AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
355 AM EST SAT FEB 18 2012

.DISCUSSION...

CURRENT...A WEAK PRESSURE GRADIENT OVER THE AREA HAS ALLOWED FOR
VERY LIGHT WINDS AT AND ABOVE THE SURFACE. A MIXTURE OF FOG (LOCALLY
DENSE IN SPOTS) AND LOW CLOUDS (STRATUS) WILL BE THE RULE PAST
SUNRISE AND PERHAPS INTO MID MORNING IN PLACES AS THE LOW-LEVELS
REMAIN FAIRLY SATURATED. HAVE RAISED A DENSE FOG ADVISORY FOR THE
INTERIOR SECTIONS THROUGH 9 AM WHERE SURFACE OBS AND REPORTS FROM
THE FLORIDA HIGHWAY PATROL INDICATE DENSE FOG HAS BECOME MORE
SPATIALLY EXTENSIVE...INCLUDING ALONG THE FLORIDA TURNPIKE IN
ORANGE/OSCEOLA AND SR429 IN ORANGE CO.

TODAY-TONIGHT...WEAK QUASI-STATIONARY FRONTAL BOUNDARY REMAINS
DRAPED ACROSS EAST CENTRAL FLORIDA EARLY THIS MORNING. WEAK HIGH
PRESSURE RIDGING WILL REMAIN SHUNTED SOUTH AND EAST OF THE AREA
KEEPING THE PRESSURE GRADIENT VERY WEAK OVER THE AREA. WINDS OF
VARYING DIRECTION AT TIMES DURING THE DAY WILL AVERAGE UNDER 10 MPH.
GREATER CHANCES FOR LIGHT SOUTHWEST WINDS OVER THE INTERIOR WITH A
WEAK ONSHORE COMPONENT EVENTUALLY DEVELOPING NEAR THE EAST COAST. A
WEAK EAST COAST SEA BREEZE IS FORECAST TO DEVELOP (WRF_ARW9 MODEL)
THIS AFTERNOON WITH SLOW INLAND PENETRATION LATE IN THE DAY AND
PERHAPS EVENTUAL COLLISION WITH ITS WEST COAST COUNTERPART. WITH
POOLING DEEP LAYER MOISTURE ~ PWATS AROUND 1.60 INCHES A SMALL
THREAT (< 20 PERCENT) OF LIGHT RAINFALL WILL EXIST THIS MORNING WITH
ONLY SLIGHTLY GREATER CHANCES THIS AFTERNOON...MAINLY NORTH AND WEST
OF THE TREASURE COAST/OKEECHOBEE COUNTY. WILL LEAVE OUT MENTION OF
THUNDER AT THIS TIME DUE TO WEAK MID LEVEL LAPSE RATES.
MEANWHILE...THE WEAK SURFACE FRONTAL BOUNDARY WILL GRADUALLY BEGIN
TO LIFT BACK NORTHWARD DURING THE DAY AS A WARM FRONT AS EAST
CENTRAL FLORIDA OFFICIALLY BECOMES THE WARM SECTOR AHEAD OF THE
APPROACHING COLD FRONT FOR SUNDAY. AFTERNOON HIGHS WARM AGAIN AND IN
THE UPPER 70S WITH SOME LOWER 80S POSSIBLE ACROSS THE INTERIOR.

WINDS WILL BE FAIRLY LIGHT TONIGHT...SOUTH TO SOUTHWEST WITH SHORT
TERM MODELS HINTING AT POSSIBLE PATCHY FOG OR LOW (STRATUS) CLOUD
DEVELOPMENT ONCE AGAIN. OVERNIGHT LOWS REMAIN MILD AND MAINLY IN THE
60S. WILL KEEP SMALL POP IN FOR THIS EVENING ONLY...FOR RAIN SHOWERS.

SUNDAY...SHORTWAVE ENERGY WILL SWEEP THE SURFACE LOW PRESSURE CENTER
FROM NEAR THE CENTRAL GULF COAST EARLY SUNDAY MORNING TO CROSS THE
CAROLINA COAST BY LATE SUNDAY AFTERNOON. SHOWERS AND STORMS EXPECTED
DAYTIME PRECEDING THE FRONTAL PASSAGE OCCURRING LATE AFTERNOON AND
EVENING. HAVE INDICATED SCATTERED POPS ALL AREAS. WILL NEED TO
MONITOR FOR THE POTENTIAL OF A FEW STRONGER STORMS...ESPECIALLY
ACROSS THE NORTHERN SECTIONS WITH CLOSER PROXIMITY OF JET ENERGY AND
APPROACHING SURFACE BOUNDARY...PROVIDED SUFFICIENT DESTABLIZIATION
CAN OCCUR WITH MAX TEMPS EXPECTED TO REACH THE LOWER 80S BEFORE RAIN
ARRIVES...AND MID 80S ACROSS THE SOUTH. WINDY CONDITIONS ALSO
DEVELOPING DAYTIME SUNDAY. BEHIND THE FRONT....BREEZY NORTHWEST
WINDS INTO SUNDAY NIGHT WILL USHER IN A COOLER AIRMASS WITH LOWS
DROPPING INTO THE UPPER 40S AND LOW 50S ACROSS MOST OF THE AREA.

MON-FRI...COOL POST-FRONTAL AIR MASS MONDAY BUT TEMPERATURES QUICKLY
REBOUND AS FLOW VEERS TO AN ONSHORE COMPONENT IN THE AFTERNOON WITH
CONTINUED VEERING INTO MID WEEK AND TEMPS BACK ABOVE SEASONAL
NORMALS DURING THE MID TO LATE WEEK. HAVE INDICATED ADDITIONAL LOW
RAIN CHANCES MID TO LATE WEEK...MAINLY NORTHERN SECTIONS WITH SOME
MOISTURE POOLING AND IMPULSES ALOFT IN ACTIVE SOUTHERN STREAM.
ANOTHER FRONTAL SYSTEM APPROACHING THE PENINSUAL TOWARD NEXT WEEKEND.

&&

.AVIATION...SHORT RANGE MODELS ADAMANT WITH MIXTURE OF MVFR/IFR
CIGS/VSBYS THRU MID MORNING. WINDS FAIRLY LIGHT THROUGH THE PERIOD
AS THE PRESSURE GRADIENT REMAINS VERY WEAK. VFR CONDS RETURNING LATE
MORNING/EARLY AFTERNOON AS WEAK QUASI-STATIONARY SURFACE BOUNDARY
DRAPED OVER THE AREA MOVES BACK NORTHWARD AS A WARM FRONT. MAINLY
SCHC FOR LIGHT RAIN SHOWERS THRU THIS EVENING. A WEAK EAST COAST SEA
BREEZE BOUNDARY IS FORECAST TO DEVELOP AGAIN AND MOVE SLOWLY INLAND.
POSSIBLE COLLISION WITH ITS WEST COAST PARTNER IN CRIME LATE IN
DAY/EARLY EVENING WITH SHOWERY PRECIPITATION POSSIBLY RESULTING. LOW
STRATUS AND/OR PATCHY FOG DEVELOPMENT HINTED AT AGAIN OVERNIGHT FROM
SHORT-TERM MODELS.

&&

.MARINE...TODAY-TONIGHT...WEAK PRESSURE GRADIENT REMAINS ACROSS THE
AREA WITH SOME DEGREE OF VARIABILITY IN THE WIND DIRECTIONAL
COMPONENT CONTINUING FOR THE TODAY PERIOD. HOWEVER...EARLY MORNING
LIGHT NW FLOW FORECAST TO GRADUALLY BECOME S/SE LATE IN DAY AS WEAK
FRONTAL BOUNDARY DRAPED OVER THE AREA MOVES BACK NORTHWARD AS A WARM
FRONT. ANOTHER WEAK EAST COAST SEA BREEZE BOUNDARY IS FORECAST TO
FORM THIS AFTERNOON BACKING WINDS NEAR THE COAST. WINDS WILL
CONTINUE TO VEER TO SSW BY DAYBREAK SUN MORNING AHEAD OF APPROACHING
COLD FRONTAL BOUNDARY. SPEEDS TO REMAIN 10 KTS OR LESS INTO EARLY
EVENING...BUT WILL THEN BEGIN TO RESPOND TO A TIGHTENING OF THE
PGRAD. SPEEDS ARE FORECAST TO INCREASE 15-20/20 KTS AWAY FROM THE
COAST AFT MIDNIGHT AND BY SUNRISE SUN MORNING. SEAS 3 FT OR LESS
TODAY GRADUALLY BUILDING 3-5 FT OFFSHORE LATE OVERNIGHT. DOMINANT
WAVE PERIODS TODAY 8-9 SECONDS. THE LONGER PERIOD SWELL COMBINED
WITH THE NEW MOON PHASE WILL PROMPT A MODERATE THREAT FOR RIP
CURRENTS AT EAST CENTRAL FLORIDA BEACHES TODAY.

SUN-TUE...WINDS WILL INCREASE OUT OF THE SOUTH-SOUTHWEST SUNDAY
MORNING AS LOW PRESSURE MARCHES FROM THE CENTRAL GULF COAST TO THE
CAROLINAS WITH TRAILING COLD FRONT PUSHING DOWN THE PENINSULA LATE
IN THE DAY AND EVENING. HAVE RAISED A SCA STARTING SUNDAY MORNING
AND MAY ALSO NEED TO HOIST A GALE WATCH/WARNING FOR NORTHERN
OFFSHORE SECTIONS FOR LATE SUNDAY/SUNDAY NIGHT...BUT WILL DEFER TO
DAY SHIFT AFTER EXAMINATION OF 12Z RUNS. SEAS WILL ALSO INCREASE
FROM THE STRONGER WINDS...BUILDING TO 6-7FT OFFSHORE ON SUNDAY AND
8-9FT ON MONDAY WITH THE NW FLOW BEHIND THE FRONT. HIGHER SEAS ARE
EXPECTED TO LINGER INTO THE MIDDLE OF NEXT WEEK AS PRESSURE GRADIENT
REMAINS FAIRLY ROBUST ACROSS THE LOCAL WATERS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TONIGHT.

.DENSE FOG/SMOKE IMPACT...
AREAS OF FOG WILL DEVELOP ACROSS EAST CENTRAL FLORIDA OVERNIGHT AS
DEEP MOISTURE AND LIGHT WINDS DEVELOP AROUND A FRONTAL BOUNDARY
STALLED JUST NORTH OF THE I-4 CORRIDOR. THE FOG COULD BECOME
LOCALLY DENSE IN THE EARLY MORNING HOURS WITH VISIBILITY FALLING
TO A QUARTER MILE OR LESS. THE BEST CHANCE FOR FOG FORMATION WILL
BE ALONG AND NORTH OF THE I-4 CORRIDOR...AS WELL AS EAST ORANGE
AND NORTH BREVARD COUNTY.

DRIVERS ARE URGED TO SLOW DOWN WHEN ENCOUNTERING FOG...ESPECIALLY
IN AREAS WITH ACTIVE WILDFIRES...AS VISIBILITY CAN CHANGE RAPIDLY
AT HIGHWAY SPEEDS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
WINDS AND SEAS WILL INCREASE OVER THE WEEKEND INTO EARLY NEXT
WEEK...AS A LOW PRESSURE CENTER MOVES FROM THE NORTHERN GULF OF
MEXICO COAST TOWARDS THE CAROLINAS. THERE WILL BE A CHANCE OF
THUNDERSTORMS LATE SATURDAY INTO SUNDAY AS A COLD FRONT DROPS
THROUGH CENTRAL FLORIDA.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
