AREA FORECAST DISCUSSION...CORRECTED TO ADD FFA
NATIONAL WEATHER SERVICE BLACKSBURG, VA
230 PM EDT SAT SEP 27 2003

SHORT TERM...
FRONT SLOWER THAN PREVIOUSLY PROGGED AND WILL TAKE MUCH OF THE NIGHT
TO CROSS THE ENTIRE CWA.  AHEAD OF THE FRONT SHRA/TSRA LIKELY FROM
THE FOOHTILLS WESTWARD WITH OCCURRENCE DURING FAVORABLE TIME OF
DAY.  EXPECTING AT LEAST SCATTERED CONVECTION TO CONTINUE INTO THE
PIEDMONT THIS EVENING...BUT SHOULD BE WEAKENING IN INTENSITY AND
COVERAGE WITH LOSS OF DAYTIME HEATING. WILL CONT THE FFA FOR
ROCKBRIDGE AND AMHERST COUNTIES THROUGH MIDNIGHT WHERE FFG OF 1.5 IN
AN HOUR AND RECENT FLOODING MAKES THEM SUSCEPTIBLE.

SUNDAY STRONG CAA TAKING PLACE WITH INCREASING LOW LEVEL MOISTURE
INTO THE WESTERN UPSLOPE COUNTIES.  HAVE REINTRODUCED CHC SHOWERS IN
FAVORED LOCATIONS FOR THE AFTERNOON.  EXPECTING A VERY WIDE RANGE IN
TEMPS WITH 50S IN THE WEST WITH CLOUDS TO 70S IN THE EAST WITH
STRONG DOWNSLOPING AND SUNSHINE.
SPN

LONGER TERM...
STRONG CAA CONTINUES INTO SUN NIGHT. GFS IS A LITTLE WARMER...AND
ETA  A LITTLE COLDER...THAN MODEL RUNS YESTERDAY. BOTH BRING AROUND
ZERO AT 850 MBS INTO THE MTNS...WITH PLENTY OF LL MOISTURE.
HOWEVER...LL WINDS ARE MORE WESTERLY LATE SUN NIGHT- NOT THE BEST
UPSLOPE. DECIDED TO EXTEND THE SLIGHT CHC RW- THRU THE NIGHT IN
UPLSOPE AREAS THOUGH. MOS LOWS FROM THE UPPER 30S MTNS TO M-U 40S
PIEDMONT LOOK GOOD. LOOKS LIKE CLOUDS WILL HANG ON IN UPSLOPE AREAS
THRU THE DAY MONDAY...AND WITH THE FAIRLY STRONG CAA...MAX TEMPS HAD
TO BE LOWERED. HIGHS MONDAY WILL BE ABOUT 15 DEGS BELOW NORMAL.

HIGH PRS BUILDS INTO THE SRN APPLNS TOWARD TUE MORN. LOOKS NOW LIKE
THE TIMING WILL NOT PROVIDE VERY GOOD RADIATION CONDS...SO LESS OF A
THREAT OF FROST/FREEZE. HAVE KEPT LOWS ABOUT THE SAME IN THE MTNS-
MID 30S MOST AREAS.

TIMING OF NEXT FNT IS A LITTLE SLOWER...BUT THE GFS SHOWS AN AREA OF
LIGHT PCPN AHEAD OF A DIGGING VORT MAX AND THE BULK OF THIS PCPN IN
THE MTNS LATE TUE NIGHT/WED MORN. ONCE AGAIN...STRONG CAA BEHIND
THIS FNT WED NIGHT INTO THU. HAVE DISCOUNTED THE GFS 850 MB TEMPS OF
-6C IN THE WV MTNS...BUT DID LOWERE TEMPS CONSIDERABLY.
