.DISCUSSION...
...SLIGHT RISK OF SEVERE STORMS TODAY MAINLY ALONG THE SPACE
AND TREASURE COASTS...
...TURNING COOLER THURSDAY INTO FRIDAY...

TODAY AND TONIGHT...
AN ENERGETIC DISTURBANCE AND ASCD JET MAXIMA MOVING ACROSS THE
FLORIDA PENINSULA FROM THE GULF WILL BRING WIDESPREAD SHOWERS AND
EMBEDDED STRONG LIGHTNING STORMS FROM THIS MORNING INTO MID
AFTERNOON. INCREASING WINDS IN THE ATMOSPHERE ALONG WITH PRESENCE
OF AFTERNOON SURFACE BOUNDARIES WILL ALLOW FOR SOME STORMS TO
BECOME STRONG TO POSSIBLY SEVERE. THE MAIN WINDOW FOR DEVELOPMENT
OF STRONG STORMS WILL BE ROUGHLY MID MORNING AND INTO THE EARLY
AFTERNOON.

A HIGHER CHANCE OF DEVELOPMENT OF LOCALLY SEVERE STORMS WILL BE
ALONG THE EAST COAST FROM CAPE CANAVERAL SOUTHWARD ACROSS THE
SPACE AND TREASURE COASTS WHERE AN EAST COAST BREEZE BOUNDARY IS
FORECAST TO BE PRESENT BY EARLY AFTERNOON. THE MAIN HAZARDS WILL
BE FREQUENT CLOUD TO GROUND LIGHTNING...SMALL HAIL AND PERIODS OF
BLINDING RAIN.

A BRIEF TORNADO OR WATER SPOUT WILL BE POSSIBLE IN THE STRONGEST
STORMS AS WELL. STORMS WILL MOVE RAPIDLY EAST AT 25 TO 35 MPH.
THIS CONVECTIVE SYSTEM PRECEDES AN APPROACHING LATE SEASON COLD
FRONT...POISED TO QUICKLY CROSS OVER THE AREA LATE TODAY. LATE
AFTERNOON/EVE PCPN WL QUICKLY COME TO AN END WITH PSG OF THE COLD
FRONT AND GRADUAL CLEARING WITH FALLING TEMPS INTO THE U50S TO
AROUND 60 BY DAYBREAK THU.

PERSONS SHOULD CLOSELY MONITOR WEATHER REPORTS FOR THE
POSSIBILITY OF A SEVERE WEATHER WATCH AND OR LOCAL WARNINGS.

THU-THU NIGHT...ALOFT A POTENT TROUGH WILL BE ENTRENCHED ACROSS THE
EASTERN SEABOARD. THE PREVIOUS SURFACE FRONT AND ASSOCIATED
PRECIPITATION WILL CONTINUE TO MOVE EAST AWAY FROM THE FLORIDA
PENINSULA EARLY IN THE PERIOD. WEAK SURFACE HIGH PRESSURE WILL BEGIN
TO BUILD INTO THE AREA FROM THE WEST. WNW/NW WINDS WILL BE BREEZY
(15-20 MPH) ON THIS DAY WITH FREQUENT HIGHER GUSTS AND MAY PROMPT
ISSUANCE OF A LAKE WIND ADVISORY. THIS NEW AIRMASS WILL BRING COOLER
AND MUCH DRIER CONDITIONS TO ECFL ABSENT OF ANY PRECIPITATION
CHANCES. AFTERNOON HIGHS WILL STILL MANAGE NEAR 80 DEGREES TO L80S.
UNSEASONABLY COOLER TEMPERATURES OVERNIGHT WITH LOWS FALLING INTO
THE 50S AREAWIDE...EXCEPT L60S STILL MANAGEABLE ACROSS SOUTHERN
MARTIN COUNTY.

FRI-FRI NIGHT...WEAK HIGH PRESSURE CONTINUES TO BUILD INTO THE
REGION FROM THE WEST WITH ITS CENTER NEAR SOUTHERN LOUISIANA. THE
PRESSURE GRADIENT RELAXES A BIT THOUGH WNW/NW WINDS WILL STILL
INCREASE IN THE LATE MORNING/AFTERNOON TO AROUND 15 MPH WITH SOME
HIGHER GUSTS. SKIES REMAIN MOSTLY CLEAR WITH NO THREAT FOR RAIN. THE
AFOREMENTIONED UPPER TROUGH WILL MOVE ONLY SLIGHTLY EASTWARD AND
WILL REMAIN ALIGNED ALONG THE EASTERN SEABOARD. UNSEASONABLY COOL
HIGHS ON FRI WITH MAINLY 70S AREAWIDE. OVERNIGHT LOWS STILL BELOW
SEASONAL AND GENERALLY IN THE 50S TO AROUND 60 DEGREES.

SAT-WED...UPPER TROUGHING NEAR THE EASTERN SEABOARD FINALLY WEAKENS
AND LIFTS NORTHEASTWARD BY LATE IN THE WEEKEND WITH ZONAL FLOW
OVERHEAD RETURNING INTO THE MIDDLE OF NEXT WEEK. SURFACE HIGH
PRESSURE TO THE WEST CONTINUES TO WEAKEN GRADUALLY AND WILL SLIDE
EASTWARD ACROSS THE FL PENINSULA ON SUN AND INTO THE WESTERN ATLC.
THE PRESSURE GRADIENT WILL REMAIN RELATIVELY WEAK WITH WINDS
BECOMING ONSHORE AGAIN ON MON THRU WED. A WEAK BACKDOOR COOL FRONT
WILL SLIDE BY THE AREA/JUST OFFSHORE FRI OVERNIGHT INTO EARLY SAT
BUT THE ATMOSPHERE WILL REMAIN TOO DRY/STABLE TO PRODUCE ANYTHING
OVER LAND. IN FACT...WILL CONTINUE TO KEEP PRECIPITATION OUT OF THE
FORECAST THRU AT LEAST TUE NIGHT. THE GFS SUGGESTS A SLUG OF
MOISTURE WILL MOVE INTO THE AREA ON WED WITH GREATEST CHANCES
SOUTHWARD FROM ORLANDO IF ANYTHING DOES DEVELOP. ONE MORE DAY FOR
BELOW SEASONAL TEMPERATURES ON SAT...THEN HIGHS QUICKLY CREEP BACK
WELL INTO THE 80S SUN-WED. LOWS WILL ALSO INCREASE BACK INTO THE 60S
AREAWIDE MON-WED.

.AVIATION...
EARLY DETERIORATING CIGS FROM N-S ASCD WITH THE APCHG WEATHER
SYSTEM WL EVENTUALLY BRING PERIODS OF MVFR/BRIEF IFR ALNG THE I-4
CORRIDOR MNLY FM 04/10Z-04/15Z WITH PERIODS OF IFR ASCD WITH

STORMS WL PRESENT SPECIFIC HAZARD TO ANY VESSELS OVER THE
INTRACOASTAL AND ATLC WATERS. RAPID EWD MOVEMENT OF STORMS AT 25
TO 35 KNOTS CAN BE EXPECTED. DETERIORATING OPEN WATER CONDITIONS
WILL CONTINUE WITH APPROACH AND PSG OF THE LATE SEASON COLD FRONT
LATER TODAY. HEADLINES WILL BE LIKELY FOR WINDS/SEAS OVER A
PORTION OF THE WATERS LATER TODAY.

THU-SUN...POST-FRONTAL CONDITIONS ON THU WITH WEAK HIGH PRESSURE TO
THE WEST BUILDING EASTWARD ACROSS THE COASTAL WATERS. THE CENTER OF
HIGH PRESSURE WILL MOVE ACROSS THE WATERS ON SUN. MAINLY
PRECIPITATION FREE CONDITIONS THROUGH THE PERIOD. THE PRESSURE
GRADIENT WILL REMAIN TIGHT ON THU INTO FRI AFTERNOON BEFORE
RELAXING...BUT THIS WILL BE SHORT-LIVED AS A WEAK BACKDOOR FRONT
WILL SWING SOUTHWARD ACROSS THE WATERS FRI OVERNIGHT INTO EARLY SAT.
CONDITIONS IMPROVE FROM SAT AFTERNOON INTO EARLY NEXT WEEK.

CAUTIONARY CONDITIONS FOR SMALL CRAFT OR POTENTIALLY LOW-END SMALL
CRAFT ADVISORY CRITERIA ON THU INTO FRI MORNING...THEN CAUTIONARY
CONDITIONS MAY RETURN AGAIN FRI OVERNIGHT INTO SAT MORNING DUE TO
