AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
310 PM EDT THU JUN 14 2001

THE 12Z MODEL RUNS SHOW SOME INTERESTING DIFFERENCES IN HOW THEY ARE
HANDLING THE FATE OF THE SUBTROPICAL LOW NEAR THE NC COAST THIS
AFTERNOON. FOR THE SHORT TERM...THE ETA APPEARS TO HAVE THE RIGHT
IDEA IN MOVING IT SLOWLY OFF TO THE SOUTHEAST AND OFF THE COAST...
BASED ON SATELLITE IMAGERY. HOWEVER...THE AVN TAKES THE LOW SLOWLY
NORTHWARD ALONG THE COAST. AT THIS POINT...I AM NOT SURE WHAT
DIFFERENCE IT MAKES AS TO WHAT MODEL SOLUTION IS ULTIMATELY
CORRECT...SINCE THIS SYSTEM IS FAR ENOUGH TO THE EAST THAT ANY RAIN
BANDS CIRCULATING AROUND THE CENTER SHOULD MISS OUR AREA TO THE EAST.

INSTEAD...WEAK UPPER RIDGING IN BETWEEN THIS LOW AND AN UPPER TROF
OVER THE PLAINS WILL PERSIST THROUGH FRIDAY NIGHT...AS THE UPPER
TROF TO THE WEST LIFTS OUT TO THE GREAT LAKES. VERY LITTLE IN THE
WAY OF UPPER FORCING IS EXPECTED AS A RESULT. BY SATURDAY...WE ARE
LEFT WITH DIFLUENT UPPER FLOW ACROSS THE SOUTHERN APPALACHIANS WITH
A LARGE UPPER RIDGE NOSING IN FROM THE WEST. AT LOW LEVELS...THE ETA
MAINTAINS MOISTURE CONVERGENCE THROUGH THE PERIOD. THIS...AND ANY
MESOSCALE FORCING...WILL DRIVE ANY CONVECTIVE DEVELOPMENT THROUGH
SATURDAY. WITH NOTHING TO MOVE OUT THE LOW AND MID LEVEL MOISTURE...
WE SHOULD HAVE ENOUGH INSTABILITY AND LOW LEVEL FORCING TO GIVE US
SCATTERED SHOWERS AND THUNDERSTORMS ACROSS THE FORECAST AREA EACH
AFTERNOON AND EVENING...REGARDLESS OF THE LOW POPS SEEN ON GUIDANCE.
TEMPS WILL BE SUMMERLIKE.

AS FOR THE EXTENDED...WILL KEEP IT DRY FOR NOW WITH POPS BELOW
CLIMATOLOGY.

SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1136 AM EDT THU JUN 14 2001

UNSTABLE AIR AND PLENTIFUL MOISTURE SHOULD COMBINE TO PRODUCE VERY
STRONG THUNDERSTORMS OVER THE WESTERN CAROLINAS AND NORTHEAST
GEORGIA THIS AFTERNOON AND EVENING. AIR CONVERGING FROM A WESTERLY
FLOW ACROSS THE TENNESSEE VALLEY AND A NORTHEAST FLOW AROUND A LOW
PRESSURE AREA ALONG THE NORTH CAROLINA COAST... SHOULD AID IN THE
DEVELOPMENT OF STORMS.

THE HIGHEST POSSIBILITY FOR DAMAGING THUNDERSTORM WINDS EXIST OVER
PIEDMONT COUNTIES ALONG THE INTERSTATE 77 CORRIDOR. BUT STORMS
STRONG ENOUGH TO DO DAMAGE COULD OCCUR THROUGH OUT THE WESTERN
CAROLINAS AND EXTREME NORTHEAST GEORGIA. LARGE HAIL WILL ALSO BE
POSSIBLE WITH ANY STRONG STORMS.

THERE IS ALSO A THREAT OF LOCALLY HEAVY RAIN IN EXCESS OF THREE
INCHES FROM ANY SLOW MOVING STORMS THAT DEVELOP. SINCE THE GROUND IS
STILL MOIST FROM THE THUNDERSTORMS ON WEDNESDAY... FLOODING WILL BE
POSSIBLE FROM DOWNPOURS IN AREAS WHERE HEAVY RAIN PERSISTS.

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.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR FAVORITE MEDIA OUTLET FOR
THE LATEST UPDATES CONCERNING THIS POTENTIAL SEVERE WEATHER
SITUATION.
