AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN

.DISCUSSION...

NO SIGNIFICANT WEATHER IS EXPECTED OVER THE NEXT 7 DAYS.  I
MEAN...NONE.  TEMPERATURES WILL BE A COUPLE OF DEGREES BELOW NORMAL
FOR THE WORKWEEK BEFORE WARMING BACK INTO THE LOW 70S NEXT
WEEKEND...BUT FOR THE MOST PART...WE SHOULD REMAIN HIGH AND DRY.

IF THERE IS ANYTHING WORTH A MENTION IN THIS MORNING`S FORECAST
PACKAGE IT`S THIS REALLY IMPOTENT SHORTWAVE THAT IS DIVING SOUTHWARD
OUT OF CENTRAL CANADA.  CURRENTLY SITUATED OVER THE GREAT LAKES...
THE MOST SIGNIFICANT FEATURE ASSOCIATED WITH IT IS A MID-LEVEL CLOUD
DECK AND SCATTERED LIGHT RAIN STRETCHING SWWD FROM THE OHIO VALLEY
INTO THE MID-MISSISSIPPI VALLEY.  MOISTURE IS EXTREMELY LIMITED...
BUT WE MAY ALSO SQUEEZE OUT SOME LIGHT RAIN THIS AFTERNOON...WITH
THE BEST CHANCE ACROSS THE NORTHEAST. THE ONLY CHANGE I`LL MAKE TO
THE WHOLE POP FORECAST THIS MORNING IS TO ADD IN A SMALL POP FOR
TONIGHT. A SECONDARY TROUGH ASSOCIATED WITH THIS SYSTEM WILL MOVE
THROUGH THE STATE OVERNIGHT AND I WOULDN`T BE SURPRISED TO SEE
SOME WET PAVEMENT EARLY TUESDAY MORNING IN A FEW SPOTS AROUND
MIDDLE TN. AGAIN...NOT SIGNIFICANT...BUT WORTH A MENTION.

THIS SECONDARY TROUGH TONIGHT WILL DELIVER SLIGHTLY COOLER AND DRIER
AIR FROM CANADA FOR THE MIDDLE OF THE WEEK BEFORE WE START TO SLOWLY
REBOUND BACK TOWARDS NORMAL FOR THE WEEKEND.

THE REBOUND WILL BE DUE IN PART TO AN EXTENDED RANGE SYSTEM FOR THE
START OF NEXT WEEK.  BOTH THE GFS AND THE EURO ARE SHOWING THIS
SYSTEM AND WHILE NOT TOO POTENT...IT SHOULD HELP GET DEW POINTS
ELEVATED ALONG WITH THE AFTERNOON HIGHS.

.AVIATION...06Z TAF DISCUSSION.

BOUNDARY LAYER MOISTURE REMAINS FAIRLY HIGH AND THIS COULD
LEAD TO PERIODS OF MVFR FOG/HAZE THROUGH 12-13Z...LARGELY CSV.
OTHERWISE VFR CONDITIONS ARE EXPECTED. WINDS WILL REMAIN BELOW
10 MPH.
