AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
320 PM EDT MON JUL 21 2003

ISOLATED TO WIDELY SCATTERED CONVECTION CONTINUES TO DEVELOP ACROSS
THE WESTERN CAROLINAS AND NORTHEAST GEORGIA...IN AN AIRMASS
CHARACTERIZED BY CAPES RANGING FROM 2500 IN THE MOUNTAINS...TO 3500
J/KG ALONG THE EASTERN PERIPHERY OF THE CWFA. WE WILL ADVERTISE
CHANCE POPS ACROSS THE ENTIRE REGION EARLY THIS EVENING TO HANDLE
THIS ACTIVITY. WITH MODERATE TO HIGH INSTABILITY AND STEEP MID LEVEL
THETA-E LAPSES...EXPECT THAT WE WILL SEE A FEW WET MICROBURSTS HERE
AND THERE THIS EVENING. OF GREATER CONCERN IS THE RATHER STRONG MCS
CURRENTLY ADVANCING OUT OF SOUTHERN KENTUCKY...INTO NORTHERN
MIDDLE/NORTHEAST TENN. THE UNSTABLE AIRMASS AHEAD OF THIS FEATURE
AND CORFIDI VECTORS/THERMAL WIND PROGS SHOULD SUPPORT IT INTO OUR NC
MNTNS DURING THE MID/LATE EVENING...AND WILL CARRY LIKELY POPS THERE
DURING THIS TIMEFRAME. HOWEVER...WITH LACK OF UPPER SUPPORT/ADEQUATE
SHEAR...THE MCS SHOULD HAVE DIFFICULTY MAINTAINING ITSELF EAST OF THE
MOUNTAINS...SO POPS WILL BE HELD IN THE CHANCE RANGE THERE.

TUESDAY...PERSISTENT EAST COAST TROUGH AMPLIFIES AS A STRONG SW
MOVES INTO THE BASE OF THE TROUGH...AND DEEP LAYER W/SW FLOW
STRENGTHENS QUITE NICELY IN RESPONSE...ESP FOR THIS TIME OF YEAR.
ALTHOUGH INCREASE IN CLOUD COVER AND RATHER WEAK MID LEVEL LAPSE
RATES WILL PRECLUDE THE DEVELOPMENT OF A TERRIBLY UNSTABLE
AIRMASS...EXPECT CONVECTION TO REDEVELOP TOMORROW AFTERNOON WITHIN
LEE TROUGH...AND/OR PERHAPS ALONG OUTFLOW BOUNDARY(S) LEFT BEHIND
FROM TONIGHTS MCS. SHEAR WILL BE MORE THAN ADEQUATE FOR SOME OF
THIS ACTIVITY TO ORGANIZE INTO SEVERE MULTICELL CLUSTERS...AND WE
WILL ADVERTISE HIGH CHANCE TO LIKELY POPS TOMORROW AFTERNOON. AS THE
SW TROUGH AND ASSOCIATED FRONTAL BOUNDARY MOVES INTO THE AREA
TUESDAY EVENING/NIGHT...AND THE REGION COMES UNDER THE INFLUENCE OF
THE RIGHT ENTRANCE REGION OF AN 80KT H2 JET...SUSPECT THAT WE WILL
SEE A LARGE MCS AFFECT THE CWFA DURING THIS TIME...AND LIKELY POPS
WILL BE MAINTAINED FOR THIS PERIOD. ASSUMING THAT THE AIRMASS ISNT
COMPLETELY WORKED OVER FROM TOMORROW AFTERNOONS CONVECTION...THERE
SHOULD BE A CONTINUED THREAT OF SEVERE WEATHER INTO TUESDAY NIGHT.

HAVE LINGERED POPS INTO WEDNESDAY AND PART OF THURSDAY...ESPECIALLY
ACROSS THE EAST...AS THE BOUNDARY BEGINS TO STALL IN OR NEAR THE
AREA. FOR FRIDAY THROUGH SUNDAY...THE FORECAST WILL REMAIN FREE OF
POPS...AS THE EAST COAST TROUGH DEAMPLIFIES AND THE BOUNDARY SLOWLY
WASHES OUT OVER THE SOUTHEAST. POPS RETURN TO THE FORECAST FOR
MONDAY...AS MEDIUM RANGE MODELS HINT AT A REAMPLIFICATION OF THE
TROUGH.

.GSP...
GA...NONE.
NC...NONE.
SC...NONE.

SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
130 PM EDT MON JUL 21 2003

...A FEW SEVERE THUNDERSTORMS POSSIBLE THIS AFTERNOON AND TONIGHT...

THE ATMOSPHERE WILL BECOME VERY UNSTABLE AGAIN THIS AFTERNOON ACROSS
THE WESTERN CAROLINAS AND EXTREME NORTHEAST GEORGIA. SCATTERED
THUNDERSTORMS WILL DEVELOP THIS AFTERNOON AND THIS EVENING. A FEW OF
THE THUNDERSTORMS SHOULD GROW LARGE ENOUGH TO PRODUCE SEVERE
WEATHER...MAINLY IN THE FORM OF DAMAGING WIND GUSTS. LARGE HAIL IS
ALSO POSSIBLE WITH A FEW STORMS.

ANOTHER MORE ORGANIZED AREA OF THUNDERSTORMS WILL APPROACH THE
MOUNTAINS FROM THE WEST LATE IN THE DAY. IF THESE STORMS HOLD
TOGETHER...THE POTENTIAL WILL EXIST FOR ADDITIONAL SEVERE
THUNDERSTORMS OVER THE NORTH CAROLINA MOUNTAINS DURING THE EVENING
HOURS. THIS SECOND BATCH OF THUNDERSTORMS COULD MOVE OUT ACROSS THE
FOOTHILLS AND PIEDMONT LATE TONIGHT...BUT THERE IS STILL MUCH
UNCERTAINTY ABOUT THAT POSSIBILITY.

SPOTTER GROUPS SHOULD BE PREPARED TO ACTIVATE QUICKLY LATE THIS
AFTERNOON AND THIS EVENING. DISPATCHERS SHOULD ENSURE COUNTY
EMERGENCY MANAGEMENT OFFICIALS ARE AWARE OF THIS INFORMATION.
