SHORT TERM
(THIS EVENING THROUGH SATURDAY NIGHT)
ISSUED AT 1202 PM CDT FRI MAR 20 2026
UPPER TROUGH OFF THE ATLANTIC COAST WITH UNSEASONABLY STRONG UPPER
RIDGING CENTERED NEAR PHOENIX. AT THE SURFACE, HIGH PRESSURE
EXTENDED FROM THE CAROLINAS TO THE NORTH CENTRAL GULF. UNDER MOSTLY
CLEAR SKIES, TEMPERATURES RANGED FROM THE UPPER 60S TO MID 70S AT
NOON. FORECAST SOUNDINGS WOULD JUSTIFY HIGH TEMPERATURES THIS
AFTERNOON BETWEEN 75 AND 80 FOR MUCH OF THE AREA.
ONLY REAL FORECAST ISSUE THROUGH THE WEEKEND IS WHETHER FOG DEVELOPS
AROUND SUNRISE THE NEXT COUPLE MORNINGS. THE HIGHER DEW POINTS
THE NEXT COUPLE NIGHTS ARE OVER THE ATCHAFALAYA RIVER BASIN, AND
THAT'S WHERE THE HIGHEST PROBABILITIES ARE AT. EVEN THERE,
PROBABILITIES OF VISIBILITIES LESS THAN 3 MILES IS ON THE ORDER OF
10 TO 20 PERCENT. WILL MENTION PATCHY FOG THERE, BUT THREAT
DOESN'T APPEAR HIGH ENOUGH TO JUSTIFY ADVISORIES. HIGH
TEMPERATURES SATURDAY LIKELY TO BE IN THE LOWER 80S IN MOST AREAS,
BUT COASTAL AREAS PROBABLY WILL ONLY GET TO THE UPPER 70S, AS
NEARBY WATER TEMPERATURES ARE STILL IN THE 60S. OVERNIGHT LOWS
WILL GRADUALLY BE CREEPING UPWARD, IN THE 50S TONIGHT, THEN SOME
AREAS WILL REMAIN IN THE LOWER 60S TOMORROW NIGHT.
LONG TERM
(SUNDAY THROUGH THURSDAY NIGHT)
ISSUED AT 1202 PM CDT FRI MAR 20 2026
SHORTWAVES IN NORTHWESTERLY UPPER FLOW WILL TRY TO SUPPRESS THE
EASTERN EXTENT OF THE UPPER RIDGE ON A COUPLE OF OCCASIONS OVER
THE NEXT WEEK. THE FIRST WILL BE SATURDAY NIGHT INTO SUNDAY
MORNING, AND THE SECOND AT THE MIDDLE OF NEXT WEEK. MOISTURE
CONTINUES TO BE LACKING, WITH LITTLE OR NO THREAT OF PRECIPITATION
THROUGH THE END OF NEXT WEEK. MUCH ABOVE NORMAL TEMPERATURES TO
CONTINUE WITH HIGHS UPPER 70S TO MID 80S, AND LOWS IN THE 50S AND
LOWER 60S.
AVIATION
(00Z TAFS)
ISSUED AT 626 PM CDT FRI MAR 20 2026
THE MAIN FORECAST CHALLENGE IS THE THREAT OF FOG AND LOW CEILINGS
DEVELOPING AT BTR AND MCB BETWEEN 10Z AND 13Z. FOG PROBABILITIES
ARE IN THE 40 TO 60 PERCENT RANGE, OR MODERATELY HIGH, FOR SOME
FOG AND LOW STRATUS TO FORM AT THESE TERMINALS AROUND DAYBREAK.
CONDITIONS ALSO LOOK FAVORABLE WITH CLEAR SKIES, LIGHT BOUNDARY
LAYER WINDS OF LESS THAN 10 KNOTS, AND STRONG RADIATIONAL COOLING
ANTICIPATED TONIGHT. GIVEN THESE HIGHER PROBABILITIES AND
FAVORABLE CONDITIONS, A PERIOD OF REDUCED VISIBILITIES BETWEEN 2
AND 3 MILES AND CEILINGS OF 300 TO 500 FEET IS IN THE FORECAST FOR
BTR AND MCB FROM 10Z THROUGH 14Z. OUTSIDE OF THE FOG THREAT, VFR
CONDITIONS WILL BE THE RULE THROUGH THE ENTIRE FORECAST PERIOD.
MARINE
ISSUED AT 1202 PM CDT FRI MAR 20 2026
SURFACE HIGH PRESSURE IS CENTERED JUST INTO THE NORTHERN GULF. THIS
WILL KEEP WIND GENERALLY LIGHT AND VARIABLE FOR A COUPLE MORE DAYS.
BY SUNDAY, SOUTHWESTERLY FLOW WILL BECOME BETTER ESTABLISHED. THAT
RIDGE WILL THEN DRIFT BACK NORTH TOWARDS THE NORTHERN GULF AGAIN,
RESULTING IN SUBSIDING WINDS AND MINIMAL WAVE/SEAS IMPACTS
THROUGH AT LEAST WEDNESDAY.
