AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 230 PM EDT SAT JUL 31 2004 .SHORT TERM...(TONIGHT AND SUNDAY)...RADAR SHOWS BAND OF CONVECTION CURRENTLY MOVING THROUGH OUR FORECAST AREA IN ADVANCE OF A WEAKENING/FLATTENING UPPER TROUGH AND ASSOCIATED SURFACE COLD FRONT. MODELS AND ENSEMBLES GENERALLY AGREE THAT THIS BAND OF CONVECTION WILL CONTINUE TO SLOWLY MOVE EASTWARD TONIGHT AND BE MOSTLY EAST OF THE APPALACHIANS BY LATE IN THE FIRST PERIOD. GFS AND ENSEMBLES ARE MARGINALLY SLOWER WITH THE PROGRESSION THAN ETA WHICH CASTS SOME UNCERTAINTY ABOUT POPS IN THE SECOND PERIOD. INCLINATION IS TO FAVOR CONSENSUS AND CONTINUE CHANCE POPS EARLY IN THE SECOND PERIOD...AT LEAST FOR THE EASTERN ZONES. MODEL TIME HEIGHTS DEPICT CONSIDERABLE MID-LEVEL DRYING COMMENCING LATE IN THE FIRST PERIOD AND CONTINUING INTO THE SECOND PERIOD. HOWEVER...LOW LEVELS WILL REMAIN QUITE MOIST WHICH...COUPLED WITH MODERATE INSTABILITY AS PROJECTED BY FORECAST SOUNDINGS...SUGGESTS THAT ISOLATED TO SCATTERED DIURNAL CONVECTION CANNOT BE COMPLETELY RULED OUT.

SHOULD BE AN UPPER RIDGE TO OUR WEST AND AN EAST COAST TROUGH...BUT THINK THE 00Z GFS TOO AMPLIFIED. APPEARS ANOTHER WEAK FRONTAL BOUNDARY MAY COME DOWN SOMETIME AROUND WEDNESDAY...SO PLAN SLIGHT CHANCE POPS TUESDAY AFTERNOON THROUGH WEDNESDAY EVENING.
