DISCUSSION
ISSUED AT 345 PM EDT WED APR 22 2026
THRU TONIGHT...WHILE MID LEVELS REMAIN VERY DRY, THERE HAS BEEN AN
UPTICK IN MOISTURE IN THE LOW LEVELS AS WELL AS THE UPPER LEVELS.
SO A LITTLE MORE CLOUDINESS THIS AFTN IN THE FORM OF MARINE
STRATOCU PANCAKING BENEATH A PERSISTENT INVERSION NEAR 850 MB AS
WELL AS SOME ALTOCU/CIRROCU. ISOLATED SHOWERS/SPRINKLES WILL PUSH
ONSHORE THE BREVARD/INDIAN RIVER COASTS INTO EARLY EVE.
THU-WED...IN THE LOW LEVELS, HIGH PRESSURE CENTER WILL CONTINUE TO
PUSH SOUTH AND EAST WELL OFFSHORE THE CAROLINA COAST WED AND THU
WITH A RIDGE AXIS EXTENDING WESTWARD ACROSS NORTH FL. THIS WILL
GRADUALLY WEAKEN THE PRESSURE GRADIENT WHICH WILL DECREASE OUR
WINDS WITH NOTICEABLY LESS GUSTINESS THU AND FRI. ALOFT, A "BAGGY"
TROUGH WILL DEVELOP OVER THE AREA BY THU AND SHIFT EAST OF THE
AREA THIS WEEKEND. SO SOME GRADUAL MOISTENING WILL TAKE PLACE IN
THE MID LEVELS AND WEAKEN THE PERSISTENT INVERSION. SUFFICIENT LOW
LEVEL MOISTURE WILL SUPPORT ISOLATED SHOWERS OVER THE ATLC DURING
THE OVERNIGHT/MORNING THEN TRANSITIONING TO LAND AREAS DURING THE
DAY. ISOLATED TO SCATTERED SHOWERS/STORMS THIS WEEKEND WILL BE
MAINLY ASSOCD WITH SEA BREEZE COLLISIONS, ESPECIALLY SUNDAY WHEN
RAIN CHANCES (25-35%) ARE HIGHEST. ANY LIGHTNING STRIKES THAT
OCCUR WILL HAVE POTENTIAL TO SPARK BRUSH FIRES GIVEN THE DRY
ANTECEDENT CONDITIONS. REINFORCING HIGH PRESSURE IS FORECAST TO
BUILD OVER THE AREA MONDAY THEN MOVE OUT OVER THE SW ATLC WITH A
TRAILING RIDGE AXIS SLIPPING DOWN THE FL PENINSULA MID WEEK.
LIMITED RAIN CHANCES WILL CONTINUE.
NEAR SEASONAL HIGH TEMPS THU, THEN A WARMING TREND THIS WEEKEND
WITH MAX TEMPS IN THE UPPER 80S INTERIOR AND LOW TO MID 80S COAST.
MAX TEMPS MON HOLD STEADY THEN ADDITIONAL WARMING FOLLOWS WITH
LOWER 90S TUE AND LOW TO MID 90S WED OVER THE INTERIOR. DAILY SEA
BREEZES WILL KEEP THE COAST A LITTLE COOLER, BUT INCREASINGLY
DELAYED SEA BREEZES WILL ALLOW THE COAST TO WARM INTO THE UPPER
80S BY WED.
MARINE
ISSUED AT 345 PM EDT WED APR 22 2026
WILL ALLOW THE CAUTION HEADLINE TO FINALLY LAPSE ACROSS THE
SOUTHERN WATERS AS WINDS CONTINUE A SLOW DECLINE. CONDITIONS
GRADUALLY IMPROVE THROUGH FRI AS THE PRESSURE GRADIENT CONTINUES
TO RELAX AS A WEAK LOW-LEVEL RIDGE AXIS SETTLES ACROSS CENTRAL
FL. A MORE OFFSHORE W/SW FLOW WILL DEVELOP BY SUN AS THE RIDGE
AXIS PUSHES SOUTH OF THE LOCAL WATERS. AN E/SE SEA BREEZE 10-15
KNOTS WILL DEVELOP EACH AFTERNOON NEAR THE COAST. SEAS 3-4 FT
INTO THU SUBSIDE 2-3 FT FRI, 2 FT SAT AND 1-2 FT SUN. ISOLATED
LIGHT SHOWERS INTO THIS EVENING WILL PUSH ONSHORE SOUTH OF THE
CAPE. THEN ADDITIONAL SHOWERS POSSIBLE THU BUT REMAINING ISOLATED.
ISOLD-SCATTERED AFTN/EVENING LIGHTNING STORMS OVER LAND THIS

AVIATION
(06Z TAFS)
ISSUED AT 155 AM EDT THU APR 23 2026
VFR THROUGH THE PERIOD. LIGHT EASTERLY FLOW INCREASES 10-13 KTS
LATE THIS MORNING AND INTO THE AFTERNOON, AND LOCALLY HIGHER
GUSTS ARE FORECAST ALONG THE TREASURE COAST. LIGHT ONSHORE-MOVING
SHOWERS HAVE BEEN OBSERVED IN VICINITY OF VRB/FPR EARLY THIS
MORNING WITH MORE BROAD COVERAGE EXPANDING ALONG THE SOUTHERN
BREVARD AND TREASURE COAST AFTER SUNRISE. RECENT MODEL GUIDANCE
MAY SUGGEST A LOW CHANCE (20%) FOR SHOWERS IN VICINITY OF INTERIOR
TERMINALS THIS AFTERNOON, BUT CONFIDENCE IS TOO LOW TO MENTION IN
THE CURRENT TAF.
FIRE WEATHER

THIS EVENING. ADDITIONAL ISOLATED SHOWERS ARE FORECAST THURSDAY BUT
MOST AREAS WILL REMAIN DRY. MIN RH VALUES OF 35-40% ARE FORECAST
