Area forecast discussion, Jun 7, 9:52 PM EDT, 1 hour 21 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
952 PM EDT FRI JUN 7 2013

.SYNOPSIS...
THE REMNANT LOW OF TROPICAL STORM ANDREA WILL MOVE NORTHEAST OF THE
CAROLINAS TONIGHT WHILE A WEAK COLD FRONT CROSSES THE CAROLINA
PIEDMONT. WEAK HIGH PRESSURE WILL SETTLE BACK IN OVER THE WEEKEND
WITH ANOTHER WEAK COLD FRONT EXPECTED TO ARRIVE EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH SATURDAY/...
AS OF 950 PM EDT...SURFACE ANALYSIS PLACES THE CENTER OF NOW POST
TROPICAL STORM ANDREA AROUND THE VICINITY OF NORFOLK VIRGINIA.
FURTHERMORE...SATELLITE WV IMAGERY INDICATES A POSITIVELY TILTED
TROF AXIS ALONG THE MISSISSIPPI RIVER VALLEY.  AS THE TROF CONTINUES
ITS GRADUAL PUSH TO THE EAST...A WEAK SHORT WAVE WILL ROUND THE BASE
THIS EVENING GIVING JUST ENOUGH UPPER LEVEL SUPPORT FOR PROLONGED
SHOWER ACTIVITY ACROSS THE CWFA.  CURRENTLY...CONVECTION CONTINUES
ACROSS THE REGION WITH THE HEAVIEST CROSSING THE GEORGIA STATE LINE
INTO THE MIDLANDS OF SC.  LOCALLY...SHOWER ACTIVITY CONTINUES AND
WILL REMAIN A POSSIBILITY THROUGH THE EVENING.  KEPT LIKELY POPS
EARLY ON BEFORE GIVING WAY TO SOLID CHANCE POPS BY MORNING ACROSS
THE NORTH AND SLIGHT CHANCE POPS ACROSS THE UPSTATE.  SKY COVER
SHOULD REMAIN FAIRLY SOLID THROUGH THE OVERNIGHT HOURS LEADING TO
ABOVE NORMAL LOW TEMPERATURES.  AS SOUTHERLY FLOW CONTINUES DURING
THE DAY TOMORROW...BROKEN SKY COVER WILL ALLOW FOR MODEST HEATING
LEADING TO NEAR NORMAL HIGHS.  ALTHOUGH SYNOPTIC FEATURES WILL NOT
BE SIGNIFICANT...THERE WILL BE A CHANCE FOR SCATTERED AFTERNOON
CONVECTION DURING THE PEAK DAYTIME HEATING HOURS ON SATURDAY AS
MODEL SOUNDINGS INDICATE SUBSTANTIAL CAPE...ALTHOUGH LESS THAN
PREVIOUS RUNS.  IN ADDITION...BULK SHEAR VALUES IN EXCESS OF 25KTS
WILL PROVIDE AT LEAST SOME POTENTIAL FOR ORGANIZED SEVERE
THUNDERSTORMS WITH THE MAIN THREATS BEING DAMAGING WINDS AND LARGE
HAIL.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AT 230 PM EDT FRIDAY...AN UPPER TROUGH WILL PROGRESS ACROSS THE
CENTER OF THE NATION ON SATURDAY NIGHT AND SUNDAY. THIS TROUGH WILL
CROSS THE OH AND TN VALLEYS ON SUNDAY NIGHT AND MONDAY...REACHING
THE SOUTHERN APPALACHIANS ON MONDAY NIGHT.

THE MODELS SHOW SOME LINGERING LOW LEVEL MOISTURE OVER OUR AREA ON
SATURDAY NIGHT IN THE WAKE OF A DEPARTING COLD FRONT. THE TRAILING
END OF THIS COLD FRONT RETURNS NORTH ACROSS THE GULF STATES ON
SUNDAY AND SUNDAY NIGHT...WITH A RESULTING INCREASE IN MOISTURE OVER
OUR AREA. MEANWHILE...THE REMAINS OF A COLD FRONT WILL APPROACH FROM
THE WEST ON SUNDAY NIGHT...CROSSING OUR ARE ON MONDAY. ADDITIONAL
MOISTURE ASSOCIATED WITH AN UPPER LOW OVER THE GREAT LAKES WILL MOVE
IN BEHIND THE REMAINS OF THE FRONT ON MONDAY NIGHT.

POPS WILL INCREASE THROUGH THE IN RESPONSE TO INCREASING MOISTURE
AND SOUTHERLY UPSLOPE FLOW AHEAD OF THE FRONTAL REMAINS...AND WILL
REMAIN ELEVATED AS INSTABILITY ASSOCIATED WITH THE UPPER LOW MOVES
OVER THE AREA ON MONDAY NIGHT. MAXIMUMS TEMPERATURES WILL RUN NEAR
NORMAL...WITH MINIMUMS INCREASING ABOVE NORMAL AS MOISTURE INCREASES.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AT 230 PM EDT FRIDAY...AN UPPER LOW WILL BE OVER THE GREAT LAKES
EARLY TUESDAY...WITH A TROUGH EXTENDING SOUTH TO FL. THE TROUGH AXIS
MOVES TO THE EAST COAST ON WEDNESDAY...WHILE AN UPPER RIDGE MOVES
SLOWLY EAST ACROSS THE ROCKIES AND THE PLAINS. THE UPPER TROUGH AXIS
MOVES LITTLE ON THURSDAY...WHILE THE CLOSED LOW MOVES INTO EASTERN
CANADA...AND A WELL DEFINED SHORTWAVE MOVES INTO THE OH RIVER
VALLEY. ON FRIDAY THE SHORTWAVE CROSSES THE CENTRAL APPALACHIANS.

A COLD FRONT WILL APPROACH OUR AREA ON MONDAY NIGHT...CROSSING THE
AREA TUESDAY. THE FRONT STALLS TO OUR SOUTH ON WEDNESDAY...THEN
LIFTS NORTH ACROSS OUR AREA AS A WARM FRONT ON WEDNESDAY NIGHT.
ANOTHER COLD FRONT WILL APPROACH FROM THE NORTHWEST ON THURSDAY...
CROSSING THE AREA ON THURSDAY NIGHT...BECOMING NEARLY STATIONARY
SOUTH OF OUR AREA ON FRIDAY. THESE FRONTS SHOULD KEEP ACTIVITY GOING
FOR MOST OF THE MEDIUM RANGE PERIOD. TEMPERATURES WILL RUN AROUND
NORMAL.

&&

.AVIATION /02Z SATURDAY THROUGH WEDNESDAY/...
AT KCLT...SOLID MVFR TO PERHAPS HIGH END IFR CONDITIONS WILL PREVAIL
THROUGH THE TAF PERIOD.  IN THE SHORT TERM...KEPT PREVIOUS TEMPO
LINE IN ASSOCIATION WITH ONGOING CONVECTION APPROACHING THE
AIRFIELD.  OTHERWISE...KEPT EITHER VCSH OR SHRA IN THE TAF THROUGH
THE OVERNIGHT HOURS AS GUIDANCE CONTINUES TO INDICATE SHOWER
ACTIVITY IN RESPONSE TO UPPER SHORT WAVE PASSING THROUGH.  CIGS WILL
REMAIN LOW THROUGH THE EVENING BEFORE LIFTING OUT TO VFR BY AROUND
THE 15Z TIMEFRAME SATURDAY MORNING.  MODEL SOUNDINGS INDICATE MODEST
INSTABILITY ACROSS THE NC PIEDMONT TOMORROW AFTERNOON...THUS KEPT
PROB30 FOR TSRA.

ELSEWHERE...MVFR TO IFR CONDITIONS WILL PREVAIL WITH THE ONLY
EXCEPTIONS BEING EARLY IN THE PERIOD WHERE KAVL COULD SEE VISB LOWER
THAN 1SM ASSOCIATED WITH FOG.  THIS LOWER VISB SHOULD NOT LAST LONG
THEREFORE ADDED TEMPO FOR 2HRS BEGINNING AT 00Z.  OTHERWISE...IN THE
NEAR TERM AT KGMU AND KGSP...ADDED RESPECTIVE 2HR TSRA TEMPO GROUPS
FOR AN ADVANCING LINE OF CONVECTION.  BEYOND THAT...LOOK FOR CIGS TO
REMAIN LOW END MVFR THROUGH THE MORNING.  AS WITH KCLT ABOVE...KEPT
MENTION OF SHRA OVERNIGHT AT ALL SITES.  CONDITIONS WILL IMPROVE
LATE SATURDAY MORNING ALLOWING CIGS TO RAISE TO VFR LEVELS.  DUE TO
MODEL INDICATED INSTABILITY...KEPT PROB30 GROUPS IN FOR ALL
SITES...HOWEVER IT LOOKS AS IF THE HIGHEST PROBABILITY WILL BE IN
THE HIGHER TERRAIN AND THE NC PIEDMONT.

OUTLOOK...SHRA/TSRA SHUD EXIT TO THE EAST SATURDAY MORNING...AS
DRIER CONDITIONS SPREAD ACROSS THE CAROLINAS THIS WEEKEND.
HOWEVER...AFTERNOON HEATING WILL TRIGGER AT LEAST SCATTERED SHOWERS
AND THUNDERSTORMS DURING THE AFTERNOON...ESPECIALLY OVER THE
MOUNTAINS. A COLD FRONT WILL ARRIVE LATE MONDAY ASSOCIATED WITH MORE
WIDESPREAD SHOWERS AND STORMS.
