AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
402 AM EDT TUE APR 15 2008

.SYNOPSIS...
HIGH PRESSURE WILL BUILD INTO THE AREA TODAY AND WEDNESDAY....THEN
REMAIN OVER THE REGION INTO FRIDAY. THERE WILL BE A MODERATION OF
TEMPERATURES BEGINNING WEDNESDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
CLOUDS ARE RAPIDLY ERODING ACROSS THE FORECAST AREA EARLY THIS
MORNING AS MUCH DRIER AIR MOVES IN ON NORTHERLY FLOW. TEMPS HAVE
BEEN SLOW TO DROP EAST OF THE MTNS OVERNIGHT. STILL LOOKS LIKE WE
MAY APPROACH FREEZING THOUGH AND TEMPS WILL AT LEAST DROP INTO THE
33 TO 36 DEGREE RANGE...SO THE FREEZE WARNING/FROST ADVISORY IN
EFFECT FOR THIS MORNING TILL 900 AM WILL BE LEFT UP.

HIGH PRESSURE WILL BE BUILDING INTO THE AREA TODAY AND MODELS
CONTINUE TO HAVE IT DIRECTLY OVER THE FCST AREA BY WED MORNING.
MODEL SOUNDINGS SHOW A VERY DRY AIRMASS...SO I HAVE LOWERED SKY
COVER DOWN CLOSE TO ZERO BY LATE AFTERNOON. STILL SHOULD BE VERY
GOOD RADIATION CONDS TONIGHT...ESPECIALLY IN THE MTNS. FROST
FORMATION MAY BE TOUGH- ESPECIALLY IN THE PIEDMONT...WITH SUCH A
DRY AIRMASS IN PLACE. IT LOOKS LIKE THE DEWPOINT DEPRESSION MAY
BE 5 DEGREES OR MORE EVEN TOWARD MORNING. I HAVE ADJUSTED THE
FROST SOME IN THE WEATHER GRIDS TO BEGIN LATER. IN ANY EVENT...I
EXPECT LOW TEMPS TO BE AT OR BELOW FREEZING FOR ALL OR NEARLY ALL
OF THE FORECAST AREA. I WILL ISSUE A FREEZE WARNING FOR ALL
OF OUR FOOTHILL AND PIEDMONT COUNTIES WHERE THE GROWING SEASON HAS
BEGUN. WILL BE A HARD FREEZE IN THE MTNS WHERE LOWS SHOULD DROP
WELL INTO THE 20S...BUT NO FREEZE WARNING THERE AS THE GROWING
SEASON HAS NOT OFFICIALLY BEGUN.

&&

.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/...
WITH THE SFC HIGH PRESSURE PARKED OVER THE CWA ON WED...AND MODELS
SHOWING NE WINDS AT LEAST IN THE PIEDMONT...HIGH SWILL END UP
BEING FAIRLY UNIFORM. WARM ADVECTION IN THE FAR WEST WILL PROBABLY
MAKE SMYTH/TAZEWELL AND MERCER COUNTIES THE WARMEST SPOTS...WHILE
LYNCHBURG AND EASTWARD MAY BE THE COOLEST. I HAVE LOWERED HIGHS
BELOW GUIDANCE EAST OF THE MTNS...AND RAISED A LITTLE ABOVE
GUIDANCE WEST OF THE MTNS. WITH THE DRY AIR IN PLACE...WILL BE A
HUGE DIURNAL SWING IN TEMPS BOTH WED AND THU. STILL UNDER THE
INFLUENCE OF HIGH PRS OVER THE REGION WED NIGHT AND DESPITE
STRENGTHENING BOUNDARY LAYER WINDS...MOST AREAS WILL DECOUPLE. SO
I HAVE LOWERED THE LOW TEMPS WED NIGHT MOST LOCATIONS. MAY END UP
NEEDING A FROST ADVISORY FOR WED NIGHT IN THE EAST.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
THE UPPER PATTERN TRANSFORMS INTO RIDGING THURSDAY. THERE IS SOME
UNCERTAINTY ABOUT HOW MUCH INFLUENCE THE LOW PRESSURE IN THE
WESTERN ATLANTIC WILL HAVE ON THE AREA THURSDAY. IT MAY KEEP MORE
OF A NORTHERLY FLOW IN THE PIEDMONT WHICH WOULD HOLD HIGH TEMPS
DOWN. HOWEVER...THE GENERAL TREND WILL BE FOR MODERATING
TEMPERATURES TO ABOVE NORMAL LEVELS. AT LEAST BY FRIDAY...A
SOUTHWESTERLY FLOW WILL BRING A STRONG REBOUND OF TEMPS TO ABOVE
NORMAL LEVELS EVEN IN THE PIEDMONT.

BEYOND FRIDAY MODELS CONTINUE TO DISAGREE ON THE EXTENT OF THE
UPPER PATTERN AMPLIFICATION. HAVE NOT MADE ANY CHANGES BEYOND FRI
NIGHT TO THE EARLIER FCST WHICH WAS BASED ON AN HPC SOLUTION
WHICH IS A BLEND OF THE 12Z GFS FROM APRIL 13TH AND ECWMF
ENSEMBLES. STILL LOOKS LIKE A FRONTAL SYSTEM ARRIVES
SATURDAY....BUT WITH A CLOSED UPPER LOW MOVING INTO THE SOUTHEAST
RIDGE...THE FNT WILL BE SLOWLY MOVING THROUGH THE AREA AND MAY
EVEN STALL...SO LOOKING AT A CHANCE OF SHOWERS FOR THE WHOLE
WEEKEND INTO MONDAY.

&&

.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
UPPER LEVEL TROUGH AND ASSOCIATED LIGHT PRECIPITATION MOVING SOUTH
OF THE AREA EARLY THIS MORNING. ALSO THROUGH SUNRISE...SKIES WILL
BECOME CLEAR FROM NORTH TO SOUTH WITH VFR CONDITIONS ANTICIPATED
THROUGH THE PERIOD. GOOD RADIATIONAL COOLING CONDITIONS THIS
MORNING AND WEDNESDAY MORNING WILL LEAD TO FROST FORMING ACROSS THE
ENTIRE AREA.

THE NEXT COLD FRONT TO INFLUENCE THE TERMINAL AREA WILL BE PASSING
THROUGH THE REGION THIS WEEKEND. THIS MAY BRING SHOWERS WITH MVFR
OR OCCASIONAL IFR CONDITIONS AT ALL AIRPORTS ON SATURDAY.
