AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
513 AM EST THU DEC 20 2012

...BECOMING BREEZY WITH NEAR RECORD HIGHS IN NORTHEAST FLORIDA...

...SQUALL LINE WITH POSSIBLE DAMAGING WIND GUSTS MOVES THROUGH LATE
THIS AFTERNOON THROUGH THE EVENING HOURS...

...GALE WARNING FOR THE OFFSHORE WATERS FROM TONIGHT THROUGH EARLY
SATURDAY...

...WIDESPREAD FREEZES FOR ALL BUT THE IMMEDIATE COAST ON SATURDAY
AND SUNDAY MORNINGS...

.CURRENTLY...
EARLY MORNING SURFACE ANALYSIS DEPICTS HIGH PRESSURE EXTENDING
FROM THE MID-ATLANTIC STATES SOUTHEASTWARD INTO THE WESTERN
ATLANTIC. A STRENGTHENING SURFACE LOW (993 MILLIBARS) WAS LOCATED
OVER MISSOURI WITH A TRAILING COLD FRONT FROM THE MIDDLE AND LOWER
MISSISSIPPI RIVER VALLEY TO THE FAR WESTERN GULF OF MEXICO.
ALOFT...A POTENT SHORTWAVE WAS MOVING NORTHEASTWARD THROUGH
EASTERN PORTIONS OF KANSAS AND NEBRASKA...WITH STACKED RIDGING
LOCATED DOWNSTREAM OF THIS FEATURE OVER THE BAHAMAS AND EASTERN
CUBA. THIS FEATURE IS MAINTAINING A VERY DRY AIR MASS OVER OUR
REGION EVEN THOUGH SOUTHERLY FLOW JUST OFF THE SURFACE IS
INCREASING. STRONG WESTERLY FLOW IN THE UPPER ATMOSPHERE IS
ADVECTING A DECK OF HIGH CLOUDINESS INTO THE FLORIDA PANHANDLE AND
SOUTHEASTERN GEORGIA.

.SHORT TERM (TODAY THROUGH SATURDAY NIGHT)...
THE STRONG COLD FRONT CURRENTLY CROSSING THE MISSISSIPPI RIVER
WILL BLAST THROUGH THE SOUTHEASTERN STATES...AS THE AFOREMENTIONED
POTENT SHORTWAVE MOVES NORTHEASTWARD TOWARDS THE GREAT LAKES
STATES. EXPECT MAINLY HIGH CLOUDINESS TO GRADUALLY INCREASE THIS
MORNING...WHILE WINDS GRADUALLY INCREASE FROM A SOUTHERLY
DIRECTION. WILL LEAVE POPS OUT OF THE GRIDS THROUGH NOON FOR AREAS
NEAR THE ALTAMAHA RIVER IN SE GA. WARM AIR SURGING AHEAD OF THE
FRONT AND FILTERED SUNSHINE THROUGH EARLY AFTERNOON WILL ALLOW
TEMPERATURES TO RAPIDLY RISE AND APPROACH RECORD VALUES OVER NE
FL...OR NEAR 80 DEGREES. THICKER CLOUD COVER LATER THIS AFTERNOON
SHOULD KEEP HIGHS OVER SE GA IN THE MID/UPPER 70S. A SQUALL LINE
OF GUSTY SHOWERS AND EMBEDDED THUNDERSTORMS WILL PRECEDE THE COLD
FRONT...MOVING INTO SE GA TOWARDS SUNSET AND ROCKETING ACROSS
NE FL DURING THE EVENING HOURS. INSTABILITY WILL REMAIN LIMITED
IN A NARROW CORRIDOR AHEAD OF THE FRONT...WITH MIXED LAYER CAPES
OF AROUND 250-500 J/KG. HOWEVER...WIND ENERGY WITH THIS FRONTAL
PASSAGE WILL BE IMPRESSIVE...WITH SOUTHWEST WINDS OF 35 TO 50
KNOTS FROM 1000 TO 5000 FEET BY THE LATE AFTERNOON HOURS. HEAVIER
SHOWERS AND THUNDERSTORMS WILL HAVE THE POTENTIAL TO BRING THESE
WINDS DOWN TO THE SURFACE. THUS...THE STORM PREDICTION CENTER HAS
KEPT ALL OF SE GA AND THE INTERSTATE 10 CORRIDOR OF NE FL IN A
SLIGHT RISK FOR SEVERE THUNDERSTORMS...WITH DAMAGING WIND GUSTS
BEING THE PRIMARY THREAT. LOW-LEVEL WIND FIELDS WILL BE
UNIDIRECTIONAL BY THE TIME THE SQUALL LINE ARRIVES...AND THUS
THERE IS A VERY LOW RISK OF TORNADOES IS IN PLACE WITH THIS EVENT.
A LAKE WIND ADVISORY WILL LIKELY BE ISSUED LATER TODAY.

HIGH RESOLUTION SHORT TERM MODELS REMAIN IN GOOD AGREEMENT ON
TIMING OF THE FRONTAL PASSAGE...WITH THE BOUNDARY CROSSING THE
ALTAMAHA RIVER TOWARDS 00Z AND EXITING THE ATLANTIC COAST AROUND
06Z. SKIES WILL RAPIDLY CLEAR IN THE WAKE OF THE FRONT. STRONG
NORTHWEST FLOW WILL BUILD INTO OUR AREA OVERNIGHT...AND A
TIGHTENING PRESSURE GRADIENT WILL BRING GALE CONDITIONS TO THE
OFFSHORE WATERS. LAKE WIND ADVISORIES WILL BE NECESSARY THROUGHOUT
THE REGION. SIGNIFICANT COLD AIR ADVECTION WILL DROP LOWS INTO
THE 30S IN INTERIOR SE GA...WHERE WIND CHILLS WILL FALL BELOW
FREEZING DURING THE PREDAWN HOURS. LOWS IN NE FL WILL FALL INTO
THE 40S.

STRONG LOW PRESSURE OVER THE GREAT LAKES STATES WILL MAINTAIN A
BRISK NORTHWESTERLY FLOW OVER THE AREA ON FRI. LAKE WIND
ADVISORIES WILL CONTINUE...AND COLD AIR ADVECTION WILL KEEP
HIGHS IN THE 50S REGION-WIDE. SURFACE RIDGING WILL THEN BUILD
EASTWARD FROM THE LOWER MISSISSIPPI RIVER VALLEY ON FRI
NIGHT...ALLOWING WINDS TO BECOME NORTHERLY AND GRADUALLY
DECREASE IN SPEED. A SIGNIFICANT ADVECTION FREEZE IS EXPECTED FOR
ALL AREAS EXCEPT THE IMMEDIATE COAST...ALTHOUGH DURATIONS OF SUB-
FREEZING TEMPERATURES SHOULD BE LIMITED BY WIND SPEEDS REMAINING
NEAR 10 MPH. EXPECT LOWS TO FALL INTO THE MID/UPPER 20
INLAND...RANGING TO THE MID 30S AT THE COAST. A FREEZE WATCH HAS
THUS BEEN ISSUED FROM 06Z-13Z SAT. A CHILLY DOME OF HIGH PRESSURE
WILL THEN MOVE OVERHEAD BY LATE SAT AND SAT NIGHT. A LONGER
DURATION FREEZE IS POSSIBLE FOR ALL BUT THE IMMEDIATE COAST...AND
LOWS WILL BE SIMILAR TO FRI NIGHT'S VALUES.

.LONG TERM (SUNDAY THROUGH WEDNESDAY)...
OUR FLOW ALOFT WILL TRANSITION FROM NORTHWESTERLY ON SUN TOWARDS A
MORE ZONAL REGIME EARLY NEXT WEEK...AS SIGNIFICANT TROUGHING
MIGRATES OUT OF THE WESTERN STATES. TEMPERATURES ON SUN WILL
REMAIN BELOW CLIMO WITH SOME INCREASE IN HIGH CLOUDINESS AS A WEAK
SHORTWAVE MOVES THROUGH THE REGION. AFTER A POTENTIALLY FROSTY
START ON CHRISTMAS EVE...TEMPERATURES WILL WARM BACK TOWARDS CLIMO
AS HIGH PRESSURE SLIDES INTO THE WESTERN ATLANTIC. A WARM FRONT
MAY DEVELOP OVER SE GA BY EARLY TUES...BUT HAVE KEPT ONLY ISOLATED
POPS IN THE FORECAST GRIDS THROUGH CHRISTMAS NIGHT...MAINLY OVER
SE GA...AS MOST OF THE FORCING REMAINS WEST OF OUR REGION.
TEMPERATURES WILL RISE TO NEAR CLIMO FOR CHRISTMAS EVE AND THEN
ABOVE CLIMO...INTO THE 70S...FOR CHRISTMAS DAY AS SOUTH TO
SOUTHWESTERLY FLOW STRENGTHENS WARM AIR ADVECTION. GFS ENSEMBLE
AND ECMWF GUIDANCE POINT TO ANOTHER SIGNIFICANT FRONTAL PASSAGE BY
THURS...AND WE HAVE POPS RAMPING UP TO THE CHANCE CATEGORY BY LATE
WED AND WED NIGHT AHEAD OF THIS FRONT. ABOVE CLIMO TEMPS WILL
PERSIST CHRISTMAS NIGHT AND WED.

&&

.AVIATION...
PREVAILING VFR CONDITIONS THROUGH LATE AFTN. INCREASINGLY STRONG
SW WINDS WITH GUSTS TO 25 KTS ARE EXPECTED BY AFTN...WITH
LOWERING CLOUD HEIGHTS AHEAD OF THE SURFACE FRONT THROUGH THIS
EVENING. INTRODUCED VCSH AT ALL TERMINALS BY 21Z.

&&

.MARINE...
RELATIVELY QUIET CONDITIONS OVER THE WATERS BELIE WHAT IS
EXPECTED LATER TODAY. SOUTH WINDS WILL INCREASE TO 20 KT LATE THIS
AFTERNOON...THEN VEER TO SW 25-30 KT OFFSHORE THIS EVENING BEFORE
SHIFTING TO NW AFTER MIDNIGHT WITH WINDS INCREASING TO 30-35 KT.
HAVE UPGRADED TO A GALE WARNING FOR OFFSHORE LEGS. WILL KEEP SCA
FOR NEARSHORE WATERS WITH OCCASIONAL GALE FORCE GUSTS. IF THE
GUSTS ARE EXPECTED TO BE MORE FREQUENT...THEN SCA MAY BE UPGRADED
NEARSHORE. CONDITIONS ARE EXPECTED TO IMPROVE LATE SATURDAY NIGHT.

RIP CURRENTS: LOW RISK IS EXPECTED THROUGH FRIDAY.

&&

.FIRE WEATHER...
STRONG GUSTY WINDS WILL ACCOMPANY THE VERY DRY AIRMASS ON FRIDAY
PROMPTING A FIRE WEATHER WATCH. WIND GUSTS ARE EXPECTED TO BE UP
TO 30 TO 35 MPH. WINDS WILL DECREASE SATURDAY BUT CONTINUE TO BE
GUSTY...AND A WATCH IS POSSIBLE. HIGH PRESSURE WILL PASS OVER THE
REGION EARLY NEXT WEEK RESULTING IN LIGHTER WINDS AND GRADUALLY
INCREASING RH VALUES.
