SHORT TERM
(TONIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 1139 PM CST TUE DEC 23 2025
NW GULF COAST REGION REMAINS TO THE WEST OF SFC HIGH PRESSURE AND
UNDERNEATH A STRONG MID/UPPER LEVEL RIDGE. THIS HAS LED TO THE
RECORD TO NEAR RECORD SPELL OF WARM TEMPERATURES AND HELPED KEEP A
RISK OF BOTH MARINE AND INLAND FOG IN THE FORECAST. THE RIDGE WILL
BEGIN TO FLATTEN OUT THU INTO FRI, BUT OTHERWISE NO SIGNIFICANT
CHANGE IS EXPECTED IN THE NEAR TERM, WHICH MEANS THE UNSEASONABLY
WARM AND HUMID WEATHER WILL CONTINUE, WITH THE ONLY CHANCE OF WHITE
THIS CHRISTMAS COMING IN THE FORM OF FOG. SANTA WILL DEFINITELY NEED
RUDOLPH THIS YEAR.
GETTING A LITTLE MORE SPECIFIC, HIGHS FOR THE NEXT COUPLE OF DAYS
WILL CONTINUE TO TOP OUT IN THE MID/UPPER 70S TO NEAR 80, WITH LOWS
IN THE UPPER 50S TO LOWER 60S. BASED ON OBSERVED TEMPERATURES
TODAY, THE NBM LOOKED A LITTLE UNDERDONE WITH HIGHS THE NEXT COUPLE
OF DAYS, SO OPTED TO BLEND IN SOME NBM90. IN TERMS OF FOG, A LIGHT
BUT STEADY MOIST ONSHORE FLOW PUSHING AN AIRMASS CHARACTERIZED BY
TDS IN THE UPPER 60S ATOP SSTS IN THE LOWER TO AT BEST MID 60S WILL
CONTINUE TO RESULT IN THE RISK OF MARINE FOG, THOUGH THIS LOOKS TO
WORSEN IN THE LONG TERM AS WINDS SHIFT TO A MORE SW DIRECTION AND
SOURCE REGION TDS INCREASE TO AROUND 70. INLAND FOG WILL ALSO
CONTINUE TO BE A CONCERN VIA BOTH ADVECTIVE AND RADIATIVE
PROCESSES.
LONG TERM
(SATURDAY THROUGH NEXT TUESDAY)
ISSUED AT 1139 PM CST TUE DEC 23 2025
THE SFC HIGH AND FLAT MID/UPPER RIDGE WILL SHIFT MORE TOWARD THE SE
ON OVER THE WEEKEND, WHILE A POTENT UPPER TROF SWINGS THROUGH THE
NORTHERN PLAINS INTO THE GREAT LAKES. AS THIS FEATURE TRANSLATES
EWD WITH ADDITIONAL SHORTWAVE ENERGY DIVING INTO ITS WESTERN FLANK,
GLOBAL MODELS CONTINUE TO ADVERTISE A STRONG COLD FRONT PUSHING
THROUGH THE AREA LATE SUN NIGHT INTO MON. ABOVE NORMAL WARMTH WILL
CONTINUE THROUGH THE WEEKEND, WITH MUCH COLDER TEMPERATURES EXPECTED
TO START THE UPCOMING WORK WEEK AND CLOSE OUT THE YEAR.
AVIATION

COASTAL WATERS LATE SUNDAY NIGHT INTO EARLY MONDAY.
FIRE WEATHER

RAINFALL OUT OF THE FORECAST. THERE WILL BE THE POTENTIAL FOR
WIDESPREAD DENSE FOG DURING THE NIGHT AND EARLY MORNING HOURS EACH
DAY.
