AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
534 PM EDT FRI JUL 12 2013
.SYNOPSIS...
ABUNDANT TROPICAL MOISTURE WILL RETURN TO THE AREA THIS
WEEKEND...ALLOWING SHOWERS AND THUNDERSTORMS TO DEVELOP EACH
AFTERNOON. HIGH PRESSURE WILL BUILD IN MONDAY AND PERSIST THROUGH
THE END OF NEXT WEEK.
&&
.NEAR TERM /THROUGH SATURDAY/...
AS OF 5 PM...THE POOL OF BEST SB CAPE VALUES REMAINS ACROSS NE GA
AND THE WESTERN UPSTATE...WHERE OUTFLOW BOUNDARIES ARE CONVERGING TO
INCREASE CONVECTIVE COVERAGE LATE THIS AFTN. WILL DCAPE VALUES
RUNNING 1000 TO 1200...AND A RECENT HISTORY OF QUARTER SIZE HAIL
WITH SOME MID LEVEL DRY AIR...SCATTERED SEVERE TSTMS WILL LIKELY
CONTINUE UNTIL AROUND 8 TO 9 PM. THE SATURATED SOIL CONDITIONS WILL
CONTINUE THE THREAT OF ISOLATED FLASH FLOODING AS WELL. PRECIP
COVERAGE WILL DECREASE LATER THIS EVENING THROUGH THE OVERNIGHT
HOURS. HOWEVER...COPIOUS LOW LEVEL MOISTURE AND UPSLOPE FLOW WILL
LEAD TO INCREASING CLOUDINESS AND ISOLATED OR POSSIBLY SCT LIGHT
SHRA.
THE UPPER LOW RETROGRADES TO THE MS VALLEY SAT...WHILE AT THE SFC AN
INVERTED TROF MOVES INTO THE AREA FROM THE COAST. THIS WILL KEEP LOW
LEVEL SELY UPSLOPE FLOW ACROSS THE AREA THRU THE DAY WITH CONTINUED
COPIOUS LOW LEVEL MOISTURE. THE NAM IS ALONE IN KEEPING DEEP
MOISTURE OUT OF THE AREA WITH THIS SYSTEM...SO HAVE FOLLOWED THE
TRENDS OF THE OTHER GUIDANCE AND INCREASE POP TO LIKELY OUTSIDE OF
THE MTNS BY AFTERNOON. THERE WILL BE ENUF INSTABILITY FOR
THUNDERSTORMS TO DEVELOP...BUT SEVERE WILL BE LESS LIKELY AS THE
COOL AND DRY MID LEVELS MOVE WEST WITH THE UPPER LOW. FOR NOW...THE
QPF FORECAST DOES NOT SUGGEST WIDESPREAD FLOOD POTENTIAL DURING THE
DAY SAT. THEREFORE...WILL NOT ISSUE A WATCH ATTM...BUT LATER SHIFTS
WILL NEED TO EVALUATE THE POTENTIAL.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF MIDDAY FRI...ATLANTIC MOISTURE WILL HAVE SPREAD ACROSS THE CWFA
BY THE START OF THE PERIOD IN THE WAKE OF WARM FRONT. MODEST E TO SE
LLVL FLOW WILL BE UNDERWAY AT THAT TIME AND CONTINUE THROUGH THE END
OF THE PERIOD. THIS UPSLOPE FLOW WILL PROVIDE AT LEAST WEAK FORCING
WITH THE MAIN EFFECT TO ENHANCE THE COVERAGE OF ALREADY DIURNALLY
DRIVEN CONVECTION.
THE INITIAL WAVE OF MOISTURE AS SHOWN BY A PLUME OF PWATS NEAR 2
INCHES CROSSES THE CWFA SATURDAY NIGHT INTO SUNDAY MORNING...BUT
DIMINISHES SOMEWHAT AS THE PLUME MOVES INLAND. SATURATED LAYER ON
PROG SOUNDINGS REMAINS SOMEWHAT SHALLOW WITH BEST LOOKING SOUNDINGS
IN THIS REGARD COMING FROM THE MTNS/FOOTHILLS. WEAK NEAR-SFC
INSTABILITY IS SEEN THOUGH...AND INDEED THE NAM PRECIP SHOWN SAT
NIGHT IS ALL CONVECTIVE. CLOUD LAYER FLOW LOOKS STRONG ENOUGH AT THIS
TIME TO LIMIT...BUT NOT TOTALLY ELIMINATE...THE FLASH FLOOD THREAT.
GOING FURTHER INTO THE DAY ON SUNDAY SOME DRYING OCCURS AND PWATS
LOWER CLOSER TO CLIMO. DESPITE THE RELATIVE LACK OF MOISTURE...CAPE
VALUES OF 2000 J OR MORE ARE SHOWN ON THE NAM /1000 OR MORE ON GFS/
SO SOME VIGOROUS CONVECTION COULD DEVELOP. SHEAR WILL CONTINUE TO BE
WEAK BUT STORM MOTIONS FAIRLY SLOW...THUS MORE OF THE SAME CONCERNS
IN THAT REGARD BUT PERHAPS WITH MORE CONCERN FOR SVR WX.
HIGH PRESSURE BUILDS IN SUN NIGHT SOMEWHAT DISRUPTING THE LLVL FLOW
ON THE GFS/NAM DEPICTION OF THE FEATURE...AND CONTINUING TO DRY THE
ATMOSPHERE. A WEAK MIDLEVEL SUBSIDENCE INVERSION DEVELOPS BUT SOME
PROG SOUNDINGS STILL SHOW VERY WEAK INSTABILITY DESPITE A REFLECTION
OF THE SUBSIDENCE. THUS HUNG ON TO VERY LOW BUT MENTIONABLE POPS THRU
THE NIGHT...SLIGHTLY HIGHER WEST WHERE THE BEST LLVL MOISTURE
REMAINS. ON MONDAY WARM MIDLEVELS APPEAR TO CONTINUE TO STIFLE
CONVECTION PARTICULARLY TOWARD THE NORTH NEARER THE CENTER OF THE
HIGH.
WITH THE REGION COMING BACK INTO A MORE TYPICAL PATTERN DOMINATED BY
ATLANTIC HIGH PRESSURE...TEMPERATURES SHOULD MODERATE TO NEAR NORMAL
DURING THE PERIOD...REMAINING SLIGHTLY BELOW NORMAL GIVEN THE MORE
NORTHWARD THAN USUAL POSITION OF THE HIGH.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 130 PM FRIDAY...THE OVERALL PATTERN HAS BECOME DRIER IN THE
LATEST OP MODEL RUNS. THE 12Z GFS IS STILL A MOISTER MODEL WITH THE
UPSLOPE FLOW...WHILE THE ECWMF KEEPS LLVL LAYERED RH THE RATHER LOW.
IN ANY CASE...A DEEP SUB INVERSION WILL BE IN PLACE THROUGH MOST OF
THE PERIOD ASSOCIATED WITH THE ANOMALOUS STACKED HIGH. THUS...SCF
BASED PARCELS WILL HAVE A GOOD AMOUNT OF CIN TO OVERCOME WITH NO
DEFINED KICKER...HOWEVER SOME MODERATE ELCAPE WILL BE AVAILABLE AND
AREAS UNDER DIFFERENTIAL HEATING SHOULD SPAWN ISOL AFTERNOON PULSE
STORMS. THE CLIMO POP IS ADHERED TO ACROSS THE MTNS AS WELL...WITH
NE/LY TO E/LY MECH LIFT PROVIDING THE ADDED FACTOR FOR SCT AFTERNOON
CONVECTION. PWATS WILL REMAIN RELATIVELY LOW...YET INCREASE AS THE
PERIOD PROGRESSES IN A MORE DEFINED AND CONTINUOUS SW/LY LLVL FLOW
ASSOCIATED WITH A DEVELOPING AND NORMALLY PLACED BERMUDA HIGH. MAX
TEMPS WILL RESPOND IN THE DRIER ENVIRONMENT AND A RETURN TO NEAR
NORMAL LEVELS IS EXPECTED THROUGH THE PERIOD. NORMAL MIN TEMPS WILL
ALSO PERSIST AS EVENING CONVECTIVE CLOUDS DISSIPATE AND ALLOW GOOD
RADIATIONAL COOL CONDS.
&&
.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
AT KCLT...THE VICINITY HAS BEEN LARGELY EXEMPT FROM CONVECTION THIS
AFTERNOON...WITH OUTFLOW BOUNDARIES MAINLY S AND W OF THE AREA
MOVING AWAY INTO SC. WILL JUST MENTION VCSH FOR A POSSIBLE ROGUE
SHOWER...WITH VFR CIGS THROUGH THE LATE EVENING HOURS. LOW END GUSTS
ARE LIKELY THROUGH AT LEAST SUNDOWN. ANTICIPATE A RETURN TO MVFR AND
THEN IFR STRATUS OVERNIGHT WITH CONTINUED HIGH LEVELS OF BOUNDARY
LAYER MOISTURE. THERE SHOULD BE A SLOW RISE TO MVFR THROUGH THE
MORNING HOURS ON SATURDAY. NE WINDS CONTINUE THROUGH THE PERIOD WITH
OCCASIONAL GUSTS...AND SHRA/TSRA POSSIBLY REDEVELOPING NEAR THE END
OF THE PERIOD.
ELSEWHERE...KAVL AND THE UPSTATE TAFS WILL SEE ADDITIONAL
THUNDERSTORMS DEVELOPING ON OUTFLOWS THROUGH THE EARLY EVENING
HOURS...WITH DRYING AT KHKY. ANTICIPATE COVERAGE DIMINISHING
OVERNIGHT...BUT WITH ROGUE -SHRA POSSIBLE IN ANY UPSLOPE MOISTURE.
ANTICIPATE MAINLY IFR CIGS THROUGH DAYBREAK...IMPROVING THROUGH MVFR
INTO EARLY AFTERNOON...WITH SHRA/TSRA REDEVELOPING SAT AFTN. EXPECT
MAINLY NE WINDS AWAY FROM ANY TSTMS...WITH BRIEF GUSTS THIS
EVENING.
OUTLOOK...A COLD FRONT WILL SLOWLY DISSIPATE THROUGH THE WEEKEND.
LOW LEVEL MOISTURE WILL PERSIST...CONTINUING THE CHANCES FOR DIURNAL
THUNDERSTORMS AND MORNING FOG/LOW CLOUDS INTO EARLY NEXT WEEK.
