AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 235 PM EDT FRI AUG 24 2007 .SHORT TERM...(TONIGHT AND SATURDAY)...UPPER RIDGE CONTINUES TO FLATTEN OUT IN THE SHORT TERM...AND A WEAK COLD FRONT EDGES CLOSER. MODELS INDICATE A BETTER CHANCE OF PRECIP TOMORROW...AND MORE CLOUDS...WITH TEMPS LOWER THAN RECENT DAYS. AM NOT OPTIMISTIC FOR A DRAMATIC CHANGE...SO WILL ONLY GO WITH SLIGHT CHANCE POPS...AND WILL GENERALLY GO A BIT ABOVE MAV TEMPS BOTH TONIGHT AND TOMORROW. .LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)...FRONT CURRENTLY CAUSING CONVECTIVE ACTIVITY IN THE MIDWEST WILL TRY TO ASSERT ITSELF HERE ON SATURDAY NIGHT/SUNDAY, BUT CONFIDENCE IS LOW. GFS HAS A HUGE PRECIP BULLS EYE OVER THE CWA, BUT THIS APPEARS TO CONVECTIVE FEEDBACK, SO WILL PARTLY IGNORE. BELIEVE FRONT WILL DESTABILIZE AIR MASS ENOUGH TO RAISE POPS A HAIR, AND SOME SPOTS WILL RECEIVE BOUNTIFUL WELCOME RAIN, BUT IT WILL BE LARGELY A GOOSE EGG FOR MOST PLACES, AGAIN. UPPER RIDGE RETURNS TO DOMINANCE TUESDAY THROUGH THURSDAY, UNTIL THE NEXT POSSIBLE LITTLE SYSTEM MOVES THROUGH. THIS LATER TIME PERIOD IS REALLY THE PROBLEM BECAUSE MODELS SHOW A DRAMATIC PATTERN CHANGE WITH UPPER TROF SETTLING IN OVER EASTERN NOAM, AND RIDGE MOVING WEST. THIS WOULD PUT US IN MUCH COOLER TEMPERATURE REGIME. HOWEVER USUAL CAVEATS APPLY THIS FAR OUT. PLUS, WEVE ALL BEEN BURNED BEFORE WITH THIS TYPE OF ADVERTISED CHANGE DURING THE DEEPENING DROUGHT, SO I AM GUN SHY. HAVE LEFT TEMPS FROM PREVIOUS PACKAGE ALONE PRETTY MUCH. AT THIS POINT, COOLER MEANS JUST SEASONALLY HOT, NOT BLISTERING RECORDS. && .PRELIMINARY POINT TEMPS/POPS...
