AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
305 PM EDT TUE OCT 14 2014

.DISCUSSION...

THRU TONIGHT...LATE MORNING CAPE SOUNDING SHOWS AIRMASS CONTINUING
TO MOISTEN IN INCREASING SOUTHERLY FLOW. RESIDUAL DRY AIR IS SEEN
IN THE MID LEVELS BETWEEN 500 AND 600 MB AND THIS WILL PROMOTE A
THREAT FOR STRONG DOWNBURST WINDS IN STORMS INTO THIS EVENING.
SCATTERED SHOWERS AND STORMS WILL INCREASE IN COVERAGE THROUGH THE
AFTN AIDED BY INCREASING LOW LEVEL CONVERGENCE FROM DIFFUSE SEA
BREEZE BOUNDARIES AND SFC HEATING. THE FOCUS WILL BE ON THE EAST
SIDE OF THE PENINSULA WITH SCATTERED STORMS CONGEALING INTO A
PRIMARY BAND THAT PUSHES OFFSHORE AROUND OR SHORTLY AFTER SUNSET.
JET FORCED ASCENT IS SUPPORTING PRE FRONTAL SQUALL LINE (JUST
AHEAD OF THE COLD FRONT) OVER THE EASTERN GULF AND THIS WILL
OVERSPREAD CENTRAL FL TONIGHT. WILL NEED TO KEEP RAIN CHANCES
ACROSS NORTH HALF OVERNIGHT BUT EXPECT THE LINE TO WEAKEN AND DO
NOT EXPECT SEVERE STORMS OVERNIGHT.

WED-WED NIGHT...A COLD FRONT WILL SWEEP ACROSS FLORIDA DURING THE
DAY AND IS FORECAST TO CLEAR CENTRAL FLORIDA OVERNIGHT. BRISK SOUTH
TO SOUTHWEST FLOW AHEAD OF THE FRONT PULLS CARIBBEAN AND GULF OF
MEXICO MOISTURE INTO CENTRAL FLORIDA WITH PRECIPITABLE WATER VALUES
OF 2 OR MORE INCHES WED MORNING THEN QUICKLY DROPPING OFF WITH
FRONTAL PASSAGE. ALTHOUGH MOST OF THE MID AND UPPER LEVEL SUPPORT
OF STRONG POSITIVE VORTICITY ADVECTION AND UPPER LEVEL JET
DIVERGENCE ARE WELL NORTH OF CENTRAL FLORIDA...THERE LOOKS TO BE
ENOUGH TO GO WITH A 50 PERCENT OF SHOWERS AND STORMS. SOUTHWEST
STEERING WINDS OF 20 MPH WILL HELP TO PUSH THE SHOWERS AND
ISOLATED STORMS OFF TO THE EAST AT 15 TO 20 MPH. EVEN THOUGH SOME
STORMS MAY HAVE THE ABILITY TO PRODUCE LOCALLY HEAVY RAIN...STORM
MOTION AT 15 TO 20 MPH SHOULD LIMIT SIGNIFICANT ACCUMULATIONS.
HIGHS EXPECTED TO RANGE FROM THE MID 80S NORTHERN AREAS TO THE
UPPER 80S IN THE CENTRAL AREAS TO AROUND 90 IN OKEECHOBEE.
THURSDAY MORNING LOWS FROM THE LOWER 60S ALONG AND NORTH OF
INTERSTATE 4 TO THE MID 60S TO THE SOUTH.

THU (PREVIOUS)...DRIER AIR MASS BEHIND THE FRONT BRINGS A MORE
COMFORTABLE DAY WITH HIGHS IN THE LOW 80S NORTH OF INTERSTATE 4
AND THE MID 80S OVER CENTRAL AND SOUTHERN FLORIDA. RELATIVE
HUMIDITY VALUES BOTTOM OUT IN THE 40S NORTH OF INTERSTATE 4 AND
THE 50S DOWN INTO SOUTH SAINT LUCIE AND MARTIN COUNTIES WHERE THE
MIN RELATIVE IS AROUND 60 PERCENT.

FRI-MON (PREVIOUS)...UPPER LOW LIFTS NORTH INTO THE GREAT LAKES
AREA. DRIER AIR MASS LIMITS RAIN CHANCES TO AROUND 10 PERCENT OR
LESS EACH DAY. HIGH PRESSURE TAKES UP RESIDENCE OVER THE GULF
COAST AND THE GULF OF MEXICO. THE RIDGE AXIS EXTENDS ACROSS
CENTRAL FLORIDA AND INTO THE ATLANTIC NORTH OF GRAND BAHAMA
ISLANDS. LIGHT NORTH TO NORTHWEST WINDS WITH HIGHS IN THE LOW TO
MID 80S.

&&

.AVIATION...
SCATTERED TO NUMEROUS STORMS WILL SPREAD TOWARD THE NE AND AFFECT
MOST TERMINALS SO HAVE MAINTAINED TEMPO GROUPS THROUGH ABOUT 00Z
THEN VCSH THOUGH A PERIOD OF PREVAILING RA IS LIKELY MCO NORTH.
FRONT FORECAST TO PUSH ACROSS TERMINALS WED WITH SCT TSRA
REDEVELOPING AHEAD OF THE FRONT MAINLY MCO SOUTH.

&&

.MARINE...
TONIGHT...SOUTH WINDS 15-20 KNOTS OVER THE NORTH AND CENTRAL
WATERS WILL REQUIRE A CAUTION STATEMENT BUT SEAS SHOULD REMAIN
AROUND 5 FT. SCATTERED TO NUMEROUS STORMS WILL PUSH OFFSHORE THIS
EVENING FROM THE EAST COAST.

WED-SAT...FRONTAL BOUNDARY PUSHES ACROSS THE COASTAL WATERS WED
WITH S/SW WINDS SHIFTING TO THE W/NW INTO WED NIGHT. WINDS SPEEDS
FORECAST TO BRIEFLY INCREASE TO 15 TO 20 KNOTS BEHIND THE BOUNDARY
INTO THE OVERNIGHT HOURS OF WED INTO THU WITH SEAS BUILDING UP TO
6 FEET OFFSHORE. SEAS 3 TO 5 FEET WED REACH 6 TO 8 FEET WELL
OFFSHORE THURSDAY AND FRIDAY DUE TO A LONG PERIOD SWELL FROM
TROPICAL CYCLONE GONZALO WELL EAST OF CENTRAL FLORIDA.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
SHOWERS AND STORMS WILL INCREASE IN COVERAGE THIS AFTERNOON
ACROSS THE INTERIOR AND ALONG THE INLAND MOVING EAST COAST SEA
BREEZE. GREATEST COVERAGE OF STORMS WILL OCCUR OVER THE INTERIOR
LATE THIS AFTERNOON WITH ANY BOUNDARY COLLISIONS THAT OCCUR.
CONVECTION THAT RESULTS FROM THIS COLLISION WILL THEN PUSH
NORTHEAST BACK TOWARD THE COAST INTO THE EVENING HOURS. A FEW
STORMS COULD BECOME STRONG TO SEVERE NEAR AND NORTH OF INTERSTATE
4 WITH STRONG WIND GUSTS IN EXCESS OF 50 MPH...FREQUENT LIGHTNING
AND SMALL HAIL. TORRENTIAL RAINFALL AMOUNTS UP TO 2 TO 3 INCHES IN
A 60 TO 90 MINUTE PERIOD COULD PRODUCE LOCALIZED TEMPORARY URBAN
OR ROAD FLOODING AND PONDING OF WATER IN POORLY DRAINED LOW LYING
AREAS.

STORMS WILL MOVE TOWARD THE NORTHEAST AT 15 TO 20 MPH EARLY THIS
AFTERNOON...WITH STORM MOTION AS HIGH AS 25 TO 30 MPH TO THE NORTH
OF ORLANDO AND TITUSVILLE FROM LATE THIS AFTERNOON INTO THE EARLY
EVENING.

KEEP ABREAST OF WEATHER CONDITIONS TODAY...AND MOVE INDOORS TO
SAFETY IN ADVANCE OF THREATENING WEATHER.

.MARINE THUNDERSTORM GUST IMPACT...
STORMS WILL ALSO BE CAPABLE OF PRODUCING STRONG WIND GUSTS IN
EXCESS OF 35 KNOTS OVER INLAND LAKES...THE INTRACOASTAL AND NEAR
SHORE ATLANTIC WATERS. BOATERS SHOULD BE AWARE OF THE THREAT FOR
STRONG STORMS APPROACHING RAPIDLY FORM THE SOUTHWEST LATER TODAY.

.RIP CURRENT IMPACT...
WEATHER AND OCEAN CONDITIONS WILL ONCE AGAIN PRODUCE A MODERATE
THREAT FOR RIP CURRENTS AT AREA BEACHES TODAY. THE THREAT WILL BE
HIGHEST FROM LATE AFTERNOON THROUGH SUNSET...DUE TO TIDAL EFFECTS.
CHECK WITH YOUR LOCAL BEACH PATROL ABOUT OCEAN HAZARDS WHEN YOU
ARRIVE AT THE BEACH. ALWAYS SWIM WITHIN SIGHT OF A LIFEGUARD AND
NEVER SWIM ALONE.

.WIND AND SEA IMPACT...
SOUTHERLY WINDS AROUND 15 TO 20 KNOTS WILL OCCUR ACROSS THE
OFFSHORE WATERS OF VOLUSIA COUNTY THROUGH THIS AFTERNOON AND
TONIGHT. OPERATORS OF SMALL CRAFT SHOULD EXERCISE CAUTION IF
VENTURING INTO THESE WATERS.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
BOATING CONDITIONS WILL BECOME HAZARDOUS ONCE AGAIN BY THURSDAY
AS LARGE SWELLS FROM DISTANT HURRICANE GONZALO START TO PROPAGATE
INTO THE LOCAL ATLANTIC WATERS. THIS WILL ALSO SIGNIFICANTLY
INCREASE THE THREAT FOR RIP CURRENTS AT AREA BEACHES.

THE SAINT JOHNS RIVER AT ASTOR AND NEAR GENEVA HAS DROPPED BELOW
ACTION STAGE. THERE IS THE CHANCE THAT THE COMBINATION OF LOCALLY
HEAVY RAINFALL...NORTHERLY WINDS AND TIDAL EFFECTS COULD CAUSE THE
RIVER TO TEMPORARILY RISE BACK UP TO ACTION STAGE AT ASTOR FROM
WEDNESDAY NIGHT INTO THURSDAY.

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