AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
1058 AM EST TUE NOV 25 2008
.SYNOPSIS...
MUCH COLDER AIR BEHIND A COLD FRONT WILL MOVE ACROSS THE AREA
THROUGH TONIGHT. AN UPPER LEVEL DISTURBANCE WILL ALSO PASS ACROSS
THE MOUNTAINS BY THIS AFTERNOON RESULTING IN INCREASING SNOW
SHOWERS AND GUSTY NORTHWEST WINDS. HIGH PRESSURE BUILDS IN FROM
THE WEST WEDNESDAY AND LINGERS SOUTH OF THE REGION INTO THURSDAY
&&
.NEAR TERM /THROUGH TONIGHT/...
RADAR NOW SHOWS A BACK EDGE TO THE AREA OF SNOW SHOWERS ASSOCIATED
WITH THE SHORT WAVE/VORT MAX MOVING ACROSS SW VA. THE BACK EDGE IS
MOVING THROUGH EXTREME EASTERN KY...AND WILL TRANSLATE EASTWARD
INTO THE CWA EARLY THIS AFTERNOON. LOOKS LIKE THERE WILL BE A
BREAK THEN THROUGH THE REST OF THE AFTERNOON FOR MOST OF THE
AREA...EXCEPT FOR WESTERN SLOPES IN SE WV- PARTICULARLY GREENBRIER
COUNTY. UPSLOPE SNOW SHOWERS SHOULD THEN GET GOING GOOD BY SUNSET.
THIS INITIAL AREA OF SNOW SHOWERS HAS BEEN HEAVIER THAN FORECAST
ACROSS TAZEWELL AND MERCER COUNTIES...WITH REPORTS OF 2 TO 3
INCHES ACCUMULATION COMMON. I HAVE RAISED SNOW TOTALS IN THOSE
COUNTIES...AND POSTED A NEW SNOW TOTAL MAP. WE CAN STILL GET BY
WITH AN ADVISORY...BUT IT WILL BE CLOSE TO WARNING LEVELS OVER 30
HOURS...WITH TOTALS OF 3 TO 6 INCHES. I ADJUSTED THE MAX TEMPS
DOWNWARD A FEW DEGREES IN THE MTNS...AND UPWARD A DEGREE OR TWO IN
THE PIEDMONT.
ACCUMULATING SNOW OVERNITE SHOULD BE CONFINED TO THE USUAL
NORTHWEST UPSLOPE AREAS...WITH GREENBRIER THEN GETTING THE
HEAVIEST SNOWS. WINDS WILL BE CLOSE TO ADVISORY LEVELS RIDGES
THIS EVENING NW NC WHERE THE BEST JET DEVELOPS SO BOOSTED
SPEEDS...BUT KEPT BELOW CRITERIA ATTM SINCE GOOD PRES RISES
LACKING. GOOD MIXING AND CLOUDS SHOULD KEEP THE MOUNTAINS FROM
BOTTOMING OUT OVERNIGHT WITH LOW/MID 20S LIKELY EXCEPT UPPER 20S
EAST.
&&
.SHORT TERM /WEDNESDAY THROUGH FRIDAY NIGHT/...
FINAL SHORT WAVE WITH MOISTURE TO PASS OVER THE AREA WEDNESDAY
MORNING. ADDITIONAL ACCUMULATIONS ARE POSSIBLE ON WESTERN SLOPES
OF SE WV...PARTICULARLY EXTREME WESTERN GREENBRIER THROUGH THE DAY
WEDNESDAY. PRESSURE GRADIENT REMAINS TIGHT AND WITH NORTHWEST FLOW
AND SUBSIDENCE...WINDY/GUSTY CONDITIONS WILL EXIST THROUGH EARLY
AFTERNOON. LATE IN THE DAY...SURFACE RIDGING EDGES INTO THE AREA
AND WINDS WILL DIMINISH THROUGH THE EVENING.
SURFACE HIGH PRESSURE WILL BE CENTERED OVER FLORIDA WEDNESDAY NIGHT.
WEAK SOUTHWESTERLY FLOW AND WARM AIR ADVECTION AROUND THIS HIGH WILL
KEEP RIDGE TEMPERATURES STEADY AND WARMER THAN THE VALLEYS...EVEN
WITH SNOW COVER. VALLEYS WILL DECOUPLE FIRST AND WITH GOOD
RADIATIONAL COOLING AND SNOW COVER...TEMPERATURES COULD BE 10F COOLER
THAN THE RIDGES...ESPECIALLY IN THE GREENBRIER VALLEY. HIGH PRESSURE
WILL SLIDE OFF TO THE EAST AND INCREASING SOUTHWESTERLY FLOW WILL
HAVE TEMPERATURES APPROACHING NORMAL ON THANKSGIVING.
&&
.LONG TERM /SATURDAY THROUGH MONDAY/...
SFC HIGH PRESSURE OVER THE SE CONUS SLIDES EAST INTO THE ATLANTIC
OCEAN FRIDAY...WHILE COMPLEX TROUGH DIGS INTO THE MID-MISSISSIPPI
VALLEY. THERE STILL REMAIN DIFFERENCES IN TIMING...PLACEMENT AND
MOVEMENT OF LOW CENTER AS IT TRACK THROUGH OUR REGION DURING THE
WEEKEND. THE ECMWF WAS SLOWER THAN GFS WITH THE SOUTHERN STREAM
SYSTEM. LEANED MEDIUM RANGE TOWARDS HPCGUIDE WHICH WAS PRIMARILY
DERIVED FROM THE ECMWF ENSEMBLE MEANS. MOISTURE RETURNS FRIDAY AS
FRONTAL WAVE MOVES OUT OF TENNESSEE AND PLAYED HIGHEST POPS IN THE
SOUTHWEST. THE COLD FRONT TRAVELS EAST OFF THE COAST SATURDAY
NIGHT...AND KEPT CHCY POPS IN THE MOUNTAINS. WITH WESTERLY FLOW
PLAYED HIGHEST POPS ON SUNDAY IN SOUTHEAST WEST VIRGINIA. ANOTHER
FRONTAL BOUNDARY EXPECTED ON MONDAY AND ADDED CHCY POPS TO THE
WESTERN MOUNTAINS.
&&
.AVIATION /16Z TUESDAY THROUGH SATURDAY/...
COLD FRONT HAS PUSHED EAST OF THE AREA ATTM WITH SKIES CLEARING
OVER THE EAST AND WRAP AROUND CLOUDS/-SHSN SPILLING BACK INTO THE
WEST AHEAD OF THE NEXT UPPER IMPULSE. THIS FEATURE WILL BRING AT
LEAST MVFR CIGS AND OCNL VSBYS IN -SHSN BACK TO SE WVA THIS
MORNING. ELSW EXPECTING VFR CONDITIONS ESLW WITH ONLY SOME
SPILLOVER OF STRATO-CU AND PERHAPS SOME -SHSN INTO KROA. NW WINDS
WILL BE STRONG THRU THE DAY BEHIND THE FRONT WITH GUSTS TO 25 KTS
OR GREATER AT TIMES.
DEEPER NW FLOW DEVELOPS LATER TODAY AND CONTINUES OVERNIGHT INTO
EARLY WEDNESDAY. THIS WILL RESULT IN PERIODIC MVFR/IFR CIGS/VSBYS
AT KBLF/KLWB IN LOW CLOUDS AND OCNL HEAVY SNOW SHOWERS THRU LATE
TONIGHT. HIGH PRESSURE SHOULD FINALLY BUILD IN ON THURSDAY WITH A
RETURN TO VFR CONDITIONS. ANOTHER STORM SYSTEM MAY BRING ANOTHER
