AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
316 AM EST SUN DEC 2 2012
.DISCUSSION...
TODAY...
DEEP/PERSISTENT E/NERLY FLOW ACRS CENTRAL FL WILL BE MAINTAINED BY A
STUBBORN HIGH PRES RIDGE EXTENDING FROM THE NC OUTER BANKS TO THE
WRN GOMEX. LATEST RAP ANALYSIS SHOWS PLENTY OF LOW LVL MOISTURE
UPSTREAM...A FINGER OF H100-H70 MOISTURE NOTED JUST E OF THE BAHAMA
BANK WITH MEAN RH VALUES BTWN 70-80PCT.
EMBEDDED WITHIN THE DEEP ERLY FLOW...THIS MOISTURE WILL PUSH INTO
THE FL PENINSULA AFT DAYBREAK AND SHOULD PROVIDE THE FUEL NECESSARY
FOR ISOLD/SCT SHRAS FOR MOST OF THE CWA. COVERAGE HIGHEST ALONG THE
COAST S OF CAPE CANAVERAL GIVEN THE RAP MOISTURE PROFILE. IMPACT
WILL BE LOW...HOWEVER...AS THE RIDGE AXIS MAINTAINS A SHARP
SUBSIDENCE INVERSION IN THE H85-H70 LYR. THIS WILL LIMIT VERTICAL
MOTION BLO 10KFT...QPF BLO 0.10" AREAWIDE. NO CHANGE IN THE SOURCE
REGION...LITTLE CHANGE IN TEMP DISTRIBUTION FROM SAT. ONSHORE FLOW
WILL KEEP MAX TEMPS A FEW DEGS COOLER ALONG THE COAST...BUT AFTN
READINGS WILL BE BTWN 75-80F AREAWIDE.
TONIGHT...
THE RIDGE AXIS WILL DRIFT SWD AS A STORM SYSTEM MOVING OUT OF THE
NRN ROCKIES RIDES UP ITS BACKSIDE. THE ERLY FLOW WILL DIMINISH AS A
RESULT BUT SHOULD HOLD UP ENOUGH TO PREVENT DECOUPLING. MIN TEMPS IN
THE M/U50S INTERIOR...L/M60S ALONG THE COAST.
SLIGHTLY DRIER AIR NOTED BEHIND THE AFOREMENTIONED MOISTURE POCKET
WITH H100-H70 MEAN RH VALUES FALLING BLO 70PCT. DIFFICULT TO SQUEEZE
MEASURABLE PRECIP OUT OF SUCH AN AIRMASS OUTSIDE OF THE GULF STREAM.
WILL KEEP PRECIP OUT OF THE FCST...KEEPING A SILENT 10PCT FOR THE
COASTAL COUNTIES.
MON-TUE...SURFACE HIGH PRESSURE RIDGE AXIS WILL CONTINUE VICINITY
GEORGIA AND NORTH FLORIDA. THIS WILL MAINTAIN AN ONSHORE WIND FLOW...
THOUGH IT WILL BE A LITTLE WEAKER AS THE LOCAL PRESSURE GRADIENT
SLOWLY EASES. THIS ONSHORE FLOW WILL TAP SUBSIDENT/DRIER AIR OVER
THE ATLANTIC SO EXPECT NEGLIGIBLE POPS MON. THE GFS SHOWS LIGHT
PRECIP OVER THE ATLANTIC ON TUE BUT MOS POPS ARE ONLY 5 PERCENT SO
WILL MAINTAIN A DRY FORECAST. MILD TEMPS WITH HIGHS MOSTLY IN THE
UPPER 70S AND LOWS IN THE MID-UPPER 50S INLAND AND LOWER 60S ALONG
THE COAST.
WED-SUN...THE HIGH PRESSURE RIDGE WILL BREAK DOWN ON WED AS A
FRONTAL BOUNDARY PUSHES OFFSHORE THE EASTERN SEABOARD WITH
TRAILING SOUTHERN PORTION HANGING UP TO OUR NORTH. SOUTHERN
PORTION OF A SHORTWAVE TROUGH IS PROGGED TO CROSS THE REGION WED
NIGHT BUT GFS CONTINUES TO SHOW THAT THE AVAILABLE MOISTURE WILL
BE LIMITED. THE ECMWF IS A LITTLE MORE MOIST...BUT STILL THE BULK
OF PRECIP IS INDICATED OVER THE ATLANTIC. THEREFORE...HAVE
MAINTAINED PREVIOUS FORECAST...WHICH CONFINES SMALL POPS TO THE
COASTAL WATERS.
STRONGER HIGH PRESSURE WILL REBUILD ALONG THE EASTERN SEABOARD THU
AND CAUSE ONSHORE FLOW TO INCREASE A LITTLE. THE FLOW IS PROGGED
TO WEAKEN BY NEXT WEEKEND AS THE RIDGE AXIS SHIFTS CLOSER TO THE
AREA. ANY RAIN CHANCES IN THIS PATTERN WILL BE SMALL. THE 00Z GFS
SHOWS SLIGHTLY HIGHER MOISTURE AND LIGHT QPF ON FRI SO HAVE
INCLUDED A SMALL POP FOR THE SOUTH HALF OF THE COAST. A LITTLE
MORE MOISTURE POOLING INDICATED SAT/SUN AHEAD OF A WEAK UPPER
LEVEL IMPULSE...BUT HAVE ONLY CARRIED A SMALL POP ALONG THE NORTH
HALF OF THE COAST ON SAT.
LITTLE CHANGE IN THE MILD TEMPERATURES IS INDICATED THROUGH THE
PERIOD.

SLIGHTLY WEAKER N OF CAPE CANAVERAL DUE TO WEAKER PGRAD. LITTLE
IMPROVEMENT THRU TONIGHT AS A HI PRES RIDGE EXTENDING FROM THE NC
OUTER BANKS TO THE WRN GOMEX MAINTAINS A FAIRLY TIGHT PGRAD ACRS THE
LCL ATLC. ROUGH SEAS AREAWIDE AS A 15-25KT E/NE FETCH BTWN BERMUDA
AND THE BAHAMA BANK PUSHES A MODERATE SWELL INTO THE E FL COAST.
WILL HOIST AN SCA FOR ALL LCL WATERS THRU SUNSET...SCALING BACK TO
THE OFFSHORE WATERS OVERNIGHT AS THE RIDGE SAGS SLOWLY SWD ALLOWING
THE PGRAD TO SLACKEN.
