NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at May 27, 1:48 PM EST, 1 hour 39 minutes earlier.
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. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...NONE. NC...NONE.
