AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
410 AM EST MON JAN 10 2011

...LOW CHANCE OF FREEZING RAIN THIS MORNING FROM DOUGLAS TO ODUM...
...LOW CHANCE OF STRONG TSTORMS MIDDAY ACROSS COASTAL AND FL ZONES...
...COLD TEMPS WED THROUGH FRI WITH FREEZES LIKELY...

.SHORT TERM...THE STRENGTH OF DYNAMICS AROUND THE APPROACHING GOMEX
SFC LOW ERODED THE SFC WEDGE THAT WAS OVER OUR NORTHERN ZONES. WARM
AIR ADVECTION WAS OCCURRING ACROSS OUR ZONES DUE TO ENE WINDS VS NNE
IF THE WEDGE HAD HELD ACROSS THE AREA. MODEL SOUNDINGS AND NOMOGRAMS
STILL SUPPORT A VERY SLIGHT CHANCE OF FREEZING RAIN ACROSS OUR NW GA
ZONES FROM DOUGLAS TO ODUM THROUGH 15Z WHERE EVAPORATIONAL COOLING
IN THE LOW LEVELS MAY SATURATE AND COOL THE LOW LEVELS ENOUGH FOR FREEZING
RAIN. GIVEN WARM GROUNDS ACCUMULATION WILL NOT OCCUR...AND MAIN
AREAS OF CONCERN WILL CONTINUE TO BE OVERPASSES AND BRIDGES. THE
CURRENT WINTER WEATHER ADVISORY REMAINS IN EFFECT THROUGH 10 AM THIS
MORNING. BY LATE MORNING...TOO MUCH WARM AIR WILL BE IN PLACE AS THE
LOW APPROACHES WITH WIDESPREAD RAIN ACROSS OUR GA ZONES AND
SCATTERED SHRA ACROSS OUR FL ZONES NEAR THE APPROACHING WARM FRONT.

THERE ARE INCREASED PROBS OF TSTORMS ACROSS OUR COASTAL AND N FL
ZONES THIS AFTERNOON NEAR AND SOUTH OF THE APPROACHING WARM FRONT.
SATELLITE SHOWS TS FIRING IN ADVANCE OF THE APPROACHING COLD FRONT
ACROSS THE EASTERN GULF...WITH ELEVATED TS N OF THE WARM FRONT OVER
THE FL PANHANDLE. MODEL SOUNDINGS SHOW CAPPED LOW LEVELS AND WEAK
INSTABILITY ACROSS OUR ZONES TODAY...BUT IF ENOUGH VEERING OF WINDS
BELOW 850 CAN OCCUR AND ADVECT SLIGHTLY WARMER AND MORE MOIST GOMEX
AIR ACROSS THE CWA...SFC BASED CAPES AND LIFTED INDICES WOULD RISE
ENOUGH NEAR AND ALONG THE WARM FRONT AND ALONG THE COLD FRONT THIS
BY MIDDAY TO SUPPORT ISOLD TS. STRONG STORMS WILL BE POSSIBLE IF
STORMS DUE MANIFEST WITH GUSTY WINDS AND ROTATING CELLS GIVEN A
STRONG LLVL JET AND STORM RELATIVE HELICITY VALUES.

TEMPS WILL RANGE FROM THE 40S ACROSS OUR NW GA ZONES TO NEAR 70
SOUTH TODAY. PRECIP WILL DECREASE THIS EVENING FROM W TO E AS DRIER
AIR BEGINS TO INFILTRATE IN THE MID LEVELS. LINGERING LOW LEVEL
WRAP-AROUND MOISTURE AS THE SFC LOW CROSSES AND DEPARTS NE ALONG THE
ATLANTIC SEABOARD MAY YIELD PATCHY DRIZZLE ACROSS THE AREA. AREAS OF
FOG ARE LIKELY ACROSS MANY AREAS AFTER MIDNIGHT DUE TO LINGERING
GROUND MOISTURE AND A LINGERING WAKE TROUGH POOLING MOISTURE AND
BRINGING LIGHT WINDS.

MINS TONIGHT WILL RANGE FROM MID 30S TO NEAR 50 ACROSS THE SOUTH.
TUE TEMPS WILL REMAIN COOL ACROSS GA WITH HIGHS NEAR 50 TO UPPER 60S
TO THE SOUTH. TUE NIGHT A REINFORCING TROUGH WILL PUSH SOUTH OF THE
CWA WITH MUCH COLDER AIR ACROSS THE CWA WITH A FREEZE EXPECTED
ACROSS INLAND AREAS AND DUE TO ELEVATED WINDS A WIND CHILL ADVISORY
LIKELY FOR NE FL.

.LONG TERM...WED THROUGH FRI A COLD AIRMASS WILL BE IN PLACE AS A
VERY STRONG SFC HIGH BUILDS FROM THE CENTRAL CONUS SLOWLY EASTWARD.
HIGHS WILL RANGE IN THE 50S WITH MINS BELOW FREEZING WITH A POSSIBLY
HARD FREEZE THU MORNING.

THE SFC RIDGE GRADUALLY WEAKENS WHILE SHIFTING FARTHER SSE AND SAT
ONSHORE FLOW DEVELOPS LOCALLY WITH HIGHS WARMING INTO THE 60S OVER
THE WEEKEND. INTRODUCED A LOW CHANCE OF SHRA MON AS THE NEXT FRONT
APPROACHES FROM THE NW.

&&

.AVIATION...
STILL HANGING ON TO VFR CIGS PRIOR TO ANY PCPN AT TAF SITES EARLY
THIS MORNING. OTHERWISE LOW LEVEL WIND SHEAR EXISTS AT ALL TAF SITES
AND STILL EXPECTING A TREND DOWNWARD IN CIGS TO MVFR LEVELS THIS
MORNING AS RAIN DEVELOPS ACRS THE REGION. WILL KEEP VCTS AT ALL TAF
SITES AS A CHANCE OF THUNDER WILL REMAIN POSSIBLE FROM THE MID
MORNING HOURS INTO THE AFTERNOON.

&&

.MARINE...
STRONG ONSHORE FLOW WILL BECOME SOUTHERLY THIS AFTERNOON AS THE
DEVELOPING LOW PRESSURE TRACKS TOWARD THE LOCAL WATERS. STRONG SCA
CONDS WILL CONTINUE THROUGH THE DAY WITH GALE FORCE GUSTS POSSIBLE
BUT CONFIDENCE NOT HIGH ENOUGH TO HOIST A GALE WARNING. WINDS WILL
DIMINISH THIS EVENING AS LOW PRESSURE DEPARTS THE REGION AND SCA
FLAGS WILL EXPIRE. NEXT COLD AIR OUTBREAK WILL PUSH NORTHWEST WINDS
BACK TO SCA LEVELS TUE NIGHT AND WILL CONTINUE WED/THU.
