AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
942 AM EDT FRI AUG 29 2014

.DISCUSSION...NO SIGNIFICANT CHANGES GENERALLY FROM YESTERDAY...EVEN
SIMILAR AREAS OF FOG/LOW CLOUDS NOTED ACROSS THE SEQUATCHIE VALLEY
IN SE TN AND ALSO A FEW OTHER LAKES OR STREAMS. THE WEAK FRONTAL
BOUNDARY HARD TO PLACE WITH RATHER HOMOGENOUS DEW POINT TEMPS ACROSS
THE FORECAST AREA.

NOT SURE HOW MUCH OF A FACTOR THE FRONTAL BOUNDARY WILL BE FOR THIS
AFTERNOON...BUT PROBABLY CAN COUNT ON WEAK LOW LEVEL CONVERGENCE IN
THE HIGHER TERRAIN OF NE TN AND SW VA. SPOTTY SHOWERS OR TSRA SHOULD
BE ABLE TO POP ONCE WE OVERCONME SOME WEAK CAPPING...(NOTED ON 12Z
OHX AND RNK SOUNDINGS).

FORECAST GRIDS AND PRODUCTS LOOK ON TRACK THIS MORNING...BUT MIGHT
NEED TO TWEAK HOURLY GRIDS. LOOKING AHEAD...SEEING A TREND IN THE
MODELS TO SLOW DOWN THE EASTWARD SPREAD OF PRECIPITATION SATURDAY
NIGHT. MAY ADJUST POPS DOWN SOME FOR SATURDAY NIGHT AFTER VIEWING
12Z MODEL RUNS.
