.DISCUSSION...RADAR INDICATING MOST OF THE SHOWERS AND THUNDERSTORMS
EAST OF OUR AREA ALONG SURFACE FRONT...BUT MODELS IN PRETTY GOOD
AGREEMENT ON BRINGING UPPER TROUGH IN FROM THE WEST.  ALSO BRINGING
GOOD MOISTURE WITH IT...SO WILL GO WITH LIKELY POPS FOR TODAY.
MODELS ALSO INDICATING NEGATIVES LIS AS THE TROUGH PUSHES IN...SO
WILL KEEP MENTION OF THUNDER FOR THIS AFTERNOON.  A FEW REPORTING
STATIONS REPORTING PATCHY DENSE FOG...NOT WIDESPREAD ENOUGH FOR AN
ADVISORY.  UPPER TROUGH CONTINUES TO DEEPEN TONIGHT...WITH
TEMPERATURES COOL ENOUGH TO SNOW IN THE HIGHER ELEVATIONS LATE
TONIGHT AND SATURDAY MORNING.  PROBABLY WONT SEE MUCH ACCUMULATION
WITH THE WARM SURFACE AND BOUNDARY LAYER TEMPERATURES MARGINAL FOR
ACCUMULATION...WITH THE BEST CHANCES IN THE HIGHER ELEVATIONS.
BELOW 2000 FEET SHOULD BE ALL LIQUID.  SHOWERS SHOULD BE ENDING BY
SATURDAY NIGHT...WITH ANOTHER SHOT FOR MIXED PRECIP IN THE
MOUNTAINS...TOO DRY FOR ANY ACCUMULATIONS.  DRY WEATHER RETURNS
SUNDAY.  ANOTHER WEAK FRONT MOVES THROUGH SUNDAY NIGHT...WILL KEEP
20 POPS FOR THE CENTRAL AND NORTHERN ZONES.

...ACCUMULATING SNOWFALL POSSIBLE ACROSS THE HIGHER ELEVATIONS LATE
TONIGHT INTO SATURDAY...

A STRONG UPPER-LEVEL SYSTEM WILL SWING ACROSS THE SOUTHERN
APPALACHIAN REGION TONIGHT AND SATURDAY...BRINGING COLDER
TEMPERATURES (ESPECIALLY ALOFT).  THIS UPPER-LEVEL SYSTEM WILL
TRIGGER SCATTERED RAIN SHOWERS ACROSS MOST OF THE REGION TONIGHT
THROUGH SATURDAY.  BECAUSE OF THE COLDER TEMPERATURES ALOFT...
SCATTERED SNOW SHOWERS ARE EXPECTED TO DEVELOP AFTER MIDNIGHT
TONIGHT ACROSS THE HIGHER ELEVATIONS ABOVE 2000 FEET.  RIGHT NOW...
IT APPEARS THAT TEMPERATURES WILL BE TOO WARM FOR SNOW SHOWERS IN
THE VALLEY AREAS BELOW 2000 FEET.

ACROSS THE NORTHERN CUMBERLAND PLATEAU...RAIN SHOULD MIX WITH SNOW
AFTER MIDNIGHT TONIGHT INTO SATURDAY MORNING. HOWEVER...NO SNOW
ACCUMULATIONS ARE EXPECTED SINCE THE GROUND TEMPERATURES ARE STILL
WARM FROM THE RECENT MILD WEATHER. RIGHT NOW...IT APPEARS THAT LIGHT
SNOWFALL ACCUMULATIONS OF ONE TO THREE INCHES WILL BE POSSIBLE ACROSS
THE HIGHER ELEVATIONS ABOVE 2000 FEET BY SATURDAY EVENING.

PLEASE STAY TUNED TO NOAA WEATHER RADIO...OR YOUR FAVORITE TELEVISION
OR RADIO STATION...FOR LATER STATEMENTS REGARDING THIS DEVELOPING
WINTER WEATHER SITUATION.
