AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
1210 PM EDT TUE MAY 3 2011

.SYNOPSIS...
A VERY SLOW MOVING COLD FRONT EXTENDED FROM NEW ENGLAND TO A LOW
OVER KENTUCKY...THEN INTO THE LOWER MISSISSIPPI VALLEY. THE LOW
WILL MOVE NORTHEAST INTO PENNSYLVANIA TODAY...WITH THE COLD FRONT
CROSSING THE MID ATLANTIC REGION THIS EVENING. HIGH PRESSURE WILL
BUILD IN BEHIND THE FRONT ON WEDNESDAY AND THURSDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
LOOKING LIKE THE BEST CONVERGENCE WILL BE ALONG THE BLUE RIDGE IN
FAR SW VA AND NW NC LATER IN THE AFTERNOON...WHILE MODELS STILL
BRING BETTER LIFT AHEAD OF THE FRONT IN THE FAR WEST LATE IN THE
AFTERNOON AS WELL. I HAVE UPDATED THE FORECAST TO PUT HIGHER POPS
ALONG THE BLUE RIDGE LATE IN THE AFTERNOON...THEN BLEND INTO THE
IDEA OF CATEGORICAL POPS BY EARLY EVENING FROM THE
FOOTHILLS...WESTWARD INTO THE MTNS. HAD TO ADJUST MAX TEMPS AS
WELL- LOTS OF SUN ACROSS THE NRN CWA HAS RESULTED IN WARMER
TEMPERATURES IN THE GREENBRIER VALLEY...ALLEGHANY HIGHLANDS AND
SRN SHEN VALLEY.

PREVIOUS DISCUSSION...
MORNING SATELLITE SHOWS A FAIRLY SOLID FIELD OF STRATUS ACROSS
THE PIEDMONT...WHILE THE MTNS HAVE AT LEAST PARTIAL SUNSHINE. MAIN
AFFECT THIS WILL HAVE ON TEMPS IS TO SLOW DOWN THE RISE IN THE
PIEDMONT- THINK THAT AFTERNOON SUN WILL STILL PRODUCE HIGHS IN THE
LOWER 80S IN THE PIEDMONT. HIGHS IN THE MTNS WILL BE A FEW DEGREES
WARMER...AND HAVE BEEN RAISED A FEW DEGREES MOST LOCATIONS.
MORNING SOUNDINGS AT RNK AND GSO SHOW A CAP- FAIRLY STRONG AT
GSO...GENERALLY 800 TO 750 MBS. LOOKING AT UPSTREAM
SOUNDINGS...THINK THAT THIS WARM LAYER WILL BE COOLING SOME. AM
REASONABLY CONFIDENT THAT THERE WILL BE ENOUGH HEATING AND
INCREASE IN LOW LEVEL MOISTURE FOR THE CAP TO BE BROKEN IN THE
MTNS. NOT SO SURE ABOUT THE PIEDMONT AREAS. MODIFIED SOUNDINGS
SHOW THAT ONCE THE CAP IS BROKEN...SFC BASED CAPES WILL BE
MODERATELY UNSTABLE AROUND 1500 J/KG. THIS IN COMBINATION WITH
MODERATELY STRONG FAIRLY UNIDIRECTIONAL SHEAR WILL PROBABLY BE
ENOUGH TO SUPPORT MULTICELL STORMS. THERE IS ENOUGH SHEAR FOR
STRONGER STORMS TO HAVE ROTATING UPDRAFTS AND A THREAT OF LARGE
HAIL OR HIGH WINDS. EITHER WE WILL NEED TO WAIT FOR A LINE OR LINE
SEGMENTS AHEAD OF THE FRONT TO MOVE INTO THE WESTERN MTNS LATE IN
THE AFTERNOON..OR WE MAY ALSO SEE STORMS DEVELOP ALONG THE BLUE
RIDGE IN FAR SW VA AND NW NC. CURRENT FCST IS MORE ALONG THE LINES
OF PREFRONTAL CONVECTION MOVING IN FROM THE WEST. HAVE DECIDED TO
LEAVE AS IS AND MONITOR TRENDS...SINCE THE FCST DID NOT HAVE VERY
HIGH CHCS UNTIL 400 PM OR 500 PM WHICH SEEMS REASONABLE IN EITHER
SCENARIO.

PREVIOUS DISCUSSION...
MODELS WERE STILL SHOWING DIFFERENCES IN TIMING WITH THE
APPROACHING SURFACE FRONT AND UPPER TROF. UNTIL THE LOW ON THE
FRONT PASSES NORTH OF THE FORECAST AREA DONT EXPECT TO SEE MUCH
MOVEMENT EAST. CONSIDERING FRONT WAS STILL ALONG THE OHIO RIVER
VALLEY INTO SOUTHERN LOUISIANA...WILL TREND TOWARD THE SLOWER
SOLUTIONS. AT THIS TIME THE LOCAL WRF LOOKS REASONABLE BRINGING
THE FRONT THROUGH FROM 18Z/2PM IN THE WEST TO 06Z/2AM IN THE FAR
EASTERN COUNTY WARNING AREA. PRECIPITATION MAY EVEN TAKE UNTIL
20-22Z/4-6PM TO REACH THE FAR WESTERN COUNTY WARNING AREA. HAVE
ADJUSTED PROBABILITY OF RAIN TO ACCOUNT FOR THIS TIMING.

MUCH COLDER AIR COMES IN BEHIND THE FRONT WITH A SHARP DROP IN 850
MB TEMPERATURES BY WEDNESDAY MORNING. USED THE LAV GUIDANCE FOR
HOURLY TEMPERATURES TODAY WHICH STARTS TO DROP THE TEMPERATURES IN
THE FAR WEST DURING THE LATE AFTERNOON WHICH LINES UP WITH THE
EXPECTED TIMING OF THE COLD FRONT. AHEAD OF THE FRONT HIGH CLOUDS
WILL BE INCREASING BUT THERE SHOULD STILL BE ENOUGH SUN TO GET
MOST LOCATIONS IN THE WEST IN TO THE MID 70S AND IN THE EAST INTO
THE LOWER TO MID 80S.

&&

.SHORT TERM /WEDNESDAY THROUGH FRIDAY NIGHT/...
SHOWER ACTIVITY WILL DIMINISH ACROSS THE NORTH CAROLINA PIEDMONT
REGION AND SOUTHSIDE VIRGINIA THROUGH LATE WEDNESDAY MORNING AS HIGH
PRESSURE BUILDS INTO OUR AREA. HOWEVER...NORTHWESTERLY FLOW BEHIND
THE COLD FRONT WILL KEEP SHOWERS IN OUR FORECAST WEST OF THE BLUE
RIDGE THROUGH LATE WEDNESDAY EVENING...WITH SHOWER ACTIVITY
DECREASING FROM EAST TO WEST THROUGH THE DAY.

THE MAIN CONCERN FOR THE EARLY MORNING HOURS OF THURSDAY WILL BE THE
UNSEASONABLY COOL AIR MOVING INTO OUR AREA AS A DEEP UPPER LEVEL LOW
PRESSURE SYSTEM PASSES TO OUR NORTH. OVERNIGHT LOW TEMPERATURES WILL
RANGE FROM THE LOW 40S ACROSS THE PIEDMONT REGION...TO THE LOW 30S
ACROSS PORTIONS OF SOUTHEAST WEST VIRGINIA AND THE MOUNTAINS OF
NORTH CAROLINA. IN ADDITION...WIND SPEEDS WILL DIMINISH OVERNIGHT AS
CLOUD COVER DECREASES...INTRODUCING THE POSSIBILITY OF FROST...EVEN
FOR AREAS WHERE THE LOW TEMPERATURE ONLY FALLS INTO THE MID 30S. AT
THIS POINT...IT WOULD BE A GOOD IDEA TO CONSIDER YOUR OPTIONS FOR
PROTECTING VEGETATION SUSCEPTIBLE TO NEAR FREEZING TEMPERATURES OR
FROST.

TEMPERATURES REBOUND ON THURSDAY AFTERNOON THANKS TO MOSTLY
CLEAR SKIES AND THE CONTINUED DEPARTURE OF THE UPPER LEVEL LOW. WE
CAN EXPECT SEASONABLE TEMPERATURES ON THURSDAY AFTERNOON...WITH
HIGHS RANGING FROM THE LOW 60S IN SOUTHEAST WEST VIRGINIA...TO
AROUND 70 IN THE NORTH CAROLINA PIEDMONT.

THE THREAT FOR FROST WILL BE SIGNIFICANTLY DIMINISHED EARLY FRIDAY
MORNING THANKS TO INCREASED CLOUD COVER...WHICH WILL HOLD LOW
TEMPERATURES IN THE MID 40S EAST TO THE MID 30S WEST. HOWEVER CANNOT
RULE OUT FROST DEVELOPING IN A FEW OF THE VALLEY BOTTOMS WEST OF THE
BLUE RIDGE. EXPECT A REINFORCING COLD FRONT TO PUSH INTO THE REGION
FROM THE MIDWEST ON FRIDAY AFTERNOON...WHICH WILL BRING SCATTERED
SHOWER ACTIVITY AND POSSIBLY A THUNDERSTORM OR TWO TO THE AREA.
SHOWER ACTIVITY WILL GRADUALLY DIMINISH THROUGH EVENING AS THE COLD
FRONT MOVES EAST OF THE AREA...AND HIGH PRESSURE AGAIN BECOMES THE
CONTROLLING FACTOR IN OUR WEATHER PATTERN.

&&

.LONG TERM /SATURDAY THROUGH MONDAY/...
THE LONG TERM PORTION OF THE FORECAST WILL BE DOMINATED BY TROUGHING
ACROSS EASTERN CANADA ND THE NORTHEAST U.S. THIS WILL KEEP THE
FORECAST AREA IN A RELATIVELY COOL NORTHWESTERLY FLOW FOR MOST OF
THE PERIOD...WITH A SERIES OF FAST MOVING SHORT WAVES AND ASSOCIATED
SFC FRONTS KEEPING A CHANCE OF PRECIPITATION FOR MOST OF THE PERIOD
AS WELL. TIMING FRONTS IN SUCH A PROGRESSIVE FLOW IS DIFFICULT IN
THE LONGER TERM. CURRENT FCST MAINTAINS GOOD CONTINUITY WITH THE
PREVIOUS LONGER TERM FCST.

A WARM FRONT WILL MOVE THROUGH SATURDAY NIGHT WITH THE STRONGEST
ISENTROPIC LIFT AND HIGHEST CHC OF PRECIP ACROSS THE NRN HALF OF
THE CWA. A STRONGER COLD FRONT THEN MOVES THROUGH THE AREA ON
SUNDAY BRING A CHANCE OF SHOWERS AND THUNDERSTORMS TO ALL AREAS.
MONDAY WILL BE BREEZY AND COOL WITH SCATTERED INSTABILITY SHOWERS
IN THE MTNS.

AS NOTED ABOVE...TEMPERATURES IN THIS PATTERN WILL TEND TO BE ON THE
COOL SIDE...AVERAGING NEAR TO BELOW NORMAL. AT THIS POINT...IT DOES
NOT LOOK LIKE TEMPERATURES REACH FREEZING ANY OF THE NIGHTS IN THE
LONG TERM...EVEN IN THE MTNS.

&&

.AVIATION /16Z TUESDAY THROUGH SATURDAY/...
EXPECT VFR CONDITIONS THROUGH 18Z TODAY WITH JUST HIGH CLOUDS
OCCASIONALLY COVERING THE WESTERN PART OF THE FORECAST AREA.

MODELS STILL SHOWING DIFFERENCES IN THE TIMING OF THE FRONT.
CONSIDERING THE FRONT IS NOT MOVING NOW...AM LEANING TOWARD THE
SLOWER SOLUTION WHICH DOES NOT BRING THE FRONT INTO THE WESTERN
PART OF THE COUNTY WARNING AREA UNTIL AROUND 00Z. HAVE USED THE
TIMING FROM THE SREF AND LOCAL WRF TO ADD THUNDERSTORMS TO THE
TAFS AND FOR THE WIND SHIFT WITH THE FRONTAL PASSAGE. KEPT
CEILINGS VFR WITH THE THUNDERSTORMS BUT ANY OF THE STRONGER CELLS
COULD HAVE MVFR OR EVEN IFR CEILINGS.

MODELS WERE SHOWING AMPLE LOW LEVEL MOISTURE BEHIND THE FRONT
TONIGHT AND WEDNESDAY...ESPECIALLY IN THE WESTERN UPSLOPE AREAS.
CEILINGS SHOULD LOWER AT BLF AND LWB TONIGHT. LOW CONFIDENCE AS TO
WHEN ON WEDNESDAY CONDITIONS WILL IMPROVE.

ARRIVAL OF SURFACE HIGH PRESSURE SHOULD SUPPORT RETURN TO VFR
WEATHER AT ALL TAF SITES FOR THURSDAY AND FRIDAY. THE NEXT CHANCE
OF SHOWERS AND THUNDERSTORMS WILL BE ON SATURDAY.
