Area forecast discussion, Jul 5, 3:33 PM EDT, 1 hour 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
333 PM EDT SAT JUL 5 2014

.DISCUSSION...
REST OF THIS AFTERNOON-TONIGHT...WEST COAST CONVECTION HAS BEEN
PROGRESSING SLOWLY INLAND AND SCATTERED EAST COAST SEA BREEZE
STORMS WERE PUSHING A BOUNDARY WELL INLAND. THIS WILL LEAD TO AN
INCREASE IN COVERAGE/INTENSITY OF STORMS THROUGH LATE AFTERNOON
AND EARLY EVENING OVER THE INTERIOR. THERE IS A CHANCE FOR SOME
PUSH BACK TO THE EAST COAST OF THAT CONVECTION SO WILL CARRY
CHANCE POPS THROUGH LATE EVENING.

SUNDAY...OLD TROUGH TO OUR NORTH WILL CONTINUE TO WEAKEN AND THE
AXIS OF THE ATLANTIC SURFACE RIDGE SHOULD CONTINUE NEAR LAKE
OKEECHOBEE. THE GFS SHOWS A WEAK UPPER LEVEL TROUGH APPROACHING
WITH DEVELOPING DIVERGENCE ALOFT. MOISTURE VALUES SHOULD START OFF
1.9 TO 2.0 INCHES OF PRECIPITABLE WATER. 500 MB TEMPS ARE FORECAST
TO COOL TO ABOUT MINUS 8.5 DEGREES CELSIUS. MOS POPS RISE TO
AROUND 60 PERCENT AND HAVE FOLLOWED CLOSELY TO THOSE NUMBERS. IT
LOOKS LIKE ANOTHER ACTIVE AFTERNOON WITH FREQUENT LIGHTNING
STRIKES CONTINUING TO BE THE MAIN THREAT.

MON-FRI (PREVIOUS DISCUSSION)...GFS/ECMWF IN GOOD AGREEMENT
SHOWING SUBTROPICAL RIDGE WILL BE THE DOMINATING WEATHER FEATURE
INTO NEXT WEEK WITH SFC RIDGE AXIS PERSISTING ACROSS CENTRAL
FLORIDA. SOME DAY TO DAY DIFFERENCES IN MOISTURE OBSERVED IN THE
MODELS THROUGH NEXT WEEK BUT STILL HIGH ENOUGH TO MAINTAIN VERY
TYPICAL 30-50 PERCENT RAIN CHANCES IN THE FORECAST. SEA BREEZE
WILL DEVELOP AND MOVE INLAND EACH DAY WITH HIGHEST RAIN CHANCES
OCCURRING WITH BOUNDARY COLLISIONS OVER THE INTERIOR. LITTLE
CHANGE IN MAX TEMPS DAY TO DAY WITH NEAR 90F COAST AND LOW TO MID
90S INTERIOR.

&&

.AVIATION...PLENTY OF BOUNDARY INTERACTIONS WILL BRING A CHANCE
FOR IFR/MVFR WITH FREQUENT LIGHTNING TO MANY TERMINALS THROUGH
LATE AFTERNOON OR EARLY EVENING. THE GREATEST CHANCE SHOULD BE FOR
THE NORTHERN TERMINALS BUT CANNOT RULE OUT DEVELOPMENT FROM KMLB
TO KSUA EITHER. AFTER SUNSET VFR IS EXPECTED.

SUNDAY LOOKS VERY MOIST AGAIN AND EXPECT CONVECTION TO BE ACTIVE.
DID NOT INCLUDE ANY MENTION IN THE TAFS YET BUT SOME
SHOWERS/STORMS ARE POSSIBLE BEFORE 18Z ESPECIALLY KMLB TO KSUA
ALONG THE SEA BREEZE.

&&

.MARINE...
REST OF THIS AFTERNOON/TONIGHT...SCATTERED STORMS ASSOCIATED WITH
THE EAST COAST SEA BREEZE WILL AFFECT THE COAST AND NEARSHORE
ATLANTIC THROUGH LATE AFTERNOON. SOME STORMS SHOULD ALSO OCCUR
OVERNIGHT ESPECIALLY ALONG THE GULF STREAM. OUTSIDE THE SHOWERS
AND STORMS...BOATING CONDITIONS WILL BE FAVORABLE WITH SOUTH WINDS
10 KNOTS OR LESS.

SUN-THU (PREVIOUS DISCUSSION)...HIGH PRESSURE RIDGE AXIS WILL
GRADUALLY SHIFT NORTHWARD INTO CENTRAL FL AND PERSIST OVER THE
REGION. THIS WILL PRODUCE FAVORABLE BOATING CONDITIONS WITH THE
BEST CHANCE FOR STORMS INCREASINGLY STAYING OVER LAND. NOCTURNAL
INCREASES IN THE SOUTHERLY FLOW AROUND 15 KNOTS WILL BE POSSIBLE
OFFSHORE. OTHERWISE...SEA BREEZES EACH DAY WILL PRODUCE E/SE WINDS
10-12 KNOTS EACH AFTN NEAR THE COAST. SEAS WILL RANGE BETWEEN 1-2
FEET NEARSHORE AND 2-3 FEET OFFSHORE.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
DEEP MOISTURE WILL PERSIST ACROSS THE AREA TODAY AND WILL LEAD TO
THE DEVELOPMENT OF SCATTERED SHOWERS AND LIGHTNING STORMS INTO THE
AFTERNOON. THUNDERSTORMS WILL INITIALLY OCCUR ALONG THE COAST AS
THE SEA BREEZE FORMS AROUND NOON AND THEN CONVECTION WILL INCREASE
IN COVERAGE OVER THE INTERIOR AS SEA BREEZE AND OUTFLOW BOUNDARIES
MOVE INLAND. A FEW STRONGER STORMS WILL BE POSSIBLE WITH THE MAIN
THREATS BEING FREQUENT CLOUD TO GROUND LIGHTNING...STRONG WIND
GUSTS UP TO 50 MPH...SMALL HAIL AND LOCALLY HEAVY RAINFALL OF 2 TO
3 INCHES. STORMS WILL MOVE TOWARD THE NORTHEAST AROUND 10 TO 15
MPH.

.RIP CURRENT IMPACT...
OCEAN CONDITIONS WILL GENERATE A MODERATE RISK OF RIP CURRENTS
ALONG AREA BEACHES TODAY. IF CAUGHT IN A RIP CURRENT...SWIM
PARALLEL TO THE BEACH UNTIL OUT OF THE PULL OF THE CURRENT...AND
THEN SWIM BACK TO SHORE. ALWAYS SWIM WITHIN SIGHT OF A LIFE GUARD
AND DO NOT SWIM ALONE.

.MARINE THUNDERSTORM GUST IMPACT...
SCATTERED STORMS WILL DEVELOP ACROSS THE REGION THIS AFTERNOON AND
A FEW WILL HAVE THE POTENTIAL TO PRODUCE WINDS OF 35 KNOTS OR
GREATER. STORMS WILL INITIALLY DEVELOP ALONG THE COAST INTO EARLY
AFTERNOON AND WILL BE ABLE TO MOVE OFFSHORE AS THEY MOVE NORTHEAST
AROUND 10 TO 15 MPH. CONVECTION WILL THEN INCREASE OVER THE
INTERIOR INTO MID TO LATE AFTERNOON.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
SUFFICIENT MOISTURE AND INSTABILITY WILL EXIST ACROSS THE AREA
FOR SCATTERED AFTERNOON THUNDERSTORM DEVELOPMENT OVER THE NEXT
SEVERAL DAYS. A FEW STRONGER STORMS WILL BE POSSIBLE EACH
AFTERNOON...WITH GREATER STORM CHANCES TRANSITIONING TO THE
INTERIOR TOMORROW AND THROUGH MUCH OF NEXT WEEK.

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