SATELLITE SHOWS A WELL DEFINED S/WV MOVING INTO NRN MIDDLE
TENNESSEE WITH THE SFC ANALYSIS SHOWING A TROUGH ACROSS THE
PLATEAU.  AMS ALONG AND EAST OF THIS TROUGH CONTINUES TO
DESTABILIZE WITH A SCT-BKN LINE OF STORMS OVER THE PLATEAU. EXPECT
A NEARLY SOLID LINE OF STORMS TO MOVE ACROSS THE TN VALLEY...MTNS...
SW VA...SW NC REST OF THE AFTERNOON AND EVENING.  DUE TO LOWER
MID-LVL TEMPS AND DECENT LO LVL SPEED SHEAR...SOME OF THESE STORMS
COULD BECOME SEVERE WITH THE MAIN THREAT BEING DAMAGING WINDS
AND HAIL. ALSO...LOCALLY HEAVY RAINS ARE LIKELY.

I EXPECT SCATTERED SHOWERS TO CONTINUE OVER THE TN VALLEY AND MTNS
UNTIL MIDNIGHT...THEN SUBSIDENCE BEHIND EXITING TROUGH WILL AID
IN CLEARING THE SKIES OVER THE AREA. HOWEVER...DUE TO THE RECENT
RAINS/SATURATED GROUND AREAS OF FOG AND LO CLOUDS WILL LIKELY
REDEVELOP.  SOME OF THE FOG COULD BECOME DENSE...ESPECIALLY ACROSS
THE VALLEYS.

THE FOG AND LOW CLOUDS WILL DISSIPATE SUNDAY AS DRIER AIR FROM A SFC
HIGH OVER THE GREAT LAKES BUILDS INTO THE AREA. MOSTLY SUNNY TO
PARTLY CLOUDY SKIES ARE ANTICIPATED.

ANOTHER NRN STREAM TROUGH WILL MOVE ACROSS THE GREAT LAKES FOR MONDAY
ALLOWING A COLD FRONT TO MOVE TOWARD THE MISSISSIPPI RIVER VALLEY
BY LATE IN THE DAY. ALSO...SFC RIDGE WILL MOVE EAST ALLOWING WINDS
TO BECOME MORE SOUTHERLY. HOWEVER...SFC RIDGING EAST OF APPALACHIANS
WILL LIKELY KEEP BEST MOISTURE SOUTH OF THE REGION. SOME WIDELY
SCT SHOWER AND THUNDERSTORMS ARE POSSIBLE BY LATE AFTERNOON. OTHERWISE
CALL FOR PARTLY CLOUDY SKIES.

AS FOR TEMPS...GUIDANCE CLOSE AND REASONABLE FOR TONIGHT. WOULD FOLLOW
COOLER FAN LOWS FOR SUNDAY NIGHT. WOULD COMPROMISE ON HIGHS EACH DAY.
