AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 825 PM EDT SUN SEP 7 2014 .SYNOPSIS... HIGH PRESSURE WILL BUILD ACROSS THE OHIO VALLEY INTO NEW ENGLAND TONIGHT AS A COLD FRONT STALLS OVER NORTH CAROLINA. AN AREA OF LOW PRESSURE WILL DEVELOP ALONG THE FRONT LATER TONIGHT INTO MONDAY...THEN DRIFT SLOWLY NORTHEAST ALONG THE MID ATLANTIC COAST MONDAY NIGHT INTO TUESDAY. THIS SYSTEM WILL MAINTAIN A THREAT FOR SHOWERS AND THUNDERSTORMS OVER MUCH OF THE AREA THROUGH THE PERIOD. && .NEAR TERM /THROUGH MONDAY/... AS OF 250 PM EDT SUNDAY... UPPER TROUGH WILL PERSIST OVER THE EAST INTO MONDAY. MAIN SURFACE COLD FRONT HAS PUSHED SOUTH OF OUT AREA AND IS LOCATED ACROSS THE SOUTHEAST STATES THIS AFTERNOON. 1024 MB SFC HIGH IN THE OHIO VALLEY WILL BUILD EASTWARD INTO NEW ENGLAND. MEANWHILE...SURFACE TROF WILL DRIFT SOUTHEAST. THE COMBINATION OF AFTERNOON HEATING...ABUNDANT MOISTURE AND SFC TROF HAVE LEAD TO THE DEVELOPMENT OF SCATTERED SHOWERS...MAINLY IN THE WEST. WITH CAPES FROM 500 TO 1000 J/KG...AND SFC BASED LIS FROM MINUS 1 TO MINUS 3...DECIDED TO ADD THE MENTION OF THUNDERSTORMS MAINLY IN THE SOUTHWEST PORTION OF THE FORECAST AREA. THE AFTERNOON CONVECTION IN THE WEST SHOULD DIMINISH WITH THE LOSS OF HEATING THIS EVENING. INITIALLY...LEANED POPS FOR THIS AFTERNOON INTO THIS EVENING TOWARDS A BLEND OF THE RNKWRFARW...NAM...RAP...THEN SHAPED TONIGHT INTO MONDAY POPS TOWARDS THE SUPERBLEND TO CAPTURE THE WESTERN EXTENT OF THE PRECIPITATION SHIELD ASSOCIATED WITH A LOW PRESSURE SYSTEM WHICH TRACKS SLOWLY NORTHEAST ALONG THE COAST TONIGHT INTO MONDAY. AS HIGH PRESSURE BUILDS EASTWARD TO OUR NORTH...A CLASSIC WEDGE OF STABLE AIR WILL DEVELOP ALONG THE EASTERN SLOPES OF THE APPALACHIANS. TO OUR SOUTH...THE STALL FRONT WILL MERGE WITH A REMNANT SUB-TROPICAL LOW WHICH HAS BEEN SPINNING JUST INLAND OF THE GEORGIA COAST. ALL FORECAST MODELS TO VARYING DEGREES OF INTENSITY BEGIN TO STRENGTHEN THIS AREA OF LOW PRESSURE...MOVING IT NORTHEAST ALONG THE MID-ATLANTIC COAST TONIGHT INTO MONDAY. THE ECMWF AND GFS KEEP THE HEAVIEST RAIN EAST OF OUR FORECAST AREA. PLAYED TONIGHT LOW TEMPERATURES CLOSE TO THE ADJMAV...WITH READINGS FROM THE MID 50S IN THE MOUNTAINS TO THE MID 60S IN THE PIEDMONT. WITH CLOUDS AND PRECIPITATION...KEPT HIGH TEMPERATURES COOLER TOWARDS THE ADJMAVBC...WITH VALUES GENERALLY FROM THE UPPER 60S TO LOWER 70S. TEMPERATURES COULD BE COOLER DEPENDING ON THE INTENSITY AND COVERAGE OF THE RAIN ON MONDAY. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... AS OF 300 PM EDT SUNDAY... SHORT TERM PERIOD LIKELY TO BE CHARACTERIZED BY PERSISTENT COOL WEDGE THAT WILL TRAP PLENTY OF LOWER CLOUDS UNDER SLOWLY DEEPENING INVERSION LAYER...WITH WEAK MID LEVEL FORCING TO BE PROVIDED OVER COOL POOL DUE TO PASSAGE OF WEAK SHORT WAVE DRIFTING EAST MONDAY NIGHT THROUGH TUESDAY. WEAK FORCING ASSOCIATED WITH THIS SYSTEM SHOULD BE SUFFICIENT IN MAINTAINING AT LEAST A LOW THREAT FOR SCATTERED SHOWERS...ALTHOUGH TOTAL RAINFALL AMOUNTS THROUGH THE PERIOD ARE LIKELY TO REMAIN LESS THAN ONE TENTH OF AN INCH. AS WOULD BE EXPECTED WITH ABUNDANT CLOUD COVER...DIURNAL TEMPERATURE CURVE SHOULD BE FLATTENED...WITH DAYTIME HIGHS MAINLY IN THE 70S...WITH OVERNIGHT LOWS RANGING FROM THE 50S IN THE MOUNTAINS TO LOWER TO MID 60S PIEDMONT. PASSAGE OF WAVE TUESDAY NIGHT INTO EARLY WEDNESDAY SHOULD ALLOW FOR BRIEF PERIOD OF DRY WEATHER IN MOST OF THE FORECAST AREA...BUT INCREASING FORCING IN ADVANCE OF NEXT UPSTREAM SHORT WAVE AND SLOWLY BACKING OF WINDS ALOFT MAY BE SUFFICIENT TO REIGNITE SHOWERS... POSSIBLY THUNDERSTORMS...IN THE MOUNTAINS BY MID TO LATE AFTERNOON ON WEDNESDAY. ONSET OF WARM ADVECTION IN ADVANCE OF THIS WAVE SHOULD HELP TO SCOUR OUT WEDGE SUFFICIENTLY ON WEDNESDAY TO ALLOW FOR MORE INSOLATION...WITH DAYTIME HIGHS EXPECTED TO BE A BIT HIGHER...RANGING FROM MID 70S ACROSS THE HIGHER ELEVATIONS TO THE MID 80S ACROSS THE PIEDMONT. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... AS OF 300 PM EDT SUNDAY... SIGNIFICANT CHANGES TOWARD A PROLONGED PERIOD OF COOL WEATHER IS EXPECTED DURING AND BEYOND THE LONG TERM PERIOD AS MEAN AND BROAD UPPER RIDGE OVER THE GULF COAST AND SOUTHEASTERN STATES SLOWLY RETROGRESSES WESTWARD INTO THE SOUTHERN PLAINS IN RESPONSE TO A SERIES OF VERY STRONG SHORT WAVES THAT WILL HELP CARVE OUT AN IMPRESSIVE BROAD UPPER TROF FROM THE NORTHERN PLAINS EAST THROUGH THE GREAT LAKES INTO NEW ENGLAND. STABILITY OF THIS PATTERN WELL BEYOND THE LONG TERM PERIOD IS FAVORED CONSIDERING DEVELOPMENT OF VERY SUPPORTIVE BLOCKY UPPER PATTERN SETTING UP...WITH DEEP CLOSED LOW OVER ALASKA...AMPLIFYING DOWNSTREAM RIDGE OVER WESTERN CONUS...AND ADDITIONAL BLOCKING RIDGE AMPLIFYING AND PUSHING NORTH INTO THE NORTHERN ATLANTIC. ALTHOUGH WARM CONDITIONS ARE EXPECTED INITIALLY WEDNESDAY NIGHT INTO THURSDAY MORNING...DOWNWARD TREND WILL BEGIN LATER THURSDAY INTO THURSDAY NIGHT WITH APPROACH AND PASSAGE OF FIRST WAVE AND ASSOCIATED COLD FRONT...LIKELY TO BE PRECEDED AND ACCOMPANIED BY SCATTERED TO NUMEROUS SHOWERS/THUNDERSTORMS. HOWEVER...NEXT APPROACHING SHORT WAVE EXPECTED TO TEMPORARILY BUCKLE/CAUSE WINDS ALOFT TO BACK...SUCH THAT SOUTHWARD PROGRESSION OF FRONT WILL BE SLOWED/STALLS OVER OR JUST SOUTH OF THE BLACKSBURG FORECAST AREA...WITH INCREASING THREAT FOR OVERRUNNING MORE STRATIFORM PRECIPITATION LATER THURSDAY NIGHT INTO FRIDAY. PASSAGE OF SECOND WAVE AND APPROACH AND AMPLIFICATION OF SURFACE RIDGE TO OUR NORTH SHOULD GRADUALLY HELP BAROCLINIC ZONE TO BE PUSHED SUFFICIENTLY SOUTH TO GRADUALLY REDUCE THREAT OF ANY ADDITIONAL PRECIPITATION BY LATER SATURDAY INTO SUNDAY...BUT ANOTHER COOL WEDGE WILL ALSO LIKELY DEVELOP AS SURFACE HIGHS BUILDS SOUTHWESTWARD OUT OF NEW ENGLAND...MAINTAINING AT LEAST THE THREAT OF SOME STRATO- CUMULUS THROUGH THE WEEKEND WHICH WILL AGAIN FLATTEN THE DIURNAL TEMPERATURE CURVE (I.E. COOLER BY DAY AND MILDER AT NIGHT THAN WOULD OTHERWISE BE EXPECTED IF SKIES WERE TO REMAIN CLEAR). ASSUMING THAT A DIRTY WEDGE SETS UP...EXPECT DAYTIME HIGHS BY NEXT WEEKEND TO BE LIMITED TO THE UPPER 50S TO MID 60S IN THE MOUNTAINS TO THE LOWER 70S ACROSS THE PIEDMONT...WITH LOWS IN THE 40S MOUNTAINS TO 50S EAST OF THE BLUE RIDGE. HOWEVER...ONE THING TO WATCH WILL BE IF THE SURFACE HIGH BUILDS EVEN FURTHER SOUTH THAN CURRENTLY ANTICIPATED...WHICH WOULD SUPPORT A MORE AGGRESSIVE INTRUSION OF DEEPER DRY AIR AND LOWER DEW POINTS...AND ALSO ALLOW SKIES TO CLEAR A BIT MORE THAN EXPECTED. IF THIS OCCURS...SOME ISOLATED EARLY-SEASON FROSTS MAY EVEN BE POSSIBLE IN SOME OF THE DEEPER MOUNTAIN VALLEYS. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... AS OF 815 PM EDT SUNDAY... BAND OF MODERATE SHOWERS AND ISOLATED THUNDERSTORMS DEVELOPED FROM JUST SOUTH OF KROA AND KBCB INTO THE NORTHWEST NORTH CAROLINA MOUNTAINS. THESE SHOWERS AND THUNDERSTORMS WILL GRADUALLY DIMINISH IN INTENSITY AND COVERAGE BY 04Z/MIDNIGHT. BUFKIT SOUNDINGS SHOWED A DEEP LAYER OF MOISTURE THIS EVENING THAT WILL GRADUALLY DRY OUT FROM UPPER LEVELS DOWN TO JUST ABOVE THE SURFACE ON MONDAY AND MONDAY NIGHT. HIGH PRESSURE WAS ALREADY WEDGING DOWN THE EAST SLOPES OF THE APPALACHIANS. THIS WILL KEEP AN EASTERLY ONSHORE COMPONENT TO THE SURFACE AND LOW LEVEL WINDS. HIGH CONFIDENCE OF ABUNDANT LOW LEVEL MOISTURE AND CEILINGS LOWERING TO MVFR THEN IFR TONIGHT. AS STABILITY INCREASES THE THREAT OF THUNDERSTORMS WILL DIMINISH BUT THERE WILL STILL BE PERIODS OF LIGHT RAIN. HAVE ADDED LOW LEVEL WIND SHEAR IN FOR KDAN AND KLYH ON MONDAY. EXPECTING LOW LEVEL JET TO INCREASE BETWEEN THE STRENGTHENING WEDGE OF HIGH PRESSURE AND LOW PRESSURE OVER THE CAROLINAS. AFTER TUESDAY A RETURN TO SUMMER-LIKE CONDITIONS CAN BE EXPECTED WITH DIURNAL SHOWERS AND STORMS. LATE NIGHT FOG IS ALSO LIKELY IN THE MOUNTAIN VALLEYS. ANOTHER COLD FRONT IS FORECAST TO MOVE ACROSS THE MIDWEST AND OHIO VALLEY WEDNESDAY WITH STRONG AREA OF LOW PRESSURE MOVING INTO THE GREAT LAKES IMPACTING ROUTES THROUGH DTX-ORD-MSP. THIS FRONT SHOULD REACH THE MID ATLANTIC REGION IN THE THURSDAY/FRIDAY TIME FRAME. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...NONE. NC...NONE.

The national radar mosaic for the moment the first event began.
2 flood, 1 strong wind. Local standard time, as filed.
Heavy rain caused the Aho Branch Creek to overflow its banks and flow over Aho Road.
Heavy rainfall caused the East Fork and the South Fork of the New River to flood in the Boone area, causing many roadways to be closed due to water flowing over them. During the evening, Deerfield Road at the Moose Lodge was flooded, as well as Deerfield Road between State Farm Road and Blairmont Drive. Casey Lane was flooded and impassible. Bamboo Road was flooded and closed between Candy Lane and Kellwood Drive. Flooding was also observed in the parking lot of the Boone Mall.
The combination of gusty winds and very wet soil conditions from heavy rain caused a tree to fall, blocking Incline Drive in the community of Vilas.
