The episode as NWS RNK wrote it up.
Showers and storms developed by the early afternoon within an area of greater moisture across the central Appalachians. The storms were also fueled by good instability in the lower portion of the atmosphere and plenty of daytime heating. Some of these storms reached severe levels, producing damaging winds and large hail.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Sep 3, 1:23 PM EST, 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 223 PM EDT SAT SEP 3 2011 .SYNOPSIS... HIGH PRESSURE WILL DOMINATE THE AREAS WEATHER ONE MORE DAY AS IT SLOWLY SHIFTS OFFSHORE TONIGHT. A COLD FRONT WILL APPROACH LATE SUNDAY...AND MOVE INTO THE AREA AND STALL ON MONDAY. THIS FRONTAL BOUNDARY IS THEN EXPECTED TO REMAIN NEAR THE FORECAST AREA INTO MID WEEK. DEEP TROPICAL MOISTURE ASSOCIATED WITH TROPICAL STORM LEE WILL BE RIDING UP THE FRONT FROM MONDAY INTO MID WEEK. && .NEAR TERM /THROUGH TONIGHT/... AS OF 2:20 PM EDT SATURDAY... QUICK UPDATE TO INCREASE SOME POPS ACROSS PARTS FO THE NORTH...AND ACCUONT FOR LATEST SKY COVER PER SATELLITE IMAGERY. STRONG TO SEVERE...BUT SMALL SIZE...PULSE STORMS FIRING RAPIDLY ALONG HIGHER TERRAIN...AND MOVING SLOWLY OR BACKBUILDING IN WEAK UPPER LEVEL FLOW. HEAVY RAIN AND GUSTY WINDS BIGGEST THREATS REMAINDER OF AFTERNOON...MAINLY IN MTNS BUT ALSO FOOTHILLS NORTH OF 460. AS OF 11:55 AM EDT SATURDAY... ANOTHER MINOR ADJUSTMENT TO GRIDS TO ACCOUNT FOR PERSISTENT FOG/STRATUS IN NEW RIOVER VALLEY BUT THAT IS FINALLY DISSIPATING QUICKLY NOW. ADDED SOME SLIGHT CHC POPS TO FAR NE NEXT FEW HOURS PER AREA OF THUNDERSTORMS SLIDING SOUTHWARD OUT OF NRN VA. EXPECT THESE TO WEAKEN SOMEWHAT AS MTN RIDGES BECOME FOCUS FOR CONVECTION BEGINNING TO BUBBLE UP BY 1-2 PM WHERE MIXED LAYER CAPE VALUES ARE ALREADY 1500 IN SOME PLACES...AND EXPECTED TO GET TO 2000-2500 BY LATE AFTERNOON. PREV DISC AS OF 1015 AM EDT SATURDAY... PATCHY FOG AND SOME STRATUS HOLDING ON LONGER IN NEW RIVER VALLEY AND MAY NOT FINALLY BURN OFF IN SOME AREAS UNTIL ALMOST NOON GIVEN STERONG INVERSION SEE IN 12Z SOUNDING. ONCE INVERSION BREAKS...TEMPS SHOULD QUICKLY CLIMB INTO THE 80S...ALTHOUGH BACKED OFF A COUPLE DEG IN PARTS OF THE WEST GIVEN LINGERING FOG/STRATUS AND GOOD CHANCE FOR DEVELOPING STORMS BY MID AFTERNOON. VARIETY OF MESOSCALE MODEL GUIDANCE SUGGESTS GOOD CLUSTER OF CONVECTION DEVELOPING BY MID AFTERNOON ACROSS MTNS TO OUR NORTH ADN THEN UNZIPPING SOUTHWARD OR SOUTHWESTWARD GIVEN UPPER FLOW AND LIKELY OUTFLOW DOMINATED. COULD BE SOME GOOD CLUSTERS OF STORMS MUCH LIKE YESTERDAY...SO UPPED POPS IN THE WEST TO LOW LIKELY ACROSS FAR NORTH TO HIGH CHANCE ALL THE WAY DOWN TO SW VA MTNS. TODAY A BIT STRONGER INVERSION SO CONVECTION COULD WAIT TO GET STARTED UNTIL 3 OR 4PM...AND STEERING FLOW MORE TOWARD SW...BUT OTHERWISE MID LEVEL LAPSE RATES IMPRESSIVE AND MID LEVEL DRY AIR TO SUPPORT GUSTY WINDS WITH STORMS...VERY SIMILAR TO YESTERDAY. BEST CHANCE FOR ANY STORMS TO SPILL EAST OF THE BLUE RIDGE APPEARS MAINLY NORTH OF 460...AND MOVEMENT TOWARD SOUTH OR SOUTHWEST. PREV DISCUSSION AS OF 345 AM EDT SATURDAY... LOW CLOUDS AND FOG BANKED UP AGAINST THE BLUE RIDGE APPEARS TO BE FAIRLY SHALLOW...WITH THE EASTERN EDGE ALREADY SCATTERING OUT SOME. THINK THAT THESE CLOUDS WILL LIFT AND SCATTER OUT QUICKLY AFTER SUNRISE...SO MOST AREAS SHOULD SEE PLENTY OF SUN BY MID MORNING. MEANWHILE...THE UPPER RIDGE HOLDS OVER THE SOUTHERN APPLNS AND TN VALLEY...PRODUCING WEAK WIND FIELDS. MOISTURE HAS STEADILY INCREASED...WITH SFC DEWPOINTS IN THE MID 60S TO AROUND 70 AND PWATS AROUND 1.5 INCHES. WITH PLENTY OF HEATING EXPECTED TODAY...THINK THAT WE WILL SEE SB CAPES IF >2000 J/KG IN THE MTNS. IN ADDITION...DESPITE THE RIDGE BEING OVHD...MID LEVEL LAPSE RATES ARE STILL 6.0 TO 6.5 DEG C/KM...SUFFICIENT FOR DEEP CONVECTION. IT IS HARD TO FIND ANY LARGE SCALE FORCING...OTHER THAN TOPOGRAPHIC...WITH A LIGHT EAST TO SOUTHEAST FLOW INTO THE BLUE RIDGE. MODELS DO SHOW THE THETA-E RIDGE FURTHER WEST TODAY IN THE WESTERN MTNS...AND THERE IS SOME WEAK LOW LEVEL CONVERGENCE IN THE WESTERN MTNS AS WELL. THINK THAT THE BEST CHC FOR TSTMS WILL BE IN THE WESTERN CWA...ALSO BECAUSE THE STORM MOTION WILL BE TO THE SOUTHWEST OR WEST. I HAVE RAISED POPS TO 50 PCT IN THE MTN EMPIRE/SW MTNS OF VA...AND SE WV. WITH A SLOW STORM MOTION...AND THE POTENTIAL FOR DEEP CONVECTION TO BECOME ANCHORED ON EASTERN FACING SLOPES...ALONG WITH PWATS AROUND 150% OF NORMAL...I HAVE ADDED IN HEAVY RAIN TO THE AREAS WHERE I HAVE SCATTERED TSTMS- GENERALLY ALONG AND WEST OF THE BLUE RIDGE. LOWEST POPS TODAY ARE IN THE PIEDMONT. HAVE KEPT HIGHS TODAY ABOVE GUIDANCE...WHICH HAS BEEN TOO COOL. SHOULD BE AROUND 90 MOST OF THE AREA...EVEN IN THE MTNS. THE ONLY RECORD THAT LOOKS WITHIN REACH IS AT BLUEFIELD. WE ARE FORECASTING LEMONADE TEMPS AT BLUEFIELD AGAIN- HIGH OF 91. RECORD HIGH AT BLUEFIELD TODAY IS 88 SET IN 1993. CONVECTION SHOULD TAPER OFF QUICKLY WITH SUNSET AND LOSS OF HEATING...THEN I EXPECT AREAS OF FOG TO DEVELOP- ESPECIALLY IF THERE WAS GOOD COVERAGE OF STORMS. OVERNIGHT LOWS WILL CONTINUE TO BE WARM AND MUGGY. A RECORD HIGH MINIMUM TEMPERATURES IS POSSIBLE AGAIN AT BLUEFIELD. THE RECORD FOR SEPTEMBER 4TH IS 67 SET IN 1966. THE FORECAST LOW IS 71 DEGREES. && .SHORT TERM /SUNDAY THROUGH MONDAY/... AS OF 345 AM EDT SATURDAY... STRONG 5H TROF TO THE NW WILL GRADUALLY PROPEL SURFACE COLD FRONT INTO THE OHIO VALLEY SUNDAY BEFORE SLOWING UP IN RESPONSE TO NORTHWARD MOVING TROPICAL STORM LEE ALONG THE GULF COAST. THIS MAY CONFINE THE HIGHEST POPS TO THE FOOTHILLS AND MOUNTAINS THRU SUNDAY AFTERNOON AS UPPER RIDGING BUILDS NORTHEAST OF THE TROPICAL LOW INTO THE MID ATLANTIC PIEDMONT. THIS WOULD SUPPORT STICKING WITH MAINLY CHANCE POPS WEST AND MOSTLY ISOLATED COVERAGE OUT EAST WHERE MAY STAY DRY FOR THE MOST PART. GIVEN A BIT SLOWER ARRIVAL OF CONVECTION AND SW FLOW...WILL STAY ON THE WARM SIDE OF MOS GUIDANCE...ESPCLY EAST WHERE MORE SUN SUPPORTS HIGHS AROUND 90 OR SO. GREATER THREAT OF CLOUDS AND PRECIPITATION FURTHER WEST SHOULD HOLE TEMPERATURES TO THE UPPER 70S TO MID 80S. SURFACE FRONT SHOULD WORK TO ALONG THE WESTERN SLOPES BY EARLY MONDAY BEFORE SINKING SE ACROSS THE CWA DURING MONDAY. THUS EXPECT MAIN CORRIDOR OF SHOWERS TO EDGE SLOWLY SE ACROSS THE REGION ESPCLY FROM LATE SUNDAY NIGHT THRU LATE MONDAY. HOWEVER TIMING OF THIS STILL QUITE IFFY WITH JUST HOW FAST AND FAR NORTH THE REMNANT TROPICAL SYSTEM WILL GET AS IT INTERACTS WITH THE UPPER TROFFINESS. THIS COULD HOLD UP THE BOUNDARY EVEN MORE...KEEPING THE MORE SIG SHRA TO THE WEST THRU MONDAY WITH RAINFALL MORE THE RESULT OF DEVELOPING UPSLOPE SW WITH A SE TRAJECTORY TAKING SHAPE BY LATE MONDAY PER THE GFS. HOWEVER THINK ENOUGH POTENTIAL...AT LEAST FROM THE FRONT...TO PUSH LIKELY POPS ACROSS FROM WEST TO EAST STARTING LATE SUNDAY NIGHT WITH HIGHEST POPS LATE MONDAY AFTERNOON. KEPT HIGHS MAINLY IN THE 70S WEST...TO LOW 80S ACROSS THE PIEDMONT ON MONDAY...BUT COULD ZOOM UP OUT EAST IF CLOUDS/SHRA END UP BEING SLOWER. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... AS OF 200 PM EDT FRIDAY... LOTS OF UNCERTAINTY CONTINUES IN THE EXTENDED IN REGARDS TO EVENTUAL EVOLUTION OF GULF TROPICAL SYSTEM AND INTERACTION WITH RESIDUAL FRONTAL BOUNDARY OVER THE CAROLINAS. LATEST MODELS HAVE TRENDED FURTHER NORTH/NE WITH TRACK OF REMNANT TROPICAL LOW...AND/OR ITS INTERACTION WITH NORTHERN STREAM TROFFINESS CAUSING A CUTOFF LOW JUST WEST OF THE MOUNTAINS BY LATE IN THE WEEK. THIS SCENARIO WOULD PRODUCE A PROLONGED PERIOD OF DEEP TROPICAL S/SE FLOW ACROSS THE LEFTOVER FRONT RESULTING IN BOUTS OF POTENTIAL HEAVY RAIN ESPCLY MONDAY NIGHT INTO WEDNESDAY AS THE DEEPER CORE OF MOISTURE SLIDES NE WELL AHEAD OF THE GULF STATES DEPRESSION. HOWEVER ENSEMBLES SUGGEST MORE OF A EASTWARD TRACK TO THE GULF LOW POSSIBLY ALLOWING MORE DRY AIR TO SINK SOUTH BEHIND THE FRONT WITH THE BEST OVERRUNNING TO THE SOUTH. FOR NOW APPEARS A COMPROMISE OF BOTH SCENARIOS LIKELY BEST WITH THE MAIN CONCERNS BEING HOW FAR NE THE DEEPER TROPICAL RH MAKES IT AND EXACTLY WHERE THE 85H FRONT ENDS UP TO LIKELY SERVE AS THE TRAIN TRACK FOR HEAVY RAIN HEADING NE. IF THIS ENDS UP BEING FARTHER WEST...WHICH HAS BEEN A TREND IN THE PAST...THEN COULD SEE CORRIDOR OF BEST RAIN STAY ALONG THE RIDGES OR JUST WEST SO SOMETHING TO WATCH. OTRW...SINCE WILL HAVE VERY HIGH PWATS AND A POSSIBLE PROLONGED EVENT...WILL CONTINUE TO HIGHLIGHT IN THE HWO OVER THE WEST FOR NOW. THUS WILL LEAN TOWARD THE HIGHER HPC POPS...ESPCLY MON NGT INTO WED...BUT HOLD BACK ON CATEGORICAL FOR NOW GIVEN UNCERTAINTY AND TO AVOID FLIP FLOPPING TO SOME DEGREE. STRONG LOW LEVEL WEDGE SHOULD LIMIT CONVECTION TO MAINLY MONDAY NIGHT AS ONSET OF MORE WIDESPREAD SHOWERS ARRIVE LATE WITH A POSSIBLE CAD EVENT TUE/WED UNDER OVERRUNNING PRECIP. THIS SHOULD KEEP HIGHS MAINLY IN THE 60S TO LOW 70S TUE/WED...AND PERHAPS ONLY UPPER 50S IN SPOTS PENDING RAINFALL/WEDGE. EXPECT LIFT TO GET MORE STRETCHED OUT LATER IN THE WEEK WITH MORE FOCUS WITH DIFFLUENCE ALOFT AHEAD OF THE UPPER LOW...AND IN LEFTOVER DEEP RH NORTHEAST OF THE REMNANT SFC FEATURE LEADING TO MORE SCATTERED NATURE SHRA WITH CHANCE POPS WED NIGHT THRU FRIDAY FOR NOW. HOWEVER...IF RIDGING BETWEEN KATIA OFFSHORE AND THE UPPER INLAND SYSTEM PUSHES WEST A BIT...THEN SHRA WILL BE QUITE A BIT LESS BY THU/FRIDAY WITH DEEPER MOISTURE TO THE WEST. TEMPS SHOULD RECOVER A BIT AS THE WEDGE WEAKENS THU AND FRIDAY...BUT STILL BELOW NORMAL WITH MOST HIGHS IN THE 70S BY WEEKS END. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... AS OF 145 PM EDT SATURDAY... WHILE VFR CONDITIONS HAVE FINALLY RETURNED AT ALL TAF SITES AS OF MIDDAY...BCB WAS LAST FOR FOG/STRATUS TO LIFT...NOW ISOLD TO SCT THUNDERSTORMS ARE FIREING ALONG THE HIGHER RIDGES...AS WELL AS AS A FEW SLIDING DOWN FROM THE NORTHEAST INTO THE CENTRAL VA PIEDMONT AND FOOTHILLS...POSSIBLY REACHING LYH BY 2:30 OR 3PM. PLACED VCTS IN ALL TAFS BUT DAN INTO THE EARLY EVENING...7PM TO 8PM. BIGGEST CONCERN WITH THESE STORMS WILL BE GUSTY WINDS...MAINLY FROM THE NORTH OR NORTHEAST...BUT WILL BE ERRATIC AS USUAL. BRIEF MVFR CONDITIONS IN HEAVY RAIN POSSIBLE...BUT PROBS ARE FAIRLY LOW THAT ANY STORM WILL PASS RIGHT OVER AN AIRPORT. SOME PARTIAL CLEARING TONIGHT...AND WITH WEAK SFC HIGH STILL HAVING SOME INFLUENCE...AREAS OF FOG LIKELY AGAIN TONIGHT...WITH IFR/LIFR CONDITIONS EXPECTED AT TAF SITES WEST OF BLUE RDG DURING EARLY MORNING HOURS. DONT EXPECT THESE CONDITIONS WILL HANG ON QUITE AS LONG AT BCB SUNDAY MORNING AS SW FLOW ALOFT WILL BE INCREASING A BIT AND NOT ANTICIPATING THE STRONG INVERSION A FEW THOUSAND FEET OFF THE GROUND. MORE SCATTERED LATE AFTERNOON OR EVENING SHOWERS AND THUNDERSTORMS ARE EXPECTED SUNDAY AS A COLD FRONT SLOWLY APPROACHES FROM THE WEST. AGAIN...THE BEST COVERAGE OF STORMS WILL BE IN THE MTNS. WIDESPREAD SHOWERS AND STORMS ALONG WITH PERIODS OF MVFR/IFR CONDITIONS ARE NOW LIKELY MONDAY AND TUESDAY...POSSIBLY INTO WEDNESDAY WITH THE FRONT STALLING NEAR THE AREA. POTENTIAL EXISTS FOR TROPICAL MOISTURE TO STREAM NE FROM THE SYSTEM IN THE GULF DURING THIS TIME WHICH COULD BRING SUB VFR AND RAINY CONDITIONS FOR SEVERAL DAYS. && .RNK WATCHES/WARNINGS/ADVISORIES...
