AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1039 AM EDT FRI JUN 19 2015
.SYNOPSIS...
THE REMNANT CIRCULATION OF TROPICAL SYSTEM BILL WILL MOVE UP THE
OHIO VALLEY TODAY THROUGH SATURDAY...WITH ASSOCIATED MOISTURE LIKELY
BRUSHING WESTERN NORTH CAROLINA SATURDAY NIGHT. A SLIGHT BREAK IN
THE HEAT IS EXPECTED THROUGH THE WEEKEND...BUT WITH TEMPERATURES
STILL ABOVE NORMAL. A RIDGE OF HIGH PRESSURE WILL THEN GRADUALLY GET
REESTABLISHED THROUGH NEXT WEEK...WITH A STATIONARY FRONT DEVELOPING
JUST NORTH OF THE AREA. VERY HOT CONDITIONS WILL RETURN AND PERSIST
NEXT WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
AS OF 1035 AM EDT FRIDAY...EARLIER LOW FOG/STRATUS IN AND AROUND THE
MOUNTAINS VALLEYS HAS ERODED AS THE BL HEATS AMONGST ABUNDANT
INSOLATION. MOST RECENT VISB SAT IMAGERY INDICATES CU FIELD ALREADY
EXPANDING ACROSS THE MOUNTAINS WHERE SPC MESO PLOTS SHOW SBCAPE
VALUES ALREADY APPROACHING 1K J/KG. LIKEWISE...LATEST GUIDANCE
CONTINUES TO KEY ON LATE MORNING CONVECTIVE INITIATION ACROSS THE
BLUE RIDGE WHERE UPPER HEIGHT FALLS ARE MOST PREVALENT. THUS OPTED
TO INCREASE POPS TO LIKELY LEVELS OVER MUCH OF THE HIGH TERRAIN BY
LATE MORNING...THEN SPREADING EAST OVER THE REMAINDER OF THE I40
CORRIDOR OF WESTERN NC BY AFTERNOON/EVENING AS A WEAK CONVERGENCE
AXIS IS PROGGED BY GUIDANCE. THIS BOUNDARY IS FAVORED IN MOST
GUIDANCE SOURCES HOWEVER WITH SOME PLACEMENT DISCONTINUITY. WITH
THAT IN MIND...KEPT POPS AS THEY WHERE AT SOLID CHANCE LEVELS FOR
THE LOWER NC PIEDMONT...MOST OF NORTHEAST GA...AND UPSTATE SC.
OTHERWISE...THE CURRENT FCST REMAINS ON TRACK AND NO OTHER SIG
CHANGES WERE MADE/NEEDED WITH THIS UPDATE.
PREVIOUS DISCUSSION...
MAX TEMPS AND HI VALUES WILL AGAIN BE THE MAIN ISSUE FOR THIS
AFTERNOON. HOWEVER..UPPER LEVEL HEIGHTS DROP ACROSS THE NRN ZONES AS
THE H5 RIDGE FLATTENS WHILE LLVL THICKNESSES LOWER AS WELL. MAX
TEMPS WILL BE LOWER THAN RECENT LEVELS...ESP ACROSS THE I-40
CORRIDOR. WITH TD/S MIXING OUT THIS AFTERNOON...HI LEVELS OVER THE
NRN ZONES WILL BE CLOSE TO AMBIENT TEMPS...WHILE THE HI AROUND AND
SOUTH OF I-85 WILL REACH THE U90S TO ARND 100 F. SO...WILL MAINTAIN
HIGH HI MENTION IN THE HWO THIS AFTERNOON. AFTERNOON CONVECTION
SHOULD HAVE NO PROBLEM INITIATING ACROSS THE NRN ZONES WHERE
DAYTIME HEATING AND THE LOSS OF A MLVL CAP ALLOW MODERATE SBCAPE
VALUES IN A MOIST ENVIRONMENT. STORMS SHOULD BECOME NUMEROUS ACROSS
THE MTNS/FTHILLS...THEN ISOL/SCT ALONG NE GA AND THE SC/NC PIEDMONT.
PULSE SEVERE WILL BE THE MODE...WITH MORE OF A WIND THREAT DUE TO
PRECIP LOADING AND HIGH SFC-BASED LAPSE RATES.
OVERNIGHT...CONVECTION WILL AGAIN WANE QUICKLY AFTER SUNSET WITH
ISOL LINGERING ACTIVITY TIL MIDNIGHT MAINLY OVER THE SRN ZONES DUE
TO A SFC HIGH PUSHING INTO THE NC FOOTHILLS/PIEDMONT. INCREASING
AMOUNTS OF MOISTURE WILL ADV INTO THE SW MTNS AHEAD OF THE REMNANTS
OF TS BILL WHICH COULD KEEP -SHRA/TSTMS ACTIVE THROUGH DAYBREAK. MIN
TEMPS WILL BE A LITTLE LOWER...YET STILL ABOUT 5 DEGREES ABV NORMAL.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 245 AM EDT FRIDAY...EXPECT ANOTHER ROUND OF AT LEAST MID 90S
TEMPS ACROSS THE CHARLOTTE METRO AREA ON SATURDAY...BUT WITH
SLIGHTLY COOLER TEMPS WEST IN GREATER CLOUDINESS. THE TROUGH
ASSOCIATED WITH THE REMNANTS OF TROPICAL SYSTEM BILL WILL CROSS THE
SRN/CENTRAL APPALACHIANS MAINLY DURING THE LATE SAT/SAT NIGHT TIME
FRAME. THE BEST DEEP LAYER DPVA WILL PASS N OF THE REGION THROUGH
THE VIRGINIAS...BUT IMPROVING S TO SW FLOW SHOULD YIELD AT LEAST
NUMEROUS SHOWER/TSTM COVERAGE ACROSS THE NRN/WRN MTNS AND POSSIBLY
THE NRN TIER OF WRN NC THROUGH SAT NIGHT. ALTHOUGH SHEAR PROFILES
INCREASE...BULK SHEAR VALUES WILL NOT BE TERRIBLY IMPRESSIVE AND
THERE SHOULD BE LITTLE BACKING OF THE LOW LEVEL FLOW. IN
ADDITION...THE MAINLY NIGHTTIME PASSAGE WILL KEEP SURFACE BASED
INSTABILITY SOMEWHAT LIMITED TO CURTAIL THE SEVERE TSTM THREAT. THE
NRN MTNS COULD SEE THE HEAVIEST RAINFALL...BUT THE RELATIVELY SHORT
LIVED NATURE OF THE HEAVIER PRECIP SHOULD CURTAIL ANY SIGNIFICANT
HYDRO ISSUES.
NW UPSLOPE FLOW MOISTURE MAY CONTINUE TO PRODUCE SHOWERS ALONG THE
SPINE OF THE MTNS INTO SUNDAY MORNING...BUT A DRYING NW FLOW IS
EXPECTED EAST OF THE HIGH TERRAIN THROUGH LATE WEEKEND. ALTHOUGH
THERE ARE VARYING DEGREES OF MODEL INSTABILITY ACROSS THE AREA
SUNDAY AFTN...THE GFS PROFILES HAVE A STRONGER CAPPING INVERSION
ALOFT. WILL THUS HOLD COVERAGE AT CHC WESTERN MTNS AND SLIGHT CHANCE
SE SECTIONS THROUGH LATE WEEKEND. MAX TEMPS WILL START TO RISE AGAIN
BY LAKE WEEKEND BEHIND THE DEPARTING WAVE...WITH PLENTY OF MID 90S
EAST OF THE MTNS.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
AS OF 255 AM EDT FRIDAY...THE HEAT SHOULD RETURN IN EARNEST NEXT
WEEK. A BROAD WRN RIDGE AND ERN TROUGH PATTERN WILL DEVELOP THROUGH
EARLY NEXT WEEK. CONTINUED HIGH LOW LEVEL THETA E VALUES MAY PERMIT
SB CAPE TO REACH 2000 TO 3000 J/KG ACROSS THE REGION MON AFTN...BUT
WARM CAPPING TEMPS ALOFT MAY CONTINUE TO CURTAIL CONVECTION. THE
UPPER LEVEL RIDGE WILL THEN BECOME RESURGENT FROM THE W TUE THROUGH
THU...WHILE A STATIONARY FRONT WILL SET UP JUST NORTH OF THE AREA
THROUGH NEXT WEEK. THERE IS NOW LITTLE INDICATION OF MUCH
BACKDOORING OF THE FRONTAL ZONE...SO UPPER 90S TO NEAR 100 TEMPS
WILL BECOME COMMON EAST OF THE MTNS TUE TO THU...WITH LOWER 90S IN
THE MTN VALLEYS. THERE IS SOME POTENTIAL FOR UPSTREAM CONVECTIVE
ACTIVITY TO SLIDE SOUTHEAST ALONG THE STALLED FRONTAL ZONE AND
APPROACH THE FORECAST AREA...WHICH COULD LEAD TO BETTER THAN CLIMO
COVERAGE AND PERHAPS SOME INCREASE SKY COVER TO CAP TEMPS.
HOWEVER...MAINLY DIURNAL ISOLATED TO SCATTERED CONVECTION SEEMS A
BETTER BET.
&&
.AVIATION /15Z FRIDAY THROUGH TUESDAY/...
AT KCLT...OUTSIDE OF POSSIBLE AFTERNOON TSTMS WITHIN 5
MILES...WINDS...VBSY AND CIGS SHOULD BE GOOD THROUGH THE TAF PERIOD.
LIGHT WINDS WILL BEGIN SW/LY THEN ADJ OUT OF THE NNW AS A HIGH
CENTER GETS PUSHED NE BY THE REMNANTS OF TS BILL AND A LEE TROF
DEEPENS. LIGHT NE WINDS AFT CONVEC AS TROF WEAKENS AND HIGH CENTER
MOVES INTO WRN NC.
ELSEWHERE...TEMPORARY MORNING LIFR CIGS POSSIBLE THRU 13Z AT KAVL AND
KGMU. ALL SITES WILL BECOME VFR AFT 13Z WITH HEATING INITIATING
QUICKLY. WINDS WILL REMAIN LIGHT OUTSIDE OF POSSIBLE TSTMS GUSTS AND
GENERALLY ALIGN NW/LY TO SW/LY...THEN NE/LY NON/MTNS AS HIGH CENTER
BUILDS SOUTH LATE THIS EVENING.
OUTLOOK...AFTN CONVECTION IS EXPECTED INTO SATURDAY...WITH A
DECREASE AT KCLT AND THE SC SITES EARLY NEXT WEEK. MORNING
RESTRICTIONS DUE TO FOG AND/OR STRATUS ARE POSSIBLE...PARTICULARLY
WHERE HEAVY RAIN FELL THE PREVIOUS DAY...AND IN MTN VALLEYS.
