AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1210 PM EDT FRI JUN 22 2012

.SYNOPSIS...
A WEAK COLD FRONT WILL CROSS THE REGION FROM THE NORTHWEST
TODAY...BUT STALL ACROSS THE SOUTHEAST PART OF THE FORECAST AREA
TONIGHT THROUGH SATURDAY. THIS FRONT WILL DISSIPATE ON SUNDAY...BUT
ANOTHER COLD FRONT WILL ARRIVE FROM THE NORTHWEST MONDAY THROUGH
MONDAY NIGHT. GENERALLY DRY SURFACE HIGH PRESSURE IS THEN EXPECTED
TUESDAY THROUGH THURSDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
1610 UTC UPDATE...WINDS WERE UPDATED WITH A BLEND OF THE 12Z NAM AND
THE 06Z ADJMAV. SKY WAS UPDATED FROM SATELLITE IMAGERY...AND POPS
FROM RADAR TRENDS.

AT 1000 EDT...MORNING UPPER AIR ANALYSIS SHOWED HIGHS CENTERED OVER
THE SOUTHERN ROCKIES AND OFF THE SOUTHEAST COAST...WITH A TROUGH
EXTENDING FORM HUDSON BAY TO THE TN VALLEY. A SHORTWAVE MOVING
THROUGH THIS TROUGH WAS NEAR THE SOUTHERN APPALACHIANS...WHILE
ANOTHER WAS UPSTREAM IN THE WESTERN GREAT LAKES. SURFACE ANALYSIS
PLACED A COLD FRONT IN THE TN VALLEY...AND A LEE TROUGH ALONG
INTERSTATE 85. RADAR SHOWS ISOLATED ACTIVITY AHEAD OF THE FRONT IN
SW VA. BOTH THE NAM AND GFS SHOW SUBSTANTIAL INSTABILITY TODAY...AND
A S THE COLD FRONT APPROACHES...CONVECTION IS EXPECTED TO BECOME
WIDESPREAD...SUPPORTING HIGH END POPS...ESPECIALLY IN THE MOUNTAINS.
ALTHOUGH SHEAR IS WEAK...DRY AIR IS AVAILABLE ALOFT FOR EVAPORATIVE
COOLING...SUPPORTING STRONG DOWNDRAFTS. MAXIMUM TEMPERATURES WILL BE
SEVERAL DEGREES ABOVE NORMAL IN A WARM PREFRONTAL AIR MASS.

AS THE FRONT SAGS SOUTH ACROSS THE AREA TONIGHT...THE FOCUS FOR
CONVECTION SHOULD SHIFT TO THE SOUTHERN HALF OF THE CWFA...ALTHOUGH
LACK OF SIGNIFICANT FORCING SHOULD RESULT IN DIMINISHING COVERAGE
WITH THE LOSS OF HEATING. MIN TEMPS SHOULD BE A LITTLE ABOVE
NORMAL.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 315 AM EDT FRIDAY...A 500 MB TROUGH IS EXPECTED TO LIFT EWD
ACROSS NEW ENGLAND ON SAT...WHILE A WEAK SURFACE COLD FRONT STALLS
ACROSS THE SE FRINGE OF THE FORECAST AREA. WEAK E TO SE UPSLOPE FLOW
BEHIND THE FRONT MAY COMBINE WITH LINGERING BOUNDARY LAYER MOISTURE
TO PRODUCE ISOLD TO SCT MTN CONVECTION SAT AFTN. THIS ACTIVITY COULD
ADVECT OUT INTO THE FOOTHILLS OR PIEDMONT THROUGH SAT EVENING.
MEANWHILE...UPPER LEVEL RIDGING WILL NOSE EWD FROM THE PLAINS. A
VORTICITY LOBE EMBEDDED IN THE DEVELOPING NW FLOW ALOFT MAY CROSS
THE SRN APPALACHIANS LATE SAT NIGHT/EARLY SUNDAY MORNING. ANY
MOISTURE WILL BE VERY SHALLOW AT THAT TIME...BUT WITH PROBABLY JUST
ENOUGH FORCING/MOISTURE TO PRODUCE ISOLD CONVECTIVE CONVERAGE DURING
THE OVERNIGHT/MORNING HOURS.

LOW LEVEL FLOW WILL LIKELY BECOME MORE SRLY THROUGH SUNDAY.
INSTABILITY WILL REMAIN FAIRLY MODERATE WITH DEWPOINTS REBOUNDING
SLIGHTLY. ISOLD AFTN COVERAGE IS EXPECTED...WITH SCATTERED COVERAGE
POSSIBLE NEAR THE BLUE RIDGE LATE SUN AFTN/EVENING. TEMPERATURES
WILL REMAIN ABOUT A CATEGORY ABOVE NORMAL.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
AS OF 325 AM FRIDAY...A COLD FRONT WILL APPROACH FROM THE NORTHWEST
ON MONDAY IN CONTINUED DEEP LAYER NW FLOW ACROSS THE REGION.
MOISTURE IS NOT EXPECTED TO BE VERY DEEP WITH THE APPROACHING
FRONTAL ZONE...BUT INSTABILITY SHOULD BE SUFFICIENT FOR SCT TSTM
COVERAGE WITH FROPA MON AFTN/EVENING...ESPECIALLY OVER WRN NC.

NW FLOW WILL THEN PERSIST TUE THROUGH THU AS A STRONG RIDGE HOLDS ON
ACROSS THE CENTRAL CONUS AND LOW PRES CUTS OFF OVER SRN QUEBEC.
IMPULSES IN THE NW FLOW WILL BE VERY DIFFICULT TO TIME THROUGH THE
PERIOD...BUT PROFILES SHOULD REMAIN FAIRLY DRY DURING THIS
TIMEFRAME. TEMPERATURES WILL BE NEAR NORMAL.

&&

.AVIATION /16Z FRIDAY THROUGH TUESDAY/...
AT KCLT/KHKY/KGSP/KGMU/KAND...A WEAK COLD FRONT WILL APPROACH THE
REGION FROM THE WEST TODAY...WHILE A SURFACE TROUGH WILL BECOME
BETTER ESTABLISHED OVER THE PIEDMONT. THESE FEATURES SHOULD PROVIDE
A FOCUS FOR AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS...AND PROB30
WILL BE RETAINED AT ALL TERMINALS. HOWEVER...DUE TO POLICY...PROB30
CANNOT BE INCLUDED BEFORE 21Z...BUT THERE IS POTENTIAL FOR TS
ANYTIME AFTER 17Z OR SO. I JUST DONT HAVE ENOUGH CONFIDENCE TO
INCLUDE A TEMPO ATTM. CONVECTION SHOULD BEGIN TO WANE THIS EVENING.
FOG/STRATUS WILL BE POSSIBLE LATE TONIGHT IN AREAS THAT RECEIVE
HEAVY RAINFALL.

AT KAVL...MVFR FOG WILL BE POSSIBLE AT THE START OF THE PERIOD...BUT
WILL IMPROVE QUICKLY IF IT DOES INDEED DEVELOP. AN APPROACHING COLD
FRONT WILL RESULT IN DEVELOPMENT OF NUMEROUS SHOWERS AND STORMS OVER
THE MOUNTAINS LATER TODAY. A TEMPO HAS BEEN INCLUDED FOR TSRA
BETWEEN 17 AND 21Z. PROB30 GROUPS WILL BE CARRIED FROM 21Z THROUGH
EARLY EVENING. FOG/STRATUS WILL BE POSSIBLE LATE TONIGHT IF HEAVY
RAINFALL DEVELOPS AT THE TERMINAL THIS AFTERNOON.

OUTLOOK...A WEAK FRONTAL BOUNDARY WILL REMAIN IN THE AREA OVER THE
WEEKEND THROUGH MONDAY AND WILL CONTINUE TO BE A FOCUS FOR MAINLY
AFTERNOON AND EVENING THUNDERSTORMS. EARLY MORNING FOG WILL ALSO BE
POSSIBLE IN THE MOUNTAIN VALLEYS. DRIER WEATHER MAY RETURN BY
TUESDAY.
