AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
758 PM EDT MON MAY 18 2015

.SYNOPSIS...
BERMUDA HIGH PRESSURE WILL WEAKEN OVER THE REGION TONIGHT AND
TOMORROW. A COLD FRONT WILL GRADUALLY APPROACH AND MOVE OVER THE
AREA LATE MONDAY THROUGH TUESDAY NIGHT...BRINGING INCREASED
PRECIPITATION CHANCES TO THE REGION. SLIGHTLY COOLER AND DRIER HIGH
PRESSURE WILL RETURN ON WEDNESDAY...WITH SOMEWHAT UNSETTLED WEATHER
LINGERING THROUGH THURSDAY. ANOTHER ROUND OF DRIER HIGH PRESSURE
WILL RETURN TO OUR NORTH ON FRIDAY.

&&

.NEAR TERM /THROUGH TUESDAY/...
AS OF 540 PM...UPDATED THE POPS AGAIN...BUMPING THEM UP TO
LIKELY/CAT ACROSS THE UPSTATE TO LINE UP WITH RADAR TRENDS.
CONVECTION WILL BEGIN TO SUBSIDE QUICKLY ONCE THE SUN SETS.

AS OF 415 PM...UPDATED THE POPS FOR THE REST OF THIS AFTN THRU THIS
EVENING TO REFLECT LATEST RADAR TRENDS AND CONVECTION-ALLOWING
MODELS. EXPECT NUMEROUS SHWRS AND A FEW EMBEDDED TSTMS TO CONTINUE
ACRS THE REGION...WITH THE HIGHEST COVERAGE BEGINNING TO SHIFT FROM
THE MTNS TO THE PIEDMONT. OTHERWISE...TEMPS/WINDS/SKY ALL LOOK ON
TRACK.

PREVIOUS DISCUSSION...
WITHIN THE PLUME OF ABOVE CLIMO PWAT VALUES AND LESSENING
INHIBITION/UPPER LEVEL HEIGHT FALLS ATOP THE SE CONUS...NUMEROUS
SHOWERS AND TSTMS WILL CONTINUE TO PERCOLATE ACRS THE MOUNTAINS AND
BECOME MORE NUMEROUS IN THE PIEDMONT. FORCING AND INSTABILITY SHOULD
REMAIN ON THE WEAK SIDE THIS AFTERNOON...SBCAPE VALUES TOPPING OUT
JUST SHY OF 1500 J/KG. THE MAIN THREAT FOR STORMS TODAY WILL BE
THE POTENTIAL TO PRODUCE A PERIOD OF HEAVY RAIN...BUT WITH A 10-15
KT STORM MOTION...ANY EXCESSIVE RAINFALL CHANCES ARE LIMITED.

DIURNAL LESSENING OF DEEP CONVECTIVE CVRG AND INTENSITY IS EXPECTED
THIS EVENING...BUT THERE REMAINS A SMALL POSSIBILITY OF SOME OUTFLOW
BOUNDARIES SLIPPING IN FROM THE WEST TONIGHT IN COMBINATION WITH THE
NWLY UPSLOPE FLOW. THIS WARRANTS MAINTENANCE OF CHC POPS ALONG
THE TENN BORDER OVERNIGHT. MIN TEMPS WILL BE 7-10 DEGREES ABOVE
NORMAL UNDER MOSTLY CLOUDY SKIES.

ON TUESDAY...ENCROACHING SFC COLD FRONT IS PROGGED JUMP TO
LEE/PIEDMONT TROUGH AND THE ONSET OF A MORE CONTINENTAL AIRMASS
WILL DISPLACE HIGH PWAT PLUME DOWNSTREAM OF THE CWFA BY EVENING.
DESPITE SOME WEAK DOWNSLOPE FLOW INITIALLY WEST OF THE SFC
TROUGH...ENUF LLVL CONVERGENCE SHOULD BE REALIZED WITH THE SEWARD
MOVEMENT OF SFC FRONT...AIDING IN DIURNALLY ENHANCED TSTMS. AT THIS
POINT...THE SHOTGUN CHANCE POP WILL REMAIN WITH PIEDMONT MAXIMUMS
CLOSE TO PERSISTENCE.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
AS OF 135 PM MONDAY...DRIER AIR ASSOCIATED WITH CP HIGH PRESSURE
WILL BEGIN PUSHING INTO THE REGION TUE NIGHT...WHICH SHOULD LEAD TO
QUICK DISSIPATION OF ANY LINGERING DIURNAL CONVECTION. THIS WILL
ALSO RESULT IN MINIMAL INSTABILITY ACROSS THE FORECAST AREA WED
AFTERNOON...EXCEPT PERHAPS ACROSS FAR SOUTHERN AREAS...WHERE SOME
ISOLATED LATE DAY CONVECTION CANNOT BE RULED OUT. ALSO CANNOT
COMPLETELY RULE OUT SOME SHOWERS DEVELOPING OVER THE SOUTHERN
MTNS...BUT COVERAGE WOULD BE ISOLATED AT BEST.

BY LATE WED NIGHT/EARLY THURSDAY...SHORT TERM NUMERICAL GUIDANCE IS
IN GOOD AGREEMENT IN DIGGING A SHORT WAVE TROUGH AS FAR SOUTH OF THE
OHIO VALLEY...WITH HEIGHT ASSOCIATED HEIGHT FALLS SENDING A
REINFORCING SURFACE BOUNDARY TOWARD THE AREA THURSDAY. WHILE THE
MODELS DO AGREE ON THIS SCENARIO...THE NAM IS DECIDEDLY MORE POTENT
WITH THE WAVE THAN OTHER MODELS...AND ALSO CONSIDERABLY MORE MOIST
AND UNSTABLE ACROSS THE FORECAST AREA THU AFTERNOON...WITH FAIRLY
WIDESPREAD SBCAPE VALUES IN THE 1000-2000 J/KG RANGE. MEANWHILE...
THE LATEST SREF MUCAPE PROBABILITIES LEND LITTLE SUPPORT TO THE
NAM/S MORE ROBUST BUOYANCY...AND SO WILL LIMIT POPS TO 20-30 PERCENT
THU AFTERNOON. DESPITE THE INTRODUCTION OF A CP AIR MASS...THE MAIN
EFFECT WILL ESSENTIALLY BE LOWER RH...AS THICKNESS VALUES WILL STILL
SUPPORT TEMPS ABOVE CLIMO THROUGH THE PERIOD.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 155 PM EDT MONDAY...THE MEDIUM RANGE FCST BEGINS AT 00Z ON
FRIDAY WITH A BROAD UPPER TROF DIGGING DOWN OVER EXTREME SE CANADA
AND NEW ENGLAND. HEIGHTS ARE NOT EXPECTED TO FALL MUCH OVER THE SE
REGION AS THE TROF DOES NOT DEEPEN ENOUGH OVER OUR AREA. HEIGHTS
BEGIN TO RISE AGAIN ON SAT AS UPPER RIDGING FROM THE WEST SPREADS
OVER THE REGION AND REMAINS IN PLACE THRU EARLY NEXT WEEK.

AT THE SFC...ANOTHER CANADIAN HIGH WILL WILL MAKE ITS WAY SOUTHWARD
FROM CANADA ON FRI AND SETTLE TO OUR NORTH BY EARLY SAT. THIS WILL
CAUSE LOW LVL FLOW TO BECOME MORE NLY AND THEN NELY BY SAT MORNING.
AS WE MOVE INTO SUN...THE CENTER OF THE HIGH BEGINS TO MOVE OFF THE
EAST COAST AND THE FLOW VEERS AROUND TO MORE SELY WITH MORE MOIST
PROFILES EXPECTED...ESPECIALLY OVER THE UPSLOPE AREAS. THIS PATTERN
WILL PERSIST THRU THE REMAINDER OF THE MEDIUM RANGE WITH A
WEAK/DIFFUSE FRONT...ASSOCIATED WITH A NORTHERN PLAINS
LOW...APPROACHING THE CAROLINAS BY THE VERY END OF THE PERIOD LATE
MONDAY.

AS FOR THE SENSIBLE FCST...POPS TAPER OFF QUICKLY ON FRI MORNING AS
THE SFC HIGH MOVES FARTHER SE AND PROFILES DRY. THE REST OF FRI AND
SAT SHOULD BE MOSTLY DRY WITH POPS INCREASING ON SUN AND MON AS MORE
MOIST...SELY FLOW SPREADS BACK OVER THE REGION. TEMPS WILL COOL ON
FRI AND SAT BUT LIKELY REMAIN ABOVE CLIMATOLOGY...AND THEN WARM
AGAIN ON SUN AND MON AS HEIGHTS RISE AND SLY FLOW SPREADS BACK OVER
THE REGION.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
AT KCLT...SCATTERED CONVECTION CONTINUES TO BUBBLE UP AROUND THE
KCLT TERMINAL. WILL TEMPO IN A COUPLE HOURS OF POTENT TSRA IMPACT.
AFTER 02Z...EXPECT CONVECTION COVERAGE TO DIMINISH...WITH LINGERING
VFR LVL MID AND HIGH CLOUDS OVERNIGHT. IF KCLT GETS A HEAVY
DOWNPOUR...CANNOT RULE OUT SOME PATCHY FOG AROUND THE TERMINAL
BEFORE DAWN ON TUESDAY. FOR NOW...WILL KEEP KCLT VFR OUTSIDE ANY
TSRA. A VERY WEAK FRONT WILL PUSH THRU THE AREA TUESDAY
MORNING...SHIFTING THE WIND TO NW. NOT EXPECTING AS MUCH
CONVECTION...BUT STILL THINK A PROB30 FOR TS IS WARRANTED. ANY
ACTIVITY THAT DEVELOPS WILL SHIFT EAST OF THE AREA EARLY...AS DRY
AIR FILTERS IN FROM THE NW BY MID AFTN.

ELSEWHERE...ALL THE TERMINALS HAVE GOTTEN SOME HEAVY DOWNPOURS THIS
AFTN...WITH WET GROUND AND LIGHT WINDS OVERNIGHT. WILL PROBABLY SEE
SOME PATCHY FOG AROUND. I WILL GO WITH JUST MVFR VSBY FOR NOW DURING
THE PRE-DAWN HOURS. THERE IS ANOTHER AROUND OF TSTMS ENTERING
WESTERN NC/SC THIS EVENING...BUT WILL WEAKEN AS IT APPROACHES KAVL
AND THE UPSTATE TERMINALS. I WILL KEEP A VCTS AT KAVL FOR THE NEXT
COUPLE HOURS...AS KAVL HAS THE BEST CHC OF MORE TSTMS AROUND BEFORE
LOSS OF DAYTIME HEATING KILLS THE CONVECTION. OTHERWISE...EXPECT A
MIX OF LOW TO HIGH CLOUDS (MAINLY CONVECTIVE DEBRIS)...WHICH WILL
HELP LIMIT MORE WIDESPREAD FOG. KAVL MAY SEE MVFR CIGS WITH THE
CLOUD COVER...AS WINDS SHIFT TO NW UP THE VALLEY. ON TUESDAY...AS
WITH KCLT...EXPECT ISOLD TO SCATTERED CONVECTION ASSOCIATED WITH A
PASSING WEAK COLD FRONT. CONVECTION WILL HAVE AN EARLIER THAN CLIMO
START...AND PUSH OFF TO THE EAST BY MID-LATE AFTN...AS DRY AIR
FILTERS IN FROM THE WEST. WINDS WILL FAVOR A NW DIRECTION ON TUESDAY.

OUTLOOK...THE PASSAGE OF A WEAK COLD FRONT SHOULD BRING BACK
SOMEWHAT DRIER CONDITIONS FOR WEDNESDAY. ANOTHER FRONT WILL CROSS
THE AREA THURSDAY...WITH A LITTLE MORE COVERAGE OF MAINLY AFTN SHRA
AND TSRA. DRY WX RETURNS FOR THE UPCOMING WEEKEND.
