.DISCUSSION...

AS AN UPPER TROUGH CENTERED OVER THE CENTRAL PLAINS MOVES EAST THIS
AFTERNOON AND OVERNIGHT IT WILL INFLUENCE SHOWERS AND THUNDERSTORMS
TO CONTINUE THEIR TREK NORTHWARD THROUGH MIDDLE TN. HRRR IS FORECASTING
SCATTERED AFTERNOON ACTIVITY TO MOVE INTO KENTUCKY AND ANOTHER
WAVE OF PRECIP TO SPREAD INTO MIDDLE TENNESSEE FROM THE SOUTH
BEFORE MIDNIGHT. PWAT VALUES WILL BE AROUND 1.5 INCHES FOR SEVERAL
HOURS OVERNIGHT TONIGHT. WITH THE GROUND ALREADY SATURATED FROM
THIS PAST WEEK`S RAINFALL...WE COULD SEE CREEKS AND STREAMS RISE
PRETTY QUICKLY DURING THE OVERNIGHT HOURS...WATCH FOR MINOR
FLOODING IN LOW LYING AREAS AND PONDING OF WATER ON ROADWAYS
OVERNIGHT. WHILE THERE MAY BE STORMS AROUND...NOT EXPECTING
ANYTHING STRONG OR SEVERE TONIGHT.

BETWEEN LATE SUNDAY MORNING AND EARLY AFTERNOON THE DEEPEST
MOISTURE WILL PUSH NORTH OF OUR AREA. LINGERING CLOUD
COVER...ESPECIALLY OVER THE NORTHEASTERN PORTION OF THE CWA MAY
INHIBIT INSTABILITY...BUT CLOUDS SHOULD BREAK UP ENOUGH DURING
THE AFTERNOON HOURS TO ALLOW FOR TEMPERATURES TO WARM INTO THE LOW
70S ALONG THE CUMBERLAND PLATEAU AND MID 70S ELSEWHERE. THIS
SHOULD BE WARM ENOUGH TO INITIATE ISOLATED TO SCATTERED STORMS
THROUGHOUT THE AFTERNOON. CURRENTLY SPC HAS THE MID-STATE IN A
SLIGHT RISK FOR SEVERE THUNDERSTORMS FOR SUNDAY AFTERNOON THROUGH
SUNDAY NIGHT. THE MAIN THREAT WITH ANY STORMS DURING THIS TIME
FRAME WILL BE DAMAGING WINDS AND HAIL. WE COULD SEE A COUPLE OF
ROUNDS OF THUNDERSTORMS OVERNIGHT SUNDAY NIGHT AHEAD OF A
SHORTWAVE AND ITS ASSOCIATED SURFACE LOW...WHICH STRENGTHEN OVER
SOUTHERN ILLINOIS AND HEAD NORTHEAST ON MONDAY.

THE FRONTAL PASSAGE ASSOCIATED WITH THE AFOREMENTIONED LOW WILL
OCCUR ON MONDAY AND WILL ALLOW FOR TEMPERATURES TO COOL INTO THE
40S OVERNIGHT MONDAY NIGHT. ALL PRECIP SHOULD PUSH EAST OF THE
TENNESSEE VALLEY TUESDAY NIGHT. A SURFACE HIGH MOVES IN ON TUESDAY
AND GIVES US A MUCH NEEDED DRY AND RELATIVELY COOL DAY WITH HIGH
TEMPERATURES IN THE MID 60S.

THE NEXT CHANCE OF PRECIP ENTERS THE FORECAST WEDNESDAY EVENING AS
A WEAK FRONT BRINGS A CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH
THE AREA. COULD SEE A BREAK ON FRIDAY AS THAT MOISTURE PUSHES
SOUTH...THEN ANOTHER SURFACE LOW BRINGS ADDITIONAL THUNDERSTORM
CHANCES FRIDAY NIGHT.
