AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
903 AM CST SUN JAN 11 2026
..NEW UPDATE
KEY MESSAGES
- A FREEZE IS LIKELY FOR MOST OF THE HILL COUNTRY, SOUTHERN EDWARDS
PLATEAU AND INTO THE RIO GRANDE PLAINS SUNDAY MORNING.
- WIDESPREAD CLOUDS AND COOLER TEMPERATURES MONDAY AND TUESDAY ALONG
WITH A LOW CHANCE FOR RAIN FOR MOST AREAS.
- TEMPERATURES TREND BACK TO ABOVE NORMAL MID TO LATE WEEK, WITH
COOLER TEMPERATURES TOWARD THE END OF THE FORECAST PERIOD.
UPDATE
ISSUED AT 858 AM CST SUN JAN 11 2026
THE FREEZE WARNING FOR VAL VERDE AND KINNEY COUNTIES WAS ALLOWED
TO EXPIRE AT 9 AM CST. TEMPERATURES ARE ABOVE THE FREEZING MARK
AND FORECAST TO RISE INTO THE LOWER 60S ACROSS THESE AREAS BY THE
AFTERNOON.
SHORT TERM
(TODAY THROUGH MONDAY)
ISSUED AT 1204 AM CST SUN JAN 11 2026
OBSERVATIONS SHOW PLENTY OF DRY AIR IN PLACE WITH DEWPOINTS IN THE
SINGLE DIGITS AND TEENS ALONG AND WEST OF I-35, WITH 20S ELSEWHERE.
SURFACE HIGH PRESSURE BUILDING IN FROM THE NORTHWEST WILL RESULT IN
DECREASING WINDS EARLY THIS MORNING. WHILE WE DO EXPECT TO SEE SOME
HIGH CLOUDS CONTINUE ACROSS THE REGION, BREAKS IN THE CLOUDS SHOULD
STILL ALLOW FOR RADIATIONAL COOLING. FREEZING TEMPERATURES ARE STILL
EXPECTED OVER THE HILL COUNTRY, SOUTHERN EDWARDS PLATEAU AND INTO
THE RIO GRANDE PLAINS. THE FREEZE WARNING FOR VAL VERDE AND KINNEY
COUNTIES WILL CONTINUE AS THESE COUNTIES HAVE YET TO SEE A
WIDESPREAD FREEZE THIS SEASON. OTHERWISE, LOOK FOR HIGH LEVEL CLOUDS
TO GRADUALLY INCREASE TODAY ALONG WITH HIGHS IN THE MID 50S TO LOWER
60S. A FAIRLY SIMILAR WEATHER PATTERN IS IN STORE ON MONDAY AS AN
UPPER LOW CURRENTLY OVER THE CENTRAL PORTION OF THE BAJA PENINSULA
MOVES INTO NORTHERN MEXICO. A CONTINUED INCREASE IN MID AND HIGH
LEVEL MOISTURE ALONG WITH SOME WEAK LIFT MAY AID IN THE DEVELOPMENT
OF SOME LIGHT RAIN OVER THE RIO GRANDE PLAINS LATE MONDAY.
LONG TERM
(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 1204 AM CST SUN JAN 11 2026
THE ABOVE MENTIONED UPPER LOW CONTINUES TO APPROACH THE REGION
MONDAY NIGHT INTO TUESDAY AND WE SHOULD SEE ENOUGH MOISTURE AND LIFT
TO RESULT IN SOME LIGHT RAIN ACROSS MOST OF SOUTH CENTRAL TEXAS. THE
NBM POPS LOOK A LITTLE LOW AND ARE CONFINED TOO FAR WEST WHEN
COMPARED WITH MODEL QPF OUTPUT FROM THE LATEST OPERATIONAL ECMWF AND
GFS. WHILE WE DON'T EXPECT TO SEE ANY SIGNIFICANT RAINFALL AMOUNTS,
WILL INCREASE RAIN CHANCES ABOVE THE NBM OFFERING. RAIN CHANCES
SHOULD DECREASE FAIRLY QUICKLY LATE TUESDAY INTO WEDNESDAY AS THE
UPPER LOW OPENS INTO A TROUGH AND SHIFTS EAST OF THE REGION
WEDNESDAY. A DECREASE IN CLOUDS WILL ALLOW FOR A QUICK WARMUP FOR
MOST AREAS ON WEDNESDAY WITH HIGHS TRENDING UPWARD INTO THE UPPER
60S AND LOWER 70S. WE DO EXPECT TO SEE A PACIFIC COLD FRONT MOVE
THROUGH THE REGION WEDNESDAY AFTERNOON, SO MAY HAVE TO WATCH FUTURE
MODEL RUNS FOR SLIGHTLY COOLER TEMPERATURES IN THE HILL COUNTRY AND
SOUTHERN EDWARDS PLATEAU THAN CURRENTLY FORECAST.
SURFACE HIGH PRESSURE BEHIND THE WEDNESDAY COLD FRONT DOES NOT
LINGER TOO LONG AS A SURFACE LOW DEVELOPS OVER NORTHEAST NEW MEXICO.
SOUTHERLY LOW-LEVEL WINDS KEEP TEMPERATURES ABOVE NORMAL ON FRIDAY,
BUT ANOTHER COLD FRONT MOVING IN LATE FRIDAY OR EARLY SATURDAY DROPS
TEMPERATURES BACK BELOW NORMAL ON SATURDAY. GIVEN THE LARGE SCALE
PATTERN AND CONSISTENT RUNS FROM THE ECMWF AI MODEL, WILL LIKELY
TREND TEMPERATURES LOWER THAN THE NBM TOWARD THE END OF CURRENT
FORECAST PERIOD.
