AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
453 PM EDT MON JUL 22 2013
.SYNOPSIS...
A BROAD UPPER TROUGH ATOP THE EASTERN UNITED STATES WILL PREVAIL
THROUGH THE REMAINDER OF THE WEEK. A SERIES OF UPPER LEVEL
WAVES...AND A COLD FRONT...WILL PASS THROUGH THE REGION DURING THE
FIRST PART OF THE WEEK KEEPING CHANCES FOR SHOWERS AND THUNDERSTORMS
ELEVATED.
&&
.NEAR TERM /THROUGH TUESDAY/...
AS OF 435 PM EDT...SCT CONVECTION CONTINUES TO FIRE OVER THE FCST
AREA AS WE MOVE INTO THE LATE AFTERNOON. SO FAR...VERY FEW CELLS
HAVE PRODUCED ANY CG LIGHTNING AND THOSE THAT HAVE...SEEM TO FORM IN
SMALL CLUSTERS AND NOT INDIVIDUAL CELLS. I ANTICIPATE THAT
CONVECTIVE ACTIVITY WILL CONTINUE THRU THE EVENING AND TAPER OFF
AFTER MIDNIGHT.
PREVIOUS DISCUSSION...
AT 230 PM EDT... SCATTERED THUNDERSTORMS DEVELOPING OVER HIGHER
TERRAIN IN ADVANCE OF APPROACHING TROUGH ALOFT AND WARMING BOUNDARY
LAYER WILL BE THE MAIN FEATURE OF THE CWA WEATHER DURING THE REST OF
THE AFTERNOON AND THIS EVENING. VERTICAL WIND PROFILES SUGGEST THAT
CELL MOVEMENT TOWARD THE EAST AND NORTHEAST WILL DIMINISH LIKELIHOOD
OF PRECIPITATION REMAINING OVER A LOCATION TOO LONG. HEAVY RAIN WILL
OCCUR... BUT SHOULD BE CONFINED TO SMALL AREAS. NONETHELESS... WILL
HAVE TO MONITOR CONVECTIVE EVOLUTION AND SURFACE FEATURES TO ENSURE
THAT PERSISTENT HEAVY RAINFALL DOES NOT DEVELOP ALONG BOUNDARIES NOT
YET IDENTIFIABLE. CONVECTION ALLOWING MODELS DID A REASONABLY GOOD
JOB OF INDICATING STORMS WOULD DEVELOP AND WE WILL FOLLOW THE TREND
INDICATED BY THE MODELS WHICH SIGNAL CONTINUED WEAKENING OF EASTWARD
MOVING MCS THAT TRAVELED ACROSS TENNESSEE EARLIER IN THE DAY. TROUGH
WILL CROSS THE CWA TONIGHT RESULTING IN CONTINUED POPS FOR
CONVECTIVE STORMS BUT POPS DECREASING LATE TONIGHT AS MOST FAVORABLE
FORCING MOVES INTO FAR EASTERN PART OF CWA. AFTER 12Z TUESDAY... THE
500 MB TROUGH WILL BE EXITING THE AREA FOLLOWED BY ANTICYCLONIC
DIFFERENTIAL VORTICITY ADVECTION FOR MUCH OF THE DAY. THE AIRMASS
WILL BE DRIER ABUT PLAN TO CARRY POPS. NUMBERS WILL BE QUITE A BIT
LOWER THAN THE POPS OF THE PAST SEVERAL DAYS. MOST FAVORABLE
LOCATION FOR AFTERNOON SHOWERS AND THUNDERSTORMS WILL BE OVER THE
MOUNTAINS AND FOOTHILLS. NO MAJOR CHANGES IN TEMPERATURE ARE
EXPECTED. OVERNIGHT LOWS WILL BE IN THE UPPER 60S AND LOWER 70S WITH
LOWER AND MIDDLE 60S IN MOUNTAIN VALLEYS. DAYTIME HIGHS ON MONDAY
WILL BE BETWEEN 85 AND 90 OUTSIDE THE MOUNTAINS AND IN THE LOWER AND
MID 80S IN MOUNTAIN VALLEYS.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
AS OF 130 PM MONDAY...A LONG WAVE TROF AXIS WILL MOVE LITTLE THRU
THE SHORT TERM...EXTENDING SOUTH FROM THE ERN GREAT LAKES THRU THE
CWFA. A SERIES OF SHORTWAVES WILL DIVE SE INTO THE AXIS...AMPLIFYING
THE LONGWAVE AND BRINGING SOME BETTER MID-UPR FLOW AND MID LVL LAPSE
RATES. MEANWHILE...LLVL FLOW WILL REMAIN LARGELY OUT OF THE
WEST...WITH PWATS CLOSER TO SEASONAL NORMS IN THE 100-125% OF NORMAL
RANGE. A WEAK FRONT WILL SAG SOUTH INTO THE AREA BY EARLY
WEDNESDAY...WITH BOTH THE NAM AND GFS AGREEING ON GOOD CONVERGENCE
ALONG THE BNDRY WED AFTN ACRS THE I-85 CORRIDOR. ONE OF THE UPR
SHORTWAVES WILL BE CROSSING THE AREA DURING PEAK HEATING...SO I
EXPECT AT LEAST SOLID CHC POPS FOR THE SRN HALF OF THE CWFA WED
AFTN. A LITTLE MORE FLOW WITH AN AMPLIFYING LONGWAVE SHUD RESULT IN
A LITTLE BIT OF SHEAR AND DECENT STORM MOTIONS. HOWEVER...THE MEAN
FLOW WILL BE NEARLY PARALLEL TO THE BNDRY...SO TRAINING STORMS MAY
BE A THREAT. MAX TEMPS WILL BE NEAR NORMAL.
WEDNESDAY NIGHT AND THURSDAY...A SECOND...MORE POTENT...SHORTWAVE
WILL DIVE INTO THE LONGWAVE TROF...WITH MORE SIGINIFICANT
AMPLIFICATION DEPICTED IN THE GUIDANCE. THERE IS DISAGREEMENT ON THE
EXACT POSITION OF THE TROF AXIS AT THAT POINT...AND ALSO ON WHERE
ANY SFC WAVE/REFLECTION DEVELOPS ALONG A STALLED BNDRY ACRS THE
COASTAL PLAIN. THE 12Z GFS HAS COME IN MORE IN LINE WITH WESTERN AND
WETTER 00Z ECMWF...WHILE THE 12Z NAM IS FURTHER EAST WITH THE
AXIS...AND DRIER FOR THE CWFA. THE 12Z CMC HAS COME IN MUCH FURTHER
WEST...AND IS WETTER FOR THURSDAY AS WELL. SINCE THIS IS MY FIRST
SHIFT IN A FEW DAYS...I HAVE OPTED TO MAKE LITTLE CHANGE TO
THURSDAY/S FCST...WHICH IS FOR A CHC POP ACRS THE AREA. THE GUIDANCE
SHOWS POSSIBLE WEDGE DEVELOPING ON THURSDAY AS WELL...AS A MODEST
SFC HIGH BLDS ACRS THE OH VLY AND NRN MID ATLANTIC...PUSHING SOME
NELY BL FLOW EAST OF THE APPALACHIANS. SO BELOW NORMAL TEMPS ARE
EXPECTED THURSDAY.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 1240 PM EDT MONDAY...WITH WEAK SFC RIDGING IN SUBTLE DAMMING
ORIENTATION ON FRIDAY...WILL LOWER MAX TEMPS A FEW DEGREES FROM THE
GOING FCST. AT THIS POINT...WILL MAINTAIN INHERITED SMALL CHANCE
POP...BUT WITHIN THE DEVELOPING WEAK LLVL UPGLIDE...WE MAY HAVE TO
RAMP POPS UPWARD AS THE WEEK WEARS ON. SOLID CHANCE POP WILL BE
MAINTAINED FOR SATURDAY WITH THE 22/12 UTC OP GFS INCREASING THE
WAA DOWNSTREAM OF FORCING MAXIMA...NOW PROGGED TO ROTATE THRU
THE BASE OF THE L/WV TROUGH. DEEP CONVECTIVE CVRG COULD BECOME
NUMEROUS LATER IN THE WEEKEND WITH A LAYER RH MAXIMA AND FRONTAL
ZONE PROGGED TO SAG SE ACRS THE CWFA SATURDAY NIGHT INTO SUNDAY.
IT REMAINS TO BE SEEN HOW FAR SE SLIGHTLY DRIER POST FRONTAL AIRMASS
WORKS INTO THE SE CONUS BY THE END OF THE PERIOD.
&&
.AVIATION /21Z MONDAY THROUGH SATURDAY/...
AT KCLT... CLOUD BASES WILL INCREASE A BIT MORE DURING AFTERNOON TO
APPROACH THE CCL WHICH IS AROUND 4 KT FT. VISIBILITY UNRESTRICTED
AND SURFACE WIND PRIMARILY SOUTHWEST LESS THAN 10 KT. SCATTERED
THUNDERSTORMS SHOULD BE IN THE VICINITY OF THE AIRFIELD BETWEEN
APPROXIMATELY 21Z AND 00Z WITH REDUCED CEILING AND VISIBILITY AND
GUSTY WIND. AFTER THUNDER THREAT DIMINISHES LATER IN THE EVENING...
RAIN SHOWERS WILL CONTINUE IN THE AREA. OVERNIGHT CLOUD BASES LOWER
TO NR 15 HND FT AND VISIBILITY 3-5 MILES IN FOG. BY 15Z TUESDAY...
BOUNDARY LAYER WARMING AND MIXING WILL CAUSE CLOUD BASES TO LIFT TO
AT OR ABOVE 3K FT AND VISIBILITY UNRESTRICTED.
ELSEWHERE... BOUNDARY LAYER HEATING CONTRIBUTING TO INCREASING CAPE
PROMOTING DEVELOPMENT OF SCATTERED SHOWERS AND THUNDERSTORMS...
ESPECIALLY OVER THE HIGHER TERRAIN. TROUGH ALOFT APPROACHING FROM
THE WEST ALSO CONTRIBUTE TO CONVECTIVE STORM DEVELOPMENT WHICH WILL
CONTINUE INTO THE EVENING. CLOUD BASES OUTSIDE OF SHOWERS WILL BE
3-5K FT AND VISIBILITY UNRESTRICTED. VICINITY SHOWERS AND
THUNDERSTORMS CEILING AND VISIBILITY RESTRICTED IN MODERATE TO HEAVY
RAIN AND FOG. GUSTY WINDS ALSO LIKELY NEAR THUNDERSTORMS. OVERNIGHT
CONVECTIVE STORMS WILL DIMINISH BUT CLOUD BASES WILL LOWER TO AROUND
1K FT AND VISIBILITY 3 TO 5 MILES IN FOG EXCEPT LOCAL VISIBILITY
NEAR 1 MILE KAVL AND KHKY. AFTER 15Z... CLOUD BASES 3 TO 5 KT FT AND
UNRESTRICTED VISIBILITY.
OUTLOOK... SHOWERS AND THUNDERSTORMS WILL ACCOMPANY A COLD FRONTAL
PASSAGE WEDNESDAY BUT BECOME LESS NUMEROUS DURING THE MIDDLE OF THE
WEEK AS HIGH PRESSURE EXTENDS SOUTHWARD FROM THE GREAT LAKES. DURING
THE LATTER PART OF THE WEEK SCATTERED AFTERNOON AND EVENING
THUNDERSTORMS WILL BE MOST NUMEROUS OVER THE MOUNTAINS. MORNING
VISIBILITY RESTRICTIONS DUE TO FOG ARE POSSIBLE EACH DAY.
