DISCUSSION
ISSUED AT 204 AM CDT TUE MAR 24 2026
DISCUSSION...A WEAK FRONTAL BOUNDARY PRESENTLY BISECTS THE REGION
FROM WEST TO EAST WITH ABOUT A 15 DEGREE SPREAD IN DEWPOINTS ON
EITHER SIDE OF THE BOUNDARY. AREAS OF DENSE FOG ARE EXPECTED TO
DEVELOP AGAIN THIS MORNING SOUTH OF THE FRONT AND A DENSE FOG
ADVISORY REMAINS IN EFFECT UNTIL 9 AM THIS MORNING. THE FRONTAL
BOUNDARY WILL BE QUICK TO WASH OUT TODAY WITH SOUTHERLY WINDS
BECOMING REESTABLISHED BY THIS AFTERNOON PUSHING DEWPOINTS ACROSS
CENTRAL LOUISIANA BACK INTO THE UPPER 50S TO LOWER 60S. THE
INCREASING DEWPOINTS COMBINED WITH CLEAR SKIES AND LIGHT WINDS WILL
SUPPORT THE DEVELOPMENT OF ANOTHER ROUND OF POTENTIALLY DENSE FOG
LATE TONIGHT INTO WEDNESDAY MORNING. HIGH PRESSURE OVER THE
SOUTHEASTERN U.S. WILL MAINTAIN THE SOUTHERLY FLOW AND WARM,
TROPICAL AIRMASS THROUGH EARLY FRIDAY SUPPORTING SOME AMOUNT OF FOG
EACH NIGHT. A MORE POTENT, ALBEIT DRY, FRONTAL BOUNDARY WILL PUSH
THROUGH THE REGION LATE FRIDAY WITH A COOL, CONTINENTAL AIRMASS
FILTERING INTO THE REGION FOR THE WEEKEND WHICH WILL DROP
TEMPERATURES CLOSER TO SEASONAL NORMALS.

AVIATION
(06Z TAFS)
ISSUED AT 204 AM CDT TUE MAR 24 2026
THE NEXT FEW HOURS WILL BE SOMEWHAT TRICKY WITH REGARDS TO
VISIBILITIES AT BPT AND LCH. AREAS OF SHALLOW GROUND FOG HAVE
DEVELOPED AT BOTH SITES, BUT A WEAK FRONTAL BOUNDARY IS
APPROACHING AND WILL BE MOVING THROUGH THESE SITES BETWEEN 06-08Z.
A 10-15 DEGREE DROP IN DEWPOINTS ARE EXPECTED TO DISSIPATE THE
DEVELOPING FOG AND THE TAFS REFLECT THIS. HOWEVER, CAN'T RULE OUT
SOME REDEVELOPMENT THROUGH THE EARLY MORNING IN A FEW AREAS
DESPITE THE DRIER AIR SO THESE SITES MAY BE AMENDED IF
VISIBILITIES BEGIN TRENDING DOWN AGAIN. ELSEWHERE, VFR CONDITIONS
ARE EXPECTED TO PREVAIL THROUGH THE TAF PERIOD. A BRIEF PERIOD OF
LIGHT EAST NORTHEASTERLY WINDS BEHIND THE FRONT THIS MORNING WILL
TURN BACK OUT OF THE SOUTH THIS AFTERNOON LIFTING MOISTURE BACK
INLAND. THIS WILL SUPPORT ANOTHER ROUND OF FOG DEVELOPMENT LATE
TONIGHT INTO EARLY WEDNESDAY MORNING.
