Area forecast discussion, Jul 27, 2:29 PM EDT, 23 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
229 PM EDT FRI JUL 27 2012
.SYNOPSIS...
A WEAK COOL FRONT WILL SLOWLY SETTLE SOUTHEAST ACROSS THE REGION
THROUGH THE WEEKEND BEFORE GRADUALLY DISSIPATING. ANOTHER WEAK FRONT
IS EXPECTED TO APPROACH THE REGION BY THE MIDDLE OF NEXT WEEK.
&&
.NEAR TERM /THROUGH SATURDAY/...
AS OF 230 PM...SCATTERED STRONG THUNDERSTORMS HAVE FIRED AS
ANTICIPATED AND EXPECT THEY WILL BECOME NUMEROUS IN THE MID TO
LATE AFTERNOON HOURS ACROSS THE NORTHERN TIER. UPPER VORT MAX
MOVING ACROSS UPSTATE SC AND GENERALLY LOWERING HEIGHTS ALOFT
DRIVING THE CONVECTION. IN REGARD TO THE SEVERE THREAT...THE MID
LEVEL FLOW WILL BE MUCH BETTER TO THE N OF OUR AREA THIS
AFTN...BUT 500 MB WINDS COULD APPROACH 25 KT ACROSS THE FAR NRN
TIER WHICH WOULD SUPPORT A MULTICELL MODE THERE. FARTHER TO THE
SOUTH...THE STRONGLY HEATED BOUNDARY LAYER WILL PRODUCE CAPES OF
1500-2000J WHICH WILL SUPPORT A PULSE SEVERE THREAT PRIMARLY FOR
WET MICROBURSTS.
EXPECT CONVECTION TO WANE QUICKLY AFTER 00Z AS WEAK NVA SETTLES IN
BEHIND THE VORT. HOWEVER...A WEAK AREA OF CONVERGENCE OVER THE
EASTERN UPSTATE MAY ALLOW A COUPLE ISOLATED STORMS TO HANG ON
THERE INTO THE LATE EVENING PER NAM/GFM RESPONSE THAT AREA.
EXPECT GENERALLY A QUIET OVERNIGHT PERIOD WITH DISSIPATING DEBRIS
CLOUDS AND SOME MOUNTAIN VALLEY FOG LATE. A BLEND OF BIAS CORRECTED
MOS INDICATES THAT MIN TEMPS SHOULD BE ABOUT A CATEGORY LOWER THAN
LAST NIGHT...BUT STILL ABOVE AVERAGE.
ON SAT...THE MORNING SHOULD BE GENERALLY QUIET. HOWEVER...DURING THE
AFTERNOON A SECONDARY COLD FRONT WILL CROSS THE AREA FROM NW TO SE.
THIS FRONT WILL BE DRIVEN BY A RATHER IMPRESSIVE SHORT WAVE FOR MID
SUMMER IN THE DEEP SOUTH. HENCE...EXPECT CONVECTIVE DEVELOPMENT
DURING THE MID/LATE AFTERNOON HOURS WITH BEST COVERAGE FROM THE NC
FOOTHILLS ACROSS THE NC PIEDMONT...BUT EXTENDING WEST INTO THE
EASTERN UPSTATE OF SC. SOUNDINGS INDICATE SOME DRY AIR ALOFT SO A
DAMAGING WIND THREAT WILL BE PRESENT AS WELL. MAX TEMPS ON SAT SHOULD
BE ABOUT A CATEGORY LOWER THAN TODAY BASED ON A MOS BLEND. SO NO
HEAT ADVIORY NECESSARY ON SAT ALTHOUGH IT WILL REMAIN HOT AND ABOVE
AVERAGE.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AT 200 PM EDT FRIDAY...AN UPPER TROUGH WILL REMAIN ALONG THE EAST
COAST FROM SATURDAY NIGHT THROUGH MONDAY. A SHORTWAVE WILL EXIT THE
BASE OF THE TROUGH ON SATURDAY NIGHT...AND ANOTHER WILL MOVE INTO
THE THE TROUGH ON SUNDAY. THE REMAINS OF A FRONT WILL BE LOCATED
JUST SOUTHEAST OF OUR AREA ON SUNDAY...AND DEW POINTS SLIGHTLY BELOW
NORMAL ARE EXPECTED. MODEL TIME HEIGHTS SUGGEST A LINGERING MOIST
LAYER BETWEEN 850 AND 700 MB...WITH WEAK UPWARD VERTICAL MOTION
PRESENT. CHANCE POPS WILL BE CARRIED ON SUNDAY... FAVORING THE
MOUNTAINS FOR OROGRAPHIC EFFECTS...AND THE PIEDMONT WHICH WILL BE
CLOSER TO THE FRONT AND BETTER MOISTURE. NAM SOUNDINGS APPEAR
FAVORABLE FOR SEVERE WEATHER...WITH INSTABILITY AND MODEST LOW LEVEL
SHEAR. GFS SOUNDING ARE CHARACTERISTICALLY LESS UNSTABLE....AND ALSO
HAVE LESS SHEAR. TEMPERATURES WILL BE NEAR NORMAL.
ON SUNDAY NIGHT THE SECOND SHORTWAVE ROUNDS THE BASE OF THE
TROUGH... AND ON MONDAY IT EXITS THE AREA. THE OLD SURFACE BOUNDARY
REMAINS JUST OFF TO OUR EAST...AND THE 850 TO 700 MB LAYER REMAINS
MOIST. WITH NO APPARENT UPPER LEVEL FORCING...ONLY VERY SMALL POPS
WILL BE CARRIED IN AN AIR MASS THAT REMAINS UNSTABLE...WITH SURFACE
DEW POINTS RECOVERING TO NEAR NORMAL VALUES.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 1215 PM FRIDAY...MEDIUM RANGE MODELS ARE CONTINUING TO
ADVERTISE THE POTENTIAL FOR ENERGY ROTATING INTO THE REGION ON
TUESDAY WITHIN THE BASE OF LINGERING EASTERN CONUS L/WV TROUGH.
GIVEN THE UNSETTLED LOOK OF THE LARGE SCALE PATTERN...SOLID CHANCE
POP WILL BE NUDGED UPWARD. INTO WEDNESDAY...THERE LOOKS TO BE LITTLE
CHANGE IN THE MEAN PATTERN AND ASSOCIATED SENSIBLE WX...DIURNALLY
ENHANCED TSTM CHANCES. DAILY TEMPERATURES WILL CONTINUE TO BE WITHIN
A FEW DEGREES OF CLIMO. I WOULD EXPECT ABOVE CLIMO TSTM CHANCES TO
CONTINUE INTO THURSDAY AS WELL GIVEN THE ONLY NOMINAL CHANGE TO THE
PATTERN ACRS THE EASTERN CONUS. THE LATEST ECMWF IS HINTING AT A
TRANSITION TOWARD A WEAKER/DEAMPLIFYING FLOW REGIME BY THE END OF
PERIOD. NEW DAY 7 POPS WILL FEATURE SLIGHT AND/OR SMALL DIURNAL
TSTM CHANCES AND TEMPERATURES NEAR PERSISTENCE.
&&
.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
AT KCLT...TIMING OF CONVECTION AT THE AIRPORT IS MAIN PROBLEM.
LATEST LOCAL WRF RUN SEEMS TO BE CAPTURING CONVECTIVE TRENDS AND IT
SUGGESTS THUNDERSTORMS AROUND 20Z FOR THE AIRFIELD. HENCE...WILL RUN
A TEMPO FOR TSRA FROM 20-22Z AND THEN A VCSH TIL AROUND 00Z. EXPECT
AFTER 00Z ONLY SOME CONVECTIVE DEBRIS CLOUDS. IF SUBSTANTIAL RAIN
OCCURS AT THE AIRFIELD...CAN'T RULE OUT SOME MVFR TYPE FOG EARLY ON
SAT...BUT FOR NOW HAVE NOT INTRODUCED THAT. ON SAT...THE MORNING
SHOULD BE QUIET WITH CONVECTION ARRIVING AFTER THIS TAF TIMEFRAME.
ELSEWHERE...SCATTERED TO NUMEROUS THUNDERSTORMS THIS AFTERNOON
ACROSS THE AREA TRIGGERED BY AN UPPER AIR DISTURBANCE.
HENCE...EXPECT ALL AIRFIELDS TO BE AFFECTED IN APPROXIMATELY 19Z-23Z
TIMEFRAME. EXPECT CONVECTION TO WANE QUICKLY AFTER 00Z AS TROUGH
MOVES TO THE EAAT. EXPECT SOME IFR/LIFR MOUNTAIN VALLEY FOG AND
AROUND KHKY AS EXPECT MOST AREAS TO HAVE SOME RAINFALL. CONVECTION
ON SAT SHOULD BE AFTER THIS TAF PERIOD.
OUTLOOK...A DAILY CHANCE OF SCT AFTERNOON CONVECTION WILL THEN
CONTINUE INTO THE MIDDLE OF NEXT WEEK AS AN UPPER TROF REMAINS OVER
THE AREA.
