AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
645 AM CDT SUN SEP 14 2025
KEY MESSAGES
- ABOVE NORMAL AFTERNOON HIGHS CONTINUE THROUGH THE WEEKEND INTO
NEXT WEEK.
- LOW END CHANCES FOR SHOWERS AND STORMS ALONG THE RIO GRANDE
SUNDAY.
SHORT TERM (THROUGH MONDAY NIGHT)
A MID-LEVEL TROUGH OVER UTAH WILL SLIDE EAST SUNDAY, AND WITH
WEAK SOUTHWEST FLOW ALOFT OVER THE RIO GRANDE PLAINS, SOME
AFTERNOON SHOWERS AND STORMS MAY DEVELOP IN THE MID TO LATE
AFTERNOON HOURS, BUT HI-RES GUIDANCE IS NOT PARTICULARLY HIGH ON
COVERAGE TODAY, BUT ANY RAIN IS APPRECIATED OVER THE DRIER
SECTIONS OF THE RIO GRANDE PLAINS. TEMPERATURES WILL REMAIN NEAR
OR ABOVE SEASONAL NORMALS, WITH AFTERNOON HIGHS IN THE LOWER TO
MIDDLE 90S. LATE SUNDAY NIGHT INTO EARL MONDAY, MID-LEVEL
RIDGING WILL START TO WORK INTO THE REGION, DRYING THINGS BACK
OUT AND RESULTING IN AFTERNOON HIGHS AGAIN IN THE MID 90S.
LONG TERM (TUESDAY THROUGH SATURDAY)
RIDGING WILL STRENGTHEN OVER THE REGION ON TUESDAY, BUT QUICKLY
WEAKENS AND GETS SHOVED SOUTH AND WEST ON WEDNESDAY AS ANOTHER
TROUGH DIVES SOUTHEASTWARD INTO THE HIGH PLAINS STATES. WE MAY
GET SOME INCREASED CLOUDS AND LOW END RAIN CHANCES OUT OF THIS
SYSTEM, BUT IT LOOKS TO BE TOO FAR NORTH TO AFFECT OUR WEATHER
TOO MUCH. NEVERTHELESS, WILL CARRY LOW END POPS IN THE 20% RANGE
THURSDAY AND FRIDAY FOR THE POSSIBILITY OF PRECIPITATION IN THE
LONG TERM. OTHERWISE, WARM AND DRY CONDITIONS ARE EXPECTED
THROUGH THE LONG TERM FORECAST PERIOD.
AVIATION (12Z SUNDAY THROUGH MONDAY)
MVFR CIGS CONTINUE THROUGH LATE MORNING AT DRT, WITH SAT AND SSF
SEEING MORE IN THE WAY OF TEMPO MVFR THROUGH MID-MORNING. WE
WILL CONTINUE TO LEAVE THE FORECAST VFR AT AUS AS SOME DRIER AIR
IN THE LOWER LEVELS PERSISTS. WE WILL CONTINUE TO MONITOR THE
POSSIBILITY OF SOME CONVECTION APPROACHING DRT FROM THE WEST.
FOR NOW, WE WILL NOT MENTION IN THE FORECAST AT THIS TIME AS
MODELS GENERALLY KEEP CONVECTION ISOLATED RIGHT ALONG THE RIO
GRANDE.
