AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
252 AM EST TUE NOV 16 2010

.SYNOPSIS...04 UTC REGIONAL SURFACE ANALYSIS SHOWS A 1004 MB SURFACE
LOW CENTERED JUST INLAND ACROSS THE CENTRAL LOUISIANA GULF COAST.
THE QUASI-STATIONARY FRONTAL BOUNDARY EXTENDED FROM JUST OFF THE
TEXAS GULF COAST...THROUGH THE SURFACE LOW AND NORTHEASTWARD THROUGH
CENTRAL ALABAMA AND INTO NORTHEASTERN GEORGIA. DEWPOINT ANALYSIS
SHOWED 65 DEG F VALUES JUST OFFSHORE OF THE FLA PANHANDLE WITH A
NARROW CORRIDOR OF 70+DEG F DEWPOINTS FURTHER TO THE SOUTHWEST.
SEVERE WEATHER POTENTIAL WILL BE LARGELY TIED TO WHETHER THESE MORE
MOIST DEWPOINT VALUES CAN BE ADVECTED FURTHER INLAND ACROSS THE
REGION.

500 MB ANALYSIS FROM 00 UTC AND VAPOR IMAGERY SHOW A LARGE TROF
ACROSS THE CENTRAL CONUS WITH A POTENT SHORTWAVE WITHIN THIS LARGER
TROF ACROSS THE EASTERN RED RIVER VALLEY. THIS FEATURE WILL BE THE
MAIN DRIVER TO OUR WEATHER THROUGHOUT THE SHORT TERM. SOUNDING DATA
FROM 00 UTC AT KLIX SHOWS THE AIRMASS ONLY MARGINALLY UNSTABLE.
WHILE DEEP LAYER SHEAR ON THIS SOUNDING IS NEARING 55 KT...THE LOW
LEVEL FLOW IS RATHER WEAK.

&&

.SHORT TERM...(TODAY THROUGH THURSDAY).
THE MAIN FOCUS THIS MORNING IS ON THE EVOLUTION OF THE STORM SYSTEM
ACROSS THE CENTRAL GULF COAST. MODEL GUIDANCE CONTINUES TO BE IN
REASONABLY GOOD AGREEMENT THAT THE SURFACE LOW WILL LIFT
NORTHEASTWARD INTO THE TENNESSEE AND OHIO RIVER VALLEYS BY THIS
EVENING PULLING A COLD FRONT ACROSS THE FORECAST AREA AFTER SUNSET.
THE MAIN CONCERN IS WITH RESPECT TO SEVERE WEATHER POTENTIAL.
CURRENT RADAR DATA AND MESOANALYSIS WOULD ARGUE THAT THE SEVERE
THREAT WOULD BE LIMITED TODAY...AND ONLY NEAR THE IMMEDIATE COASTAL
AREAS. HOWEVER...THE MODELS ARE STILL WANTING TO PULL A NARROW
CORRIDOR OF MOIST AND UNSTABLE AIR INTO THE REGION...PERHAPS AS FAR
NORTH AS ALBANY BY THIS AFTERNOON. GIVEN THAT THE CONVECTIVE TRENDS
ACROSS THE MISSISSIPPI RIVER DELTA REGION HAVE BEEN QUITE SIMILAR TO
WHAT IS SHOWN IN OUR LOCAL WRF...I FIND IT DIFFICULT TO DISCOUNT
WHAT THE MODELS ARE PREDICTING. I DO HAVE SOME DOUBTS THAT WE WILL
BE ABLE TO DESTABILIZE ENOUGH FOR WIDESPREAD SEVERE ACTIVITY...BUT
GIVEN THE VERY FAVORABLE KINEMATICS WITH THIS SYSTEM (0-6 KM SHEAR
VALUES NEARING 60 KTS) IT WON'T TAKE MUCH INSTABILITY TO HAVE A FEW
STRONG TO SEVERE STORMS. AS USUAL FOR OUR REGION IN THE COOL
SEASON...THE FORECAST SEVERE POTENTIAL COMES DOWN TO
INSTABILITY...WITH THE SHEAR BEING MORE THAN SUFFICIENT. IT
LOOKS...BASED ON ALL AVAILABLE GUIDANCE...THAT THE SEVERE THREAT
COULD POSSIBLY EXTEND INLAND AS FAR AS THE US-82 CORRIDOR
(DOTHAN-ALBANY-TIFTON)...BUT BE THE GREATEST FROM THE FLORIDA BORDER
SOUTHWARD. THE DOMINANT STORM MODE STILL LOOKS TO BE INDIVIDUAL LINE
SEGMENTS WITH THE MAIN ACTIVITY...AND THUS A DAMAGING WIND EVENT. AS
FAR AS THE TORNADIC POTENTIAL GOES...IT LOOKS TO BE GREATEST EARLIER
IN THE EVENT WITH ANY DISCRETE CELLS MOVING INLAND AHEAD OF THE
DEVELOPING MAIN CONVECTIVE LINE. BUT GIVEN THE STRONG SHEAR...IT
WOULD NOT BE SURPRISING TO SEE A BRIEF TORNADO OR TWO IN THE
STRONGEST BOWING LINE SEGMENTS.

WITH ALL THAT SAID...ONE THING WE ARE QUITE CERTAIN ABOUT IS THAT IT
WILL RAIN...SO I SEE NO REASON TO DISCOUNT THE LOW GUIDANCE POPS FOR
VALUES NEAR 100 PERCENT...ESPECIALLY ALONG AND WEST OF A LINE FROM
TALLAHASSEE TO ALBANY. WILL CONTINUE TO INDICATE SEVERE STORMS IN
THE FORECAST IN THE COASTAL PANHANDLE AREAS IN THE PRE-DAWN AREAS
SPREADING INLAND AS PREVIOUSLY DISCUSSED THROUGHOUT THE AFTERNOON.

BY SUNSET TUESDAY SHOULD BE SEEING MOST OF THE ACTIVITY COMING TO AN
END WITH ANY LINGERING THREAT CONFINED TO THE SOUTHEAST FLORIDA BIG
BEND BEFORE MIDNIGHT. THEREAFTER...HIGH PRESSURE BUILDING OVER THE
REGION WILL KEEP CONDITIONS DRY...AND SOMEWHAT COOL (HIGHS ONLY IN
THE UPPER 60S TO LOWER 70S) INTO THURSDAY. SINCE THE INCOMING
AIRMASS IS MORE PACIFIC IN NATURE...TEMPERATURES THURSDAY MORNING
ARE ONLY EXPECTED TO BE IN THE UPPER 30S TO NEAR 40...SO NO FROST IS
ANTICIPATED AT THIS TIME AS THE HIGH CENTER BUILDS DIRECTLY OVER THE
REGION.

.LONG TERM...(THURSDAY NIGHT THROUGH TUESDAY).
THE LONG TERM PERIOD LOOKS TO REMAIN VERY QUIET AND TRANQUIL. MODEL
GUIDANCE BETWEEN THE 16/00Z GFS AND EURO AGREES THAT BY
FRIDAY...RIDGING AT THE SURFACE AND ALOFT WILL BEGIN TO BUILD
OVER...OR JUST TO THE EAST OF THE REGION AND REMAIN IN THIS POSITION
THROUGH THE LONG TERM PERIOD. THIS WILL RESULT IN SLIGHTLY WARMER
TEMPERATURES EACH DAY...BEGINNING ON SATURDAY AND CONTINUING INTO
TUESDAY. HIGH TEMPERATURES AT THE BEGINNING OF THE PERIOD WILL BE
ABOUT NEAR CLIMATOLOGY...AND WARMING TO ABOUT +7 RELATIVE TO
CLIMATOLOGY BY MONDAY. A COUPLE OF COOL MORNINGS ARE EXPECTED
THROUGH SUNDAY MORNING...BEFORE OVERNIGHT MINS SETTLE INTO THE LOW
TO MID 50S FOR THE START OF THE WORK WEEK.

&&

.AVIATION...LIGHT TO MODERATE SHOWERS WITH GUSTY WINDS WILL DOMINATE
THE TERMINALS OVERNIGHT...WITH ONLY PERIODS OF MVFR CONDITIONS
EXPECTED. TOWARDS SUNRISE TO THE WEST...AND LATER IN THE MORNING AND
EARLY AFTERNOON TO THE EAST...HOWEVER...HEAVIER SHOWERS WITH SOME
POSSIBLE STRONG TO SEVERE THUNDERSTORMS ARE EXPECTED TO DEVELOP AND
IMPACT THE TERMINALS FROM SOUTHWEST TO NORTHEAST. THESE STORMS WILL
BE CAUSED BY A RAPIDLY DEVELOPING LOW PRESSURE SYSTEM WHICH WILL
MOVE NORTHEASTWARD FROM THE LOUISIANA COASTLINE TOWARDS THE NORTH
GA/AL BORDER BY LATER THIS AFTERNOON. THESE SHOWERS AND STORMS WILL
THEN COME TO AN END FROM WEST TO EAST AS THE LOW'S COLD FRONT SWINGS
THROUGH THE REGION.

&&

.MARINE...STRONG SOUTHERLY FLOW AHEAD OF THE LOW PRESSURE SYSTEM
WILL CREATE ADVISORY CONDITIONS ACROSS THE ENTIRE MARINE AREA.
THOUGH SCA CONDITIONS HAVE NOT QUITE REACHED THE FAR EASTERN
LEGS...ANALYSIS AND MODEL DATA SHOW THAT THE WIND CRITERIA WILL SOON
BE MET. WITH THE STRONG SOUTHERLY FLOW...SEAS WILL BUILD TO 7 TO 9
FEET WELL OFFSHORE AND GENERATE LARGE SURF THAT WILL BEGIN TO IMPACT
THE FLORIDA PANHANDLE BEACHES...PARTICULARLY BETWEEN PANAMA CITY AND
DESTIN LATER TODAY. IT LOOKS LIKE THESE BREAKERS WILL AVERAGE
BETWEEN 4 AND 6 FEET IN HEIGHT...WITH LOCALLY HIGHER SURF POSSIBLE.
FOR THAT REASON...WILL ISSUE A HIGH SURF ADVISORY FOR COASTAL BAY
AND WALTON COUNTIES. AFTER THE PASSAGE OF THE COLD FRONT THIS
EVENING...WINDS WILL SHIFT TO OFFSHORE AND GRADUALLY DIMINISH AS
HIGH PRESSURE BUILDS OVER THE AREA. ASIDE FROM A BRIEF INCREASE IN
WINDS THURSDAY NIGHT AS STRONG HIGH PRESSURE BUILDS DOWN THE
MISSISSIPPI RIVER VALLEY...WINDS AND SEAS ARE EXPECTED TO REMAIN
BELOW HEADLINE CRITERIA AFTER TONIGHT.

&&

.FIRE WEATHER...THERE WILL BE NO CONCERNS FOR TODAY WITH PLENTY OF
SHOWERS AND THUNDERSTORMS KEEPING AFTERNOON RELATIVE HUMIDITIES VERY
HIGH. ON WEDNESDAY...COOLER AND DRIER AIR WILL BUILD IN BEHIND THE
COLD FRONT...AND RELATIVE HUMIDITIES COULD APPROACH RED FLAG LEVELS
ACROSS INTERIOR PORTIONS OF THE FL BIG BEND AND PANHANDLE. IF
CONDITIONS APPEAR CLOSE ENOUGH...MAY CONSIDER A FIRE WEATHER WATCH
FOR PARTS OF THE AREA.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST ALABAMA...
SOUTHWEST AND SOUTH CENTRAL GEORGIA...AND THE FLORIDA BIG BEND
AND PANHANDLE...AND ADJACENT COASTAL WATERS.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR THE FORECAST
AREA INTO TUESDAY...

.DAY ONE...TONIGHT...

A LOW PRESSURE AREA WILL BEGIN TO TAKE SHAPE ACROSS THE WESTERN GULF
REGION THIS EVENING AND LIFT NORTHWARD INTO THE TENNESSEE RIVER
VALLEY ON TUESDAY MORNING. AS THIS LOW PRESSURE AREA MOVES
NORTHWARD...IT WILL DRAG A COLD FRONT EASTWARDS. AHEAD AND ALONG
THIS FRONT...SHOWERS AND THUNDERSTORMS WILL CONTINUE TO OVERSPREAD
THE FLORIDA PANHANDLE AND SOUTHEAST ALABAMA...BEFORE MOVING EAST
ACROSS THE REST OF THE AREA INTO TUESDAY MORNING. SOME STORMS MAY
BE STRONG TO POSSIBLY SEVERE WITH DAMAGING GUSTS OVERNIGHT...
ESPECIALLY OVER THE COASTLINES AND ADJACENT WATERS. THE POTENTIAL
FOR SEVERE WEATHER WILL INCREASE TOWARD DAYBREAK WITH SOME STORMS
CAPABLE OF PRODUCING DAMAGING WINDS AND POSSIBLY AN ISOLATED
TORNADO.

WINDS AND SEAS WILL NOTICEABLY INCREASE OVERNIGHT. A SMALL CRAFT
ADVISORY IS IN EFFECT.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY...

SHOWERS AND THUNDERSTORMS ARE EXPECTED TO BE ONGOING AT DAYBREAK
TUESDAY...ESPECIALLY TO THE WEST OF THE APALACHICOLA RIVER...AS A
STORM SYSTEM MOVES NORTHEASTWARD THROUGH THE TENNESSEE VALLEY.
DEPENDING ON THE EXACT STRENGTH AND TRACK OF THIS STORM SYSTEM...
STRONG TO SEVERE STORMS COULD BE POSSIBLE THROUGH TUESDAY MORNING
WEST OF...AND THROUGH TUESDAY AFTERNOON EAST OF THE APALACHICOLA
RIVER. THE MAIN THREAT WILL CONTINUE TO BE DAMAGING WINDS. AFTER
THE FRONT EXITS EAST OF THE AREA BY TUESDAY NIGHT...HIGH PRESSURE
AND DRIER AIR WILL FILTER IN FOR THE REST OF THE WORK WEEK.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION MAY BE NEEDED AFTER MIDNIGHT AND ON TUESDAY.
