AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
344 PM EDT TUE APR 29 2014

.DISCUSSION...
CURRENT...LATEST KXMR 15Z CAPE SOUNDING SHOWS A PWAT OF 1.22 INCHES
DOWN FROM 1.41 INCHES FROM THE 10Z SOUNDING. THE ATMOSPHERE REMAINS
MODERATELY UNSTABLE. DEWPOINT VALUES ACROSS EAST CENTRAL FLORIDA
REMAIN RATHER SOUPY WITH LOWER 70 DEGREE READINGS. AFTERNOON
TEMPERATURES HAVE MADE IT INTO THE UPPER 80S TO AROUND 90 DEGREES AS
THE DEBRIS CLOUDS FROM CONVECTION OVER NORTH FLORIDA THIN OUT ACROSS
THE CENTRAL PENINSULA.

THE EAST/WEST COAST SEA BREEZE BOUNDARIES ARE MOVING INLAND THIS
AFTERNOON. THERE WILL BE A COLLISION BETWEEN THESE TWO FEATURES LATE
IN THE DAY AND ALONG WITH VARIOUS MESOSCALE BOUNDARY INTERACTIONS
WILL PROMOTE THE GREATEST CHANCES FOR CONVECTION INTO MID EVENING. A
MID-LEVEL TROUGH TRAVERSING THE AREA LATER WILL ALSO PROVIDE SOME
LIFT/FORCING IN THE ATMOSPHERE. PWAT VALUES WHILE LOW NOW ARE
FORECAST TO COME BACK UP TO AROUND 1.60 INCHES BY EARLY EVENING.
WILL GO WITH A PRE-FIRST PERIOD WORDING IN THE ZONES AND KEEP
SCATTERED POPS OVER MUCH OF THE AREA INTO THE EVENING. AFTER THE
CONVECTION DISSIPATES EXPECT CONSIDERABLY CLOUDY SKIES TO BECOME
PARTLY CLOUDY. LIKELY WILL SEE SOME AREAS OF STRATUS DEVELOPING
TOWARDS SUNRISE ACROSS THE AREA.

A FEW STORM CELLS THIS AFTERNOON AND EVENING WILL BE CAPABLE OF
FREQUENT CLOUD TO GROUND LIGHTNING...SMALL HAIL...TORRENTIAL
DOWNPOURS AND GUSTY DOWNBURST WINDS OF 45 TO 55 MPH. CELL MOVEMENT
WILL BE NNE/NE AT 10 TO 15 MPH.

BREEZY CONDITIONS HAVE DEVELOPED OVER THE SPACE AND TREASURE COASTS
WITH SUSTAINED EAST-SOUTHEAST WINDS AROUND 20 MPH WITH FREQUENT
HIGHER GUSTS. INLAND AREAS REMAIN WELL BELOW THESE BREEZY
CONDITIONS. WHILE WINDS WILL DECREASE THIS EVENING...WE WILL STILL
MAINTAIN AN ELEVATED SOUTHEASTERLY FLOW THAT WILL KEEP OVERNIGHT
LOWS IN THE LOWER 70S MOST PLACES.

WED...HIGH PRESSURE WILL BEGIN TO GET SHUNTED SOUTH AND EAST AS A
COOL FRONTAL BOUNDARY MOVES INTO THE FLORIDA PANHANDLE BY LATE IN
THE DAY. SOUTHEAST WINDS AGAIN WILL AVERAGE AROUND 15 MPH OVER THE
INTERIOR/VOLUSIA COAST WITH BREEZY CONDITIONS ALONG THE SPACE AND
TREASURE COASTS...15-20 MPH AND GUSTY. AFTERNOON RAIN CHANCES WILL
CENTER AROUND THE SEA BREEZE REGIME WITH LOW END CHANCE POPS AROUND
30 PERCENT INLAND FROM THE BREVARD AND TREASURE COASTS. ANOTHER WARM
DAY ON TAP WITH HIGHS AROUND 90 EXCEPT A FEW OF DEGREES COOLER AT
THE IMMEDIATE COAST.

THU...FRONT BEGINS TO MAKE ITS WAY THROUGH NORTH FLORIDA WITH
INCREASING SOUTH TO SOUTHWESTERLY WINDS OUT AHEAD OF IT. ANOTHER
HOT DAY OF INTERIOR TEMPERATURES AROUND 90 DEGREES WILL MEAN RAIN
AND STORMS WILL ONCE AGAIN BE MOSTLY ASSOCIATED WITH THE SEA
BREEZE. THE 12Z GFS BACKED OFF SOME ON POPS AND SHOW HIGHER
NUMBERS THU NIGHT. WITH THE BULK OF STORMS TIED TO DAYTIME
HEATING AND IN THE INTEREST OF CONTINUITY...WILL NOT CHANGE THE
POPS WE HAD IN THE PREVIOUS FORECAST...50 PERCENT IN THE NORTH AND
40 PERCENT FOR MOST OF THE REST OF THE AREA.

FRI-SAT (PREVIOUS DISCUSSION)...LOOKS LIKE THE FRONT WILL SPEND
THE DAY FRIDAY ACROSS CENTRAL FLORIDA FUNNELING MORE MOISTURE IN
ACROSS THE PENINSULA UNDER THE INFLUENCE OF DEEP SOUTHWEST FLOW.
AREAS NORTH OF THE FRONT WILL SEE A BREAK IN TEMPERATURES FRIDAY
WHICH RIGHT NOW LOOKS LIKE NORTH OF ORLANDO WITH HIGHS IN THE LOW
80S. EVEN A FEW DEGREES COOLER ELSEWHERE DUE TO FAIRLY EXTENSIVE
CLOUD COVER. THE FRONT FINALLY MAKES IT THROUGH EAST CENTRAL
FLORIDA SATURDAY WITH BEST RAIN CHANCES ASSOCIATED WITH THE FRONT
FROM ABOUT THE CAPE SOUTHWARD. RAIN TAPERS OFF BEHIND THE FRONT
SATURDAY NIGHT.

SUN-TUE...DRYING OUT SUNDAY. ECM WANTS TO DEVELOP A WEAK DISTURBANCE
IN THE EASTERN GULF SUNDAY AND SUNDAY NIGHT WHICH WOULD LINGER RAIN
CHANCES BUT HAVE STAYED CLOSER TO THE GFS WHICH HAS CONSISTENTLY
SHOWN HIGH PRESSURE MOVING IN ONCE THE FRONT FINALLY CLEARS THE
AREA. TEMPERATURES CLIMB AGAIN SUNDAY THROUGH TUESDAY INTO THE MID
TO UPPER 80S WHICH IS CLOSE TO NORMAL FOR THE INTERIOR BUT A FEW
DEGREES ABOVE NORMAL FOR THE COAST. EXPECT SEA BREEZE TO FORM EACH
AFTERNOON BUT NOT SPARK MANY SHOWERS DUE TO DRY AIR IN PLACE WITH
MODEL SOUNDINGS INDICATING PWAT VALUES LESS THAN 1 INCH.

&&

.AVIATION...LATEST KXMR SOUNDING NOT INDICATIVE OF VERY HIGH
COVERAGE OF SHRA/TSRA THIS AFTERNOON/EVENING...AS IT IS VERY DRY BUT
WILL STILL HOLD ONTO VCTS IN TAFS AND A FEW TEMPO GROUPS NORTHWARD
ACROSS ECFL. FEEL SOME ADDITIONAL DEEP LAYER MOISTURE AND MID-LEVEL
ENERGY WILL GET SHRA/TSRA GOING. CONVECTION THAT DOES DEVELOP WILL
WIND DOWN BY MID TO LATE EVENING. SHOULD SEE BREEZY SE WINDS AGAIN
WITH THE SEA BREEZE ON WED ALONG THE COAST FROM KMLB-KSUA WITH GUSTS
TO 22-26 KNOTS 18Z-00Z PSBL. MOS GUIDANCE HINTS AT SOME PATCHES OF
MVFR-IFR LOW CLOUDS POSSIBLE LATE OVERNIGHT AND EARLY WED MORNING.
OVERALL WEATHER PATTERN FOR WED LOOKS SIMILAR TO TODAY...BUT WITH
SLIGHTLY INCREASING CELL COVERAGE.

&&

.MARINE...REMAINDER OF AFTERNOON-TONIGHT...SSE WINDS AROUND 15 KTS
INCREASING TO 15-18 KTS FOR OFFSHORE WATERS THIS EVENING THROUGH
MUCH OF THE OVERNIGHT. CAUTIONARY STATEMENTS FOR WINDS NECESSARY
THIS EVENING NORTH OF SEBASTIAN INLET OFFSHORE. SEAS MAINLY 3-4 FT
BUT THERE MAY BE SOME 5 FT SEAS NORTH OF THE CAPE LATE TONIGHT. A
FEW LIGHTNING STORMS THIS EVENING WILL MOVE OFF OF THE
BREVARD-VOLUSIA COASTS AND ACROSS THE INTRACOASTAL/NEAR SHORE WATERS.

WED...SE WINDS WILL BACK DOWN SLIGHTLY EARLY ON THIS DAY BUT ARE
FORECAST TO INCREASE AGAIN TO 15-18 KTS IN THE AFTERNOON. SEAS 3-4
FT NEAR SHORE AND 4 FT OFFSHORE...EXCEPT SOME 5 FT SEAS NORTH OF THE
CAPE WELL OFFSHORE. A FEW OFFSHORE MOVING STORMS POSSIBLE AGAIN LATE
ON THIS DAY.

THU-FRI...FRONTAL BOUNDARY WILL REMAIN NORTH OF THE AREA THU
WHICH MEANS WINDS WILL STAY SOUTHERLY...WITH SPEEDS AROUND 15
KNOTS. THE FRONT SHOULD SLIDE INTO THE NORTHERN WATERS FRI WHICH
WOULD TURN WINDS LIGHT THERE...BUT SOUTHERLY FLOW AT 10 TO 15
KNOTS SHOULD CONTINUE FROM CANAVERAL SOUTH. SOUTHWEST STEERING
LEVEL FLOW WILL BRING A CHANCE OF STORMS ACROSS THE COAST DURING
THE PERIOD ESPECIALLY IN THE AFTERNOON/EVENING.

SAT-SUN...SLOW MOVING FRONT IS INDICATED ACROSS THE WATERS SAT.
NORTH WINDS MIGHT REACH 15 KNOTS NORTH OF CANAVERAL BEHIND IT WITH
10-15 KNOT SOUTHERLY FLOW ACROSS THE SOUTH. THE FRONT IS FINALLY
FORECAST TO SHIFT AWAY FROM THE WATERS ON SUNDAY WITH NORTH WINDS
15-20 KNOTS POSSIBLE ESPECIALLY IN THE GULF STREAM. QUITE HIGH
SHOWER AND STORM CHANCES ARE INDICATED SAT THEN ONLY A SMALL
CHANCE APPEARS POSSIBLE IN THE SOUTH SUNDAY MORNING.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
DAYTIME HEATING...INCREASING MOISTURE LEVELS AND DEVELOPING SEA

GUSTS TO 45 TO 50 MPH...FREQUENT LIGHTNING...SMALL HAIL...AND
LOCALLY HEAVY RAINFALL AMOUNTS OF ONE TO TWO INCHES. ISOLATED

LONG PERIOD NORTHEAST OCEAN SWELLS WILL CONTRIBUTE TO A MODERATE
RISK OF RIP CURRENTS AT EAST CENTRAL FLORIDA BEACHES TODAY. ALWAYS
SWIM NEAR A LIFEGUARD AND NEVER SWIM ALONE. THE RISK WILL BE
HIGHEST AROUND THE TIME OF LOW TIDE FROM EARLY TO MID AFTERNOON.

.MARINE THUNDERSTORM GUST IMPACT...
A FEW STORMS MAY PRODUCE GUSTY WIND IN EXCESS OF 35 KNOTS ACROSS
THE INLAND LAKE AND INTRACOASTAL AND NEAR SHORE ATLANTIC WATERS
NORTH OF SEBASTIAN INLET.

.WIND AND SEA IMPACT...
SOUTHERLY WINDS TO 15 TO 20 KNOT ACROSS THE OFFSHORE WATERS
TONIGHT WILL BUILD SEAS TO 4 TO 5 FEET OFFSHORE.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
SCATTERED THUNDERSTORMS ARE EXPECTED WEDNESDAY AND THURSDAY AHEAD
OF AN APPROACHING COLD FRONT THAT WILL AFFECT THE AREA FRIDAY
INTO SATURDAY AS THE FRONT MOVES SLOWLY THROUGH EAST CENTRAL
