AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
348 PM EDT THU AUG 12 2010
.SYNOPSIS...
A WEAK COOL FRONT OVER NORTHERN VIRGINIA WILL SLIP SOUTHWARD AND
INTO THE CAROLINAS OVERNIGHT. AN EASTERLY WIND ON FRIDAY WILL
BRING SLIGHTLY COOLER WEATHER...PARTICULARLY EAST OF THE BLUE
RIDGE. HOWEVER...IT WILL REMAIN HUMID. WITH HIGH PRESSURE
SETTLING OVER NEW ENGLAND...A HUMID SOUTHEAST FLOW WILL CONTINUE
OVER THE WEEKEND. A MUCH STRONGER COLD FRONT WILL APPROACH THE
AREA FROM THE NORTHWEST EARLY NEXT WEEK.
&&
.NEAR TERM /THROUGH FRIDAY/...
NORTHWEST WINDS AND DRIER AIR HAS SUPPRESSED TSTM DEVELOPMENT
ACROSS MOST OF THE CWA AT THIS TIME. MOST LIKELY AREAS TO STILL
SEE A TSTM LATE THIS AFT AND THIS EVE WILL BE IN THE PIEDMONT FROM
LYH TO DAN LINE AND EASTWARD. ALSO IN FAR SW MTNS OF VA AND NW NC
MTNS AND FOOTHILLS. IF ANY STRONG TSTMS GET GOING...THEY WILL
LIKELY HAVE STRONG TO DAMAGING WIND GUSTS. WILL KEEP THE SVR TSTM
WATCH GOING FOR BUCKINGHAM...APPOMATTOX AND CHARLOTTE
COUNTIES...AS THESE LOCATIONS ARE CLOSEST TO THE TRAILING EDGE OF
A SHORT WAVE MOVG THRU NRN VA AT THIS TIME. HAVE KEPT SOME CHC
POPS GOING THRU THE EVENING IN THE EAST...THEN FOCUS WILL SHIFT TO
AN EASTERLY FLOW DEVELOPING BEHIND A BACK DOOR COLD FRONT. MODELS
SHOW MOISTURE DEEP ENOUGH FOR THE POSSIBILITY OF SHOWERS IN THE
EAST...WITH SOME STRATUS/FOG DEVELOPING. WITH AN EAST TO SOUTHEAST
FLOW FRIDAY...IF THERE IS CLOUD COVER IN THE EAST BEGINNING IN
THE MORNING...THEN IT MAY HOLD A GOOD PART OF THE DAY. WARMEST
TEMPS FRIDAY WILL LIKELY BE IN THE WESTERN MTNS- HAVE LEANED TEMP
FCST STRONGLY TOWARD COOLER MET GUIDANCE. ANY TSTM DEVELOPMENT
FRIDAY LOOKS MOST LIKELY ALONG THE BLUE RIDGE WITH THE UPSLOPE
FLOW.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT
SURFACE HIGH OVER NEW ENGLAND WEDGES DOWN THE EASTERN APPALACHIAN
MOUNTAINS AS WEAK RIDGING BUILDS ALOFT FRIDAY NIGHT. THIS WILL ALLOW
WINDS TO TURN MORE EASTERLY WHICH IS A FAVORABLE DIRECTION FOR
UPSLOPE TO OCCUR ALONG THE BLUE RIDGE MOUNTAINS. THIS MAY ENHANCE
THE PROBABILITY FOR AT LEAST DRIZZLE TO DEVELOP.
THE WEDGE WILL CONTINUE TO DIVE SOUTHWARD OVER THE SOUTHEASTERN
STATES SATURDAY. THERE WILL BE OVERRUNNING MOISTURE DUE TO AN UPPER
LEVEL LOW LOCATED OVER THE SOUTHEASTERN STATES. WINDS WILL VEER MORE
SOUTHERLY INTO SATURDAY AND SUNDAY ALLOWING FOR POSSIBLE BREAKS IN
THE CLOUD COVER. MODELS SUGGEST MOST OF THE PRECIP TO REMAIN IN THE
SOUTHERN PORTIONS OF THE FORECAST AREA MAINLY IN THE NORTHERN NORTH
CAROLINA MOUNTAINS AND FOOTHILLS. HOWEVER...IF THE BOUNDARY IS A
LITTLE FURTHER NORTH THE CHANCE FOR CONVECTION WILL INCREASE INTO
SOUTHERN VIRGINIA. LOOKING AT THE INSTABILITY PARAMETERS...NOT TOO
IMPRESSED WITH A HIGH CHANCE OF THUNDER BUT COULD SEE MOSTLY
SCATTERED SHOWERS WITH ISOLATED THUNDERSTORMS DEVELOPING IN THE
FAVORABLE AREAS SATURDAY. WITH EASTERLY FLOW PRESENT OVER THE AREA
SATURDAY NIGHT...DRIZZLE COULD FORM ONCE AGAIN ALONG THE MOUNTAINS.
PWATS INCREASE LATE IN THE WEEKEND TO CLOSE TO 2 INCHES...AND WITH
SW FLOW AND WEDGE LIKELY ERODING ACROSS MOST OF AREA...BETTER
CHANCES FOR THUNDER BY SUNDAY AFTERNOON.
TEMPERATURES WILL BE A CHALLENGE OVER THE WEEKEND WITH WEDGE
INFLUENCING MUCH OF THE AREA FOR SATURDAY THEN LIKELY ERODING
SOMEWHAT ON SUNDAY. VERY DEPENDENT ON DEPTH OF MOISTURE AND CLOUD
COVER AS WELL AS STRENGTH OF EASTERLY UPSLOPE. USED BIAS CORRECTED
MET FOR LOWS FRI...RESULTING IN A BIT MILDER GIVEN THE CLOUD COVER
IN MOIST SOUTHEAST FLOW. THEN WITH LIKELIHOOD OF WEDGE IN PLACE FOR
ALL BUT FAR SW FOR SATURDAY...WENT WITH OR SLIGHTLY BELOW COOLER MET
GUIDANCE FOR HIGHS. PREVIOUS FCST HIGHS FOR SUNDAY ACTUALLY LOOK
PRETTY GOOD IN THAT THEY ARE A FEW DEG COOLER THEN 12Z MAV...AT
LEAST FOR AREAS THAT ARE LIKELY TO SEE SOME LINGERING INFLUENCE FROM
THE WEDGE FOR PART OF THE DAY. STILL...WARMING NOTICEABLY FROM
SATURDAYS UNSEASONABLY COOL TEMPS.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
UPPER TROUGH APPROACHES THE REGION FROM THE NORTHWEST SUPPRESSING
THE UPPER RIDGE SOUTHWARD. WHILE AT THE SURFACE...A COLD FRONT
PUSHES INTO THE COUNTY WARNING AREA. EXPECT AT LEAST SCATTERED
COVERAGE OF CONVECTION AHEAD OF THIS COLD FRONT THROUGH MID WEEK.
CAPES LOOK TO RANGE FROM 1000 TO 1500 J/KG FOR BOTH MONDAY AND
TUESDAY AFTERNOON WITH LI/S AS LOW AS -5C TO -9C.
MODELS SHOW DIFFERENCES WITH THE END OF THE WEEK WITH THE 12Z GFS
SUGGESTING A HIGH PRESSURE FROM THE MID WEST BUILDING INTO THE AREA
LATE WEDNESDAY. IT ALSO SHOWS A TROPICAL LOW PUSHING UP FROM THE
LA/MS BORDER AND IMPACTING THE AREA BY THE WEEKEND. 00Z ECMWF
INDICATES WEAK SURFACE HIGH PRESSURE BUILDING IN BY THURSDAY WITH A
SLIGHTLY STRONGER TROPICAL LOW TRYING TO PUSH NORTHEAST TOWARD THE
FORECAST AREA BY THE WEEKEND.
TEMPERATURES THROUGH THE EXTENDED WILL RUN NEAR TO SLIGHTLY ABOVE
SEASONAL NORMS.
&&
.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
CONVECTIVE DEVELOPMENT THIS AFTERNOON WILL BE ISOLD TO SCT FROM
THE ROANOKE AREA WESTWARD...WHILE FURTHER EAST MAY SEE MORE
ORGANIZED TSTMS WITH DEEPER MOISTURE AND SOME LOW LEVEL
CONVERGENCE. A SHORT WAVE OVER SW PA...WILL MOVE ACROSS ERN VA BY
THIS EVE. THIS FEATURE IS EXPECTED TO ENHANCE TSTM DEVELOPMENT IN
THE VA AND NC PIEDMONTS. SO AIRPORTS WITH BEST CHC TO SEE A TSTM
WILL BE LYH AND DAN- WITH DAN HAVING THE BEST CHC...I HAVE KEPT A
TEMP GROUP FROM 13/21 - 13/23Z. ONCE THE THREAT OF TSTMS
PASSES...THE LOW LEVEL FLOW EAST OF THE MTNS WILL VEER TO THE
NORTHEAST TO EAST. WHILE MID LEVELS WILL DRY OUT...THERE WILL
STILL BE PLENTY OF LOW LEVEL MOISTURE...AND STRATUS/FOG IS LIKELY
IN THE PIEDMONT...AFFECTING LYH AND DAN. MEANWHILE...IN THE
MTNS...FOG WILL DEVELOP...AND LWB IS EXPECTED TO DROP TO
LIFR...WHILE BLF HAS A GOOD CHC OF DROPPING TO IFR BEFORE
DAYBREAK.
ANY FOG/STRATUS EAST OF THE BLUE RIDGE WILL BE SLOW TO LIFT
FRIDAY...AS THE LOW LEVEL FLOW WILL STRENGTHEN FROM THE EAST. LYH
AND DAN ARE EXPECTED TO GRADUALLY LIFT TO MVFR...BUT WILL LIKELY
REMAIN MVFR THROUGH 18Z FRIDAY. FURTHER WEST WILL LIKELY SCATTER
OUT BY AROUND NOON. THERE WILL BE A LOW CHC FOR AFT TSTMS AGAIN
FRIDAY...MAINLY ALONG THE BLUE RIDGE.
FOG AND STRATUS IS LIKELY AGAIN FRIDAY NIGHT AND INTO SATURDAY
MORNING WITH THE POTENTIAL FOR WIDESPREAD IFR.
CONDITIONS SHOULD IMPROVE SATURDAY INTO SUNDAY...BUT CONSIDERABLE
LOW LEVEL MOISTURE WILL REMAIN OVER THE REGION FOR DAILY THREAT OF
SHRA/TSRA. FOR THE OVERNIGHT PERIODS...EXPECT CONTINUED
FORMATION OF LATE NIGHT FOG...ESP IN THE MTN VALLEYS. IFR/LIFR
WILL BE MOST NOTABLE AT KLWB...CONDITIONS LIMITED MAINLY TO THE 09
UTC TO 13 UTC TIME FRAME FOR BOTH SUNDAY AND MONDAY MORNINGS.
LIGHT MORNING FOG IS POSSIBLE ELSEWHERE...SO A PERIOD OF MVFR
EXPECTED AT THE OTHER TERMINALS...AGAIN MAINLY CONFINED TO THE 09
UTC TO 13 UTC TIME FRAME.
