UPDATE
ISSUED AT 644 AM CST THU NOV 6 2025
AREAS OF DENSE FOG CONTINUE TO SPREAD NORTH AND HAVE NOW MADE IT
TO THE I-20 CORRIDOR WITH BOTH LONGVIEW AND SHREVEPORT ASOS SITES
REPORTING RAPIDLY REDUCING VISIBILITY VALUES. THUS, SENT OUT A
QUICK UPDATE TO ADD ANOTHER ROW OF COUNTIES AND PARISHES ALONG THE
NORTHERN EDGE OF THE ONGOING ADVISORY. /05/
DISCUSSION
ISSUED AT 1105 PM CST WED NOV 5 2025
ANOTHER QUIET AND CLEAR NIGHT ACROSS THE FOUR STATE REGION
FOLLOWING A RATHER WARM AFTERNOON AS HIGHS APPROACHED AND EVEN
EXCEEDED 80 DEG F. IT WILL BE A RINSE AND REPEAT THEME HEADING
INTO THURSDAY AS HIGHS WILL BE VERY SIMILAR TO THIS AFTERNOON.
BEFORE WE GET THERE THOUGH, DENSE FOG WILL BE THE WEATHER FOCUS
THROUGH THE EARLY MORNING HOURS OF THURSDAY AND THROUGH THE
MORNING COMMUTE AS THE POTENTIAL FOR LOW VISIBILITY WILL COVER A
GOOD MAJORITY OF THE SOUTHERN ZONES OF THE FORECAST AREA.
GIVEN THE POTENTIAL FOR VISIBILITY AT OR BELOW A QUARTER OF A
MILE, A DENSE FOG ADVISORY WAS ISSUED THIS EVENING, AND IS SET TO
GO INTO EFFECT AT 3 AM CST THURSDAY MORNING. IT IS WORTH
MENTIONING THAT AREAS NORTH OF THE ADVISORY ZONE, MEANING ALONG
THE I-20 CORRIDOR AND NORTH, WILL HAVE THE POTENTIAL FOR PATCHY
FOG, AND ISOLATED INSTANCES OF DENSE FOG, BUT THE CONFIDENCE FOR
WIDESPREAD IMPACTS WAS NOT HIGH ENOUGH TO JUSTIFY BRINGING THE
ADVISORY FURTHER NORTH AT THIS TIME. IF THIS CHANGES, AN EXPANSION
IN THE ADVISORY WILL BE MADE. FOR NOW THOUGH, THE ADVISORY IS SET
TO BE IN EFFECT UNTIL 9 AM CST THURSDAY. HI-RES SOLUTIONS THIS
EVENING HAVE BEEN CONSISTENT WITH THE FOG BURNING OFF THROUGH MID
MORNING, WITH A RETURN TO CLEAR SKIES BY THE AFTERNOON.
LOOKING THROUGH THE END OF THE WEEK, MODEL SURFACE VORTICITY
OUTPUT CONTINUES TO HIGHLIGHT A COMMON THEME IN THAT WEAK SURFACE
BOUNDARIES APPROACHING THE FA WILL EITHER STALL OUT, WASH OUT
ENTIRELY OR NOT REACH THE REGION AT ALL. AT THE SAME TIME,
CONFIDENCE CONTINUES TO GROW THAT THE EASTERN PORTION OF THE FA
WILL MISS OUT ON RAIN CHANCES COMPLETELY AS MOISTURE DISPLACEMENT
AND SUFFICIENT FORCING WILL BE MOSTLY EAST OF THE REGION FRIDAY
AFTERNOON, WITH THE FOCUS FOR SHOWERS AND STORMS HIGHLIGHTING THE
ARKLAMISS VICINITY AND AREAS EAST.
THE REAL WEATHER STORY IN THE LONG TERM IS THE CHANCE FOR SOME OF
OUR COLDEST TEMPERATURES OF THE SEASON AS A SHOT OF COLD AIR
RACES SOUTHWARD SUNDAY NIGHT AND INTO MONDAY AM. BASE LONG RANGE
NBM CONTINUES TO SUGGEST LOWS IN THE UPPER 20'S AND LOW AND MID
30'S ACROSS THE REGION MONDAY AM, WITH SIMILAR LOWS FOR TUESDAY
AM. FOR NOW, MONDAY AM LOOKS TO BE THE COLDEST OF THE TWO NIGHTS,
AND SOMETHING TO MONITOR AS SOME OF THE AREA CLIMATE SITES MAY
SEE THEIR FIRST CHANCE AT TEMPS NEAR FREEZING FOR THE FIRST TIME
THIS SEASON. THOUGH RAIN WOULD BE WELCOMED WITH THE LATE WEEKEND
FRONTAL PASSAGE, WE KNOW THAT THESE STRONGER FRONTS CAN INCREASE
SEVERE POTENTIAL AT TIMES. THE GOOD NEWS IS THAT THE BOUNDARY
LOOKS TO BE DRY, AND NO SEVERE POTENTIAL IS EXPECTED.
