KEY MESSAGES
- FOG LEADING TO REDUCED VISIBILITIES IS EXPECTED EACH NIGHT INTO
THE MORNING HOURS, ESPECIALLY OVER THE NEAR SHORE WATERS AND
COASTAL LAKES AND BAYS, FOR THE REMAINDER OF THE WEEK.
- NEAR RECORD HIGH TEMPERATURES EACH DAY THROUGH THE END OF
CHRISTMAS WEEK.
- A COLD FRONT IS EXPECTED ON SUNDAY TO BRING COOLER WEATHER TO
BEGIN NEXT WEEK.
SHORT TERM
(TONIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 559 PM CST WED DEC 24 2025
A SURFACE HIGH PRESSURE REMAINS ATOP THE NE SIDE OF THE GULF COAST
REGION WITH A MID TO UPPER RIDGE CENTERED OVER MX AND THE GULF
COAST. OVER THE ENTIRETY OF THE SHORT TERM, LITTLE TO NO CHANGES
ARE EXPECTED TO EITHER PRESSURE SYSTEM. THIS HAS LED TO, AND WILL
CONTINUE, NEAR RECORD HIGH TEMPERATURES THIS HOLIDAY SEASON ALONG
WITH PERSISTENT PATCHY TO DENSE FOG.
HIGHS FOR THE NEXT FEW DAYS WILL BE REACHING INTO THE UPPER 70S TO
LOWER 80S. THIS IS ABOUT 14 TO 21 DEGREES HIGHER THAN
CLIMATOLOGICAL NORMALS FOR THIS TIME OF YEAR AND THERE IS AT LEAST
A LOW END POSSIBILITY OF SETTING NEW DAILY HIGHS EACH DAY. LOWS
WILL ONLY DROP INTO THE UPPER 50S TO MID 60S, WHICH IS 12 TO 18
DEGREES HIGHER THAN NORMS. FOR THOSE WHO STILL GIVE THEIR
ATTENTION TO THE “WARMEST MINIMUM” TEMPS, IT’S LIKELY THAT THOSE
RECORDS WILL NOT BE TOUCHED.
FOG, AS WE HAVE EXPERIENCED FOR THE LAST FEW DAYS, WILL CONTINUE
TO BE A CONCERN. THANKS TO THE POSITIONING OF THE SURFACE HIGH, WE
WILL HAVE A STEADY STREAM OF WARM AND MOIST SOUTHERLY FLOW MOVING
INLAND. DEWPOINTS WILL BE IN THE LOW TO UPPER 60S, BLOWING OVER
SSTS IN THE LOW TO MID 60S. THIS WILL HELP ADVECT IN SOME MARINE
FOG, ALONG WITH OTHER PLACES SEEING TYPICAL RADIATIONAL FOG.
ANOTHER DENSE FOG ADVISORY WILL BE IN EFFECT TONIGHT FROM 9 PM CST
TO CHRISTMAS MORNING AT 10 AM CST. PROBABLY NOT THE “WHITE
CHRISTMAS” ONE WOULD HOPE FOR, BUT THE ONE WE WILL GET FOR NEAR
THE MAJORITY OF THIS PART OF THE GULF COAST.
LONG TERM
(SATURDAY THROUGH NEXT TUESDAY)
ISSUED AT 559 PM CST WED DEC 24 2025
OVER THE LONG TERM, THE UPPER RIDGE CENTERED OVER MX / THE GULF
WILL FLATTEN AS AN UPPER TROUGH OVER CANADA MOVES INTO THE GREAT
LAKES REGION. THIS WILL SEND A STRONG COLD FRONT THROUGH THE
CENTRAL CONUS EASTWARD THIS WEEKEND AND SPECIFICALLY THIS SUNDAY
INTO MONDAY FOR OUR CWA. 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 14 DEGREES BELOW NORMAL.
