AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
300 PM EDT TUE MAY 10 2005

.SHORT TERM...UPPER LEVEL SYSTEM WILL MOVE EAST OF AREA OVER THE
NEXT FEW HOURS...AND IT PRESENTS ONE OF THOSE TIMING PROBLEMS.  IT
WILL NOT BE RAINING EXCEPT FOR IN THE FAR NE PART OF OUR CWA COME 6
PM...BUT IT IS RAINING IN A LARGER AREA AT THIS TIME.  I DECIDED TO
STICK WITH THE CONCEPT OF A FORECAST...NOT A NOWCAST...AND GO WITH
THE WEATHER AS I EXPECT IT TO LOOK AT THE START OF THE TONIGHT
PERIOD.  AS SYSTEM MOVES AWAY, SHOULD SEE SOME CLEARING SKIES
TONIGHT...AND THAT WILL LEAD TO FOG FORMATION BY EARLY MORNING.
COULD BE FAIRLY LOW VSBYS FROM 10 TO 13Z...BUT EXPECT THAT ANYTHING
UNDER 1 MILE WILL BE VERY LOCALIZED.

CHANCE OF RAIN FOR TOMORROW NOW LOOKS VERY LOW AND DID NOT MENTION.
GUIDANCE TEMPS WERE REASONABLE AND WERE FOLLOWED CLOSELY.  WINDS
WILL BE VERY LIGHT NEXT 24 HOURS.  LOTS OF LOW LEVEL MOISTURE WILL
BE LEFT IN PLACE...AND THEREFORE OVERNIGHT LOWS WILL NOT BE AS LOW
AS THEY HAVE BEEN RECENTLY.

.LONG TERM...(WED NIGHT THROUGH TUE)...UPPER TROUGH/ASSOCIATED COLD
FRONT STILL PROJECTED TO PASS THROUGH THE SOUTHERN APPALACHIANS THIS
WEEKEND. HOWEVER...DISCREPANCIES IN TIMING BETWEEN MEDIUM RANGE
MODELS AND ENSEMBLES CAST DOUBT ON EXACT PROGRESSION OF THIS FEATURE
THROUGH THE FORECAST AREA. ECMWF IS CONSIDERABLY SLOWER THAN GFS
WITH THIS PROGRESSION. THE CANADIAN GEM AND NOGAPS TENDS TO SUPPORT
THE SLOWER ECMWF. THUS HAVE TENDED TO FAVOR ECMWF TIMING.
HOWEVER...HAVE EXPANDED PRECIP CHANCES THROUGH MUCH OF SATURDAY AND
SUNDAY DUE TO UNCERTAINTY. HAVE OPTED FOR DRY FORECAST FOR EARLY
NEXT WEEK...BUT AGAIN CONFIDENCE IS NOT HIGH.
