THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHWEST NORTH
CAROLINA...EAST TENNESSEE AND SOUTHWEST VIRGINIA.

.DAY ONE...THIS AFTERNOON AND TONIGHT...

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY...

A STORM SYSTEM WILL MOVE ACROSS THE TENNESSEE VALLEY AND SOUTHERN
APPALACHIANS IMPACTING THE REGION TUESDAY THROUGH WEDNESDAY NIGHT.
WARM AIR WILL STREAM NORTH ACROSS THE SOUTHERN APPALACHIAN REGION
KEEPING PRECIPITATION ASSOCIATED WITH THE SYSTEM IN THE FORM OF
RAIN SHOWERS AND A SLIGHT CHANCE FOR A FEW THUNDERSTORMS FOR
POINTS MAINLY SOUTH OF INTERSTATE 40 FOR TUESDAY AFTERNOON AND
EVENING. INSTABILITY IS WEAK BUT SHEAR AND HELICITY ARE ROBUST.
THERE IS A CHANCE FOR A FEW STORMS TO BECOME STRONG ACROSS OUR
SOUTHERN MOST AREAS. HOWEVER...THE AIR WILL BECOME COLD ENOUGH ON
THE BACK SIDE OF THE STORM SYSTEM THAT BY LATE WEDNESDAY EVENING
RAIN SHOULD CHANGE TO SNOW.

THEREFORE...THERE IS THE POSSIBILITY OF SOME SNOW BY LATE
CHRISTMAS EVE CONTINUING INTO EARLY CHRISTMAS MORNING. THE BEST
CHANCE FOR SOME MINOR ACCUMULATION WOULD BE IN THE HIGHER TERRAIN
WHERE COLDER TEMPERATURES AND OROGRAPHIC LIFT SHOULD HELP GENERATE
A BETTER LIKELIHOOD OF SNOW. NO ACCUMULATION EXPECTED ACROSS THE
LOWER ELEVATIONS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT NEEDED AT THIS TIME.
