AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
130 AM EDT MON APR 6 2009

.SYNOPSIS...
SURFACE HIGH PRESSURE WILL MOVE OFF THE SOUTHEAST COAST TODAY AS
LOW PRESSURE LIFTS NORTHEAST INTO NEW ENGLAND. SHOWERS AND
THUNDERSTORMS IN ADVANCE OF A STRONG COLD FRONT EXTENDING SOUTH
FROM THE LOW WILL SPREAD INTO THE MID ATLANTIC REGION THIS MORNING.
MUCH COLDER WEATHER WILL ARRIVE TODAY AS THE FRONT PASSES TO THE
EAST...TO BE FOLLOWED BY MOUNTAIN SNOW SHOWERS WHICH MAY PERSIST
INTO WEDNESDAY. MODERATING TEMPERATURES...ALONG WITH ANOTHER
THREAT OF PRECIPITATION...ARE EXPECTED BY THE END OF THE WEEK.

&&

.NEAR TERM /THROUGH TODAY/...
UPSTREAM RADARS SHOW A WELL ORGANIZED LINE OF TSTMS JUST AHEAD OF
THE SFC COLD FRONT ACROSS KY AND TN. A SEVERE THUNDERSTORM WATCH
EXTENDS RIGHT UP TO THE WESTERN BORDER OF THE CWA. AS THE STORMS
MOVE INTO THE CWA AROUND 07 TO 08Z...THE LOWER LEVELS WILL BE
MORE STABLE...AND THE STORMS SHOULD BE WEAKENING. HOWEVER...THERE
WILL STILL BE PLENTY OF UPPER LEVEL LIFT WITH THE LEFT EXIT REGION
OF A STRONG JET MOVG ACROSS THE CENTRAL APPLNS. EVEN THOUGH THE
STORMS WILL LIKELY BE WEAKENING...THE LOW LEVEL JET IS STRONG
ENOUGH THAT WITH EVEN WEAK MOMENTUM TRANSFER THEY COULD STILL
HAVE SOME STRONG GUSTY WINDS. I HAVE ADJUSTED THE TIMING OF THE
POPS OVERNIGHT...AND IN THE WESTERN SECTIONS OF THE CWA I HAVE
ADDED IN GUSTY WINDS TO THE TSTMS. I MADE SOME ADJUSTMENTS TO THE
CURRENT TEMPS...WHICH ARE RUNNING MUCH WARMER THAN FCST AND
RESULTED IN SLIGHTLY WARMER OVERNIGHT LOWS IN THE EAST. THE FRONT
ITSELF STILL LOOKS TO PASS THROUGH THE REGION BETWEEN ROUGHLY 500
AM IN THE BLUEFIELD WEST VIRGINIA REGION...BUT MAY TAKE TILL 900
AM OR 1000 AM IN THE DANVILLE VIRGINIA AREA.

A DRY SLOT WILL MOVE IN BEHIND FRONT BY MID-DAY...HELPING TO SHUNT
PRECIPITATION AND MUCH OF THE CLOUD COVER EAST OF THE BLUE RIDGE OUT
OF THE AREA. IN THE MOUNTAINS...UPSLOPE FLOW WILL DEVELOP AS WINDS
BECOME MORE WESTERLY AND THEN NORTHWEST. GUSTY CONDITIONS WILL EXIST
WITH 30 TO 40 MPH LIKELY IN THE MOUNTAINS AND 20 TO 30 MPH WEST OF
THE BLUE RIDGE BY THE AFTERNOON. TEMPERATURES THROUGH THE DAY WILL
BE FALLING. HIGH TEMPERATURES OF THE UPPER 40S IN THE WEST AND UPPER
60S IN THE EAST WILL BE REALIZED AROUND SUNRISE. BY THE
AFTERNOON...WE ARE EXPECTING TEMPERATURES TO BE IN THE MID TO UPPER
30S WEST...MID 50S FAR EAST. ENOUGH COLD AIR WILL MAKE IT INTO
WESTERN AND HIGHER PORTIONS OF THE REGION FOR A MIX OR CHANGE TO
LIGHT SNOW. LITTLE IN THE WAY OF ACCUMULATION IS EXPECTED GIVEN HOW
MUCH RELATIVELY WARMER THE GROUND WILL BE.

&&

.SHORT TERM /TONIGHT THROUGH WEDNESDAY/...
AS A STRONG COLD FRONT MOVES EAST OF THE AREA MONDAY EVENING...COLD
AIR WILL FILTER INTO THE REGION WITH SNOW SHOWERS DEVELOPING ACROSS
THE MOUNTAINS. DESPITE GOOD MOISTURE ADVECTION IN COLD NORTHWEST
FLOW...ACCUMULATIONS WILL BE LIGHT DURING THE EVENING AS GROUND
REMAINS WARM. AFTER MIDNIGHT...ACCUMULATIONS ARE LIKELY IN THE HIGHER
ELEVATIONS OF SOUTHEAST WEST VIRGINIA WITH A POSSIBLE COATING ON
VEGETATION AND ELEVATED SURFACE IN THE LOWER ELEVATIONS. MOUNTAIN
SNOW SHOWERS SHOULD CONTINUE INTO THE DAY TUESDAY. THE MORE INTENSE
SNOW SHOWERS WILL BE HIT AND MISS THROUGH THE DAY WHILE FLURRIES
PERSIST. ACCUMULATIONS WILL BE A TOUGH CALL AS INTENSE SNOW BAND MAY
DROP A HALF TO AND INCH OF SNOW IN A BRIEF TIME. ONCE SNOW STOPS
OVER AN AREA...INSOLATION WILL MELT THE NEWLY FALLEN SNOW DESPITE
OVERCAST SKIES. WOULD NOT BE SURPRISED TO SEE LIGHT RAIN SHOWERS AND
A FEW SNOW FLAKES EAST OF THE BLUE AS SHORT WAVE DIGS SOUTH ACROSS
THE CAROLINAS AND MOUNTAIN WAVES FORMS DURING THE MORNING. AREAS
EAST WILL DEFINITELY HAVE WARMER GROUND THAN THE MOUNTAINS AND NO
ACCUMULATIONS ARE EXPECTED. UPSLOPE SNOW SHOWERS TO CONTINUE INTO
TUESDAY NIGHT AS THE LAST OF THE STRONG SHORT WAVES EXITS THE EAST
COAST. HOWEVER...TRAJECTORIES WEAKEN OR ARE LOST FROM THE GREAT
LAKES. WEDNESDAY...ANOTHER SHORT WAVE...HOWEVER WEAKER..TRACKS
ACROSS THE OHIO VALLEY AND TAPS SOME WARM MOIST AIR. THIS MAY BRING
LIGHT ADDITIONAL ACCUMULATIONS TO WESTERN SLOPES BUT THE BOUNDARY LAYER
WILL BE WARM ENOUGH TO HAVE MOST PRECIPITATION FALLING AS RAIN.

IN THE WAKE OF THE COLD FRONT...PRESSURE RISES WILL BRING
BREEZY/GUSTY CONDITIONS TO THE REGION. 12Z MODELS NOT DISPLAYING AN
SIGNIFICANT LOW LEVEL JET OR VERY STRONG COLD AIR ADVECTION. NOT
FORESEEING ANY HEADLINES AT THIS TIME...BUT WILL CONTINUE TO
HIGHLIGHT IN HWO.

TEMPERATURES DURING THE PERIOD WILL RUN ABOUT 15F BELOW NORMAL.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
HEIGHTS ARE EXPECTED TO RISE WEDNESDAY NIGHT WITH ZONAL FLOW ON
THURSDAY. A WARM FRONT WILL MOVE ACROSS THE AREA WITH LIGHT RAIN
SHOWERS/SPRINKLES ACROSS THE GREENBRIER VALLEY LATE AFTERNOON AND
THURSDAY EVENING. PREFRONTAL SHOWERS TO ENTER THE WEST SHORTLY AFTER
SUNRISE FRIDAY SPREADING TO THE EAST DURING THE AFTERNOON. ANOTHER
ROUND OF SHOWERS IS EXPECTED WITH THE COLD FRONT LATE FRIDAY
AFTERNOON AND EVENING. IF ENOUGH SUN POKES THROUGH THE CLOUDS DURING
THE DAY...AND ISOLATED RUMBLE OF THUNDER IS POSSIBLE. NOT MUCH COLD
AIR IS BEHIND THIS SYSTEM BUT IF ENOUGH MOISTURE IS AROUND FRIDAY
NIGHT...A FEW SNOW SHOWERS ARE POSSIBLE ALONG THE HIGHER RIDGES OF
SOUTHEAST WEST VIRGINIA. ON SATURDAY...A CHILLY NORTHERLY WIND WILL
BRING TEMPERATURES BELOW NORMAL THROUGH THE WEEKEND AS HIGH PRESSURE
WEDGES DOWN THE EAST COAST.

TEMPERATURES WILL MODERATE BACK TO NORMAL THURSDAY AND FRIDAY...THEN
DROP BELOW NORMAL FOR NEXT WEEKEND.

&&

.AVIATION /06Z MONDAY THROUGH FRIDAY/...
CHECK AIRMETS AND SIGMETS THIS MORNING FOR TURBULENCE...ICING AND
MOUNTAIN OBSCURATIONS WITH COLD FRONT MOVING ACROSS REGION.

VFR CONDITIONS WILL LOWER TO MVFR CONDITIONS IN CLOUDS AND
CONVECTION THIS MORNING. A SURFACE COLD FRONT WILL PASS ACROSS THE
AREA BETWEEN ROUGHLY 08Z IN THE WEST TO 15Z IN THE EAST MONDAY
MORNING. ACCOMPANYING THIS FRONT WILL BE SOME HEAVIER RAIN SHOWERS
AND POTENTIALLY SOME ISOLATED THUNDERSTORMS.

VSBYS/CIGS DURING THE TIME OF THE FRONTAL PASSAGE WILL BE MVFR OR
VFR FOR THE MOST PART...WITH SOME TEMPORARY IFR CONDITIONS DUE TO
LOCALIZED VERY HEAVY RAIN. BEHIND THE FRONT WINDS WILL VEER WEST TO
NORTHWEST AND BECOME GUSTY. SURFACE GUSTS BY LATE THIS MORNING WILL
BE AROUND 30 TO 35KTS AT HIGHER ELEVATIONS. CIGS/VSBYS WILL LIFT TO
VFR AFTER FROPA. SOME UPSLOPE RAIN SHOWERS WILL DEVELOP BY THE LATE
MORNING IN THE MTNS...BRINGING MVFR CONDITIONS BACK INTO BLF AND
LWB. BY 21Z MONDAY...NUMEROUS RAIN AND SNOW SHOWERS WILL BE MOVING
INTO THE MTNS...BRINGING IFR TO MVFR CONDITIONS TO BLF AND LWB.

UPSLOPE SNOW SHOWERS WILL CONTINUE IN THE MOUNTAINS THROUGH
TUESDAY NIGHT. MVFR CONDITIONS ARE LIKELY AT BLF AND LWB...ALONG
WITH PERIODS OF IFR AT BLF.

VFR CONDITIONS RETURN BRIEFLY TO THE ENTIRE REGION ON THURSDAY
BEFORE OUR NEXT WEATHER SYSTEM ENTERS THE AREA ON FRIDAY. SHOWERS
AND THUNDERSTORMS WILL RETURN TO THE AREA AS ANOTHER COLD FRONT
MOVES THROUGH.
