.DISCUSSION...

CURRENT...WEAK SURFACE TROUGH SAGGING INTO CTRL FL FROM THE N/W IS
PRODUCING A RATHER CHAOTIC WIND FLOW. ECSB HAS ALREADY FORMED
NEAR/NORTH OF THE TROUGH AXIS WITH LIGHT S-SSW TO ITS SOUTH. SKIES
HAVE BECOME PCLDY AS EXPECTED WITH SPOTTY SHOWERS POPPING UP IN MANY
AREAS. THUS FAR...TS HAVE REMAINED TO THE NORTH OF THE CWA...BUT
SOME HEAVIER SHOWERS TO THE WEST OF OKEE COUNTY LOOK LIKE THEY MAY
INTENSIFY INTO TS SHORTLY.

REMAINDER OF THIS AFTERNOON INTO TONIGHT...EXPECT STEADY INCREASE IN
COVERAGE AND INTENSITY OF CONVECTION AS BASE OF MID LEVEL TROUGH TO
THE NORTH PIVOTS EWD AND SEA/LAKE AND OUTFLOW BDRYS BEGIN TO DEVELOP
/INTERACT. UNLESS THE COVERAGE REALLY RAMPS UP BTWN NOW AND 4 PM...
DON'T PLAN ON RUNNING WITH A PRE-FIRST PERIOD AND WILL MENTION JUST
SCATTERED EVENING SHOWERS/STORMS.

FRIDAY...CWA REMAINS IN WSW MID LEVEL FLO PATTERN WITH POS TILT
TROUGH EXTENDING FROM THE SERN SEABOARD ACROSS NORTH FL AND INTO THE
ERN GOMEX. MEAN DRYING IS INDICATED BY BOTH THE NAM AND GFS WITH
PWATS DROPPING TO NEAR 1.25" NORTH AND 1.5 - 1.6" SOUTH. SHAVED POPS
BACK TO 30 AREAWIDE...AND WAS TEMPTED TO GO WITH SLIGHT CHANCE ACROSS
THE NORTH...BUT WILL LEAVE FOR NOW GIVEN ADJCT CWA FCSTS...MID SHIFT
CAN ADJUST AS NEEDED.

FRI NIGHT-SUN...THE BASE OF THE UPPER TROUGH SHIFTS SOUTH INTO THE
NORTH GULF OF MEXICO. AS IT DOES THE MOISTURE RIBBON IN THE DEEP
LAYER SOUTHWEST FLOW IS PUSHED OVER SOUTHERN FLORIDA AND THE FLORIDA
STRAIT. THE 17/12Z GFS AND THE 17/00Z ECMWF SHOW A DRY SLOT ROTATING
OVER THE PENINSULA OVER THE WEEKEND WHICH SHOULD LIMIT RAIN CHANCES
TO THE 30 TO 40 PERCENT RANGE. TIME HEIGHT CROSS SECTIONS SHOWING A
DROP IN THE MEAN LAYER MOISTURE OVERNIGHT FRIDAY AND CONTINUING
THROUGH THE WEEKEND HELPING TO VALIDATE LOWER RAIN CHANCES. MORNING
LOWS SAT AND SUN IN THE MID AND UPPER 60S TO LOWER 70S MARTIN COUNTY
BEACHES. HIGHS ON SAT IN THE MID 80S AT THE COAST THANKS TO A SEA
BREEZE AND THE UPPER 80S FOR THE INTERIOR. STAYS OVER THE SOUTHEAST
AND FLORIDA.

MON-WED...(PREVIOUS EXTENDED) STUBBORN MID LEVEL TROUGH FINALLY
DAMPENS OUT EARLY NEXT WEEK...BUT WSW MID LEVEL FLOW AND BELOW
NORMAL H50 HEIGHTS REMAIN OVERHEAD. FEEL AS THOUGH GFS PRES PATTERN
IS LIKELY CONTAMINATED BY SPURIOUS WEST CARIBBEAN LOW...AND WILL
LIKELY BE LOOKING AT WEAKER FLOW OUT OF THE SE OR SOUTH EARLY NEXT
WEEK. SEE NO REASON TO DEPART FROM CURRENT FCST OF LOW END SCT (30)
POPS EACH AFTERNOON. TEMPS REBOUND TO NEAR OR A DEGREE OR TWO ABOVE
CLIMO BY MID WEEK.

&&

.AVIATION...CLOUDS THINNED OUT AS FCST...WITH COVERAGE OF SHOWERS
SHOWING A SLOW INCREASE. ACTIVITY STILL EXPECTED TO INCREASE IN
COVERAGE/INTENSITY AFT 19Z WITH LOCAL IFR CIGS/VSBYS AND WIND GUSTS
OVER 35KT POSSIBLE THROUGH ABOUT 02Z-03Z.

&&

.MARINE...WHILE FLOW ON THE WEST SIDE OF THE ATLC RIDGE HAS BEEN
KEEPING WINDS S-SSW...LOCAL WIND REGIME WILL BECOME RATHER CHAOTIC
THE NEXT H24 AS SURFACE TROUGH SAGS INTO THE ADJCT ATLC. HOWEVER
SPEEDS REMAIN GENERALLY AOB 10KT WITH 2-4FT SEAS IN A LONG PERIOD
(10-12S) SWELL.

SAT-SUN...WEAK GRADIENT CONTINUES INTO THIS WEEKEND. WINDS BECOME
LIGHT ONSHORE AFTER FRI...WITH SPEEDS REMAINING 10 KT OR LESS. SWANS
BEEN A FOOT OR SO HIGH SO LIMITING SEAS TO 4 FEET OFFSHORE AND 2 TO
3 FEET NEARSHORE.

MON-TUE...SEAS MAY BUILD TO 4 TO 5 FEET AS A 2 FOOT LONG PERIOD
EASTERLY SWELL PROPAGATES INTO THE COASTAL WATERS.

&&

.FIRE WEATHER...NO SIGNIFICANT FIRE WEATHER CONCERNS AS MIN RELATIVE
HUMIDITY VALUES REMAIN IN THE 40S WITH LIGHT WIND PATTERN. REPEATED
GROUND/FUEL WETTING FROM RECENT RAINS OVER THE PAST COUPLE WEEKS HAS
DECREASED THE OVERALL FIRE DANGER FOR THE TIME BEING.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
A MID LEVEL DISTURBANCE WILL APPROACH THE STATE TODAY...WHICH IN
ADDITION TO THE MOIST ATMOSPHERE THAT REMAINS IN PLACE WILL LEAD
TO NUMEROUS SHOWERS AND STORMS DEVELOPING LATE THIS MORNING THROUGH
THE EVENING HOURS. ISOLATED SHOWERS AND A FEW STORMS WILL MOVE
FROM THE EASTERN GULF OF MEXICO INTO THE STATE EARLY THIS MORNING
WITH ACTIVITY INCREASING IN COVERAGE THROUGH THE DAY AS WARM
AFTERNOON TEMPERATURES INCREASE INSTABILITY. THE HIGHEST COVERAGE
OF SHOWERS AND STORMS IS EXPECTED TO BE ACROSS OKEECHOBEE AND THE
TREASURE COAST WHERE MOISTURE WILL REMAIN HIGHER.

STORMS ARE EXPECTED TO MOVE TO THE EAST-NORTHEAST AT AROUND 20
MPH...AND STORMS INTERACTING WITH THE EAST COAST SEA BREEZE MAY
ACQUIRE ROTATION AS THEY MOVE OVER THE COAST WITH FUNNEL CLOUDS OR
A BRIEF TOUCHDOWN POSSIBLE. COOLER TEMPERATURES ALOFT WILL ALSO
INCREASE THE CHANCES FOR SMALL HAIL IN ANY STRONG TO SEVERE STORMS
THAT DEVELOP. FREQUENT LIGHTNING STRIKES AND TORRENTIAL RAINFALL
WILL BE POSSIBLE WITH ANY ACTIVITY THAT DEVELOPS TODAY...WITH
TEMPORARY PONDING OF WATER ON ROADWAYS POSSIBLE ESPECIALLY IN
LOCATIONS THAT SAW HEAVY RAINFALL OVER THE PREVIOUS FEW DAYS.

.MARINE THUNDERSTORM GUST IMPACT...
ISOLATED SHOWERS AND STORMS WILL MOVE EASTWARDS FROM THE GULF OF
MEXICO THIS MORNING WITH ACTIVITY INCREASING IN COVERAGE BY LATE
MORNING AND THROUGH THE EVENING HOURS. STRONGER STORMS THAT
DEVELOP MAY PRODUCE WIND GUSTS IN EXCESS OF 35 KNOTS AND FREQUENT
LIGHTNING STRIKES ARE EXPECTED. STORMS WILL MOVE EAST-NORTHEAST
AT 20 KNOTS.

.FIRE WEATHER IMPACT...
THERE IS A LOW TO MODERATE ENVIRONMENTAL FIRE DANGER DUE TO DRY
FUELS. SOME RAIN WETTING IS EXPECTED THIS AFTERNOON...BUT LIGHTNING
STORMS COULD INITIATE NEW FIRES.

.RIP CURRENT IMPACT...
WEATHER AND OCEANIC CONDITIONS WILL PRODUCE A MODERATE RISK FOR
RIP CURRENTS AT AREA BEACHES TODAY. CHECK WITH THE BEACH PATROL
FOR ADDITIONAL INFORMATION...SWIM ONLY WITHIN SIGHT OF A LIFEGUARD
AND NEVER SWIM ALONE.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
SUFFICIENT MOISTURE WILL EXIST FOR SCATTERED STORMS THROUGH THIS
WEEKEND. LOW LEVEL FLOW WILL SHIFT OUT OF THE EAST STARTING THIS
WEEKEND SHIFTING THE HIGHEST COVERAGE OF SHOWERS AND STORMS
TOWARDS THE WEST SIDE OF THE STATE.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE IF
NEEDED.
