KEY MESSAGES
UPDATED AT 701 PM CST WED DEC 24 2025
- WIDESPREAD DENSE FOG IS EXPECTED AGAIN TONIGHT AND CHRISTMAS
MORNING. COMMUTERS AND HOLIDAY TRAVELERS ARE URGED TO ALLOW
EXTRA TIME TO THEIR DESTINATIONS. THE ENVIRONMENT IS VERY
CONDUCIVE TO SUPER FOG FORMATION NEAR AND DOWNWIND OF FIRES.

IN THE UPPER 70S AND QUITE POSSIBLY REACHING THE LOW 80S WITH
OVERNIGHT LOWS AROUND 60 DEGREES.

FRONT.
SHORT TERM
(TONIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 701 PM CST WED DEC 24 2025
NOT MUCH CHANGE HAS TAKEN PLACE AS FAR AS THE ENVIRONMENT IS
CONCERNED. THE DEW PT HAS NOT EVEN CHANGED ONE DEGREE FOR FOG
PRODUCTION WHICH REMAINS AT 63-64F. THE WET BULB COOLING IS STILL
IMPRESSIVE WHEN COMPARED TO YESTERDAY'S AND ALMOST EXACTLY EQUAL(YESTERDAY'S
SOUNDING SHOWED A 10C COOLING IN 1540FT TODAY'S SHOWS A 6C
COOLING IN 900FT). THIS COMES TO 1C/154FT FOR YESTERDAY COMPARED
TO 1C/150FT FOR TODAY. YELP, PRETTY MUCH EXACTLY THE SAME AND
STILL STRONG. THIS SAME SCENARIO REMAINS THROUGH AT LEAST FRIDAY
NIGHT. BUT THERE COULD BE SOME SUBTLE CHANGES, NOT IN GETTING FOG
BUT HOW IT FORMS. IT COULD BECOME MORE ADVECTIVE INSTEAD OF
CONGLOMERATE BY FRIDAY MORNING AND AGAIN FRIDAY NIGHT.
LONG TERM
(SATURDAY NIGHT THROUGH WEDNESDAY NIGHT)
ISSUED AT 701 PM CST WED DEC 24 2025
A COLD FRONT WILL MOVE THROUGH AT THE BEGINNING OF THE WEEK
FLUSHING THE FOG AWAY. THERE WILL BE SOME SHOWERS WITH THIS BUT
THEY DON'T LOOK TO BE HEAVY. THERE ARE NO MODERATE OR STRONG
CHANCES OF STORMS WITH THIS EITHER AS MOST IF NOT ALL OF THESE
WILL BE OFFSHORE AND ALSO WELL NORTH OF THE AREA. WE WILL NEED TO
GET CLOSER TO THIS FROPA TO TELL EXACTLY WHAT AND WHERE, BUT THIS
IS A FIRST GLIMPSE INTO WHAT SHOULD OCCUR.
AVIATION
(00Z TAFS)
ISSUED AT 701 PM CST WED DEC 24 2025
CIGS AND VIS WILL BE ONCE AGAIN IN IFR AND LIFR ONCE THESE
CONDITIONS SET IN THIS MORNING. SAME TIMING AS FAR AS EROSION OF
THE FOG DECK TO SET VFR. THIS SAME SCENARIO OCCURS AGAIN TONIGHT
INTO FRI MORNING.
MARINE
ISSUED AT 701 PM CST WED DEC 24 2025
FOG WILL REMAIN THROUGH MUCH OF EACH DAY AND WIDESPREAD OVERNIGHT
INTO THE END OF THE WEEK WHICH WILL LIKELY BRING ADDITIONAL
MARINE DENSE FOG ADVISORIES, ESPECIALLY RIGHT ALONG THE COAST.
THIS FOG MAY NOT LIFT IN MANY AREAS NEAR THE COAST, BUT AS LAND
HEATING GETS GOING, WE SHOULD SEE SOME EROSION OVER WATER BODIES
THAT CAN MOVE THIS AIR OVER THE WATER. THE NEXT FRONT IS DUE INTO
THE REGION EARLY NEXT WEEK. THIS WILL DEFINITELY MOVE THE FOG
ISSUE AWAY. LOOK FOR WINDS TO BE ON THE INCREASE VERY LATE IN THE
PERIOD WITH THIS FEATURE AS WELL WHICH SHOULD PRODUCE HEADLINES.
