THE TROUGH AXIS OF A LONG WAVE TROUGH IS SWINGING THROUGH MIDDLE
TN. THIS HAS BROUGHT SOME LIGHT SNOW SHOWERS TO THE PLATEAU WITH
SOME MINOR ACCUMULATION MAINLY IN THE FAR NORTHEAST PART OF THE
AREA. ANY LINGERING SNOW SHOWERS WILL DIMINISH OVER THE NEXT HOUR
WITH DRY WEATHER THIS AFTERNOON. CLOUD COVER WILL DIMINISH FROM
WEST TO EAST THROUGHOUT THE AFTERNOON AND MOST OF THE AREA WILL
GET TO SEE THE SUN BEFORE SUNSET. COLD AIR HAS SETTLED IN BEHIND
THE TROUGH AND THAT WILL KEEP HIGHS IN THE 30S FOR TODAY. CLEAR
AND COOL TONIGHT WITH LOWS IN THE TEENS TO LOWER 20S.
UPPER LEVEL FLOW BECOMES ZONAL SATURDAY WITH SURFACE HIGH PRESSURE
BUILDING TO OUR SOUTH. THIS WILL BRING THE RETURN OF SOUTHERLY
WINDS AND WARM US BACK INTO THE 40S TO AROUND 50 FOR HIGHS.
LONG TERM
(SATURDAY NIGHT THROUGH NEXT FRIDAY)

A SHORT WAVE WILL DEVELOP WITHIN THE ZONAL FLOW SUNDAY AS A TROUGH
DIGS INTO THE GREAT LAKES. THIS WILL START TO PUSH MOISTURE NORTH
FROM THE GULF OF MEXICO AND PUSH A WARM FRONT NORTH SUNDAY INTO
SUNDAY NIGHT. THE WARM FRONT IS EXPECTED TO STAY TO OUR SOUTH AND
THAT WILL KEEP THE BULK OF THE PRECIP SOUTH OF US. SOME LIGHT
SHOWERS WILL BE POSSIBLE TOWARDS THE TN/AL BOARDER AHEAD OF THIS
FRONT MAINLY SUNDAY EVENING INTO SUNDAY NIGHT. RAIN TOTALS

NORTHWEST FLOW THEN DEVELOPS EARLY NEXT WEEK WITH HIGH PRESSURE
SETTING UP TO OUR SOUTH. HIGHS WILL REMAIN IN THE 40S TO AROUND 50
BOTH SUNDAY AND MONDAY BUT BY TUESDAY WE WILL START TO WARM WITH
THEM PUSHING WELL INTO THE 50S. WE LOOK TO STAY DRY THROUGH THE
MIDDLE OF THE WEEK BUT UNCERTAINTY IN THE FORECAST INCREASES LATE
WEEK. AN UPPER LEVEL LOW WILL LIFT OUT OF THE WEST AT SOME POINT
