A fast-moving Alberta Clipper brought snow showers and gusty winds to the Allegheny Front and Potomac Highlands of the eastern pan handle of West Virginia by 10:00 AM on January 9 through 9:00 AM on January 10. While average snowfall reports with this system ranged from 1 to 4 inches, a Cooperative Observer in Bayard, WV, reported 7 inches of snow by 6:00 AM on January 10.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
410 AM EST TUE JAN 9 2006
.SHORT TERM (TONIGHT THROUGH TUESDAY)...
WATER VAPOR LOOP SHOWS A LONG WAVE TROUGH ACROSS THE NORTH CENTRAL
CONUS...WITH EMBEDDED WAVES MOVING EAST ACROSS THE TENNESSEE VALLEY
AND SOUTHEAST ACROSS THE MIDWEST. ACARS 400-250MB WIND OBSERVATIONS
REVEAL 140-180KT WINDS ROUND THE AFOREMENTIONED TROUGH. 04Z SURFACE
ANALYSIS PLACED A TROUGH IN THE LEE OF THE APPALACHIANS. A COLD
FRONT WAS CROSSING CHICAGO AND SAINT LOUIS...WITH A SECOND TRAILING
COLD FRONT SINKING SOUTH THROUGH THE UPPER MIDWEST.
A CLEAR START TO THE DAY WILL QUICKLY DETERIORATE WITH THE APPROACH
OF A STRONG SHORTWAVE. THE VERTICAL MOTION COUPLET OF THE WAVE
ACROSS SOUTHERN ILLINOIS HAS BEEN INCREASINGLY MORE IMPRESSIVE
THROUGH THE NIGHT ON WATER VAPOR IMAGERY. GFS/NAM IN AGREEMENT THAT
THIS WAVE FEEDING INTO THE LONGWAVE TROUGH WILL ALLOW THE TROUGH TO
BECOME NEGATIVE TILTED BEGINNING LATE TODAY...CAUSING SIGNIFICANT
CYCLOGENESIS OFFSHORE TONIGHT. DEEP LAYER LAPSE RATES BETWEEN 1000MB
AND 500MB ARE FORECAST TO BE STEEP...NEAR 7.5C/KM. GIVEN THE
SYNOPTIC SITUATION...AM CONCERNED THAT VERTICAL MOTION CAUSED BY THE
SHORT WAVE LATE THIS AFTERNOON MAY BE ENOUGH TO ALLOW A 1-2 HOUR
SNOW SHOWER BURST. WITH TEMPERATURES REACHING INTO THE MID 40S...NO
ACCUMULATION IS EXPECTED EAST OF THE MOUNTAINS...HOWEVER THERE MAY
BE A SOCIETAL IMPACT WITH THE FIRST POSSIBILITY OF FLAKES ACROSS THE
GREATER WASHINGTON METRO AREA (CLOSE TO EVENING RUSH HOUR).
OF COURSE THERE WILL BE A CHALLENGE TO SEE SNOW FLAKES THIS
AFTERNOON AFTER HIGHS IN THE MID 40S (A BIT COOLER THAN MOS GIVEN
RAPID INCREASE IN CLOUDS EXPECTED THIS MORNING). 0C HEIGHT IS JUST
OFF THE SURFACE AT 2KFT. DRY AIRMASS (PRECIPITABLE WATER VALUE OF
0.19 AT 00Z KIAD RAOB) WILL ALLOW EVAPOARATIONAL COOLING. DYNAMICAL
COOLING MAY BE A SIGNIFICANT FACTOR WITH IMPRESSIVE VERTICAL MOTION
SHOWN BY THE NAM DURING THE LATE AFTERNOON. THIS VERTICAL MOTION IS
WITHIN THE DENDRITIC SNOW GROWTH RANGE...WHICH WOULD FAVOR LARGE
DENDRITE FORMATION WITHIN THE CLOUD LAYER (WITH A SHORT TRIP WITHIN
THE WARM SUB-CLOUD LAYER TO THE GROUND). THERE IS ALSO INDICATION OF
FRONTOGENESIS IN THE 700-850MB LAYER AS THE SYSTEM BEGINS TO
DEEPEN...WHICH WOULD SUPPORT PRECIPITATION DEVELOPMENT EAST OF THE
MOUNTAINS.
THERE IS LESS UNCERTAINTY ALONG THE WESTERN SLOPES OF THE MOUNTAINS
WHERE TEMPERATURES ARE ALREADY SUPPORTIVE OF SNOW...AND IN FACT SNOW
HAS ALREADY BEEN REPORTED AT KEKN AS OF 09Z. BEHIND THE WARM
ADVECTION AND LEADING EDGE OF THE COLD ADVECTION
PRECIPITATION...UPSLOPE SNOW WILL PERSIST THROUGH THE NIGHT...AS THE
SKY EAST OF THE MOUNTAINS BECOMES MOSTLY CLEAR TO PARTLY CLOUDY.
HAVE ISSUED A SNOW ADVISORY WITH 03Z SHORT RANGE ENSEMBLES AT KEKN
INDICATING A MEAN OF 0.37" OF SNOW LIQUID EQUIVALENT THROUGH 12Z
EARLY WEDNESDAY MORNING...AND A MAX OF 0.85". CURRENT SNOW FORECAST
IN THE MOUNTAINS IS 1-3" TODAY AND 1-2" TONIGHT. WIND GUSTS OF 35
MPH ACROSS THE REGION TONIGHT WILL ALLOW WIND CHILLS TO NEAR ZERO
ACROSS THE HIGHER TERRAIN LATE TONIGHT.
&&
.AVIATION...
STRONG WAVE WILL ALLOW UPPER TROUGH TO GO NEGATIVE TILT BEGINNING
LATE THIS AFTERNOON. MID LEVEL CLOUDS WILL MOVE IN DURING THE
MORNING. THERE COULD BE A BRIEF SHOT OF IFR CLOUDS/VISIBILITIES WITH
RAIN/SNOW SHOWERS ASSOCIATED WITH THE LEADING EDGE OF THE COLD
ADVECTION. NORTHWEST DOWNSLOPE FLOW WILL DEVELOP BY EVENING AND
ALLOW MUCH OF THE CLOUDS TO DISSIPATE.
&&
.MARINE...
00Z GFS/ETA MOS AT THOMAS POINT BOTH SUGGEST SUSTAINED WINDS WILL BE
IN THE 10-15KT RANGE TODAY...AND 15-20KT RANGE TONIGHT. 00Z NAM
PROXIMITY LAND BUFKIT FORECAST SOUNDINGS SUGGEST ADDITIONAL WIND
GUST MOMENTUM OF 20 KNOTS BETWEEN 14-20Z...WHILE THE 00Z GFS
INDICATES GUSTS BETWEEN 18-22 KNOTS. BOTH THE 00Z NAM AND GFS
INDICATE 30KT WIND GUSTS THIS EVENING AND TONIGHT BEHIND THE COLD
FRONT. SINCE THE LULL IS ONLY SEVERAL HOURS...WILL HAVE ONE SMALL
CRAFT ADVISORY BEGINNING AT 14Z TODAY.
IN NW FLOW STRONG SCA WINDS ARE LIKELY TO CONTINUE ON WED. HAVE
EXTENDED THE PREVIOUSLY ISSUED SCA INTO WEDNESDAY. WINDS WILL
QUICKLY DIMINISH WED EVNG AS HIGH MOVES INTO THE MID ATLC.

.TIDES...
WATER LEVELS ARE CURRENTLY A QUARTER FOOT BELOW ASTRONOMIC
PREDICTIONS. THE LUNAR CYCLE IS WANING FROM A FULL MOON (71% FULL).
BLOWOUT CONDITIONS WERE EXPERIENCED YESTERDAY BEHIND THE COLD FRONT.
THE CHESAPEAKE BAY OPERATIONAL FORECAST SYSTEM FORECASTS WATER
LEVELS TO RECOVER TO PREDICTED LEVELS AGAIN TODAY...WHILE THE NOAA
EXTRATROPICAL STORM SURGE MODEL IS CURRENTLY OVER-FORECASTING WATER
LEVELS.

BEGINS TO BACK TO SW...THOUGH THE WARMING TREND WILL BE VERY SLOW
THROUGH THE END OF THE WEEK. SFC HIGH MOVES OFFSHORE BY FRIDAY AND
