SHORT TERM
(TODAY THROUGH SATURDAY NIGHT)
ISSUED AT 1146 AM CST THU DEC 25 2025
FOG, ALBEIT IT NOT AS DENSE, IS STILL TAKING ITS TIME TO
DISSIPATE THIS CHRISTMAS MORNING. VISIBILITIES ARE ALL NORTH OF 1
SM AT THIS TIME WITH LOW BROKEN TO OVERCAST SKIES. WHILE WE DID
NOT GET THE CHILLY AND "WHITE CHRISTMAS" ONE WOULD HAVE HOPED FOR,
THE CLOUD COVER IS ASSISTING IN KEEPING OUR TEMPERATURES IN THE
MID 60S TO 70S. WITH THE CLOUD COVER LIKELY TO ERODE IN SOME
AREAS, WE COULD POTENTIALLY SEE ANOTHER DAY OF RECORD SETTING
DAILY HIGH TEMPERATURES.
THE SURFACE HIGH PRESSURE REMAINS ATOP THE NE SIDE OF THE GULF
COAST REGION WITH A MID TO UPPER RIDGE CENTERED OVER MX. OVER THE
ENTIRETY OF THE SHORT TERM, LITTLE TO NO CHANGES ARE EXPECTED TO
EITHER, WITH SIMILAR WEATHER EXPECTED DAILY. WITH THAT SAID, WE
CAN EXPECT MORE DAYS (WELL EVENINGS TO MORNINGS) OF DENSE FOG AND
DAYS OF POSSIBLY ACHIEVING DAILY MAXIMUM TEMP RECORDS.
LONG TERM
(SUNDAY THROUGH THURSDAY)
ISSUED AT 1146 AM CST THU DEC 25 2025
OVER THE LONG TERM, THE UPPER RIDGE WILL FLATTEN AND BE SHIFTED
EASTWARD OVER THE GULF AS AN UPPER TROUGH APPROACHES. THIS WILL
SEND A COLD FRONT THROUGH OUR CWA SUNDAY INTO MONDAY. NOT MUCH IN
THE WAY OF STORMS WILL BE EXPECTED, HOWEVER ISOLATED TO SCATTERED
SHOWERS WILL SPREAD INTO THE AREA AHEAD OF AND ALONG THE FRONT.
ONCE THE FRONT CLEARS OUT, WE WILL SEE DRIER AND COOLER AIR RUSH
IN. THIS WILL ASSIST IN ENDING THE PERSISTENT FOGGY NIGHTS. WHILE
IT’S TOO EARLY TO SAY, A WIND ADVISORY COULD BECOME NECESSARY
ACROSS PARTS OF THE AREA AS SUSTAINED NORTHERLY FLOW IS EXPECTED
TO BE ELEVATED AND GUSTY. TEMPERATURES WILL SEE A SUBSTANTIAL
SWING FROM DOUBLE DIGITS ABOVE TO AROUND 5 TO 15 DEGREES BELOW
NORMAL.
AVIATION
(18Z TAFS)
ISSUED AT 1146 AM CST THU DEC 25 2025
NO SIGNIFICANT CHANGE FROM PREVIOUS DAYS. EVEN AT THIS EARLY
AFTERNOON HOUR, VIS AND CIGS ARE STILL IMPROVING AND LIFTING. ONCE
AGAIN THIS EVENING, WE WILL SEE AREAS OF DENSE FOG BECOMING
WIDESPREAD. AGAIN WITH DAYS PREVIOUS, WE WILL SEE IMPROVEMENTS
BEGINNING AT THE EARLIEST AROUND MID MORNING AS DAYTIME HEATING
AND MIXING ERODES THE FOG.
MARINE
ISSUED AT 1146 AM CST THU DEC 25 2025
A LIGHT ONSHORE FLOW WILL PREVAIL THROUGH SUNDAY AFTERNOON, KEEPING
A DAILY RISK OF SEA FOG IN THE FORECAST. DUE TO ONGOING DENSE MARINE
FOG AND ELEVATED PROBABILITIES OF FOG PERSISTING, THE DF.Y WAS
EXTENDED INTO NOON TOMORROW. BRIEF PERIODS OF INCREASED VISIBILITIES
WILL BE POSSIBLE FOR ALL MARINE ZONES THIS AFTERNOON, HOWEVER.
A STRONG OFFSHORE FLOW IS EXPECTED IN THE WAKE OF A COLD FRONT
FORECAST TO PUSH THROUGH THE COASTAL WATERS LATE SUNDAY NIGHT INTO
EARLY MONDAY. THIS WILL ASSIST WITH CLEARING THE FOG, HOWEVER WITH
ELEVATED OFFSHORE FLOW AND GUSTS PREDICTED, A SC.Y WILL BE LIKELY
AND A GL.A MAY BECOME NECESSARY.
FIRE WEATHER
ISSUED AT 1146 AM CST THU DEC 25 2025
LIGHT SOUTHERLY WINDS WILL PERSIST THROUGH SUNDAY AFTERNOON. MIN
AFTERNOON RELATIVE HUMIDITY VALUES WILL BE IN THE 60 TO 70 PERCENT
RANGE. AN UPPER LEVEL RIDGE OVERHEAD WILL HELP KEEP SIGNIFICANT
RAINFALL OUT OF THE FORECAST PRIOR TO SUNDAY NIGHT BEFORE A COLD
FRONT INITIATES A FEW SCATTERED SHOWERS. WINDS WILL THEN SHIFT OUT
OF THE NORTH WITH GUSTY CONDITIONS POSSIBLE THROUGH MONDAY
AFTERNOON. IN THE MEANWHILE, THERE WILL BE THE POTENTIAL FOR
WIDESPREAD FOG DURING THE NIGHT AND EARLY MORNING HOURS EACH DAY.
