AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
113 AM CDT FRI SEP 12 2025
KEY MESSAGES
- TEMPERATURE REMAIN AT OR JUST ABOVE NORMAL THROUGH THE
FORECAST PERIOD.
SHORT TERM (THROUGH SATURDAY)
THE MID AND UPPER LEVEL SUBTROPICAL HIGH FROM NORTHERN MEXICO
INTO THE SOUTHERN U.S. PLAINS WILL REMAIN IN PLACE THROUGH THE
UPCOMING WEEKEND. THIS WILL RESULT IN A CONTINUATION OF
TEMPERATURES REMAINING AT OR ABOVE NORMAL ALONG WITH MOSTLY DRY
WEATHER FOR SOUTH CENTRAL TEXAS. THE EXCEPTION WILL BE ACROSS
PORTIONS OF THE COASTAL PLAINS WESTWARD TO THE RIO GRANDE WHERE
SOME ISOLATED CONVECTION MAY DEVELOP TODAY AND AGAIN ON
SATURDAY.
LONG TERM (SATURDAY NIGHT THROUGH THURSDAY)
AS WE HEAD INTO EARLY NEXT WEEK, THE MEDIUM RANGE MODELS SHOW AN
UPPER LEVEL TROUGH AXIS MOVING THROUGH THE SOUTHERN ROCKIES INTO
THE CENTRAL PLAINS STATES. THIS MAY SERVE TO TEMPORARILY WEAKEN
THE SUBTROPICAL RIDGE AXIS OVER THE SOUTHERN PLAINS. HOWEVER, WE
DON'T EXPECT TO SEE ANY SIGNIFICANT CHANGE IN OUR SENSIBLE WEATHER
THROUGH THE REMAINDER OF THE FORECAST PERIOD. LITTLE SPREAD IS
NOTED AMONG THE OPERATIONAL AND ENSEMBLE GUIDANCE WITH RESPECT
TO TEMPERATURES. HIGHS WILL GENERALLY RANGE FROM THE MID 80S TO
THE MID 90S ALONG WITH LOWS IN THE MID 60S TO LOWER 70S. ANY
OPPORTUNITIES FOR RAIN WILL REMAIN SCARCE AND PRIMARILY CONFINED
TO THE COASTAL PLAINS WESTWARD TO NEAR THE RIO GRANDE WHERE
MOISTURE LEVELS MAY BE SUFFICIENT TO SUPPORT SOME ISOLATED
CONVECTION.
AVIATION (06Z FRIDAY THROUGH SATURDAY)
MVFR CEILINGS ARE POSSIBLE YET AGAIN OVERNIGHT INTO THE MID-MORNING
HOURS FRIDAY, PARTICULARLY AT SAT, SSF, AND DRT. DRT STANDS THE BEST
CHANCE AT MVFR CEILINGS WITH PREVAILING GROUP UTILIZED BETWEEN
12- 15Z. TEMPO GROUPS WERE CONSIDERED AT SAT AND SSF BUT HELD
OFF FOR NOW AND WILL REEVALUATE AT THE 09Z AMENDMENTS.
OTHERWISE, VFR CEILINGS ARE EXPECTED THROUGH THE PERIOD ALONG
WITH INCREASING WINDS OF 9-12 KTS.
