The episode as NWS RNK wrote it up.
An upper trough was observed passing north along the Appalachian Mountains, while surface high pressure was observed wedging southward from New England across the mid-Atlantic region. The upper trough trigger a band of locally heavy rain with a few embedded thunderstorms. Despite the presence of the high pressure wedge, strong downdraft winds were able to reach the surface, producing localized damage to a tree. Wind gusts at nearby weather observing stations reported 25 mph to 30 mph wind gusts.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 906 PM EDT WED SEP 24 2014 .SYNOPSIS... LOW PRESSURE TRACKS NORTH ALONG THE COAST OF VIRGINIA TONIGHT AND OFF THE DELAWARE COAST THURSDAY. HIGH PRESSURE BUILDS SOUTHWARD FROM THE GREAT LAKES FRIDAY INTO SATURDAY. THE NEXT THREAT OF RAIN WILL BE FROM A STORM SYSTEM MOVING UP FROM THE GULF COAST STATES EARLY NEXT WEEK. && .NEAR TERM /THROUGH THURSDAY/... AS OF 830 PM EDT WEDNESDAY... STEADIEST/HEAVIEST RAIN REMAINS CONFINED TO AREAS GENERALLY EAST OF HIGHWAY 29 IN THE EAST THIS EVENING WITH MAINLY SPOTTY -RA/DZ FARTHER WEST WHERE REMOVED FROM THE AXIS OF DEEPER MOISTURE. THIS HAS RESULTED IN SOME SPOTS OVER THE VIRGINIA PIEDMONT PICKING UP AROUND AN INCH OF RAIN SINCE THIS MORNING WITH RATHER WIDESPREAD QUARTER TO HALF INCH AMOUNTS SOUTH AND EAST OF LYH. THIS IN ASSOCIATION WITH A QUITE COMPLICATED SCENARIO GIVEN THE BROAD 5H UPPER LOW OVER WEST VA THIS EVENING...EMBEDDED SHORTWAVE ENERGY OVER SE VIRGINIA...AND THE ACTUAL SURFACE LOW ALONG THE OUTER BANKS. THIS SETUP HAS RESULTED IN QUITE A DIFFLUENT UPPER PATTERN OVER THE EAST WHERE FED BY A STRONG 30-35 KT EASTERLY JET UNDER THE UPPER SUPPORT. MODELS HAVE BEEN TOO FAST TO EXIT THE MOISTURE UNDER THE WAVE ALOFT AS THE CURRENT DIFFLUENCE ALOFT BETWEEN THE UPPER SYSTEM AND THE COASTAL LOW HAS KEPT THE CONVERGENCE AXIS LOCKED IN. APPEARS ONCE THE SURFACE LOW FINALLY STARTS TO LIFT OUT TO THE NORTH AFTER MIDNIGHT SHOULD SEE THE STEADY RAIN START TO TAPER SOME WITH MAINLY JUST SPOTTY -RA/-DZ PERSISTING WEST UNDER THE STRONG LOW LEVEL FLOW AND SOME DEGREE OF UPSLOPE BLUE RIDGE. THUS HAVE EXTENDED THE LIKELY/CAT POPS PIEDMONT A BIT LONGER BASED ON CURRENT TRENDS...AND KEPT LOW CHANCES ESPCLY BLUE RIDGE EAST OVERNIGHT FOR SOME WRAP AROUND -RA THREAT AS THE MAIN PRECIP SHIELD EXITS. NE WINDS REMAIN GUSTY EASTERN HALF AS PERIODIC GUSTS MIX DOWN ESPCLY ON THE BACKEDGE OF THE RAIN SHIELD WHERE LIKELY SEEING A LITTLE DRYING. THEREFORE BUMPED GUSTS TOWARD 25-30 KTS FOR A FEW MORE HOURS OUT EAST. OTRW TEMPS SLOW TO FALL AND SHOULD STAY ABOUT STEADY A WHILE LONGER BEFORE SEEING SOME DROP WEST WHERE CLOUDS SHOULD THIN LATER ON. OTRW LOWS MOSTLY IN THE 50S FOR NOW. THURSDAY STARTS CLOUDY...WITH SFC LOW OFF THE COAST OF DELAWARE LIFTING NE. STILL LOOKING AT WEDGE IN PLACE WITH WEAK UPPER TROUGH...AND THINK WE CAN EXPECT PATCHY DZ AND LIGHT RAIN ALONG THE BLUE RIDGE EARLY...THEN SLIGHT CHANCE OF SHOWERS WITH UPPER SUPPORT OVER THE SW CWA LATE. COULD SEE MORE SUNSHINE RETURNING OVER THE FAR WRN CWA FROM RAINELLE TO BLUEFIELD WV SOUTHWEST TO CHILHOWIE AND BEECH MOUNTAIN....WITH THE EASTERN CWA STAYING MOSTLY CLOUDY TO OVERCAST. HIGH TEMPS WILL BE A SOMEWHAT WARMER WITH LACK OF RAIN BUT STAYING IN THE MID TO UPPER 60S PIEDMONT...SOME LOWER 70S AROUND THE ROANOKE/SRN SHENANDOAH VALLEY SOUTH TO THE NC FOOTHILLS...AS WELL AS THE WV/FAR SW VA AREA. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... AS OF 400 PM EDT WEDNESDAY... PROGRESSION OF WEATHER SYSTEMS HAS SLOWED TO A CRAWL PER BLOCKY SYNOPTIC PATTERN. UPPER LEVEL HIGH PRESSURE COVERS MUCH OF THE EASTERN 2/3RDS OF THE NATION WITH CLOSED SMALLER SCALE LOWS EMBEDDED WITHIN THE STAGNANT FLOW. SURFACE BAROCLINIC ZONE...STATIONARY FRONT...REMAINS ALONG SOUTHEAST ATLANTIC COAST AND STRETCHES WEST ALONG THE GULF COAST. WEATHER THROUGH THE UPCOMING WEEKEND FOR THE CENTRAL APPALACHIANS LOOKS RELATIVELY QUIET. WEAK EASTERLY FLOW MAY RESULT IN PERIODS OF CLOUDINESS...BUT RAIN THREATS WILL BE PRIMARILY CONFINED TO THE COASTS FROM THE MID-ATLANTIC SOUTH TO FLORIDA...THEN WEST ALONG THE GULF COAST. WITH 85H TEMPS RETURNING TO THE LOWER DOUBLE DIGITS THIS WEEKEND...+12 TO +14 DEG C...LOOKING AT SURFACE READINGS IN THE 70S FOR HIGHS AND 50S/L60S FOR LOWS. SOME OF THE MODEL MOS HINTED THE LOWER ELEVATIONS MAY REACH 80 FOR BOTH FRIDAY AND SATURDAY... BUT WE SHIED AWAY FROM THIS NUMBER PER EASTERLY FLOW WHICH TYPICALLY BRINGS MORE CLOUD COVER AND A CHAOTIC SKY. AT THE VERY LEAST MAYBE WE CAN CAPTURE SOME MORE BRILLIANT SUNSET PHOTOS THAT HAVE BEEN TRICKLING IN FORM THE SOCIAL MEDIA THIS PAST WEEK. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... AS OF 415 PM EDT WEDNESDAY... SLUGGISH SYNOPTIC PATTERN CONTINUES EARLY NEXT WEEK WITH CHAOTIC UPPER LEVEL FLOW. MODELS ARE IN AGREEMENT THAT GULF MOISTURE WILL CONGEAL NEAR THE TEXAS GULF COAST...POSSIBLY FROM A TROPICAL DISTURBANCE...THEN INCREASE IN COVERAGE ACROSS THE SOUTHEAST STATES SUNDAY INTO MONDAY. STATIONARY FRONT ALONG THE GULF COAST IS FORECAST TO BECOME THE FOCUS FOR OVERRUNNING RAINS ACROSS THE LOWER MISSISSIPPI VALLEY...THIS FRONT AND ASSOCIATED MOISTURE LIFTING NORTH TOWARD OUR REGION EARLY IN THE WEEK. ATTM THE GFS IS ABOUT 12-18 HOURS FASTER THAN THE ECMWF WITH THE ARRIVAL OF THIS RAINFALL...GFS ONSET LATE SUNDAY NIGHT-EARLY MONDAY AS OPPOSED TO THE ECMWF ONSET MONDAY NIGHT. PER THE SLOW BLOCKY FLOW...THE FORECAST REFLECTS THE SLOWER ECMWF. DID BRING CHANCE THREAT FOR PRECIP INTO THE NORTH CAROLINA MOUNTAINS MONDAY...BUT HELD OFF HIGHER POPS FOR AREAS FARTHER NORTH UNTIL MONDAY NIGHT AND TUESDAY. SKEWED HIGH TEMPERATURES DOWN MONDAY-WEDNESDAY TO ACCOUNT FOR CLOUD COVER AND PRECIPITATION...GUIDANCE TOO WARM PER EFFECTS FROM CLIMO. PER TROPICAL NATURE OF AIRMASS...NIGHT TIME LOWS WILL BE WARM...AND WELL ABOVE FREEZING. AS SUCH DO NOT FORESEE ANY THREAT OF FROST NEXT WEEK. THE 8-14 DAY OUTLOOK IS FOR MORE OF THE SAME...MOIST AND WARM...THUS WE MAY BE ABLE TO ESCAPE FROST THROUGH MID OCTOBER...JUST IN TIME FOR THE LEAVES TO CHANGE COLOR. && .AVIATION /01Z THURSDAY THROUGH MONDAY/... AS OF 815 PM EDT WEDNESDAY... RADAR INDICATES THE AREA OF HEAVIEST RAINFALL HAS MOVED NORTH OF KDAN THIS EVENING...AND WILL CONTINUE TO LIGHTEN IN INTENSITY AT KLYH OVER THE NEXT FEW HOURS...BEFORE BECOMING MORE ON AND OFF. FURTHER WEST...HAVE SEEN ONLY LIGHT RETURNS AFFECTING KROA/KBCB/ KBLF/KLWB. CEILINGS CONTINUE TO LOWER ACROSS MUCH OF THE REGION HOWEVER...PER LATEST SURFACE OBSERVATIONS...AND ALL AIRPORTS ARE REPORTING MAINLY MVFR CEILINGS ACROSS THE MOUNTAINS...AND IFR CEILINGS FURTHER EAST. OVERNIGHT...EXPECT NORTHEASTERLY FLOW TO CONTINUE TO PUSH LOW LEVEL MOISTURE INTO THE REGION...CAUSING CEILINGS TO LOWER TO IFR/LIFR FOR ALL AIRPORTS. ALSO EXPECT REDUCTIONS IN VISIBILITY IN LIGHT RAIN/DRIZZLE/FOG. LOW PRESSURE WILL CONTINUE NORTH ALONG THE COAST OVERNIGHT... SHIFTING OFF OF THE NEW ENGLAND COAST ON THURSDAY. EXPECT GRADUAL IMPROVEMENT OF LOW CEILINGS THROUGH LATE MORNING...WITH CEILINGS BECOMING MVFR INTERMIXED WITH LOW VFR BY EARLY AFTERNOON WITH INCREASED HEATING. EXTENDED AVIATION DISCUSSION... NORTHEASTERLY FLOW WILL REMAIN PERSISTENT THROUGH THE END OF THE WORKWEEK...WITH ANOTHER ROUND OF LOW STRATUS AND PATCHY DRIZZLE DEVELOPING ACROSS REGION THURSDAY NIGHT. BEST MOISTURE CONVERGENCE DRIFTS TOWARD THE SW PART OF THE FORECAST REGION WITH TIME AS THE WEDGE BOUNDARY PERSISTS ALLOWING SOME DRY AIR TO FILTER INTO NE SECTIONS BY FRIDAY. SOME MVFR CEILINGS MAY LINGER INTO FRIDAY MORNING BEFORE MOSTLY VFR CONDITIONS RETURN LATER FRIDAY AND CONTINUE INTO THE WEEKEND. THE NEXT INCLEMENT WEATHER SYSTEM DOES NOT IMPACT THE REGION UNTIL LATE MONDAY. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...NONE. NC...NONE.
