Area forecast discussion, May 26, 8:34 PM EDT, 49 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
834 PM EDT THU MAY 26 2011

.SYNOPSIS...
A LOW PRESSURE SYSTEM WILL PUSH A WEAKENING COLD FRONT ACROSS THE
CAROLINAS THROUGH FRIDAY MORNING. THE FRONT IS EXPECTED TO STALL AND
WASH OUT OVER THE REGION FRIDAY AFTERNOON. SUMMER LIKE WEATHER WILL
RETURN ON SATURDAY AND LINGER INTO EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH FRIDAY/...
CONVECTION HAS MORE OR LESS CONSOLIDATED INTO A BROKEN SQUALL LINE
THAT IS BISECTING THE CWFA ATTM. THIS TRANSITION TO A MORE OUTFLOW-
DOMINATED MODE HAS SEEN A TRANSITION FROM A MAINLY LARGE HAIL THREAT
TO A DOWNBURST SITUATION. ALTHOUGH ISOLATED MARGINAL LARGE HAIL WILL
REMAIN POSSIBLE...DAMAGING WINDS...WITH THE POSSIBILITY OF A HANDFUL
OF HIGH-END EVENTS (AS HAS ALREADY OCCURRED OVER ELBERT COUNTY GA)
WILL BE POSSIBLE. POPS HAVE BEEN RAMPED UP TO HIGH LIKELY ACROSS ALL
BUT ABOUT THE EASTERN 1/4 OF THE CWFA. EAST OF THERE THE SITUATION
IS A BIT MORE COMPLICATED. THE LINE IS MOVING SLOWLY...AND WILL BE
BATTLING DIMINISHING INSTABILITY AND WEAKENING SHEAR. THEREFORE...
WILL KEEP POPS IN THE SOLID CHANCE RANGE FOR NOW.

PREVIOUS DISCUSSION...

AT 1730Z...AN UPPER TROF WILL PROGRESS ACRS THE OH/TN VLYS TONIGHT
AND LIFT NE THRU THE APPALACHIANS ON FRIDAY. THE FORCING ASSOCIATED
WITH THE APPROACH OF THE TROF WILL BE STRONGEST FROM LATE THIS AFTN
WELL INTO THE OVERNIGHT HOURS. THE GFS AND NAM AGREE ON DECENT UPPER
DIVERGE AS WELL DURING THAT TIME FRAME. SHEAR AND INSTBY WILL BE
ENUF TO SUPPORT CONVECTION THRU THE NIGHT. THERE IS CURRENTLY A SVR
TSTM WATCH TO OUR WEST...INCLUDING FOUR NC COUNTIES (SEE WCNGSP).
CONVECTION SO FAR HAS BEEN FAIRLY DISCRETE SUPERCELLS. THE MESOSCALE
MODELS SEEM TO AGREE ON THIS ACTIVITY MORPHING INTO A MULTI-CELL
LINE AS IT ENTERS THE CWA AROUND 20-22Z TIME FRAME...THEN BANDS OF
CONVECTIVE SEGMENTS WELL INTO THE OVERNIGHT. HAVE ADJUSTED POPS
ACCORDINGLY. STILL THINK ANOTHER ROW OF WATCHES WILL BE ISSUED SOME
TIME LATER THIS AFTN AS THE CONVECTION ORGANIZES. NOT SURE HOW WELL
THE CONVECTION WILL HOLD TOGETHER DURING THE WEE MORNING HOURS.
THINK CONVECTIVE THREAT WILL GRADUALLY DECREASE THRU DAYBREAK. TEMPS
OVERNIGHT WILL BE MILD WITH THE CLOUDS AND MIXING ASSOCIATED WITH
THE APPROACH OF THE COLD FRONT.

ON FRIDAY...THE FRONT STALLS OVER THE AREA...WITH PLENTY OF
LINGERING MOISTURE. UPPER SUPPORT SHOULD CONTINUE THRU 18Z AS THE
TROF PIVOTS TO NEGATIVE TILT AND SLOWS. HAVE BLENDED IN MODEL
CONSENSUS ON POPS...RESULTING IN LIKELY THRU THE AFTN (ESPECIALLY
ERN HALF OF THE CWA). SHEAR WEAKENS AND UPPER DIVERGE
DECREASES...BUT INSTBY SHUD INCREASE WITH HEATING TO 1000-1500 J/KG
ONCE AGAIN ACRS THE PIEDMONT. SO DO EXPECT SCATTERED TO NUMEROUS
TSTMS...BUT SEVERE THREAT WILL BE MODEST. NEW SPC DAY 2 OUTLOOK IS
JUST SEE TEXT. THE MET AND MAV IN DISAGREEMENT ON MAX TEMPS. WENT
WITH WARMER MAV BASED ON CONTINUITY.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
AS OF 230 PM THURSDAY...THE SHORT RANGE PERIOD WILL BEGIN FRIDAY
NIGHT WITH ONGOING DIURNAL CONVECTION. EXPECT NUMEROUS COVERAGE TO
PERSIST ACROSS THE EASTERN PORTION OF THE FA FOR A FEW HOURS BEFORE
DIMINISHING IN THE LOSS OF HEATING AND MOVING FURTHER EAST. SATURDAY
WILL SEE THE TRANSITION PERIOD BETWEEN THE DEPARTING REMNANT UPPER
TROF AND RIDGE BEGINNING TO BUILD IN FROM THE SW. EXPECT STILL
MODERATE INSTABILITY TO DEVELOP ACROSS AREAS TO THE SOUTH AND EAST.
THERE WILL BE LESS CONVECTIVE INHIBITION FURTHER TO THE EAST IN THE
BETTER INSTABILITY BUT WITH WEAK WIND PROFILES THROUGH THE
COLUMN...COVERAGE WILL BE ISOLATED AT BEST. ACROSS THE
MOUNTAINS...MODEL SOUNDING SHOW A MORE PROMINENT INVERSION AND CAP
AT AROUND 700 MB...BUT SOME SOUTHERLY UPSLOPE FLOW SHOULD HELP KICK
OFF MORE SCATTERED RIDGE TOP CONVECTION. SEVERE THREAT WILL BE
MINIMAL AT BEST WITH HIGH FREEZING LEVELS...BUT DRY AIR ALOFT COULD
HELP PRODUCE A DAMAGING WIND GUST OR TWO. ANY LINGERING SHOWERS AND
STORMS WILL DISSIPATE QUICKLY AFTER SUNSET.

INTO SUNDAY...THE THE RIDGE ALOFT WILL QUICKLY ASSERT ITSELF OVER
THE SOUTHEAST WITH A VERY PROMINENT UPPER ANTICYCLONE DEVELOPING
OVER THE SOUTHERN APPALACHIANS. CONVECTION WILL BECOME EVEN MORE
LIMITED AND WE WILL ONLY CARRY SLIGHT CHANCES ALONG THE ESCARPMENT
AND THE RIDGE TOPS FOR THE NC MOUNTAINS. TEMPS WILL RUN ABOUT 6
DEGREES ABOVE NORMAL ON SATURDAY AND WILL INCREASE INTO SUNDAY WITH
THE STRENGTHENING UPPER RIDGE. SUNDAY HIGHS WILL INCREASE BACK INTO
THE UPPER 80S OUTSIDE THE MOUNTAINS...WITH MID 80S EXPECTED IN THE
MOUNTAIN VALLEYS.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AS OF 200 PM THURSDAY...THE MEDIUM RANGE GUIDANCE IS IN AGREEMENT
THAT AN UPPER LEVEL ANTICYCLONE WILL DOMINATE THE WEATHER OVER THE
SOUTHERN APPALACHIANS AND WESTERN CAROLINAS THROUGH MIDWEEK. THE
UPPER HIGH IS FORECAST TO RETROGRADE INTO THE SOUTHERN PLAINS BY LATE
NEXT WEEK WHICH PAVES THE WAY FOR A BACKDOOR COLD FRONT TO MOVE
THROUGH IN THE WED NIGHT THU TIMEFRAME. MON THROUGH WED WILL FEATURE
GENERALLY CLEAR CONDITIONS...HOT TEMPERATURES AND SUPPRESSED
CONVECTIVE CHANCES DUE TO SYNOPTIC SCALE SUBSIDENCE OVER THE REGION.
MAX TEMPS WILL RUN A GOOD 10+ DEGREES ABOVE CLIMO. WILL ALLOW FOR
SOME LOW CHANCE POPS AND COOLER TEMPS FOR THU WITH THE ARRIVAL OF
THE BACKDOOR FRONT. STAYED CLOSE TO HPC GUIDANCE FIELDS.

&&

.AVIATION /01Z FRIDAY THROUGH TUESDAY/...
AT KCLT...MAIN CONCERN FOR THE OVERNIGHT IS THE CONVECTIVE
POTENTIAL. CONVECTION HAS FIRED OVER THE FOOTHILLS/UPSTATE SC IN
ADVANCE OF THE MAIN COLD FRONT-ASSOCIATED CONVECTION. HOWEVER...THE
FOOTHILLS ACTIVITY IS MAKING VERY LITTLE PROGRESS TO THE EAST. ONCE
THE REMNANT STORMS OVER THE NC MTNS/NORTH GA CATCH UP WITH IT...THE
ENTIRE AREA OF CONVECTION SHOULD BEGIN A MORE EASTWARD PROGRESSION.
HOWEVER...IT VERY WELL MAY BE IN A DIMINISHED STATE IN TERMS OF
COVERAGE AND INTENSITY. ANYWAY...I DIDN/T FEEL COMFORTABLE WITH
INCLUDING A TEMPO OR CATEGORICAL MENTION OF CONVECTION ATTM...BUT
WILL CONTINUE TO EVALUATE THE NEED TO UP THE ANTE IN FUTURE
AMENDMENTS. OTHERWISE...WE ARE EXPECTING MVFR CIGS TO DEVELOP IN
THE MOIST SW FLOW AROUND SUNRISE. SOME FOG WILL ALSO BE POSSIBLE...
BUT WILL LARGELY DEPEND UPON HOW MUCH RAIN FALLS IN THE AREA.
COVERAGE OF CONVECTION WILL INCREASE AGAIN BY FRIDAY AFTERNOON.

ELSEWHERE...A LINE OF SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE
TERMINALS EARLY IN THE PERIOD...TAPERING OFF TO SHOWERS BY MIDNIGHT.
VISBY SHOULD GENERALLY BE MVFR. HOWEVER...BRIEF PERIODS OF IFR WILL
BE POSSIBLE WITH HEAVIER SHOWERS/STORMS. SHOWERS WILL DECREASE IN
COVERAGE LATER TONIGHT. HOWEVER...VISBY SHOULD BEGIN TO DIMINISH
OWING TO THE WET GROUND. EXTENSIVE CLOUD COVER IS EXPECTED TO
PREVENT CONDITIONS FROM CRASHING TOO STRONGLY...BUT AT LEAST MVFR
VISBY CAN BE EXPECTED...WITH IFR LIKELY IN THE MTN VALLEYS. IN
ADDITION...AN MVFR STRATUS DECK IS EXPECTED TO DEVELOP AROUND
SUNRISE IN THE MOIST SW FLOW. CONVECTION WILL EXPAND IN COVERAGE
ONCE AGAIN FRIDAY AFTERNOON.

OUTLOOK...CLUSTERS OF SHRA/TSRA WILL LINGER ACROSS THE REGION FRIDAY
EVENING. DRY AND WARM AIR MASS IS EXPECTED TO SETTLE OVER THE
FORECAST AREA THIS WEEKEND AND WILL REMAIN INTO THE MID WEEK.
DIURNAL SHRA/TSRA ARE POSSIBLE EACH AFTERNOON AND EVENING ACROSS THE
MTNS AND ADJACENT FOOTHILLS.
