGHT THROUGH
MONDAY BUT A SLIGHT UPTICK IN LOW-LEVEL FLOW FOR MONDAY NIGHT LOOK
TO RESULT IN SLIGHTLY HIGHER DEW POINTS AND A SLIGHTLY MILDER
NIGHT COMPARED TO TONIGHT'S EXPECTED OVERNIGHT LOWS. THE DAYTIME
HIGHS ACROSS THE REGION WILL REACH INTO THE 80S AND 90S BUT MONDAY
WILL BE THE WARMEST DAY AS HIGHS WILL BY ABOUT 3 TO 5 DEGREES
HIGHER AREA WIDE IN COMPARISON TO THIS AFTERNOON.
LONG TERM
(TUESDAY THROUGH NEXT SUNDAY)
ISSUED AT 1230 PM CDT SUN OCT 26 2025
A DEEPENING UPPER LEVEL LOW THAT WILL DIG SOUTH-SOUTHEASTWARD
FROM THE NORTHERN PLAINS INTO THE LOWER MISSISSIPPI VALLEY WILL
HELP TO BRING THE STRONGEST FRONT OF THE SEASON SO FAR ACROSS
SOUTH-CENTRAL TEXAS ON TUESDAY. COLD AIR ADVECTION IN WAKE OF THE
FRONTAL PASSAGE, LEADS TO OUR FIRST TRUE TASTE OF FALL WEATHER
THROUGHOUT OUR REGION AS SOON AS TUESDAY NIGHT. WHILE, THERE IS A
SUBTLE WARMING TREND WITH THE RETURNING SOUTHERLY LOW-LEVEL FLOW
BY LATE WEEK INTO NEXT WEEKEND, ANTICIPATE FOR AT LEAST NEAR TO
BELOW AVERAGE TEMPERATURES TO CONTINUE INTO EARLY NOVEMBER. LOW-
LYING SPOTS WITHIN THE HILL COUNTRY AND ALONG THE ESCARPMENT
COULD SEE THE SUNRISE TEMPERATURES IN THE 30S, ESPECIALLY
THURSDAY. A DRY NORTHWESTERLY FLOW ALOFT KEEPS RAIN OUT OF THE
FORECAST. THE ONLY EXCEPTION BEING, A SLIGHT CHANCE OF SHOWERS OR
A STORM ALONG THE FRONT TUESDAY AFTERNOON, MAINLY FOR LOCATIONS
ALONG THE HIGHWAY 77 CORRIDOR IN THE COASTAL PLAINS.
AVIATION
(00Z TAFS)
ISSUED AT 659 PM CDT SUN OCT 26 2025
VFR AND LIGHT VARIABLE WINDS PREVAIL ACROSS THE REGION. HOWEVER,
LOW CIGS AND VSBYS ARE EXPECTED TO DEVELOP MAINLY AFTER 09Z NEAR
AND GENERALLY EAST OF A LINE FROM KGTU TO KAUS TO KSAT. THE
WESTERN EXTENT OF THE IFR TO LIFR CONDITIONS IS UNCERTAIN AND
TERMINAL-SPECIFIC GUIDANCE HAS REPEATEDLY VARIED IN TIMING AND
OCCURRENCE OF IMPACTS AT KAUS/KSAT/KSSF. HAVE INTRODUCED
PREVAILING LOW SCT BASES AT THOSE THREE SITES AT 09Z THROUGH
16Z-18Z TO INDICATE POTENTIAL CIG DEVELOPMENT AND MAINTAINED
TEMPOS FOR REDUCED VSBYS WHERE CONFIDENCE IS HIGHER AT KAUS AND
KSSF. HOWEVER, WILL NEED TO ASSESS WHERE LOW CLOUDS AND BR/FG
DEVELOPMENT LATER TONIGHT FOR CLEARER DELINEATION OF IMPACTS. KDRT
WILL LIKELY STAY WELL WEST OF THESE AVIATION IMPACTS. LIGHT WINDS
ARE EXPECTED TO PERSIST THROUGHOUT THE TAF PERIOD.
FIRE WEATHER
ISSUED AT 1230 PM CDT SUN OCT 26 2025
IN THE WAKE OF THE FRONTAL PASSAGE TUESDAY, MINIMUM HUMIDITIES IN
THE TEENS TO 20S ARE EXPECTED ON WEDNESDAY. NORTHERLY WINDS OF 10
TO 20 MPH WITH GUSTS TO 25 TO 30 MPH COULD RESULT IN ELEVATED TO
NEAR CRITICAL FIRE WEATHER CONDITIONS AS THE IMPACT OF OUR RECENT
WETTING RAINFALL BEGINS TO DECREASE. ALTHOUGH MINIMUM HUMIDITIES
WILL ONLY BE SLIGHTLY HIGHER ON THURSDAY, WINDS OF LESS THAN 10
MPH ARE EXPECTED.
