AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
11 AM EST SAT DEC 18 2010

.DISCUSSION...

LARGE REA OF RAIN WITH EMBEDDED HEAVY SHOWERS WILL CONTINUE TO
OVERSPREAD THE AREA AHEAD OF SFC LOW APPROACHING FROM THE GULF OF
MEXICO AND ASSOCIATED COLD FRONT. HAVE ADDED THUNDER TO THE TREASURE
COAST AND OKEECHOBEE COUNTY AS SOUTHERLY FLOW IS ADVECTING IN HIGHER
DEWPOINT AIR (MID 60S) AND MAX TEMPS SHOULD REACH THE UPPER 70S SO
THERE WILL BE HIGHER INSTABILITY THAN FARTHER NORTH. PRIMARILY
WATCHING A BAND OF HEAVY RAIN AND STORMS MOVING ONSHORE THE SW FL
COAST. THIS COULD AFFECT PORTIONS OF MARTIN AND SAINT LUCIE COUNTY
LATER THIS AFTERNOON AND BRING A THREAT FOR A STRONG STORM. WILL
ALSO BE WATCHING FOR INDIVIDUAL CELLS THAT DEVELOP NEAR THE TREASURE
COAST AS SFC WINDS ARE BACKED PRODUCING LOW LEVEL SHEAR (HELICITY)
WHICH COULD SUPPORT ROTATING STORMS.

HAVE UPDATED HWO TO INCLUDE A VERY LOW THREAT FOR TORNADO AND SEVERE
WINDS.

BACK EDGE OF RAIN SHIELD HAS PUSHED ONSHORE THE WEST COAST OF FL SO
SHOULD SEE DECREASING COVERAGE OF RAIN/SHOWERS LATE IN THE DAY FROM
WEST TO EAST.

&&

.AVIATION...
ALL TERMINALS UNDER BKN-OVC MULTI-LAYERED CLOUD DECK. EXPECT
PREVAILING VFR OUTSIDE OF RAIN SHIELD...WITH MVFR CIGS/VSBYS INSIDE
CLOUDS AND PRECIP. CIGS EXPECTED TO LWR FURTHER AFT 00Z INVOF THE
FRONTAL BDRY WITH AREAS OF BKN IFR CIGS IN THE FL005-010 RANGE PSBL.

&&

.MARINE...
SFC LOW WILL MOVE EAST ACROSS THE WATERS NEXT 12 HOURS WHICH WILL
PRODUCE SHIFTING WINDS BUT SPEEDS WILL REMAIN AT OR BELOW 15 KNOTS
THIS AFTN. SEAS 1-3 FT.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

...THUNDERSTORM IMPACT...
AS EXPECTED...A LARGE AREA OF RAIN WITH EMBEDDED HEAVIER SHOWERS
HAS DEVELOPED AHEAD OF AN APPROACHING SURFACE LOW AND ASSOCIATED
COLD FRONT. INCREASING LOW LEVEL MOISTURE FROM THE SOUTH COMBINED
WITH SOME SURFACE HEATING ACROSS SOUTHERN SECTIONS MAY GENERATE
ISOLATED LIGHTNING STORMS THIS AFTERNOON. ENHANCED LOW LEVEL SHEAR
MAY DEVELOP ALONG THE TREASURE COAST OF MARTIN...SAINT LUCIE AND
INDIAN RIVER COUNTIES WHICH WOULD INCREASE THE PROSPECT FOR STORMS
TO ROTATE.

...MARINE THUNDERSTORM GUST IMPACT...
ISOLATED LIGHTNING STORMS WILL BE CAPABLE OF PRODUCING STRONG WIND
GUSTS OF 35 KNOTS OR GREATER. STORM MOTION WILL BE TOWARD THE
NORTH OR NORTHEAST AROUND 20 MPH.

...WATERSPOUT IMPACT...
STORMS THAT DEVELOP OR MOVE OVER THE ATLANTIC AND INTRACOASTAL
WATERS MAINLY SOUTH AND EAST OF THE CAPE WILL BE CAPABLE OF
ROTATION.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
INCREASING WINDS AND SEAS ARE EXPECTED TO DEVELOP BEHIND THE COLD
FRONT EARLY SUNDAY MORNING...BRINGING DETERIORATING BOATING
CONDITIONS TO THE ATLANTIC WATERS. NORTHWEST TO NORTH WINDS OF
20 KNOTS WILL CAUSE SEAS TO BUILD TO AROUND 7 FEET WELL OFFSHORE
LATE SUNDAY AND SUNDAY NIGHT.

MARGINALLY LOW RELATIVE HUMIDITY VALUES ARE FORECAST TO OCCUR OVER
THE INTERIOR COUNTIES FROM LAKE AND INLAND VOLUSIA SOUTHWARD
THROUGH OSCEOLA ON MONDAY AFTERNOON.
