AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
755 PM EDT TUE JUL 9 2013
.SYNOPSIS...
AN UPPER LEVEL TROUGH OF LOW PRESSURE WILL GRADUALLY DEEPEN OVER THE
EAST THROUGH THE END OF THE WEEK.
&&
.NEAR TERM /THROUGH WEDNESDAY/...
AS OF EARLY EVENING...SCATTERED CLUSTERS OF DEEP CONVECTION CONTINUE
TO FORM ACROSS NE GEORGIA AND THE WESTERN CAROLINAS...AND WILL
CONTINUE TO DO SO AS LONG AS THERE IS SUFFICIENT INSTABILITY. SUPPLY
STILL LOOKS AMPLE AS OF 23Z...WHICH INDICATES THIS SHOULD CONTINUE
WELL INTO THE EVENING. SIMILAR TO LAST NIGHT...THE STORMS WILL BE
SLOW TO MOVE AND SHOULD PRODUCE ISOLATED SIGNIFICANT RAINFALL. NO
BIG CHANGES FOR NOW...BUT WILL TWEAK THE POP AND TEMPS BASED ON
TRENDS ON RADAR.
PREVIOUS DISCUSSION...
AS OF 230 PM EDT TUESDAY...THE ATMOSPHERE OVER THE REGION HAS BECOME
QUITE UNSTABLE THIS AFTN WITH SURFACE BASED CAPE VALUES AVERAGING
AROUND 3000 J/KG ACROSS THE FOOTHILLS AND PIEDMONT. THE LLVL FLOW AS
BACKED AND THERE IS MODEST CONVERGENCE ACROSS THE FOOTHILLS AND NC
BLUE RIDGE. SHOWERS AND TSTMS ARE BEGINNING TO DEVELOP IN THIS AREA.
A COUPLE WEAK NORTHWEST FLOW SHORT WAVE TROUGHS WILL WORK ACROSS THE
REGION INTO THE EVENING.
AS NOT MUCH HAS CHANGED OVER THE PAST 24 HOURS...PERSISTENCE STILL
LOOKS TO BE A GOOD WAY TO GO WITH THIS AFTERNOON/S FORECAST.
SO...MUCH LIKE YDAY...CONVECTION SHOULD INCREASE THROUGH THE AFTN
HOURS AND PEAK SOMETIME DURING THE EVENING. THE WRN UPSTATE...NE GA
AND THE SRN AND CENTRAL NC MTNS SHOULD SEE THE GREATEST COVERAGE AS
THEY ARE UNDER THE BEST DEFINED SHORT WAVE FEATURE THAT I CAN SEE ON
THE WATER VAPOR IMAGERY AND RUC. HOWEVER...WITH HIGH INSTABILITY AND
NO CAP...A STRONG...SLOW MOVING THUNDERSTORM IS POSSIBLE JUST ABOUT
ANYWHERE. WITH WEAKLY DIFFLUENT DEEP LAYER THICKNESSES AND LLVL
WINDS INCREASING A BIT FROM THE SOUTHWEST THIS EVENING CELLS SHOULD
MOVE VERY SLOWLY AND MAY CONSOLIDATE INTO LARGER CLUSTERS LIKE THEY
DID LAST NIGHT. THIS MEANS A FEW AREAS OVER THE REGION ARE LIKELY TO
SEE EXCESSIVE RAINFALL. HOWEVER...OWNING TO THE RATHER ISOLATED
NATURE OF THE HEAVY RAIN THREAT AND DIFFICULTLY NAILING DOWN WHERE
IT WILL HAPPEN...I WILL NOT ISSUE A FLASH FLOOD WATCH FOR THIS
EVENING.
DESPITE WEAK FORCING...INCREASING LAYER RH/S AND A SHARPENING UPPER
TROPOSPHERIC THROUGH SHOULD SUPPORT NUMEROUS SHOWERS AND
THUNDERSTORMS WED AFTN AND EVENING.
&&
.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AT 230 PM EDT TUESDAY...AND UPPER TROUGH WILL AMPLIFY OVER THE
EASTERN USA ON WEDNESDAY NIGHT....PHASING WITH AND EASTERLY WAVE
OVER FL. THE TROUGH AXIS PROGRESSES TO THE EAST COAST ON BY
FRIDAY...DIGGING TO NORTH FL. A BAND OF MOISTURE WILL LINGER OVER
THE WESTERN CAROLINAS AND NE GA ON WEDNESDAY NIGHT....WHILE A COLD
FRONT APPROACHES FROM THE NW. LOW LEVEL FLOW AHEAD OF THE FRONT WILL
BE LIGHT WESTERLY...LIMITING WEAK OROGRAPHIC LIFT TO THE WEST SIDE
OF THE MOUNTAINS. THE FRONT SLOWLY CROSSES OUR AREA ON THURSDAY AND
THURSDAY NIGHT. THE MODELS SHOW DRIER AIR WORKING INTO OUR AREA
BEHIND THE FRONT ON FRIDAY.
ABOVE NORMAL POPS WILL BE CARRIED AHEAD OF THE FRONT IN DEEP
MOISTURE...FAVORING THE TN BORDER AREA. THE GREATEST POPS WILL
FOLLOW THE FRONT EAST OF THE MOUNTAINS ON THURSDAY AND THURSDAY
NIGHT. POPS WILL DECREASE ON FRIDAY IN DRIER AIR...BUT WITH SOME
MOISTURE BANKED UP AGAINST THE BLUE RIDGE...THE GREATEST POPS WILL
BE CARRIED THERE. MAXIMUM TEMPERATURES WILL DECREASE FROM SLIGHTLY
BELOW NORMAL TO ALMOST 10 DEGREE BELOW NORMAL AS HEIGHTS FALL ALOFT.
MINIMUM TEMPERATURES WILL REMAIN NEAR OR SLIGHTLY ABOVE NORMAL IN A
MOIST AIR MASS.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AT 230 PM EST TUESDAY...AN UPPER TROUGH WILL BE ALONG THE EAST COAST
ON FRIDAY NIGHT...AS A NORTHERN STREAM TROUGH REMAINS PHASED WITH
AND EASTERLY WAVE...BETWEEN UPPER RIDGES ON THE WESTERN ATLANTIC AND
THE GREAT PLAINS. THE NORTHERN STREAM TROUGH PROGRESSES INTO EASTERN
CANADA ON SUNDAY...WHILE THE EASTERLY WAVE MOVES WEST ACROSS THE
GULF OF MEXICO. THE UPSTREAM UPPER RIDGE WILL MOVE EAST AND BUILD
OVER THE OH AND TN RIVER VALLEYS ON MONDAY...AND WILL BUILD ACROSS
THE SOUTHERN APPALACHIANS ON TUESDAY.
A STATIONARY FRONT IS EXPECTED TO BE LOCATED FROM THE COASTAL PLAIN
OF THE CAROLINAS TO SOUTH GEORGIA ON SATURDAY...WHILE HIGH PRESSURE
WILL EXTEND FROM SE CANADA TO THE TN RIVER VALLEY. THE FRONT WEAKENS
NEAR THE COAST ON SUNDAY...WHILE HIGH PRESSURE REMAINS OVER THE
APPALACHIANS. THIS HIGH MOVES LITTLE ON MONDAY AND TUESDAY.
THE MODELS SHOW MOISTURE ASSOCIATED WITH THE FRONT LINGERING OVER
OUR AREA IN A LIGHT ISENTROPIC UPGLIDE FLOW OVER THE BOUNDARY. EVEN
WITH THE FRONT DISSIPATING... A LIGHT EASTERLY LOW LEVEL UPSLOPE
FLOW WILL KEEP CLOUDS AND PRECIPITATION OVER OUR AREA INTO EARLY
NEXT WEEK. MAXIMUM TEMPERATURES ARE EXPECTED TO BE BELOW NORMAL
INITIALLY UNDER THE UPPER TROUGH...WARMING TO NEAR NORMAL AS HEIGHTS
RISE WITH THE ARRIVAL OF THE UPPER RIDGE. MINIMUM TEMPERATURES WILL
BE NEAR NORMAL AS LOW LEVEL MOISTURE AND CLOUDS PERSIST.
&&
.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT...VERY UNSTABLE THIS EVENING. SHOWERS WERE FORMING OVER THE
PIEDMONT AND SHOULD CONTINUE TO EXPAND IN AREA AND COVERAGE AS LONG
AS INSTABILITY IS PRESENT...SO HAVE INCLUDED A TEMPO GROUP FOR THE
FIRST TWO HOURS FOR THUNDERSTORMS. CEILING AND VSBY COULD EASILY BE
IFR IF THE CORE OF A STORM MOVES RIGHT OVER THE AIRFIELD...AND WITH
THE SLOW MOVEMENT...IT COULD PERSIST FOR MORE THAN ONE HOUR. THE
STORMS SHOULD BECOME LESS NUMEROUS ONCE THE INSTABILITY IS USED UP
LATER THIS EVENING. AFTER THAT...THE SITUATION IS VERY SIMILAR TO
YESTERDAY...SO PERSISTENCE IS A GOOD FORECAST. THINK WE WILL HAVE AN
EXTENDED PERIOD OF MVFR STRATUS STARTING BEFORE DAYBREAK...WHICH
WILL MORPH INTO A CU FIELD AFTER SUNRISE STARTING WITH BASES IN THE
020-030 RANGE. THIS WILL SCATTER OUT ONCE AGAIN DURING MIDDAY...
FOLLOWED BY MORE SCATTERED STORMS DEVELOPING IN THE AFTERNOON WITH
HEATING. IN GENERAL...WIND WILL BE LIGHT FROM THE S TO SW AWAY FROM
THUNDERSTORMS AND OUTFLOW BOUNDARIES.
ELSEWHERE...STORMS ARE A BIT MORE NUMEROUS APART FROM KHKY...SO WILL
HAVE TO AMEND ACCORDINGLY IF ONE DRIFTS OR FORMS NEAR A TAF SITE.
WITH A PERSISTENT SCENARIO...WHAT HAPPENED LAST NIGHT IS A GOOD
INDICATOR OF THE POTENTIAL FOR MORE OF THE SAME TONIGHT AND
WEDNESDAY MORNING. PLACES THAT HAD RAINFALL IN THE LAST 24 HOURS
WILL BE MORE LIKELY TO HAVE MVFR OR IFR STRATUS/FOG AROUND DAYBREAK.
OUTLOOK...THERE COULD ALSO BE MVFR OR IFR CLOUDS/FOG AROUND DAYBREAK
AND THROUGH MID MORNING ON ANY DAY THROUGH THE WORK WEEK. CHANCES
FOR SHOWERS/STORMS WILL REMAIN HIGH THROUGH FRIDAY. A COLD FRONT
WILL STILL OVER THE REGION THIS WEEKEND...CONTINUING THE CHANCE FOR
THUNDERSTORMS AND MORNING RESTRICTIONS IN LOW CLOUDS.
