Special Weather Statement, NWS Blacksburg, VA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
717 PM EDT FRI AUG 23 2013

.SYNOPSIS...
DRIER AND SOMEWHAT COOLER HIGH PRESSURE WILL SETTLE OVER THE AREA
BEHIND A COOL FRONT TONIGHT AND INTO THE WEEKEND. MOISTURE WILL
BEGIN TO VERY SLOWLY RETURN TO THE REGION THROUGHOUT NEXT WEEK.
&&

.NEAR TERM /THROUGH SATURDAY/...
AS OF 342 PM EDT FRIDAY...

THE COLD FRONT CONTINUES TO MARCH TOWARDS THE AREA LATE THIS
AFTERNOON AND WILL SLOWLY MOVE SOUTH OF THE AREA TONIGHT. AREAS THAT
SAW RAIN EARLIER TODAY...SE WV-EXTREME SW VA...ARE STILL BEHIND THE
THETA-E/DEW POINT BOUNDARY. THIS BOUNDARY JUST MOVED SOUTH OF
PITTSBURGH PA AT 300 PM. THE COMBINATION OF MOISTURE AND HEATING
WILL KEEP NON-SEVERE SCATTERED CONVECTION OVER THE WEST UNTIL EARLY
THIS EVENING. THE STRONGER CONVECTION IS CURRENTLY MOVING ACROSS THE
SOUTHERN SHENANDOAH/ROANOKE VALLEYS AND SOUTH-CENTRAL VIRGINIA
PIEDMONT THIS AFTERNOON. THIS CONVECTION WILL WORK ITS WAY SOUTH TO
THE NC/VA BORDER THIS EVENING. THE PIEDMONT HAS SEEN MORE HEATING
TODAY AND SCATTERED STRONG TO ISOLATED SEVERE STORMS ARE POSSIBLE
THROUGH 10 PM. THIS STRONGER CONVECTION IS MOVING TO THE SOUTHEAST
AROUND 20 MPH WITH RAINFALL RATES OF 3 TO 5 INCHES PER HOUR. IF
THESE STORMS SLOW DOWN AND MAINTAIN THESE RAINFALL RATES...STREET
FLOODING WILL LIKELY RESULT.

ALL MODELS SHOWING VIABLE SOLUTIONS FOR THIS EVENING WITH KEEPING
SHOWERS AND THUNDERSTORMS ACROSS THE SOUTHEAST CORNER OF RNK CWA
THROUGH MIDNIGHT. I FAVORED AND BLENDED THE 12Z NAM AND 16Z HRRR.
THESE MODELS CAPTURED CURRENT SHOWERS OVER THE AREA AT THE TIME.
ONCE THE SHOWERS EXIT...THE THETA-E BOUNDARY WILL REMAIN OVER THE
AREA. WITH A MOIST SOUTHEAST FLOW...LOW LEVEL CLOUDS AND POSSIBLE
DRIZZLE SHOULD REMAIN INTO SATURDAY MORNING. DRY AIR BY MID MORNING
WILL QUICKLY CLEAR THE SKIES BY THE AFTERNOON. ALSO WITH LOW CLOUDS
IN THE REGION...AREAS OF DENSE FOG WILL NOT BE WIDESPREAD.

COOLER THAN NORMAL TEMPERATURES AND A NOTICEABLE DRIER DEW POINTS ARE
ON TAP FOR SATURDAY. TEMPERATURES WILL RANGE FROM THE MID TO UPPER
70S ACROSS THE WEST AND UPPER 70S TO LOWER 80S IN THE EAST. DEW
POINTS FOR THE AREA WILL BE IN THE 50S.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
AS OF 355 PM EDT FRIDAY...

RELATIVELY DRY AND COOL HIGH PRESSURE CENTERED OVER THE MID
ATLANTIC IS EXPECTED TO DOMINATE THIS PERIOD. NO SIGNS OF ANY
CHANCE OF RETURNING MOISTURE UNTIL POSSIBLY MONDAY AFTERNOON IN
TEH FAR WEST WITH SFC HIGH DRIFTING OVER WRN NC BY THIS TIME AND
850 FLOW WEAK BUT BEGINNING TO SHOW BETTER WESTERLY COMPONENT.
THIS TIME OF YEAR IT DOES NOT TAKE TOO LONG BEFORE JUST ENOUGH
LOVE LEVEL MOISTURE SNEAKS BACK IN FOR AT LEAST SOME ISOLATED MTN
SHOWERS. KEPT SLIGHT CHC CONFINED TO WESTERN SLOPES BASICALLY.
ADDED SOME PATCHY VALLEY FOG FOR SUNDAY MORNING GIVEN HIGH
BASICALLY OVERHEAD AND LITTLE IF ANY CLOUDS EXPECTED.

HIGH TEMPS AT OR BELOW SEASONAL LEVELS BUT WENT WITH WARMER
GUIDANCE GIVEN DRY RIDGE WITH PLENTY OF SUN...AND THEN LOW TEMPS
INITIALLY BELOW NORMAL GIVEN CLEAR BUT DRY NIGHTS. WENT WITH
COOLER MET GUIDANCE FOR LOWS SAT NIGHT AND SUNDAY NIGHT. BY
MONDAY NIGHT LOWS MAY GET BACK TO AT OR ABOVE SEASONAL NORMS WITH
LOW LEVEL MSTR ON THE SLOW INCREASE.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
AS OF 200 PM EDT FRIDAY...

LARGE HIGH PRESSURE DOME OVER CENTRAL U.S. GRADUALLY RETROGRADES
WEST DURING THE MID TO LATE PART OF THE WEEK...WITH A GRADUAL SET UP
OF WEAK UPPER TROUGH OVER NORTHEAST U.S. AND BETTER NW FLOW AND
CHANCES FOR SOME ORGANIZED CONVECTIVE SYSTEMS RIDING OVER TOP OF
RIDGE TO MAKE THEIR WAY INTO WESTERN OR NORTHWESTERN PORTIONS OF OUR
AREA. VERY HARD TO BE ABLE TO PIN POINT WHICH DAY IS MOST LIKELY FOR
THIS TO FIRST HAPPEN. 12Z GFS MOST AGGRESSIVE AT DEVELOPING THE
UPPER LEVEL WEAKNESS BY AS EARLY AS LATE TUES INTO WED...WITH 00Z
ECMWF AND 12Z CANADIAN IN GOOD AGREEMENT THAT IT MAY BE THURS BEFORE
THIS HAPPENS.  GFS ALSO TRYING TO SHOW BETTER RETURN OF MSTR UNDER
THE RIDGE AS EARLY AS TUES FOR ISOLD TO SCT MOUNTAIN SHWRS AND
TSTORMS DEVELOPING EACH DAY...WHEREAS OTHER MODELS APPEAR TO HAVE
SUBSIDENCE WITH RIDGE DOMINATING.  BASED ON CLIMATOLOGY WITH THIS
KIND OF PATTERN...WILL LEAN TOWARD GFS IDEA OF RETURN OF DAILY
MAINLY MTN SCATTERED CONVECTION BY TUES...BUT THEN BETTER CHANCES
FOR SOMETHING MORE ORGANIZED MOVING INTO WEST BY WED OR WED
NIGHT.

THE OTHER DIFFERENCE BETWEEN THE GUIDANCE IS HOW QUICKLY THIS BACK
SIDE OF THE WEAK TROUGH IS ABLE TO SWING A BACK DOOR COLD FRONT
THROUGH THE AREA AND HOW FAR SOUTH IT MAKES IT. OF COURSE MUCH OF
THIS MAY DEPEND ON TO WHAT EXTENT ORGANIZED CONVECTION RIDING OVER
THE NE EDGE OF THE BIG RIDGE MAY DEVELOP AND HELP PULL THIS BOUNDARY
DOWN. GFS FASTEST WITH THE FRONTAL PASSAGE AND BRINGS THIS THROUGH
EARLY THURSDAY...WITH ECMWF SLOWER AND MORE LIKE LATE THURSDAY OR
THURS NIGHT. THEN BY FRIDAY ECMWF A LITTLE SLOWER TO DRAG BACK END
OF FRONT AND LINGERING LOW LEVEL MOISTURE OUT OF THE SOUTHERN
APPALACHIANS...THUS SUGGESTING BETTER LINGER THREAT OF SOME ACTIVITY
FRIDAY ACROSS OUR SOUTHWEST.  FOR NOW...USED A VERY BROAD BRUSH AND
ERRED ON THE SIDE OF SLOWER REMOVAL OF MOISTURE THINKING FRONT MAY
NOT PUSH AS FAR SOUTH OF US AS MODELS GENERALLY SUGGEST.  SO LEFT
SOME CHC POPS ACROSS THE SOUTHWEST AND KEPT SLIGHT CHC UP EVERYWHERE
ELSE.  WITH THE UPSTREAM CONVECTIVE SYSTEMS DICTATING A LOT OF WHAT
WILL HAPPEN WITH THE BALANCE BETWEEN THE STRONG UPPER RIDGE TO OUR
WEST AND WEAK TROUGH OVER NORTHEAST U.S....JUST TOO MUCH UNCERTAINTY
THAT FAR OUT TO SAY FRO SURE WHEN...IF AT ALL...IT MAY DRY BACK OUT.

TEMPERATURE WISE...SLOW ARMING TREND EARLY PART OF PERIOD AS RIDGE
DOMINATES...THEN SLIGHT COOLING TREND WITH BETTER CHANCES FOR
CONVECTIVE AND ASSOC CLOUD COVER/PRECIP...AND POSSIBLE MORE
SIGNIFICANT DRYING OUT AND COOLER MINS BY THURS NIGHT OR FRI NIGHT
IF BACK DOOR FRONT CAN PUSH THROUGH.  HIGHS GENERALLY CLOSE TO
NORMAL...BUT LOWS PROBABLY TENDING ABOVE NORMAL WITH MSTR RETURN BY
MID WEEK. WENT CLOSE TO ECMWF MOS GUDIANCE.

&&

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
AS OF 645 PM EDT FRIDAY...

SURFACE COLD FRONT HAS SLOWED UP ACROSS THE PIEDMONT WHERE SEEING
CLUSTERS OF SHRA/TSRA LINGER MAINLY SOUTH AND WEST OF KDAN.
OUTFLOW HEADING WEST FROM THIS CONVECTION MAY SPAWN ADDED SHRA
FARTHER WEST OVER THE NEXT COUPLE OF HOURS BEFORE LOSS OF HEATING
CAUSES MOST PRECIP TO FADE THIS EVENING. THUS THINKING THAT MOST
SHRA WILL BASICALLY STAY AWAY FROM THE TAF LOCATIONS WITH PERHAPS
ONLY A BRIEF ADDED SHRA AT KDAN AND POSSIBLY KBCB. OTRW GUSTY
NORTH/NE WINDS SURGING IN BEHIND THIS BOUNDARY/CONVECTION WILL
KEEP GUSTS TO 20-25 KTS ALONG/EAST OF THE BLUE RIDGE BEFORE SPEEDS
DIMINISH AFTER SUNSET.

FOLLOWING THE FRONTAL PASSAGE THIS EVENING...MOIST LOW LEVELS AND
AND EASTERLY FLOW SHOULD KEEP LOW CLOUDS IN THROUGH THE NIGHT.
SOME PLACES ACROSS THE WEST MAY ALSO HAVE SPOTTY DRIZZLE
OVERNIGHT BUT CONFIDENCE LOW OUTSIDE OF KBLF. THUS WILL MAINTAIN
MORE OF A FOG MENTION ELSW AND BEEF UP FOG TO MORE IFR LEVELS AT
KDAN LATE TONIGHT IN THE WAKE OF THE HEAVIER RAINFALL FROM
EARLIER. DESPITE DRY ADVECTION WORKING IN STILL EXPECTING MOST
SITES TO EXPERIENCE A PERIOD OF MVFR CIGS/VSBYS WITH IFR PERHAPS
MORE PREVALENT AT KLWB PER VALLEY FOG...AND KBLF FOR LOW CIGS
GIVEN UPSLOPE FLOW.

HIGH PRESSURE WILL CONTROL THE WEATHER PATTERN FOR THE WEEKEND.
OTHER THAN SOME OVERNIGHT RIVER VALLEY FOG...VFR CONDITIONS ARE
EXPECTED SATURDAY INTO MONDAY. EXPECT A RETURN OF SPOTTY SHOWERS
AND THUNDERSTORMS IN THE MOUNTAINS FOR TUESDAY WITH COVERAGE OF
SHOWERS/STORMS INCREASING ESPCLY MOUNTAINS ON WEDNESDAY.
