AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
1255 AM EST SAT FEB 13 2010

.SYNOPSIS...
REDEVELOPMENT OF UPSLOPE SNOW SHOWERS SATURDAY WITH COLD NORTHWEST
FLOW...ESPECIALLY CENTRAL TO NORTHERN WV MOUNTAINS. SYSTEM WITH
AREAWIDE SNOW POSSIBLE SUNDAY NIGHT INTO MONDAY.

&&

.NEAR TERM /THROUGH TODAY/...
NO BIG CHANGES ON TEMPERATURES.  BASING FORECAST ON AXIS OF MID
LEVEL DISTURBANCE TO PASS 12Z TO 15Z SATURDAY. HAVE FLURRIES AND
SNOW SHOWERS INCREASING DURING THE PREDAWN SATURDAY THEN
CONCENTRATING OVER NRN WV AND THE WV MOUNTAINS BY AFTERNOON.  WOULD
NOT RULE OUT SOME MINIMUM ADVISORIES DUE TO THE FAVORABLE CRYSTAL
GROWTH TEMPERATURES.

HAVE POPS DECREASING A BIT FASTER DURING THE AFTERNOON OVER NE KY
AND SRN OHIO.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY/...
NORTHWEST FLOW SNOW SHOWER PATTERN WILL CONTINUE SATURDAY NIGHT
BEHIND DEPARTING CLIPPER.  HAVE ONLY A SLOW DROPOFF IN POPS DURING
THE NIGHT.  BUFKIT SOUNDINGS CONTINUE TO INDICATE MOISTURE IN THE
IDEAL SNOW GROWTH LAYER.  STILL...OVERALL MOISTURE DEPTH IS SHALLOW
AND EXPECT THIS WILL KEEP A DAMPER ON ADDITIONAL ACCUMULATION FOR
MOST LOCATIONS.  THE HIGHER RIDGES MAY SEE ANOTHER INCH OR TWO
OVERNIGHT...WHILE THE LOWLANDS WILL GET AN ADDITIONAL SPOTTY DUSTING
AT BEST.  BY 12Z...H850 TEMPS START MODERATING AND SNOW GROWTH LAYER
SHRINKS...SO COVERAGE WILL WANE SOMEWHAT.

ON SUNDAY...LINGERING LOW LEVEL MOISTURE AND WEAK H850 WARM
ADVECTION MAY CREATE SOME LIGHT OVERRUNNING SNOW ACROSS MAINLY THE
SOUTHWESTERN CWA.  DO INCREASE POPS A BIT FASTER THAN MODELS WOULD
SUGGEST WITH TYPICAL SLOW MODEL BIAS IN SUCH SITUATIONS.  IN ANY
CASE...ANY ACCUMULATION ON SUNDAY WILL BE VERY LIGHT...GENERALLY A
DUSTING TO A HALF INCH.

ATTENTION THEN TURNS TO POTENT H500 LOW WHICH SWINGS FROM THE MIDDLE
MISSISSIPPI VALLEY AT 00Z MON...TO A POSITION OVER THE TRI-STATE
AREA BY 00Z TUESDAY.  NAM/ECMWF AGREE ON A SLOWER SOLUTION...WITH
THE GFS SWINGING THE SYSTEM THROUGH FASTER.  GEM APPEARS TO BE THE
ODD MODEL OUT WITH A TRACK MUCH FURTHER SOUTH.  GOING WITH THE
NAM/ECMWF TIMING...WITH UNCERTAINTIES REMAINING.

THERE IS POTENT FORCING WITH THIS SYSTEM...WITH A MAXIMUM OF
H700/H850 FRONTOGENESIS AND H300 UPPER DIVERGENCE BETWEEN 12Z-18Z
MONDAY...RUNNING FROM THE COAL FIELDS NORTHEAST TO EKN. SURFACE LOW
REFLECTION FORMS ALONG THIS TRACK.  MOISTURE APPEARS TO BE A
LIMITING FACTOR.  PW VALUES TOP OUT AROUND .4 INCHES FOR A BRIEF
PERIOD AROUND 12Z MONDAY...AND GENERAL W/WSW FLOW WILL NOT BE ABLE
TO TAP THE GULF FOR MOISTURE BEFORE SYSTEM ARRIVAL. OTHER
IMPEDIMENTS TO ACCUMULATION WILL BE RELATIVELY HIGHER SNOW RATIOS
AND THE NOW-STRENGTHENING SUN ANGLE ALLOWING FOR SOME DAYTIME MELT.
STILL...FORCING POINTS TO DECENT SNOW RATES FOR A TIME PARTICULARLY
ON MONDAY.  AFTER AN INCREASE SUNDAY NIGHT...HAVE HIGH LIKELY/CAT
POPS ON MONDAY FOR THE MAJORITY OF THE CWA.  GENERAL SENSE RIGHT NOW
IS THAT THIS IS MORE OF AN ADVISORY EVENT RATHER THAN
WATCH/WARNING.  WILL MAINTAIN MENTION IN HWO.

GENERALLY BLENDED NEWER BIAS-CORRECTED MOSGUIDE GRIDS WITH PREVIOUS
TO COME UP WITH MAX/MIN TEMPERATURES.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS THE LOW MONDAY NIGHT PULLS OFF TO THE EAST...AREA TRANSITIONS
FROM SYNOPTIC SNOW TO AN UPSLOPE SNOW EVENT. GOOD DYNAMICS...SO
INCREASED POPS CONSIDERABLY. MODELS SNOW A PERSISTENT UPSLOPE
PATTERN FOR TUESDAY AND WEDNESDAY. MODELS THEN SHOW THE COLD PATTERN
HOLDING FOR THE END OF THE WEEK. WHILE THERE IS GOOD AGREEMENT ON
THE GENERAL COLD PATTERN...CONFIDENCE IN THE DETAILS AND TIMING OF
PRECIPITATION IMPULSES IS LOW.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
CLIPPER SYSTEM WILL BRING MVFR CIGS AND VSBYS ESPECIALLY TOWARD AND
FOLLOWING 12Z SAT.  CONDITIONS WILL IMPROVE AT LEAST AS FAR AS VSBYS
IN THE LOWLANDS SAT NT.

LIGHT W TO NW FLOW AT THE SFC WILL BE MODERATE ALOFT.

AFTER 06Z SUNDAY...
IFR LINGERING IN UPSLOPE SNOW SHOWERS IN WV MOUNTAIN COUNTIES
SATURDAY NIGHT. IFR POSSIBLE AREAWIDE IN SNOW SUNDAY NIGHT INTO
MONDAY NIGHT. IFR POSSIBLE TUESDAY AND TUESDAY NIGHT IN UPSLOPE
SNOW...MAINLY IN THE MOUNTAINS.

&&

.RLX WATCHES/WARNINGS/ADVISORIES...
WV...NONE.
OH...NONE.
KY...NONE.
VA...NONE.
