DISCUSSION
ISSUED AT 941 PM CST TUE DEC 23 2025
A DENSE FOG ADVISORY IS IN EFFECT FOR PARTS OF NW LOUISIANA AND
DEEP EAST TEXAS OVERNIGHT TONIGHT THROUGH TOMORROW MORNING.
PERSISTANT MOISTURE ADVECTION OVER THE PAST SEVERAL DAYS, CLEARER
SKIES, AND WEAKENING SURFACE WINDS ARE PRIMING THE AREA FOR FOG
BOTH TONIGHT AND POSSIBLY CHRISTMAS EVE NIGHT. ASOS OBSERVATIONS
HAVE NATCHITOCHES DOWN TO 1 MI VISIBILITY AT THE TIME OF WRITING,
WITH OTHER SURROUNDING AREAS BEGINNING TO DROP AS WELL. FOG IS
GENERALLY EXPECTED TO SPREAD SOUTH TO NORTH OVERNIGHT, WITH THE
GREATEST IMPACTS STAYING ALONG AND SOUTH OF THE I-20 CORRIDOR.
THE CURRENT ADVISORY IS IN EFFECT UNTIL 10 AM ON WEDNESDAY
MORNING, BUT MAY BE ADJUSTED LATER IF FOG IS SLOW TO MIX OUT.
THINGS LOOK TO STAY QUIET, ALBEIT MUCH WARMER THAN AVERAGE,
THROUGHOUT THE REST OF THE WEEK. HIGH TEMPERATURE RECORDS WERE SET
IN SHREVEPORT, TEXARKANA, EL DORADO, TYLER, AND LONGVIEW TODAY.
AND THANKS TO UPPER-LEVEL HIGH PRESSURE AND SURFACE SOUTHERLY
FLOW, THAT TREND WON'T CHANGE ANYTIME SOON. THE CURRENT FORECAST
HAS AREAS ALL ACROSS THE ARK-LA-TX REACHING THE UPPER 70S TO LOW
80S THROUGH CHRISTMAS DAY AND INTO THE WEEKEND. THE SAME SETUP
SHOULD KEEP CONDITIONS DRY AS WELL, DESPITE THE HIGHER SURFACE
MOISTURE.
COOLER CONDITIONS MAY BE ON THE HORIZON WITH A COLD FRONTAL
PASSAGE SUNDAY NIGHT. LONG RANGE MODELS SUGGEST THAT THIS FRONT
COULD BE STRONG ENOUGH TO BRING THE REGION TO BELOW-AVERAGE
TEMPERATURES MONDAY, WHICH ALMOST SOUNDS MIRACULOUS AFTER THE
WARM DECEMBER WE'VE HAD SO FAR. THIS FRONT COULD ALSO INITIATE
SOME RAIN AS IT MOVES THROUGH THE AREA, BUT EXACT LOCATION AND
TIMING WILL LIKELY BE IN FLUX WHILE IT STAYS IN THE LONG-TERM
PERIOD.

AVIATION
(12Z TAFS)
ISSUED AT 536 AM CST WED DEC 24 2025
WITH A VERY WARM AND MOIST LOWER ATMOSPHERE IN PLACE, THIS SETS UP
THE PERFECT CONDITIONS FOR AREAS OF DENSE FOG AND LOW CLOUDS AND
THAT IS EXACTLY WHAT WE HAVE PREVAILING ACROSS OUR AIRSPACE ATTM.
THE DENSE FOG FOR THE MOST PART HAS BEEN CONFINED TO PORTIONS OF
NC AND NE LA AS WELL AS SC AR WITH MORE IN THE WAY OF LIFR/IFR
CEILINGS NOTED ACROSS NE TX, EXTREME NW LA AND SW AR. AS WE GO
THROUGH THE MORNING, LOOK FOR THE FOG TO LIFT AND THE LOW CLOUDS
TO SCATTER OUT WITH VFR CONDITIONS RETURNING TO ALL TERMINALS BY
LATE MORNING OR VERY EARLY AFTERNOON. UNFORTUNATELY WITH THIS
ATMOSPHERE ANCHORED IN PLACE ACROSS OUR REGION, WE SHOULD SEE A
RETURN TO LOW VSBYS AND LOW CEILINGS ONCE AGAIN OVERNIGHT TONIGHT.
