AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
259 PM EDT SAT AUG 1 2015

.SHORT TERM /TONIGHT AND SUNDAY/...
A VERY QUIET FORECAST IN THE NEAR-TERM...AS A SURFACE HIGH IS
MAINTAINING THE CLEAR AND BEAUTIFUL SUNNY WEATHER OVER THE REGION
THIS AFTERNOON. WITH RH VALUES IN THE 40 PERCENT RANGE...IT
CERTAINLY FEELS MUCH DIFFERENT KICKING THE MONTH OF AUGUST THAN IT
DID ENDING JULY. AMPLE SUNSHINE HAS ALLOWED TEMPERATURES TO CLIMB
INTO THE UPPER 80S TO AROUND 90 DEGREES AS OF 3 PM EDT. HOWEVER...
WITH THE CLEAR AND CALM CONDITIONS...GOOD RADIATIONAL COOLING WILL
TAKE PLACE AFTER SUNSET...AND THE DRY CONDITIONS WILL ALLOW LOWS TO
BOTTOM OUT IN THE UPPER 50S TO MID 60S...VERY COMFORTABLE FOR THIS
TIME OF YEAR. A SIMILAR SET-UP IS EXPECTED FOR TOMORROW...WITH
HIGHS PERHAPS A DEGREE OR TWO HIGHER.

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
A COUPLE OF WEAK IMPULSES RIDING THROUGH THE FLOW ALOFT MONDAY AND
TUESDAY MAY BRING ISOLATED CONVECTION OVER FAR NORTHERN LOCATIONS
MONDAY AND TUESDAY. HOWEVER...THE DRY AND TRANQUIL WEATHER PATTERN
WILL CONTINUE OVER MUCH OF THE AREA FOR THIS PERIOD. THEN...WE WILL
TRANSITION INTO A MORE UNSETTLE PATTERN FOR THE REST OF THE EXTEND.
WEDNESDAY...AN APPROACHING SYSTEM WILL PROVIDE A CHANCE OF
CONVECTION ACROSS THE REGION. THERE REMAINS SOME DISAGREEMENT ON
DETAILS THROUGH THE REMAINDER OF THE PERIOD...BUT THE TREND IS TO
BRING IN MAIN SYSTEM FOR THE PERIOD THROUGH AROUND THE THURSDAY
TIME FRAME FOR LIKELY TO HIGH CHANCE POPS. A SERIES OF SHORT WAVES
CONTINUE TO DROP IN THROUGH THE REST OF THE EXTENDED FOR A CHANCE
OF CONVECTION FRIDAY AND SATURDAY. AS FOR TEMPERATURES...THEY
SHOULD BE AROUND SEASONAL NORMS FOR THE PERIOD.
