Area forecast discussion, Jan 2, 3:55 AM EST, 24 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
355 AM EST SAT JAN 2 2010
.SYNOPSIS...
A VERY COLD NORTHWEST FLOW OF ARCTIC AIR WILL CONTINUE THROUGH
SUNDAY...AND THEN BEGIN SLOWLY MODERATING THE BEGINNING OF NEXT
WEEK. SEVERAL UPPER DISTURBANCES WILL SWING ACROSS THE REGION
THROUGH THE WEEKEND. THIS WILL CONTINUE TO BRING SNOW SHOWERS TO
THE MOUNTAINS INTO EARLY NEXT WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
WATER VAPOR SHOWS A SHORT WAVE ROTATING THROUGH THE OHIO VALLEY AT
THIS TIME. WESTERN SLOPE SNOW SHOWERS IN THE MTNS ARE
WIDESPREAD...EVEN INTO NRN NC. ONCE THIS SHORT WAVE MOVES INTO THE
CENTRAL APPLNS THIS MORNING...THE TRAJECTORIES BACK A LITTLE MORE
TO THE NW...AND THERE SHOULD BE LESS COVERAGE SOUTH OF THE
SOUTHEAST WV UPSLOPE AREAS. I HAVE LIKELY CATEGORICAL POPS ALL
UPSLOPE AREAS FIRST THING THIS MORNING...THEN BACK OFF ACROSS THE
SW VA MTNS AND NRN NC HEADING INTO THE AFTERNOON AND TONIGHT.
STILL LOOKS LIKE THERE WILL BE GENERALLY 1 TO 3 INCHES OF
ACCUMULATIONS FROM SMYTH COUNTY VA SOUTHWARD INTO THE NC MTNS...SO
DON/T THINK AN ADVISORY IS NEEDED THERE FOR THE SNOW. WILL
HOWEVER...HAVE WIND CHILL ADVISORIES...AND ALSO WIND ADVISORIES
FOR THOSE AREAS. FURTHER NORTH...WILL CONTINUE THE ADVISORY FOR
SNOW ACCUMS IN TAZEWELL WHERE A GOOD 3 TO 5 INCHES OF ACCUMS BY
SUNDAY MORNING ARE EXPECTED. WILL CONTINUE THE WINTER STORM
WARNINGS FOR UPSLOPE SE WV WHERE TOTAL ACCUMS OF 6 TO 12 INCHES ARE
STILL EXPECTED. HAVE EXPANDED THE WIND CHILL ADVISORIES THAT WERE
IN EFFECT UNTIL NOON TODAY TO INCLUDE THE ALLEGHANY HIGHLANDS OF
VA...SOUTHWARD T5O THE SW MTNS OF VA. WILL BE A VERY COLD DAY WITH
CONTINUOUS COLD ADVECTION ON STRONG NW WINDS. TEMPS ARE RUNNING
COLDER THAN GUIDANCE...WHICH USUALLY HAPPENS WITH ARCTIC AIR. HAVE
KEPT HIGHS TODAY LOWER THAN GUIDANCE...TEENS TO LOWER 20S IN THE
MTNS...AND MID 20S TO AROUND 30 EAST. FINALLY...WINDS ARE STRONG
ENOUGH THAT ADVISORY LEVEL GUSTS OF 45 TO 50 MPH WILL LIKELY OCCUR
IN THE HIGHER ELEVATIONS ALONG THE CREST OF THE APPLNS...SO WILL
ISSUE A WIND ADVISORY FOR THE ALLEGHANY HIGHLANDS OF VA...AND ALSO
THE MTN EMPIRE...AND THE NRN MTNS OF NC. WINDS REMAIN STRONG
TONIGHT...SO WILL HAVE THE WIND ADVISORY RUN THROUGH 600 AM
SUNDAY.
CONTINUED COLD ADVECTION TONIGHT...AND EVEN STRONGER WINDS...WILL
BRING WINDS CHILLS OF 5 TO 15 DEGREES BELOW ZERO FOR ALL OF THE
MTNS...SO WILL ISSUE A WIND CHILL ADVISORY FOR TONIGHT FOR ALL OF
THE MTNS. SINCE THIS ADVISORY WILL COVER ALL OF THE MTNS...WILL
ALSO INCLUDE THE 3 WV COUNTIES WITH A WINTER STORM
WARNING...RATHER THAN PUTTING THE LOW WIND CHILL INFORMATION IN
THE WARNING PRODUCT AS WE ARE DOING THIS MORNING. AGAIN...I
UNDERCUT GUIDANCE FOR THE LOWS TONIGHT BY A COUPLE OF DEGREES MOST
LOCATIONS.
&&
.SHORT TERM /SUNDAY THROUGH TUESDAY/...
THE UPPER LEVEL LOW OVER THE OHIO VALLEY TODAY...WILL MOVE OFF THE
NEW ENGLAND COAST AND MERGE WITH A SURFACE LOW. THIS SYSTEM WILL
BECOME A STRONG NOR-EASTER OFF THE NEW ENGLAND COAST INTO SUNDAY
NIGHT. THIS SYSTEM WILL DRIFT TO THE NORTHEAST THROUGH SUNDAY NIGHT
AND BEGIN TO LOSE ITS INFLUENCE ON THE AREA. ON MONDAY...AN UPPER
LEVEL TROUGH DRAPED FROM THE NEW ENGLAND COAST...INTO PENNSYLVANIA
AND BACK INTO THE GREAT LAKES WILL TRACK TO THE SOUTH AND OVER THE
AREA MONDAY NIGHT AND TUESDAY. DESPITE THE CONTINUED NORTHWEST
FLOW...THIS TROUGH SHOULD SLOW DOWN MOISTURE TRANSPORT FROM THE
GREAT LAKES AND REDUCE SNOW SHOWERS ENOUGH ON WESTERN SLOPES TO END
THE CURRENT WINTER STORM WARNING SUNDAY MORNING. THERE COULD STILL
BE SNOW SHOWERS THROUGH THE DAY SUNDAY ON WESTERN SLOPES BUT
ACCUMULATIONS WILL BE VERY LIGHT. MORE INTENSE SNOW SHOWERS WILL
RE-ENTER THE WEST WITH THE UPPER LEVEL TROUGH MONDAY NIGHT AND
TUESDAY. THE ASSOCIATED SHORT WAVES PIVOTING ACROSS THE AREA AND
NORTHWEST FLOW WILL HAVE MORE MOISTURE TO WORK WITH AND ANOTHER
LOCALIZED WINTER STORM WARNING IS POSSIBLE FOR SOUTHEAST WEST
VIRGINIA STARTING MONDAY NIGHT AND LINGERING INTO WEDNESDAY.
BLUSTERY CONDITIONS WILL CONTINUE INTO SUNDAY NIGHT AS MORE ARCTIC AIR
FILTERS INTO THE REGION. ON MONDAY...THE WINDS RELAX SOME WITH A
TEMPORARY BREAK FROM THE ARCTIC AIR SURGE. ONCE THE UPPER LEVEL TROUGH
SWINGS ACROSS THE AREA ON TUESDAY...ANOTHER COLD SURGE OF ARCTIC AIR
WILL PENETRATE THE REGION. TEMPERATURES MAY GET ABOVE FREEZING ACROSS
SOUTHSIDE ON MONDAY...BUT COME BACK DOWN ON TUESDAY. MOUNTAIN
TEMPERATURES WILL REMAIN VERY COLD AND IN THE UPPER TEENS TO MID
20S. OVERNIGHT LOWS ACROSS THE WEST WILL BE IN THE 5-15F RANGE
SUNDAY NIGHT AND 10-20F MONDAY NIGHT. WIND CHILL VALUES SUNDAY
MORNING WILL BE 5 TO 15 BELOW TO HAVE AN ADVISORY ACROSS THE WEST.
ANOTHER WIND CHILL ADVISORY IS POSSIBLE MONDAY MORNING ACROSS THE
ALLEGHANY HIGHLAND AND GREENBRIER COUNTY.
&&
.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
CLOSED LOW OVER NORTHEAST WILL SLOWLY EXIT TO THE NORTHEAST DURING
THE MEDIUM RANGE AS RIDGING CONTINUES IN THE WEST.
COLD NORTHWEST FLOW WILL CONTINUE INTO MID WEEK WITH SNOW SHOWERS
MAINLY CONFINED TO THE TYPICAL WESTERN SLOPES ESPECIALLY WHEN
SHORTWAVES ROTATE THROUGH THE REGION. MOISTURE IN THIS ARCTIC
AIRMASS REMAINS SHALLOW.
THE PATTERN FLATTENS AS HIGH PRESSURE RIDGES IN AROUND MIDWEEK.
AN AREA OF LOW PRESSURE WILL DEVELOP IN THE GULF WEDNESDAY NIGHT
AND LIFT NORTHEAST TO OFF THE VIRGINIA COAST BY 12Z FRIDAY.
HOWEVER...THERE WERE SOME DIFFERENCES IN MODEL SOLUTIONS WITH THE
SOUTHERN STREAM SYSTEM.
THE 00Z AND 12Z RUNS OF ECMWF SHOWED THE SURFACE LOW DEVELOPING
AND MOVING FROM THE GULF TO NEAR THE CAROLINA COAST FRIDAY-FRIDAY
NIGHT. PREVIOUS RUNS OF THE GFS HAVE ALSO SHOWN THIS
FEATURE...HOWEVER THE LATEST RUN BUILDS STRONG SURFACE HIGH PRESSURE
FURTHER SOUTH...THUS SUPPRESSING THE STORM TRACK WELL SOUTH OF THE
REGION. ANY STORM SYSTEM THAT DOES TRACK UP THE COAST COULD RESULT
IN SOME WINTRY PRECIPITATION.
&&
.AVIATION /09Z SATURDAY THROUGH WEDNESDAY/...
STRONG NORTHWEST FLOW WITH A SERIES OF UPPER DISTURBANCES WILL KEEP
AND MAINTAIN MVFR CIGS AT BLF/LWB WITH OCCASIONAL IFR IN HEAVIER
SNOW SHOWERS LATE TONIGHT INTO SATURDAY MORNING. THE LOWER
CLOUDS/CIGS WILL KEEP WINDS DOWN SOMEWHAT BUT EXPECT GUSTS TO
20-25 KNOT AROUND DAWN SAT.
FURTHER EAST...WITH THE STRONG NW FLOW...BKN/OCCASIONALLY OVC CIGS
WILL REMAIN BUT WILL BE VFR...ALTHOUGH POTENTIAL IS THERE FOR 3KFT
CIGS AT ROANOKE AND COULD SEE A FEW FLAKES OF SNOW TONIGHT-SATURDAY
MORNING. THE SIGNIFICANT THREAT WILL BE THE NW WINDS WHERE BY 12Z
SAT-18Z SAT...GUSTS TO 30-35 KNOTS ARE EXPECTED WITH A LITTLE LESS
IN DAN/LYH.
THE STRONG COLD AIR ADVECTION WITH LOW LEVEL TRAJECTORIES FROM OFF
LAKE MICHIGAN WILL RESULT IN A PROLONGED PERIOD OF UPSLOPE CLOUDS
AND SNOW SHOWERS WEST OF THE BLUE RIDGE...WITH MVFR TO
OCCASIONALLY IFR CONDITIONS AT BOTH KBLF AND KLWB BEYOND 18Z
SATURDAY...AND LASTING THROUGH AT LEAST SUNDAY. EAST OF THE
MTNS...THE MAIN AVIATION CONCERN WILL BE THE STRONG AND GUSTY NW
SFC WINDS.
THE NW FLOW PATTERN CONTINUES INTO NEXT WEEK...SO POTENTIAL FOR
SUB-VFR CIGS EXISTS AT BLF/LWB...WITH VFR ELSEWHERE.
