ISSUED AT 108 PM CDT SUN MAR 22 2026
IN THE UPPER LEVELS, A BROAD UPPER LEVEL RIDGE IS CENTERED ROUGHLY
ACROSS SOUTHERN AZ/NM AND NORTHERN MEXICO BUT SPREAD ACROSS MUCH OF
THE SOUTHERN US. SHORTWAVES HAVE BEEN TRACKING THROUGH THE NORTHERN
PERIPHERY OF THAT RIDGE AND HAS ONE DOES SO TONIGHT, THE EASTERN
SIDE OF THE UPPER RIDGE WILL WEAKEN SLIGHTLY. WHAT THAT DOES IS
ALLOW SURFACE RIDGE CENTERED OVER THE EASTERN GULF TO MOVE IN ACROSS
THE NORTHERN GULF COAST, RIGHT NEAR THE LOCAL COASTAL WATERS. WINDS
LOCALLY WILL DROP AND RADIATIONAL COOLING TAKES PLACE TONIGHT. MODEL
SOUNDINGS DEPICT THIS SETUP WITH A DECENT LOW LEVEL INVERSION
DEVELOPING AFTER MIDNIGHT. STRONGER INVERSION WITH LLVL SATURATION
IN BATON ROUGE METRO VS WEAKER ONE EAST OF I-55. CONFIDENCE
DECREASES AT AREAS ALONG/EAST OF THERE AND THUS KEPT DENSE FOG
ADVISORY GENERALLY LIMITED TO BATON ROUGE METRO TO HOUMA, NOT QUITE
TO NEW ORLEANS OR THE NORTHSHORE OF LAKE PONTCHARTRAIN.

LONG TERM
(TUESDAY THROUGH SATURDAY NIGHT)
ISSUED AT 108 PM CDT SUN MAR 22 2026
AS THE ABOVE MENTIONED WEAK SHORTWAVE EMBEDDED WITHIN THE
NORTHEASTERN PERIPHERY OF THE RIDGE PASSES JUST NORTHEAST OF THE
CWA, A BACKDOOR FRONT DOES APPROACH THE REGION. HOWEVER, THAT
AIRMASS WON'T MAKE IT THROUGH AND TEMPS BARELY DROP FROM TEMPORARY
EROSION OF THE EASTERN SIDE OF THE RIDGE ALOFT.
THE CENTER OF THAT UPPER RIDGE LOOKS TO SHIFT EAST, CLOSER TO THE
CWA AND SPREAD FARTHER EAST TO THE ATLANTIC AS THE SHORTWAVE LIFTS
EAST. THAT'LL ALLOW TEMPS TO MODERATE AND LOWS/HIGHS WARM TO 10 TO
15 DEGREES ABOVE NORMAL. IN ADDITION, STRONG SUBSIDENCE FROM THAT
HIGH PRESSURE DOME WILL CONTINUE TO KEEP RAIN CHANCES OUT OF THE
FORECAST FOR THE REMAINDER OF THE FORECAST PERIOD.

ISSUED AT 108 PM CDT SUN MAR 22 2026
SCATTERED CU FIELD IS DEVELOPING ACROSS SELA AND SPREADING
NORTHEASTWARD. DECK HEIGHTS ARE JUST ABOVE MVFR/VFR THRESHOLD AND
SHOULD LIFT HIGHER AS THE AFTERNOON PROGRESSES BEFORE DISSIPATING

MARINE
ISSUED AT 108 PM CDT SUN MAR 22 2026
A BROAD AREA OF HIGH PRESSURE CENTERED OVER THE EASTERN GULF WILL
KEEP A PREVAILING SOUTHWESTERLY WIND OF AROUND 10 KNOTS IN PLACE
THROUGH MONDAY. LATE TUESDAY, A WEAK FRONT WILL STALL NEAR THE COAST
AND MAY EVEN GET INTO THE NEARSHORE WATERS TUE NIGHT. WINDS MAY
BRIEFLY SHIFT TO THE NORTH AT 5 TO 10 KNOTS WHERE THE FRONT PASSES.
BY WEDNESDAY, SOUTHERLY FLOW OF 5 TO 10 KNOTS AND LOW END SEAS OF 1
TO 2 FEET WILL RETURN AS HIGH PRESSURE OVER THE EASTERN GULF ONCE
AGAIN BECOMES THE DOMINANT FEATURE. THESE CONDITIONS WILL LAST
THROUGH THE END OF NEXT WEEK.
