NATIONAL WEATHER SERVICE MELBOURNE FL
339 AM EST FRI DEC 21 2012

.DISCUSSION...

...BRISK NORTHWEST WINDS WILL USHER IN A MUCH DRIER AND COLDER
AIRMASS TODAY INTO TONIGHT...

CURRENTLY-TODAY...COLD FRONT CURRENTLY MOVING THROUGH THE AREA WILL
PUSH SOUTH OF LAKE OKEECHOBEE BY EARLY THIS MORNING WITH RAIN
CHANCES ENDING AND SKIES CLEARING. NORTHWEST WINDS WILL INCREASE
BEHIND THE BOUNDARY UP TO AROUND 20 MPH BY LATE MORNING WITH GUSTS
BETWEEN 30 TO 35 MPH POSSIBLE INTO THE AFTERNOON. WILL ISSUE A LAKE
WIND ADVISORY FOR THESE WINDY CONDITIONS TODAY. THESE WINDS WILL
USHER ONE OF THE COLDEST AIRMASSES SO FAR THIS SEASON WITH HIGHS
TODAY EXPECTED TO BE AROUND 10 DEGREES BELOW NORMAL. MAX TEMPS WILL
RANGE FROM THE UPPER 50S OVER NORTHERN LAKE/VOLUSIA COUNTIES TO MID
60S ALONG THE SOUTHERN TREASURE COAST.

TONIGHT...MAIN FORECAST CHALLENGE TONIGHT IS WITH OVERNIGHT LOWS.
NORTHWEST WINDS WILL DECREASE TOWARD SUNSET BUT STILL REMAIN
ELEVATED UP TO AROUND 10 MPH INLAND TO 10 TO 15 MPH ALONG THE COAST
AS STRONG CAA CONTINUES. MOS GUIDANCE CONTINUES TO APPEAR TOO LOW
WITH TEMPS WHICH IS NOT UNUSUAL FOR THESE ADVECTIVE EVENTS. WHILE
ERRING ON THE SIDE OF CAUTION...WENT ON AVERAGE ABOUT 3-4 DEGREES
ABOVE MAV GUIDANCE FOR LOWS TONIGHT. THIS PUTS VALUES AROUND 10 TO
15 DEGREES BELOW NORMAL IN THE MID/UPPER 30S OVER MUCH OF THE
AREA...EXCEPT LOW 40S ALONG THE BARRIER ISLANDS AND IMMEDIATE COAST
OF ST. LUCIE/MARTIN COUNTIES. STILL...WINDS WILL MAKE IT FEEL MUCH
COLDER IN THE UPPER 20S TO LOW 30S AFTER MIDNIGHT TONIGHT THROUGH
EARLY SATURDAY MORNING. WILL GO AHEAD AND ISSUE A WIND CHILL
ADVISORY ACROSS THE AREA WITH THIS FORECAST PACKAGE SINCE IT LOOKS
QUITE CERTAIN THESE CONDS WILL OCCUR.

SAT-SAT NIGHT...HIGH PRESSURE OVER THE GULF COAST STATES WILL DRIFT
EASTWARD TO ACROSS THE FLORIDA PENINSULA BY THE END OF THIS PERIOD.
THIS WILL WEAKEN THE PRESSURE GRADIENT WITH NORTHWEST WINDS 10-15
MPH DURING THE DAY FALLING TO LIGHT/VARIABLE OR CALM DURING THE
EVENING AND OVERNIGHT PERIOD. DEWPOINT VALUES WILL FALL INTO THE 20S
TO LOWER 30S AREAWIDE. CONDITIONS WILL REMAIN DRY. SOME PATCHY FROST
MAY BE POSSIBLE OVER THE INTERIOR SAT NIGHT...ESPECIALLY WEST OF
I-95.

UNSEASONABLY COOLER TEMPERATURES WILL CONTINUE WITH HIGHS IN THE
UPPER 50S TO AROUND 60 DEGREES NEAR AND NORTH OF THE I-4 CORRIDOR.
SOUTH FROM HERE TEMPERATURES WILL REACH THE LOWER 60S WITH A FEW
MIDDLE 60S POSSIBLE ALONG THE MARTIN COUNTY COAST. WHILE WIND CHILL
VALUES WILL NOT BE AN ISSUE THIS NIGHT DUE TO THE LIGHT WINDS VERY
COLD TEMPERATURES WILL OCCUR WITH OPTIMAL RADIATIONAL COOLING.
EXPECT OVERNIGHT LOWS MAINLY IN THE MIDDLE 30S OVER THE INTERIOR
WITH LOWER 30S LIKELY OVER MORE WIND SHELTERED/COLD PRONE AREAS.
UPPER 30S TO NEAR 40 DEGREES NEAR THE COAST AND OVER THE ORLANDO
METRO. LOWER 40S POSSIBLE NEAR THE MARTIN COUNTY COAST.

SUN-MON...THE WIND FLOW ALOFT REMAINS NEAR ZONAL WITH THE JET STREAM
SITUATED ACROSS THE SOUTHERN CONUS DURING THIS TIME. SURFACE HIGH
PRESSURE GRADUALLY MOVES EAST INTO THE WESTERN ATLANTIC ON SUN WITH
ASSOCIATED EAST-WEST ORIENTED RIDGE AXIS FIXATED ACROSS EAST CENTRAL
FLORIDA. CONDITIONS CONTINUE TO REMAIN DRY AND COOLER SUN BUT
TEMPERATURES ARE FORECAST SLIGHTLY ABOVE CLIMO BY MON AS SOUTHERLY
LOW-LEVEL FLOW BRINGS WARMER AND MORE MOIST AIR BACK TO THE REGION.
HIGHS IN THE 60S AREAWIDE ON SUN GIVE WAY TO 70S ON MON. OVERNIGHT
LOWS SUN NIGHT MAINLY IN THE 40S...BUT INCREASE INTO THE 50S
AREAWIDE MON OVERNIGHT.

CHRISTMAS DAY...THE WARM-UP CONTINUES WITH MIDDLE TO UPPER 70S
ACROSS EAST CENTRAL FLORIDA. CONDITIONS CONTINUE MAINLY DRY WITH THE
RIDGE AXIS CONCENTRATED OVER THE CENTRAL PENINSULA. CONTINUED
SOUTHERLY FLOW WILL ALLOW DEWPOINT VALUES TO CREEP BACK INTO THE
50S. A DEVELOPING LOW PRESSURE SYSTEM NEAR THE ARKLATECH REGION WILL
LIFT NORTHEASTWARD OVERNIGHT TOWARD THE TENNESSEE VALLEY WITH A COLD
FRONT TRAILING SOUTHWARD AND MOVING INTO THE WESTERN FLORIDA
PANHANDLE BY DAYBREAK WED MORNING. OVERNIGHT LOWS IN THE 50S ACROSS
THE INTERIOR WITH LOWER TO MIDDLE 60S ALONG THE SPACE AND TREASURE
COASTS.

FAIRLY WARM DAY WITH TEMPERATURES AHEAD OF THE FRONT SURGING INTO
THE MIDDLE TO UPPER 70S. OVERNIGHT LOWS MAINLY IN THE 50S WED NIGHT.

TIME WITH STRONG COLD AIR ADVECTION SPREADING SOUTHWARD. EARLY IN
THE PERIOD NORTHWEST WINDS OFFSHORE CONTINUE IN UPWARDS OF 25 KTS
WITH OCCASIONAL GUSTS TO NEAR GALE FORCE. NW WINDS ARE FORECAST TO
DECREASE GRADUALLY THROUGH THE DAY...THOUGH VERY COOL WINDS WILL
STILL OPPOSE THE WARMER GULF STREAM WATERS ALLOWING FOR STRONGER
WINDS AND HIGHER SEAS TO CONTINUE HERE A WHILE LONGER. WIND SPEEDS
ARE FORECAST TO FALL TO AROUND 10 KTS BY DAYBREAK SUN MORNING. SEAS
7-10 FT OFFSHORE/GULF STREAM AND 5-9 FT NEAR SHORE INITIALLY. SAT

SEGMENT.

&&

.FIRE WEATHER...BRISK NORTHWEST WINDS WILL USHER IN A MUCH DRIER AND
COLDER AIRMASS INTO THE REGION TODAY. THESE WINDS WILL COMBINE WITH
A LONG DURATION OF VERY LOW RH VALUES OVER CENTRAL FLORIDA TO
PRODUCE DANGEROUS FIRE WEATHER CONDS INTO THIS AFTERNOON. A RED FLAG
WARNING CONTINUES OVER ALL OF EAST CENTRAL FLORIDA TODAY.

SAT-SUN...WITH HIGH PRESSURE BUILDING INTO THE AREA...THE PRESSURE
GRADIENT WILL BE WEAKER WITH 20 FT WINDS STAYING BELOW 15 MPH DURING

HUMIDITY VALUES FALLING INTO THE 20S AREAWIDE AND SOME RHS IN THE
TEENS POSSIBLE OVER THE INTERIOR. CRITICAL RH VALUES EXPECTED FOR
SEVERAL HOURS ON SAT. PRESENTLY FEEL THAT ERC NUMBERS WILL REMAIN
BELOW 35 SO A FIRE DANGER STATEMENT IS MORE LIKELY ON SAT. A FIRE
DANGER STATEMENT MAY BE NECESSARY AGAIN ON SUN OVER THE INTERIOR AND
POSSIBLE ALONG THE COAST FROM BREVARD COUNTY NORTHWARD DUE TO LONG
DURATION LOW RHS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS EVENING AND TONIGHT.

.THUNDERSTORM IMPACT...
A FRONTAL BOUNDARY WILL APPROACH CENTRAL FLORIDA THIS EVENING AND
MOVE THROUGH THE FLORIDA PENINSULA OVERNIGHT. TORNADO WATCHES HAVE
BEEN IN EFFECT FOR PARTS OF THE PANHANDLE TODAY FOR CONVECTION
JUST AHEAD AND ALONG THE FRONT. THE THREAT OF SEVERE STORMS WILL
TRANSITION EAST AND NORTHEAST WITH TIME TO IMPACT PARTS OF THE
NORTH FLORIDA PENINSULA AND UP THROUGH GEORGIA AND THE CAROLINAS.
A SLIGHT RISK IS OUTLOOKED BY THE STORM PREDICTION CENTER FOR THIS
AREA. AS THE BAND OF CONVECTION NEARS CENTRAL FLORIDA...THE
BOUNDARY WILL STRETCH AND THIN LEAVING MAINLY THE POSSIBILITY OF
ISOLATED TO SCATTERED STRONG SHOWERS AND STORMS FROM TITUSVILLE TO
KISSIMMEE NORTHWARD. ALTHOUGH LOCAL INSTABILITY REMAINS
LIMITED...APPRECIABLE WIND SHEAR WILL PROMPT A CONCERN FOR STRONG
WIND GUSTS TO 45-50 MPH WITH A FEW CELLS. A SEVERE STORM IS
UNLIKELY...BUT NOT OUT OF THE QUESTION.

EXPECT SHOWERS AND STORMS TO APPROACH LAKE COUNTY JUST AFTER SUNSET
AS THE BOUNDARY MOVES SOUTHEAST THROUGH THE FORECAST AREA DURING THE
EVENING AND OVERNIGHT HOURS. SHOWERS AND STORMS SHOULD APPROACH
DAYTONA BEACH LATER THIS EVENING...ORLANDO AND CAPE CANAVERAL JUST
BEFORE MIDNIGHT...REDUCING TO SHOWER ACTIVITY AS IT PASSES THROUGH
VERO BEACH...FORT PIERCE...AND STUART OVERNIGHT AND BEFORE
SUNRISE.

.MARINE THUNDERSTORM GUST IMPACT...
A BAND OF SHOWERS AND ISOLATED TO SCATTERED STORMS WILL ACCOMPANY A
FRONT AS IT MOVES SOUTHWARD THROUGH EAST CENTRAL FLORIDA LATE THIS
EVENING AND OVERNIGHT. SOME WIND GUSTS TO 45 KNOTS MAY OCCUR AS THEY
MOVE OFFSHORE TO THE EAST-NORTHEAST WITHIN THE BAND AT 30 TO 35
KNOTS.

.WIND AND SEA IMPACT...
A GALE WARNING IS IN EFFECT FOR THE OFFSHORE LEG OF THE VOLUSIA
COUNTY WATERS AND FOR THE WATERS NORTHWARD. WINDS WILL CONTINUE TO
INCREASE OUT OF THE SOUTH AND SOUTHWEST TO 20 KNOTS AS A FRONTAL
BOUNDARY APPROACHES THE ADJACENT COASTAL WATERS. WINDS WILL BECOME
20 TO 25 KNOTS LATE THIS EVENING AND THEN NORTHWEST BY DAYBREAK
FRIDAY AS THE FRONTAL BOUNDARY CROSSES THE REGION. WINDS WILL REACH
TO 30 KNOTS OFFSHORE WITH OCCASIONAL GUSTS TO GALE FORCE IN MANY
PLACES. MORE SO...THERE WILL BE FREQUENT GUSTS TO GALE FORCE BEYOND
20 MILES FROM THE COAST BETWEEN FLAGLER BEACH TO THE BREVARD COUNTY
LINE. AS A RESULT...A GALE WARNING HAS BEEN ISSUED THERE. SMALL
CRAFT ADVISORIES ARE IN EFFECT ELSEWHERE. SEAS WILL BUILD STARTING
LATE TONIGHT TO 6 TO 10 FEET OFFSHORE...ESPECIALLY OVER THE GULF
STREAM.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY. SOME OF THE
COLDEST AIR OF THE SEASON WILL ARRIVE BEHIND THE FRONT WITH MORNING
LOW TEMPERATURES INTO THE WEEKEND RANGING FROM THE MID 30S TO 40
DEGREES ACROSS MUCH OF EAST CENTRAL FLORIDA. BREEZY WINDS OVERNIGHT
FRIDAY INTO SATURDAY MORNING WILL BRING BELOW FREEZING WIND CHILL
VALUES. TEMPERATURES WILL BE IN STARK CONTRAST TO THOSE EXPERIENCED
OVER RECENT DAYS. FOLKS WILL NEED TO DRESS WITH COATS AND HATS IF
OUTSIDE AND ALSO TAKE ANY NECESSARY PRECAUTIONS FOR PETS TO PROTECT
THEM FROM THE COLD.

HAZARDOUS MARINE CONDITIONS WILL CONTINUE THROUGH THE WEEKEND BEHIND
A FRONTAL PASSAGE EARLY FRIDAY MORNING. THE STRONG NORTH WINDS WILL
BUILD SEAS ALONG WITH GUSTS TO GALE FORCE POSSIBLE OFFSHORE FRIDAY
AND FRIDAY NIGHT. WINDS AND SEAS WILL BE HIGHER IN THE GULF STREAM.

FOR WILDFIRE WEATHER CONCERNS...MINIMUM RELATIVE HUMIDITIES WILL BE
BELOW 35 PERCENT WITH BRISK NORTHWEST WINDS. A RED FLAG WARNING IS
IN EFFECT FOR ALL COUNTIES FOR FRIDAY DUE TO THE VERY DRY CONDITIONS.
CONCERNS WILL EVIDENT FOR BOTH SATURDAY AND SUNDAY AFTERNOONS AS
WELL.
