.PREV DISCUSSION... /ISSUED 227 PM CDT WED AUG 27 2014/

DISCUSSION...IT WAS A TYPICAL AUGUST AFTERNOON IN MID TN WITH
WARM AND HUMID CONDITIONS UNDER PARTLY SUNNY SKIES. DEW POINTS HAD
NOT DROPPED AS WE HAD HOPED. THE NORTHWEST HALF OF MID TN WAS
ACTUALLY A LITTLE MORE HUMID THAN YESTERDAY AT THIS TIME. RADAR
SHOWED A FEW THUNDERSTORMS DEVELOPING IN THE DEEPER MOISTURE OVER
OUR NORTHWEST COUNTIES.

THE THUNDERSTORMS IN THE NORTHWEST ARE HEAT DRIVEN AND SHOULD DIE
OUT QUICKLY WITH SUNSET. OTHERWISE...THE NIGHT WILL BE MUGGY WITH
CLEAR TO PARTLY CLOUDY SKIES. LOWS WILL RANGE FORM THE MID 60S TO
LOWER 70S. SOME PATCHY GROUND FOG IS EXPECTED AGAIN TONIGHT.

FOR THE NEXT COUPLE OF DAYS...THE CURRENT HIGH PRESSURE ALOFT WILL
REMAIN IN CONTROL OVER THE REGION. HIGHS WILL BE MOSTLY IN THE
LOWER 90S WITH LOWS AROUND 70. RAIN CHANCES APPEAR QUITE LOW...BUT
WE WILL KEEP 20 POPS OVER THE NORTH ON THURSDAY AS A WEAK BOUNDARY
DIPS ACROSS THE OHIO VALLEY.

FOR THE LABOR DAY WEEKEND...A TROUGH WILL APPROACH...RESULTING IN
A DEEP SOUTH SOUTHWEST FLOW OF MOIST AIR. MODELS SUGGEST A COUPLE
OF IMPULSES WILL CROSS THE AREA...RESULTING IN A GOOD CHANCE FOR
SHOWERS AND THUNDERSTORMS. IT DOES NOT LOOK LIKE THE ENTIRE
WEEKEND WILL BE A WASHOUT...BUT THERE WILL BE SOME PERIODS OF
THUNDERSTORMS WITH THE POTENTIAL FOR LOCALLY HEAVY DOWNPOURS.
RIGHT NOW...MODEL BLENDING SHOWS THE GREATEST RAIN POTENTIAL
SATURDAY NIGHT INTO SUNDAY MORNING. OTHERWISE...THE WEEKEND WILL BE
SEASONABLY WARM AND HUMID. MOISTURE WILL DECREASE ON LABOR
DAY...SO RAIN CHANCES WILL DIMINISH TO AROUND 30 PERCENT.

THROUGH MIDWEEK...WARM AND HUMID CONDITIONS WILL PERSIST WITH A
CHANCE FOR THUNDERSTORMS EACH DAY AS A SURFACE BOUNDARY APPROACHES
FROM THE NORTHWEST.
