CURRENT-TONIGHT...FAIRLY SHARP TEMP GRADIENT EARLY IN THE PERIOD
WITH M-U50S OVER THE FAR INTERIOR AND U60S TO NEAR 70F ALONG THE
COAST. ONSHORE WINDS NEAR 10-15 MPH FOR THE IMMEDIATE COAST AND
MAINLY 5 MPH OR LESS ACROSS THE INTERIOR. GENERALLY DRY CONDITIONS
CONTINUE, SAVE FOR ISOLD LIGHT RAIN SHOWERS OR SPRINKLES ACROSS
THE LOCAL COASTAL WATERS AND MAYBE A 10% CHANCE ALONG THE COAST,
HIGHEST CHANCES "MIGHT" BE COASTAL VOLUSIA AND COASTAL BREVARD.
AS WEAK HIGH PRESSURE RIDGING SETTLES NEAR NORTH-CENTRAL FL, THE
PRESSURE GRADIENT WILL SLOWLY BEGIN TO RELAX. WE STILL MAINTAIN
10-15 MPH OVER THE INTERIOR THIS AFTERNOON AND AROUND 15 MPH OR A
LITTLE HIGHER AT THE COAST, WITH STRONGER AFTERNOON GUSTS LIKELY.
PARTLY SUNNY SKIES WITH A FEW MORE CLOUDS ALONG THE COAST DUE TO
THE LOW-LEVEL ONSHORE FLOW. MAX TEMPS IN THE U70S ALONG THE COAST
AND NEAR 80F TO L80S INTO THE INTERIOR. SIMILAR OVERNIGHT MINS
UPCOMING WITH M-U50S TO NEAR 60F OVER THE INTERIOR AND 60S TO
NEAR 70F, AGAIN, ALONG THE COAST.
THU-TUE...FLOW ALOFT CONTINUES W/NW THRU THE PERIOD WITH PERIODIC
WEAK SHORTWAVE IMPULSES TRAVERSING THE FL PENINSULA. AT THE SURFACE,
WEAK HIGH PRESSURE RIDGING ACROSS THE CENTRAL FL PENINSULA
EVENTUALLY GETS NUDGED SEAWARD AND SOUTHWARD LATER IN THE WEEKEND
AND EARLY NEXT WEEK. THIS WILL KEEP THE PRESSURE GRADIENT RATHER
WEAK THRU MUCH OF THIS PERIOD. WILL SEE SOME MODEST INCREASES IN
MOISTURE THU INTO THE WEEKEND AS WELL AS DAILY SEA BREEZES WITH A
COLLISION ACROSS THE WESTERN PENINSULA THU EVENING, GRADUALLY MOVING
CLOSER TOWARDS THE CENTRAL FL PENINSULA THRU THIS WEEKEND. WE MAY
SEE SOME ISOLD SHOWERS DEVELOP INTO THE INTERIOR THU AFTERNOON, WITH
ISOLD (20%) LIGHTNING STORM CHANCES FRI-SAT, THEN MAYBE LOW-END SCT
(30%) THREAT ON SUN, BEFORE RETURNING TO ISOLD AGAIN FOR MON. ANY
POTENTIAL FRONTAL PASSAGES STAY MAINLY NORTHWARD.
NEAR SEASONAL HIGH TEMPS THU, THEN A WARMING TREND ENSUES FRI-TUE
WITH MAX VALUES APPROACHING M-U80S AND POTENTIAL 90F OVER THE
INTERIOR (SUN-TUE). ONSHORE FLOW WILL CONTINUE TO KEEP COASTAL AREAS
IN THE 60S TO NEAR 70F FOR MINS, AND DRIER AIR WILL ALLOW INTERIOR
LOCATIONS TO DIP INTO THE M-U50S ONE LAST MORNING FRI, WITH 60S
RETURNING ALMOST AREAWIDE SAT-WED MORNINGS.
MARINE
ISSUED AT 223 AM EDT WED APR 22 2026
WILL ALLOW SMALL CRAFT ADVISORIES TO EXPIRE, THOUGH CAUTIONARY
STATEMENTS WILL GREET THE NEW DAY ACROSS THE TREASURE COAST WATERS
FOR THIS MORNING. CONDITIONS GRADUALLY IMPROVE THROUGH THU AS THE
PRESSURE GRADIENT CONTINUES TO RELAX AS A WEAK LOW-LEVEL RIDGE AXIS
SETTLES CLOSER TO CENTRAL FL. A MORE S/SW FLOW WILL DEVELOP FRI-SAT
AS THE RIDGE AXIS PASSES OVERHEAD, THEN SOUTH OF THE LOCAL WATERS
ON SUN. AN E/SE SEA BREEZE 10-15 KNOTS WILL DEVELOP EACH AFTERNOON
NEAR THE COAST. SEAS RETURNING TO 3-5 FT AREAWIDE LATER THIS
MORNING, THEN 3-4 FT INTO THU, 2-3 FT FRI, AND 2 FT SAT-SUN.

WILL CONTINUE -SHRA AT TIMES IN THE KVRB-KFPR CORRIDOR INTO LATE
AFTERNOON WITH TEMPO CIGS TO 040-050 AT KVRB/KFPR. GUID DOES
INDICATE POTENTIAL FOR A FEW ATLC -SHRA TO MOVE ONSHORE TONIGHT
INTO THU MORNING MAINLY IN THE KTIX-KFPR CORRIDOR BUT PROBS TOO

COAST; THEN GUSTING 15 TO 20 MPH THURSDAY. ISOLATED ATLANTIC SHOWERS
