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

.DAY ONE...TONIGHT...

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH MONDAY...

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 CHANCE FOR A FEW THUNDERSTORMS FOR POINTS
MAINLY SOUTH OF INTERSTATE 40. AT THIS TIME...INSTABILITY IS
MARGINAL AND IS NOT EXPECTED TO PRODUCE STRONG TO SEVERE
THUNDERSTORMS. HOWEVER...AREAS OF HEAVY RAINFALL IS
EXPECTED...ESPECIALLY ACROSS THE PLATEAU AND SOUTHEAST TENNESSEE.

THE CHANCE FOR ANY SIGNIFICANT SNOW LATER WEDNESDAY NIGHT INTO
CHRISTMAS MORNING LOOKS LESS LIKELY WITH COMPUTER MODELS INDICATING
THE COLDER AIR BUILDING IN ON THE BACK SIDE OF THE UPPER LEVEL
TROUGH ARRIVES LATER THAN PREVIOUSLY THOUGHT. ALSO...THE TRAILING
UPPER LEVEL FEATURE MOVES THROUGH RATHER QUICKLY WITH DRY AIR
SHUTTING DOWN PRECIPITATION IN MOST LOW ELEVATION AREAS EARLY ON
CHRISTMAS MORNING. SO THERE MAY BE A FEW SNOW FLURRIES FLYING IN
THE LOWER ELEVATIONS LATER WEDNESDAY NIGHT INTO EARLY CHRISTMAS
MORNING WITH LITTLE CHANCE OF ANY ACCUMULATION.

THE BEST CHANCE FOR ANY MINOR ACCUMULATION...AROUND AN
INCH...WOULD BE IN THE HIGHER TERRAIN...MAINLY ABOVE 3000 FEET
WHERE COLDER TEMPERATURES AND OROGRAPHIC LIFT SHOULD HELP GENERATE
A BETTER LIKELIHOOD OF SNOW.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT NEEDED AT THIS TIME.
