AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
315 PM EDT MON SEP 1 2014

.SHORT TERM (TONIGHT AND TUESDAY)...ATMOSPHERE A BIT CAPPED OFF THIS
AFTERNOON WITH A SUPPRESSED APPEARANCE NOTED IN SATELLITE IMAGERY.
IT APPEARS STORMS ARE FIRING ON THE TERRAIN BUT WEAKEN LACKING
OROGRAPHIC SUPPORT IN THE VALLEY. STAYED WITH ISOLATED PROBABILITY
INTO THE EVENING MOST SPOTS AS SOME OF THE STORMS DRIFT INTO THE
VALLEY BEFORE WEAKENING. PERHAPS A LITTLE BETTER CHANCE FOR A SHOWER
OR THUNDERSTORM ON TUESDAY AS NORTH CENTRAL AMERICA UPPER TROUGHING
CONTINUES TO GRADUALLY WORK ITS WAY EAST ACROSS THE UPPER MIDWEST.
AS THIS OCCURS A WEAK COOL FRONTAL BOUNDARY WILL DROP SOUTH INTO THE
NORTHERN REACHES OF THE FORECAST AREA ENHANCING CONVECTIVE POTENTIAL
MAINLY NORTH OF I-40. STAYED VERY NEAR GUIDANCE BLEND FOR MINS/MAXES.

.LONG TERM (TUESDAY NIGHT THROUGH MONDAY)...WEAK RIDGING ALOFT WILL
BE THE DOMINANT FEATURE THROUGH THE PERIOD. THE WARMTH ASSOCIATED
WITH THE RIDGE WILL WORK UPON LOW LEVEL MOISTURE THAT WILL REMAIN IN
PLACE...TO PROMOTE DIURNAL CONVECTION EACH DAY. BUT A WEAK FRONTAL
PASSAGE EARLY THIS COMING WEEKEND WILL PROBABLY BRING A BIT BETTER
COVERAGE OF CONVECTION AROUND SATURDAY.
