Area forecast discussion, Oct 26, 3:27 PM EDT, 2 hours 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
327 PM EDT TUE OCT 26 2010

.SYNOPSIS...
AN ACTIVE COLD FRONT WILL MOVE INTO THE WESTERN CAROLINAS AND
NORTHEAST GEORGIA TONIGHT...THEN PUSH EAST OF THE FORECAST AREA BY
WEDNESDAY NIGHT. CANADIAN HIGH PRESSURE WILL THEN BUILD IN FOR THE
WEEKEND.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
TORNADO WATCH ISSUED FOR THE TN BORDER COUNTIES OF NC...EXTREME
WESTERN NC...AND EXTREME NE GA UNTIL 10 PM.

AT 1830Z...THE SFC COLD FRONT WAS LOCATED ACROSS NRN MS AND
MIDDLE TN. A STRONG BAND OF TS/SHRA HAS DEVELOPED ALONG AND AHEAD OF
THE COLD FRONT...MOVING EAST AT 30 KTS. AS SECONDARY BAND OF
CONVECTION HAS DEVELOP ALONG AND BEHIND A GRAVITY WAVE ACROSS NRN
AL/E TN.  THE ENVIRONMENT AHEAD OF THE LINE FEATURES SBCAPE BETWEEN
500-1000 J/KG WITH 0-1 KM SRH BETWEEN 300-500 M2/S2. BASED ON THE
LATEST TIMING OF THE SQUALL LINE AND GRAVITY WAVE CONVECTION OVER
TN...DEEP CONVECTION MAY REACH OR DEVELOP OVER THE WESTERN NC MTNS
AS EARLY AS 21Z TO 24Z. AS THE LINE REACHES THE SOUTHERN
APPALACHIANS IT WILL LIKELY SLOW AS IT OUTPACES IT/S ASSOCIATED COLD
POOL AND SFC COLD FRONT. THE PRIMARY PERIOD FOR SVR WEATHER WILL
OCCUR AS THE LEADING LINE OF CONVECTION REACHES THE TN/NC LINE THIS
EVENING. BASED ON THE ENVIRONMENT...THESE STORMS MAY PRODUCE
DAMAGING WINDS AND POSSIBLY A BRIEF TORNADO. IN ADDITION...LLVL FLOW
ALONG AND AHEAD OF THE GRAVITY WAVE AND COLD FRONT WILL YIELD AN
INCREASE IN WINDS ACROSS THE MTNS THROUGH THIS EVENING AND INTO THE
EARLY MORNING HOURS. I WILL EXPAND THE WIND ADVISORY ACROSS THE MTNS
UNTIL 3 AM.

LATE TONIGHT...DEEP LOW PRESSURE OVER MN WILL MOVE NORTH INTO
CANADA...RESULTING IN A DECREASE IN WIDESPREAD FORCING AND DEEP
SOUTHWEST FLOW. AS A RESULT...THE SFC FRONT MAY SLOW OR TEMPORARILY
STALL OVER THE FORECAST AREA TONIGHT. THE 12Z GFS INDICATES THE
FRONTOGENESIS WILL PIVOT OVER THE MTNS...STRONGEST OVER THE NRN
MTNS...AND GRADUALLY WEAKEN. ORGANIZATION AND STORM STRENGTH WILL
LIKELY DECREASE OVERNIGHT. HOWEVER...4 KM WRF INDICATES THAT A FEW
DISCRETE LINE SEGMENTS WILL EXIST EAST OF THE MTNS...SUPPORTED BY
STRONG LLVL SHEAR AND WEAK CAPE. I WILL INDICATE CATE POPS ACROSS
THE MTNS AND TIME LIKELY POPS ACROSS THE FOOTHILLS AND PIEDMONT. MIN
TEMPERATURE WILL REMAIN NEARLY 20 DEGREES ABOVE NORMAL...NEAR RECORD
HIGH MINIMUMS.

WEDNESDAY...TEMPERATURES WILL STEADILY WARM AFTER SUNRISE...PEAKING
IN THE U70S TO L80S EAST OF THE MTNS WITH DEWPOINTS MID TO U60S.
AFTERNOON CAPE VALUES SHOULD RANGE FROM 300-800 J/KG WITH HIGH SWEAT
AND HELICITY VALUES. STORMS WILL DEVELOP ALONG THE COLD FRONT AND
TRACK NE. BASED ON THE HIGH SHEAR LOW CAPE ENVIRONMENT...LINE
SEGMENTS OR STORM CLUSTERS MAY BECOME THE FAVORED STORM MODES. THE
PRIMARY THREAT WILL REMAIN WIND...WITH A BRIEF TOR POSSIBLE.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AS OF 245 PM TUESDAY...THE SFC FRONT WILL CROSS THE REGION WED
NIGHT. THE NAM LLVL WINDS INCREASE INTO THE 50+ KT RANGE OVER THE
FOOTHILLS AND PIEDMONT AHEAD OF THE BNDRY. WITH THE INCREASING LLVL
CONVERGENCE...PCPN INCREASES ACROSS THE PIEDMONT BEFORE FINALLY
MOVING OUT OF THE FA SOMETIME AFTER MIDNIGHT. I/VE UPPED POPS INTO
THE HIGH CHANCE RANGE...BUT IF THE SLOWER AND MORE DYNAMIC TREND
CONTINUES...HIGHER POPS WILL BE IN ORDER WED EVENING. ATTN THE
INSTABILITY DOESN/T LOOK TO BE ALL THAT HIGH. BUT WITH DEWPOINTS
STILL WELL INTO THE 60S...THE BUFKIT SOUNDINGS ARE SHOWING A SMALL
AMOUNT OF CAPE. SO A MODEST SEVERE THREAT WILL CONTINUE INTO THE
EVENING HOURS...ESPECIALLY ACROSS THE WESTERN PIEDMONT. THE LLVL
FLOW QUICKLY VEERS TO THE WEST IN THE EARLY EVENING...WHICH SHOULD
CONFINE THE SEVERE THREAT TO A FEW SMALL AREAS OF STRAIGHT LINE
WIND DAMAGE.

THURSDAY WILL BE A MUCH DRIER DAY. DOWNSLOPE FLOW WILL WARM TEMPS
INTO THE M-U70S OVER THE FOOTHILLS AND PIEDMONT...WITH 60S IN THE
MTNS. THE GRADIENT TIGHTENS ACROSS THE THE MTNS THU NIGHT AS A
STRONG SHORT WAVE MOVES INTO THE MID ATLANTIC STATES. USING A BLEND
OF THE MET/MAV AND COOP MOS...I HAVE MIN TEMPS FALLING BELOW
FREEZING IN PART OF THE NC MTNS. FRIDAY WILL BE CLEAR AND
COOLER...THOUGH MAX TEMPS WILL STILL ONLY BE A DEGREE OR TWO BELOW
NORMAL.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AS OF 145 PM TUESDAY...THE EXT RANGE CONTINUES TO SHOW GOOD
CONTINUITY BTW MODEL RUNS AND OVERALL RUN TO RUN CONSISTENCY. THE
LARGE WAVE PATTERN IS WELL AGREED UPON UNTIL THE END OF THE PERIOD
WHEN SIGNIFICANT DYNAMIC DIFFERENCES ARISE. IN THE MEANTIME...EXPECT
THE CP SFC HIGH TO SLOWLY TRANSITION EAST ACROSS THE CWFA AND BY MON
THE CENTER SHOULD BE OFFSHORE ALLOWING SOME MEASURE OF GOM MOISTURE
ADV INTO THE AREA. THE 12Z GFS PUSHES A BACKDOOR COLD FRONT INTO THE
NRN ZONES SUN NIGHT...HOWEVER THIS FEATURE IS NOT SUPPORTED BY THE
00Z ECMWF AND LOOKS TO BE VERY DRY IN ANY REGARD. WITH UNCERTAINTY
IN THE LARGE SCALE SYNOPTIC PATTERN MON...WILL NOT JUMP ON THE
MOISTER GFS SOLN ATTM AND WILL GO WITH ONLY A SMALL AREA OF SLT
CHC UPSLOPE SHOWERS ACROSS THE SW MTNS...WITH POPS BECOMING MORE
WIDESPREAD TUE THEN GOING TO CHC ACROSS THE WRN ZONES AS MOISTURE
LEVELS WILL INCREASE. LITTLE IN THE WAY OF INSTABILITY SHOULD BE
REALIZED TUE WITH THE MIXED POLAR AIRMASS SLOW TO MODIFY...EVEN
CONSIDERING THE MORE DYNAMIC AND WARM ADVECTIVE GFS...SO TSTM
MENTION HAS BEEN LEFT OUT OF THE FCST. MAX TEMPS WILL START OUT
AROUND NORMAL SAT AND GRADUALLY BECOME A FEW DEGREES ABOVE NORMAL
THROUGH THE PERIOD. MINS WILL FOLLOW THE SAME TREND WITH MOISTURE
INCREASING THROUGH THE COLUMN.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
AT KCLT...MVFR CEILINGS MAY REMAIN UNTIL 19Z...THEN CEILINGS WILL
LIFT TO VFR WITH GUSTY SOUTHWEST WINDS. WIND GUSTS ARE FORECAST TO
CONTINUE UNTIL SUNSET...WITH SOUTHWEST WINDS BETWEEN 10 TO 15 KTS
CONTINUING THROUGH THE REST OF THE NIGHT. FORECAST SOUNDINGS
INDICATE THAT INCREASING LLVL FLOW WILL BRING DEEP MOISTURE ACROSS
THE PIEDMONT OVERNIGHT. BOTH THE SOUNDINGS AND MOS GUIDANCE SUPPORTS
A MENTION OF MVFR CEILINGS...AROUND 015 KFT...DEVELOPING DURING THE
PRE DAWN HOURS ALONG WITH DZ OR RA. MVFR CEILINGS SHOULD LIFT AFTER
SUNRISE...WITH GUSTS AROUND 20 KTS REDEVELOPING BY 15Z.

ELSEWHERE ACRS THE FA...PRE FRONTAL CONVECTION WILL INCREASE ACROSS
THE WESTERN CAROLINAS THROUGH 6Z...ESPECIALLY ACROSS THE EAST FACING
MTNS. GUSTY SOUTHWEST WINDS MAY LINGER THROUGH THE EARLY MORNING
HOURS. FORECAST SOUNDINGS INDICATE THAT INCREASING LLVL FLOW WILL
BRING DEEP MOISTURE ACROSS THE REGION OVERNIGHT. BOTH THE SOUNDINGS
AND MOS GUIDANCE SUPPORTS A MENTION OF MVFR TO IFR CEILINGS
DEVELOPING DURING THE PRE DAWN HOURS ALONG WITH DZ OR RA. LOW CEILINGS
SHOULD LIFT AFTER SUNRISE...WITH GUSTS AROUND 20 KTS REDEVELOPING BY
15Z.

OUTLOOK...CONVECTION AND CEILINGS MAY LINGER INTO WEDNESDAY EVENING
EAST OF THE MTNS. DRY HIGH PRESSURE WILL BUILD OVER THE REGION ON
THURSDAY AND REMAIN THROUGH MUCH OF THE WEEKEND.
