SHORT TERM
(TODAY THROUGH FRIDAY NIGHT)
ISSUED AT 541 AM CST WED DEC 31 2025
CURRENTLY THE HIGH PRESSURE IS CENTERED OVER TX/LA WITH LIGHT AND
VARIABLE TO CALM WINDS ACROSS THE CWA. SKIES ARE CLEAR, ALLOWING
FOR EFFECTIVE RADIATIONAL COOLING. AS OF 12 AM, TEMPERATURES ARE
IN THE UPPER 20S TO UPPER 30S, AND WE COULD SEE TEMPERATURES DROP
INTO THE MID 20S ACROSS PARTS OF CENLA AND INTERIOR SETX. A LIGHT
FREEZE, ALONG WITH AREAS OF FROST, WILL BE POSSIBLE FOR A MAJORITY
OF THE FORECAST AREA, WITH EXCEPTION TO THE COASTLINE.
BY WEDNESDAY, THE SURFACE HIGH WILL SINK FURTHER SOUTH INTO THE
GULF, ALLOWING WINDS TO BECOME SOUTHWESTERLY TO SOUTHERLY, WITH
INCREASING MOISTURE AND A WARMING TREND ENSUING. WEDNESDAY’S HIGHS
WILL REACH THE 60S, THURSDAY’S HIGHS WILL CLIMB INTO THE UPPER 60S
TO LOWER 70S, AND FRIDAY’S HIGHS WILL RANGE FROM THE MID 70S TO
LOWER 80S. OTHER THAN WARMING TEMPERATURES AND INCREASINGLY HUMID
CONDITIONS, BREEZY CONDITIONS ARE POSSIBLE ON FRIDAY AS A
TIGHTENED PRESSURE GRADIENT DEVELOPS BETWEEN THE DEPARTING SURFACE
HIGH AND AN INCOMING SYSTEM. SUSTAINED WINDS COULD EXCEED 20 MPH,
AND A WIND ADVISORY MAY BE NEEDED. HOWEVER, GIVEN THE TIME RANGE,
THIS WILL BEAR WATCHING.

(SATURDAY THROUGH WEDNESDAY)
ISSUED AT 541 AM CST WED DEC 31 2025
DURING THE WEEKEND, A WEAK COLD FRONT IS EXPECTED TO MOVE THROUGH
THE AREA. ISOLATED SHOWERS ARE NOT OUT OF THE REALM OF
POSSIBILITY; HOWEVER, MOISTURE RETURN AHEAD OF THE FRONT WILL BE
LIMITED. A BRIEF DROP IN TEMPERATURES IS EXPECTED, WITH VALUES
REBOUNDING QUICKLY AS ONSHORE FLOW RESUMES AND RIDGING BUILDS
ALOFT. WITH THE EXCEPTION OF SLIGHTLY COOLER TEMPERATURES
