THE UPSLOPE SE WVA SITES SEEING LINGERING MVFR/VFR CEILINGS.

SHORT TERM /REST OF TODAY/...

INITIAL SHOT OF COLD AIR HAS MOVED ACROSS THE REGION THIS MORNING
WITH NEXT COLDER SURGE OF ARCTIC AIR STILL WEST OF THE OHIO
VALLEY. IN BETWEEN WILL SEE FLOW BACK A BIT THIS AFTERNOON WITH
SOME BRIEF 85H WARMING BEFORE THE NEXT FRONT ARRIVES THIS EVENING.
STILL SEEING A FEW FLURRIES ONGOING IN SPOTS FAR WEST...OTRW
EXPECT TO SEE LINGERING CLOUDS DIMINISH EARLY THIS AFTERNOON
BEFORE NEXT LOBE OF RH APPROACHES THE FAR NW LATE. THEREFORE WILL
LIKELY KEEP MENTION OF CLOUDS/FLURRIES MAINLY NW EARLY WITH SUNNY
SKIES ELSEWHERE UNDER WEAK RIDGE AXIS AND VERY DRY AIR. PLAN TO
ALSO KEEP GUSTY WESTERLY WINDS TO JUST BELOW ADVISORY LEVELS
RIDGES GIVEN JET ALOFT/MIXING. OTRW ADJUSTED TEMPS DOWN A LITTLE
BASED ON MORNING THICKNESS AND SOME SNOW COVER NW ZONES.

PREV DISCUSSION...
/ISSUED 647 AM EST SAT FEB 3 2007/

UPDATE...

AVIATION /12Z-12Z/...
VFR CONDITIONS CAN BE EXPECTED EAST OF THE MTNS. LCL MVFR
ANTICIPATED IN THE MTNS PER WIDELY SCT SHSN. LWB/BLF WILL
EXPERIENCE A PERIOD OF LOW CLOUDINESS AND FLURRIES THIS MORNING
FOLLOWED BY IMPROVED CONDITIONS THIS AFTERNOON. ANOTHER UPPER
LEVEL TROF WILL CROSS THE MTNS TONIGHT...BRINGING A RENEUED THREAT
OF MTN SNOW SHOWERS AND LOWERING CIGS. WINDS TODAY WILL BE OUT OF
THE WEST...AND GUSTY. GOOD MIXING TODAY WILL BRING GUSTS UP TO
25-30 KNOTS OVER THE HIGHER TERRAIN...SLIGHTLY LESS AT THE TAF
SITES.

PREV DISCUSSION...
/ISSUED 438 AM EST SAT FEB 3 2007/

SHORT TERM /TODAY/...
SCATTERED FLURRIES ONGOING ACROSS THE WESTERN CWA THIS MORNING.
ASIDE FROM THIS ACTIVITY...NOT MUCH HAPPENING. SAT IMAGERY SHOWS
SCT TO BKN CLOUD COVER FROM THE VA HIGHLANDS AND NEW RIVER VALLEY
WEST. CLEAR SKIES PREVAIL EAST OF THE MTNS.

FOR TODAY...ANTICIPATE FULL SUN EAST WITH SCATTERED CLOUDS WEST.
SFC HIGH PRESSURE COVERS THE SOUTHERN CONUS...FLOW AROUND THE HIGH
PROVIDING A DRY WEST WIND EAST OF THE MOUNTAINS. UPSLOPE
CLOUDINESS WILL CONTINUE IN THE WEST...ALONG WITH A FEW FLURRIES.

WINDS TODAY WILL BE A BIT GUSTY AT TIMES. THE WINDS AT ABOUT 5K
FEET ABOVE THE GROUND ARE FCST AROUND 40KTS. SOME OF THIS WIND
WILL LIKELY MIX DOWN TO THE SFC WITH RESULTANT GUSTS IN THE 25-30
KT RANGE. TEMPS WILL BE COLDEST IN THE MTNS...STRUGGLING TO CLIMB
OUT OF THE 20S. FULL SUN SHOULD ALLOW TEMPS TO CLIMB CLOSE TO 40
EAST OF THE MTNS.

LONG TERM /TONIGHT THROUGH FRIDAY/...
WAX UP YOUR SKIS. IDEAL SNOW MAKING CONDITIONS THIS UPCOMING WEEK.
IF YOU GO...PLAN FOR SOME BITTER WIND CHILLS.

A LARGE TROF OF LOW PRESSURE IS FCST TO REMAIN THE DOMINANT
WEATHER FEATURE IN THE UPPER LEVELS OF THE ATMOSPHERE THROUGH NEXT
WEEK. THE FLOW SFC/ALOFT WILL BE COMING FROM CANADA...A REGION
DOMINATED BY ARCTIC COLD. IT SEEMS A PIPELINE TO THE ARCTIC CIRCLE
HAS BEEN ESTABLISHED...AND THIS WILL RESULT IN SOME OF THE
COLDEST AIR OF THE SEASON TO BE CHANNELED SOUTHEASTWARD INTO THE
EASTERN CONUS.

TEMPS EARLY NEXT WEEK ARE EXPECTED TO BE WELL BELOW NORMAL...
AFTERNOON TEMPS STRUGGLING TO GET ABOVE 20 DEGREES IN THE
MOUNTAINS AND ABOVE 30 IN THE ERN CWA. WILL NEED AN EXTRA LOG ON
THE FIRE AT NIGHT...OVERNIGHT LOWS DIPPING TO NEAR ZERO IN THE
MOUNTAINS AND CLOSE TO 10 DEG F EAST OF THE MOUNTAINS. IN ADDITION
TO THE AMBIENT COLD...WILL ALSO HAVE TO DEAL WITH THE WIND. WIND
CHILLS OF MINUS 5 TO MINUS 15 ARE LIKELY IN THE MOUNTAINS FOR BOTH
MONDAY MORNING AND TUESDAY MORNING.

PRECIP POTENTIAL TONIGHT THROUGH NEXT WEEK LOOKS SCANT...UNLESS
YOU LIVE ON THE WESTERN SLOPES OF THE APPALACHIAN MOUNTAINS. AN
EXTENDED PERIOD OF WESTERLY UPSLOPE FLOW WILL RESULT IN A
CONTINUATION OF THE FLURRIES AND SCATTERED HEAVIER SNOW SHOWERS.
ITS NOT OUT OF THE QUESTION THE FAVORED UPSLOPE AREAS COULD
RECEIVE AN INCH OR TWO OF NEW SNOW EACH DAY FOR THE NEXT 3
DAYS... PLACES LIKE THE MOUNTAINS NW OF LWB...MT. ROGERS IN
VA...AND THE MTNS ALONG THE TN/NC BORDER. THE SNOW TO LIQUID RATIO
IS EXPECTED TO BE ABOUT 25:1 SO IT WONT TAKE MUCH LIQUID TO
GENERATE A MEASURABLE SNOW.
