Area forecast discussion, Dec 17, 2:54 PM EST, 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
254 PM EST MON DEC 17 2012

...TORNADO WATCH IN EFFECT FOR ALL OF SE GA AND THE SUWANNEE
VALLEY UNTIL 9 PM THIS EVE...

.NEAR TERM...SURFACE ANALYSIS IS SHOWING COLD FRONT MOVING ACROSS
ALABAMA INTO SE LOUISIANA AND A PRE-FRONTAL TROUGH FROM SW GA TO THE
FLORIDA PANHANDLE. A SQUALL LINE CONTINUED TO DEVELOP ALONG THE
TROUGH AND WAS BEGINNING TO MOVE INTO SE GA. AS THE PRE-FRONTAL
TROUGH MOVES ACROSS THE AREA...THE SQUALL LINE ALONG IT WILL BE
MOVING THROUGH SE GA DURING THE MID TO LATE AFTERNOON AND NE FL FROM
LATE AFTERNOON INTO THE EARLY EVE. STRONG DEEP LAYER
(UNIDIRECTIONAL) AND MARGINAL INSTABILITY WILL RESULT IN A FEW OF
THE STORMS POSSIBLY BECOMING SEVERE WITH DAMAGING WINDS AND ISOLATED
TORNADOES THE MAIN CONCERNS. SPC HAS PUT ALL OF SE GA...THE ADJACENT
SE GA COASTAL WATERS...AND THE SUWANNEE VALLEY REGION OF NE FL UNDER
A TORNADO WATCH UNTIL 9 PM THIS EVE.

.SHORT TERM (TONIGHT-TUESDAY NIGHT)...THE POTENTIAL FOR SEVERE STORMS
WILL QUICKLY WANE THIS EVE DUE TO THE LOSS OF HEATING ALTHOUGH IT WILL
REMAIN UNSTABLE ENOUGH ACROSS THE OFFSHORE WATERS FOR A FEW STORMS.
WILL GRADUALLY LOWER POPS FROM NW TO SE AS POST FRONTAL SHOWERS MOVE
THROUGH. WILL HAVE NEAR NIL POPS MOST AREAS ...EXCEPT THE FAR SE
PORTION...BY LATE TONIGHT. COLD FRONT PUSHES THROUGH LATE TONIGHT.
HIGH PRESSURE WILL BUILD IN FROM THE GULF COAST BRINGING IN CLEAR
AND MUCH DRIER CONDITIONS. TEMPERATURES WILL COOL IN THE WAKE OF THE
FRONT...WITH UPPER 60S TO LOWER 70S FOR HIGHS TUESDAY...AND LOWS IN
THE UPPER 30S TO LOWER 40S INLAND TUESDAY NIGHT.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
A PROGRESSIVE WEATHER PATTERN WILL CONTINUE...AND HEIGHTS ALOFT RISE
ON WED DOWNSTREAM OF THE NEXT AMPLIFYING TROUGH EXITING THE ROCKIES.
SURFACE RIDGING CENTERED OVER OUR REGION ON WED MORNING SLIDES
INTO THE WESTERN ATLANTIC...ALLOWING FOR SLIGHTLY ABOVE CLIMO
HIGHS AFTER A SEASONABLY COOL START...WITH LOW/MID 70S REGION-
WIDE. SOUTH TO SW FLOW ALOFT STRENGTHENS WED NIGHT AND THURS WELL
IN ADVANCE OF AN APPROACHING COLD FRONT...AND LOWS WED NIGHT SHOULD
RISE 5-10 DEGREES FROM TUES NIGHT'S VALUES. HIGHS ON THURS WILL
ONCE AGAIN APPROACH RECORDS...NEAR 80 FOR INLAND SECTIONS OF NE
FL. GUIDANCE IS TRENDING TOWARDS A FASTER COLD FRONTAL PASSAGE...AND
CHANCE POPS WERE PLACED INTO THE FORECAST GRIDS FOR INTERIOR SE GA
ON THURS MORNING. CLOUDS AND INCREASING RAIN CHANCES WILL KEEP
HIGHS IN THE MID 70S FOR SE GA. MODEL SOUNDINGS SUGGEST IMPRESSIVE
SPEED SHEAR AND JET DYNAMICS CROSSING OUR REGION LATE THURS IN
ASSOCIATION WITH THIS PROGRESSIVE TROUGH. HAVE MAINTAINED CHANCE POPS
FOR THIS EVENT THROUGHOUT THE REGION...AND ADDED ISOLATED THUNDER IN
THE GRIDS FOR THURS AND THURS NIGHT. COLD AIR ADVECTION SETS IN THURS
NIGHT...AND LONG- TERM GUIDANCE SUGGESTS THAT WEST TO NORTHWEST WINDS
WILL EXCEED 25 KT OVER THE OFFSHORE WATERS ON THURS NIGHT AND FRI.

00Z ECMWF GUIDANCE REMAINS BULLISH THAN THE 00Z GFS REGARDING THE
AMOUNT OF COLD AIR ADVECTION BEHIND THE FRONT THAN THE 00Z GFS...AND
LEANED TOWARDS THE ECMWF MOS FOR TEMPS. RAPID CLEARING IS EXPECTED
BEHIND THE FRONT ON FRI MORNING...WITH HIGHS FALLING TO ABOUT 10
DEGREES BELOW CLIMO. A FREEZE LOOKS LIKELY ON SAT MORNING FOR
INTERIOR LOCATIONS...WITH HIGHS ON SAT REMAINING ABOUT 5 DEGREES
BELOW CLIMO AS SURFACE RIDGING BUILDS OVER OUR AREA. 00Z ECMWF
MAINTAINS MORE TROUGHING DURING THE WEEKEND WHILE THE 00Z GFS
INDICATES A MORE PROGRESSIVE PATTERN THAT PLACES OUR REGION IN ZONAL
FLOW. LEANED ON ECMWF MOS...WHICH ARE SLIGHTLY BELOW LATE DEC CLIMO
FOR TEMPS NEXT WEEKEND AS A POTENTIAL REINFORCING DRY COLD FRONT
SURGES THROUGH OUR AREA ON SUN.

&&

.AVIATION...
VFR CONDITIONS WILL GIVE WAY TO MVFR CONDITIONS THIS AFTERNOON AS
MOISTURE INCREASES AHEAD OF AN APPROACHING COLD FRONT. IFR
CONDITIONS ARE EXPECTED IN LOW CLOUDS AND POSSIBLY SOME FOG
TONIGHT. BEST CHANCE FOR RAIN THIS AFTERNOON WILL BE AT SSI AS A
LINE OF SHOWERS AND A FEW EMBEDDED THUNDERSTORMS APPROACHES FROM
THE WEST.

&&

.MARINE...
SOUTHWEST WINDS AROUND 15 KNOTS WILL CONTINUE TODAY AHEAD OF AN
APPROACHING COLD FRONT. WINDS WILL INCREASE TO NEAR 20 KNOTS
FOR A FEW HOURS OVER THE OFFSHORE ZONES TONIGHT TO CREATE
MARGINAL SMALL CRAFT ADVISORY CONDITIONS DUE TO WINDS ONLY. SEAS
WILL BUILD TONIGHT IN RESPONSE TO THE INCREASE IN WINDS BUT PEAK
SEAS WILL REMAIN AT OR BELOW 6 FEET.

BENIGN CONDITIONS WILL PREVAIL LATE TUESDAY INTO THURSDAY...WITH
A MUCH STRONGER COLD FRONT MOVING THROUGH THURSDAY NIGHT WITH
SMALL CRAFT ADVISORY CONDITIONS LIKELY THURSDAY NIGHT AND FRIDAY.
GUSTS TO GALE FORCE WILL ALSO BE POSSIBLE.
