AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
130 PM CDT FRI JUN 15 2001

CURRENTLY, ACTIVE WEATHER CONTINUES TO FILL IN ALONG PRE-FRONTAL
TROUGH, WITH COLD FRONT NOW PROGRESSING THROUGH THE MISSISSIPPI
VALLEY. AIR MASS REMAINS MUGGY, WITH TEMPERATURES WARMING INTO THE
80S AND DEW POINT IN THE LOWER 70S.

MODELS SHOW COLD FRONT PASSING THROUGH THE MID STATE LATE THIS
AFTERNOON AND EARLY EVENING, WITH RATHER ABRUPT DRYING AS HIGH
PRESSURE BEGINS TO BUILD IN BEHIND THE FRONT. SKIES SHOULD CLEAR OUT
DURING THE EVENING, ALTHOUGH WINDS WILL STAY UP DUE TO STRONG SURFACE
PRESSURE GRADIENT. MODEL SOUNDINGS SHOW VERY DRY ATMOSPHERE IN PLACE
THROUGH SUNDAY, MAKING FOR A VERY PLEASANT AND LESS HUMID WEEKEND.
EXPECT A WARMING TREND BY THE EARLY PART OF THE WEEK, ALTHOUGH MODEL
GUIDANCE VALUES, ESPECIALLY NGM-BASED MOS, APPEAR TOO WARM (WHEN
COMPARED TO THE MASSIE-ROSE LOW LEVEL THICKNESS SCHEME VALUES).
BELIEVE MORE SEASONAL VALUES ARE MORE REALISTIC, GIVEN NORTHERLY FLOW
BEHIND THE FRONT.

EXPECT ONLY MINOR ADJUSTMENTS TO UPCOMING ZONE PACKAGE. WILL LEAVE
THUNDERSTORMS IN THE EXTENDED FORECAST FOR WEDNESDAY AND THURSDAY,
WITH EVEN MORE WIDESPREAD ACTIVITY FOR FRIDAY AS MRF BRINGS A COLD
FRONT THROUGH THE MID STATE.
