Area forecast discussion, May 27, 2:48 PM EDT, 1 hour 48 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
248 PM EDT FRI MAY 27 2011

.SYNOPSIS...
A STATIONARY FRONT WILL CONTINUE TO DISSIPATE OVER THE REGION
THROUGH SATURDAY. AN UPPER LEVEL RIDGE WILL BUILD OVER OUR REGION
AND CREATE SUMMER LIKE WEATHER THROUGH MUCH OF NEXT WEEK. THE NEXT
FRONTAL BOUNDARY IS EXPECTED TO APPROACH FROM THE NORTH LATE IN THE
WEEK.

&&

.NEAR TERM /THROUGH SATURDAY/...
AT 1830Z...A SVR TSTM WATCH REMAINS IN EFFECT FOR THE ERN FRINGE
COUNTIES EAST OF I-77 UNTIL 7 PM. NUMEROUS SHWRS AND TSTMS EXPECTED
TO CONTINUE TO DEVELOP ACRS THE FA THRU THE AFTN. BEST SHEAR/INSTBY
AND UPPER SUPPORT HAVE ALL SHIFTED EAST OF THE CWFA. SO MOST
CONVECTION WILL BE GARDEN VARIETY. HOWEVER...ISOLD SVR TSTMS
PRODUCING QUARTER-SIZED HAIL AND/OR GUSTS TO 60 MPH CANNOT BE RULED
OUT ACRS THE PIEDMONT THRU THE AFTN. TEMPS ARE STILL COOL WHERE RAIN
HAS FALLEN. VERY MOIST LLVLS HAVE RESULTED IN STUBBORN STRATUS ACRS
MUCH OF THE UPSTATE AND NC FOOTHILLS NEAR THE BLUE RIDGE. SO TEMPS
ARE STILL IN THE UPR 60S TO LWR 70S ACRS MUCH OF THE AREA.

TONIGHT...SHORTWAVE WILL EXIT THE AREA AS AN UPPER TROF LIFTS NE.
UPPER HEIGHTS WILL RISE IN EARNEST THRU THE NEAR TERM...RESULTING IN
DROP IN POPS THRU THE NGT. WITH THAT SAID...LLVLS REMAIN VERY MOIST
AND LINGERING INSTBY WILL REMAIN ALONG I-77 CORRIDOR THRU THE NGT.
STORMS HAVE BEEN ORGANIZING INTO SLOW-MOVING LINES ORIENTED N-S ACRS
THE CAROLINAS AND ERN GA. THE NAM AND GFS AGREE ON THE AXIS OF
1.5-1.75" PWATS REMAINING EAST OF THE FA. AND THE WRN-MOST TSTM
CLUSTERS HAVE MORE MOVEMENT. SO THINK FLOOD THREAT IS STILL TOO LOW
TO WARRANT A FLASH FLOOD WATCH ATTM. TRENDS IN CONVECTION TO OUR
SOUTH WILL BE MONITORED INTO THE EVENING. OTHERWISE...CLOUDS ARE
EXPECTED TO FILL IN WITHIN LIGHT MOIST S FLOW. TEMPS WILL REMAIN
MILD IN THE 50S MTNS AND 60S PIEDMONT.

SATURDAY...DESPITE RIDGE BUILDING IN FROM THE WEST...LLVL MOISTURE
WILL LINGER ACRS THE AREA IN A SLY FLOW. FCST SNDGS SHOW 1000-2000
J/KG OF CAPE WITH DAYTIME HEATING. SHEAR WILL BE VERY WEAK...AND
LLVL FOCUS FOR CONVECTION WILL BE WEAK AS WELL. WITH SUBSIDENCE
DOMINATING...THINK THERE WILL BE JUST ISOLD-SCT CONVECTION DUE TO
WEAK UPSLOPE AND MTN-TOP CONVERGENCE. THE LOW-END CHC POP LOOKS
GOOD. THE 925 MB FLOW WILL BACK TO SELY...AND THIS MAY RESULT IN
STUBBORN STRATUS WELL INTO THE DAY. BUT STILL THINK CLOUDS SHUD
SCATTER OUT AND ALLOW FOR TEMPS TO REBOUND INTO THE MID 80S.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF 215 PM FRIDAY... MODELS ARE CONSISTENT IN DEVELOPING A DEEP
LAYER RIDGE OVER THE EASTERN U.S. DURING THE WEEKEND WITH THE CENTER
ENDING UP NORTH OF THE AREA BY LATE SUNDAY. AT THE SURFACE...THIS
WILL ALLOW THE SUBTROPICAL RIDGE OVER THE WESTERN ATLANTIC TO BUILD
WESTWARD INTO THE WESTERN CAROLINAS AND SOUTHERN APPALACHIANS. EVEN
WITH THE DEEP LAYER RIDGING...THE FORECAST IS NOT WITHOUT A COUPLE
COMPLICATIONS. MODELS INDICATE THAT WITH SE FLOW DEVELOPING OVER THE
AREA BY EARLY SUNDAY THAT LOW LEVEL MOISTURE WILL INCREASE UNDER THE
INVERSION RESULTING IN SOME LOW CLOUDINESS EARLY SUNDAY OVER A LARGE
PORTION OF THE FORECAST AREA. WITH HEATING...EXPECT THE CLOUDS TO
LIFT/SCATTER BY EARLY AFTERNOON. MODEL SOUNDINGS INDICATE THAT CIN
COULD BE OVERCOME IN A FEW PLACES ALLOWING FOR SOME ISOLATED
SHOWERS/THUNDERSTORMS OVER THE PIEDMONT. WITH THE SE/UPSLOPE
FLOW...WIDELY SCATTERED SHOWERS/THUNDERSTORMS ARE EXPECTED OVER THE
FAVORED MOUNTAIN AREAS. ANY CONVECTION WILL BE HIGHLY DIURNAL IN
NATURE AND DISSIPATE QUICKLY SUN EVENING. LOOKS LIKE MOISTURE WILL
BE LESS ON MON...BUT WITH SE FLOW SOME WIDELY SCATTERED
SHOWERS/THUNDERSTORMS WILL BE POSSIBLE OVER THE MOUNTAINS DURING THE
AFTERNOON. VERY WARM TEMPS WILL BE THE RULE WITH MAX TEMPS A GOOD
10+ DEGREES ABOVE CLIMO.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF NOON FRIDAY...A DOMINANT RIDGE WILL REMAIN ACROSS THE SRN
STATES TUE THROUGH WED...WITH THE RIDGE CENTER RETROGRADING FROM THE
OH VALLEY TO TX THROUGH THE PERIOD. UNSEASONABLY HOT CONDITIONS WILL
PERSIST. LINGERING LOW LEVEL MOISTURE UNDER THE RIDGE COULD ALLOW
ISOLATED TO SCATTERED DIURNAL MTN CONVECTION TO DEVELOP EACH DAY.
MODEL DIFFERENCES BEGIN TO SHOW UP THU AS AN ERN CANADIAN LOW DIGS
TOWARD NEW ENGLAND. THE GFS IS FASTER THAN THE ECM TO LOWER HEIGHTS
ALONG THE EAST COAST. A MODEL BLEND OF THE TWO TOWARD ENSEMBLE
VALUES WILL BE PREFERRED. THIS SHOULD ALLOW A BACKDOOR COLD FRONT TO
REACH THE FORECAST AREA THU INTO FRI. HEIGHTS MAY FALL ENOUGH ALONG
THE E COAST BY FRI TO POSSIBLY ALLOW ANY MCS ACTIVITY OVER THE
MIDWEST TO RIDE DOWN THE ERN SIDE OF THE RIDGE TOWARD THE FORECAST
AREA. MAINLY DIURNAL CHC POPS WILL BE FEATURED THU THROUGH
FRI...WITH TEMPERATURES COOLING A COUPLE OF CATEGORIES.

&&

.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
AT KCLT...A DISSIPATING COLD POOL FROM TSTM CLUSTER THAT AFFECTED
THE TERMINAL EARLIER WILL KEEP A N WND AT THE TERMINAL FOR PERHAPS
ANOTHER HOUR OR TWO. THE BEST GUESS FROM THERE ON IS FOR THE WIND TO
REMAIN LIGHT (GENERALLY LESS THAN 5 KTS) AND VEER TO E...THEN S BY
00Z. OTHERWISE...THE MAIN CONCERN WILL BE ADDITIONAL CONVECTION THAT
WILL CONTINUE TO DEVELOP TO THE SW OF THE TERMINAL AND MOVE INTO THE
AREA IN THE 20Z TO 02Z TIME FRAME (PERHAPS HIGH RES MODELS). THO
COVERAGE SHUD BE WIDESPREAD...THE INTENSITY IS EXPECTED TO BE
GENERALLY GARDEN VARIETY TSTMS. WILL KEEP CB AND SHRA MENTION THRU
03Z. FOR THE REST OF THE NIGHT LIGHT WINDS AND MOIST LOW LEVELS WILL
SUPPORT STRATUS DEVELOPMENT. MODEL CONSENSUS IS FOR MVFR CIGS BY
ARND 09Z. THESE CLOUDS WILL SCATTER AND LIFT TO VFR AFTER DAYBREAK
(BY 15-16Z). A FEW SHRA/TSRA MAY DEVELOP AGAIN SATURDAY AFTN...BUT
BE CONFINED MAINLY TO THE NC MTNS.

ELSEWHERE...COVERAGE OF SHRA/TSRA IS INCREASING...SO SHRA/CB MENTION
FOR THE NEXT FEW HOURS. OVERALL INTENSITY OF CONVECTION IS EXPECTED
TO BE MODEST. MVFR CIGS ARE SLOW TO LIFT...BUT ARE STILL EXPECTED TO
REACH VFR WITHIN NEXT 2-3 HOURS AT ALL SITES. THERE IS A CHC THAT
CLOUDS DO NOT SCATTER OUT ENUF...AND THAT MAY RESULT IN MVFR/IFR
CIGS FILLING BACK IN QUICKLY AFTER SUNSET. BUT THE CURRENT MODEL
CONSENSUS IS FOR VFR UNTIL AFTER MIDNIGHT...THEN CIGS LOWER TO MVFR
AND LIKELY IFR IN SPOTS BY DAYBREAK. CLOUDS ARE EXPECTED TO SCATTER
AND LIFT TO VFR AT ALL SITES IN THE 14-16Z TIME FRAME. WINDS WILL BE
LIGHT...BUT LOW CLOUDS SHUD KEEP FOG POTENTIAL TO A MINIMUM (EXCEPT
BEST CHC IN MTN VLYS). KAVL WILL HAVE THE HIGHEST CHC OF SHRA/TSRA
SATURDAY AFTN. FOR NOW...TOO LOW FOR ANY MENTION.

OUTLOOK...A 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.
