The episode as NWS RNK wrote it up.
Deep moisture and an upper level low, associated with the remnants of Hurricane Isaac, built into the forecast region, providing the fuel for scattered strong to severe thunderstorm activity. Precipitable water values were near 2 inches across the forecast area, which was more than double what is typically found during early September. With abundant moisture and decent instability, slow moving pulse thunderstorm activity developed mainly along and east of the Blue Ridge Mountains from late morning through sunset.
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 2, 11:47 AM EST, 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 1247 PM EDT SUN SEP 2 2012 .SYNOPSIS... THE REMNANTS OF HURRICANE ISAAC WILL IMPACT THE WEATHER ACROSS THE REGION FOR THE NEXT SEVERAL DAYS AS THEY DRIFT FROM THE MIDDLE MISSISSIPPI VALLEY REGION TOWARD THE CENTRAL APPALACHIANS. WITH DEEP TROPICAL MOISTURE LINGERING ACROSS THE REGION...EXPECT WIDESPREAD RAIN AND THUNDERSTORMS WITH LOCALLY HEAVY RAIN THROUGH AT LEAST MID-WEEK UNTIL A FRONTAL SYSTEM ATTEMPTS TO DRY THINGS OUT SOME TOWARD THE END OF THE WEEK. IT WILL ALSO REMAIN WARM AND MUGGY WITH THE TROPICAL MOISTURE FIRMLY ENTRENCHED ACROSS THE AREA. && .NEAR TERM /THROUGH TONIGHT/... AS OF 1238 PM EDT SUNDAY... SCATTERED SHOWERS AND STORMS ARE RAPIDLY DEVELOPING WHERE EARLIER THINKING ANTICIPATED...HOWEVER BY ABOUT ONE HOUR SOONER. HAVE UPDATED THE GRIDS...PRIMARILY POP AND WX...TO ACCOMMODATE FOR THIS AND TWEAK IN TIME THE PROGRESSION OF THIS ACTIVITY THROUGH THE AFTERNOON. ANTICIPATE THAT THE MAIN FOCUS WILL PARALLEL ALONG AND JUST EAST OF THE CREST OF THE BLUE RIDGE. SOME OF THE HEAVIER CELLS MAIN CONTAIN LOCALLY HEAVY RAIN AND GUSTY WINDS. OTHERWISE...NO SIGNIFICANT CHANGES TO REST OF THE FORECAST ELEMENTS THROUGH THE AFTERNOON. AS OF 958 AM EDT SUNDAY... BASED UPON THE LATEST RADAR TRENDS OF KFCX 88D AND NEIGHBORING RADARS...HAVE MADE ADJUSTMENTS TO THE POP AND WX GRIDS THROUGH THE REMAINDER OF THE MORNING INTO THE AFTERNOON. SCATTERED SHOWERS AND STORMS CURRENTLY ARE CONFINED TO THOSE PARTS OF THE AREA NEAR AND NORTH OF I-64. THIS CLUSTER OF ACTIVITY WAS BEING REPRESENTED WELL VIA THE 06Z...2AM...RUN OF OUR LOCAL WRF MODEL. CONCURRENTLY...HAVE WEIGHTED ITS OUTPUT HEAVILY THROUGH THE EARLY AFTERNOON. THIS SOLUTIONS HAS LIMITED PRECIPITATION OUTSIDE OF THE AREA IMMEDIATELY DOWNSTREAM OF THE CURRENT ACTIVITY UNTIL NOON. AT THIS POINT...DAYTIME HEATING STARTS TO HELP IN THE FORMATION OF A GENEROUS COVERAGE OF SHOWERS AND STORMS PARELLEL TO AND ALONG THE CREST OF THE BLUE RIDGE AND EASTWARD INTO THE PIEDMONT. HAVE FOCUSED THE BEST AFTERNOON POPS...LIKELIES...ACROSS THE CENTRAL AND EASTERN PARTS OF THE FORECAST AREA. OTHERWISE...HAVE MADE ONLY MINOR TWEAKS TO HOURLY TEMPERATURES...DEW POINTS...WIND AND SKY COVER BASED UPON THE LATEST OBSERVATIONS AND EXPECTED TRENDS INTO THE EARLY AFTERNOON. AS OF 755 AM EDT SUNDAY... JUST MADE SOME MINOR TWEAKS TO THE POPS/WX/T/TD GRIDS DURING THE FIRST 6 HOURS...OTHERWISE NO SIGNIFICANT CHANGES AT THIS TIME. THERE ARE PATCHY AREAS OF DENSE FOG...BUT THIS WILL DISSIPATE QUICKLY ENOUGH THAT IT WAS NOT ADDED TO THE ZONES AT THIS TIME. FORECAST BASICALLY APPEARS ON TRACK AT THIS TIME. AS OF 445 AM EDT SUNDAY... THE REMNANTS OF HURRICANE ISAAC WILL CONTINUE TO BE THE PRIMARY WEATHER MAKER FOR OUR CWA DURING THE PERIOD AS THEY DRIFT SLOWLY FROM THE WESTERN TN/MID-MS VALLEY REGION. PWS WILL CONTINUE TO INCREASE TO NEAR 2.0 INCHES DURING THE PERIOD. THE ASSOCIATED UPPER LOW WILL DRIFT TOWARD THE SOUTHERN APPALACHIANS AND THEN SINK SOUTH BY TUE INTO THE SE STATES. THE REMNANT LOW CENTER OF ISAAC WILL DRIFT TOWARD THE NE STATES...HENCE DEVELOPING A SPLIT BETWEEN THE UPPER LOW AND THE REMNANT SFC LOW. EXACTLY HOW THIS IMPACTS THE CWA IN TERMS OF PCPN REMAINS TO BE SEEN. THE MAIN FEATURES TO WATCH DURING THE SHORT TERM FOR PCPN FOCUS WILL BE...A PERSISTENT NW-SE BAND OF CONVERGENCE FROM NORTHERN WV TOWARD EAST CENTRAL VA...ROUGHLY FROM EKN TO RIC...ESSENTIALLY DENOTING A PSEUDO/VERY WEAK BACK DOOR FRONT SUPPORTED BY A DEEP NE U.S. TROUGH...REMNANT FEEDER BANDS OF ISAAC NOW BEGINNING TO MOVE INTO THE CWA...AND THE CORE REMNANTS OF ISAAC...EXPECTED TO REMAIN ACROSS MIDDLE KY/TN THROUGH THE NEAR TERM. HENCE...THERE REMAIN MANY UNCERTAINTIES WITH REGARD TO EXTENT...AMOUNT...AND TIMING OF PCPN. NONETHELESS...ALL MODELS CONTINUE TO INDICATE WIDESPREAD PCPN ACROSS THE CWA...WITH THE MOST LIKELY AREA REMAINING ACROSS AREAS FROM EKN-RIC...IMPACTING OUR NORTHERN COUNTIES. IN THESE COUNTIES I HAVE ADVERTISED CATEGORICAL POPS...WITH CHC TO HIGH CHC POPS ELSEWHERE. GFS ADVERTISES VERY IMPRESSIVE INSTABILITY ACROSS THE CWA 18Z-00Z TODAY...WITH EVEN MODEST SHEAR NOTED NEAR THE ABOVE NOTED BOUNDARY. HENCE...HAVE INCLUDED TSRA ALL AREAS FROM LATE MORNING ON AS WELL AS A MENTION OF LOCALLY HEAVY RAIN GIVEN THE INCREASING PWS/TROPICAL AIR MASS IN PLACE. SPC DOES NOT CURRENTLY HAVE US OUTLOOKED FOR SEVERE...BUT CANNOT RULE OUT ISOLD WET DOWNBURSTS...SUCH AS OCCURRED SAT AFTERNOON. WITH RESPECT TO RAINFALL CONCERNS...THE AREA REMAINS IN A MILD DROUGHT. ALTHOUGH LOCALLY HEAVY DOWNPOURS MAY OCCUR...AT LEAST DURING THE NEXT 24 HOURS...OVERALL RAINFALL SHOULD NOT BE SUFFICIENT TO PRODUCE OTHER THAN VERY LOCALIZED FLASH FLOODING...IF AT ALL. THIS WOULD MAINLY BE IF SUCH RAINFALL OCCURRED IN URBAN AREAS. THUS...A FFA IS NOT NEEDED AT THIS TIME. THIS WILL BE AN INCREASING CONCERN INTO THE SHORT TERM PERIODS AS REMNANT ISAAC RAINFALL CONTINUES ACROSS THE CWA ON A DAILY BASIS THROUGH MID-WEEK. TEMPERATURES WILL CHANGE LITTLE DURING THE NEAR TERM AND INTO THE SHORT TERM. TROPICAL AIR MASS AND 850MB TEMPS STUCK NEAR +18C WILL RESULT IN LITTLE TO NO DAY-TO-DAY CHANGE IN MAX/MIN TEMPS. MIN TEMPS WILL BE WELL ABOVE NORMAL AND COOL LITTLE AT NIGHT...REMAINING IN THE LOW TO MID 70S ACROSS THE PIEDMONT REGION...WITH 60S MOUNTAINS. MAX TEMPS WILL DROP A LITTLE FROM RECENT DAYS BECAUSE OF CLOUD COVER AND MORE SHRA/TSRA ACTIVITY...BUT REMAIN A GOOD 5+ DEGREES ABOVE NORMAL MAX VALUES FOR THIS TIME OF YEAR...WITH READINGS IN THE LOW 90S STILL POSSIBLE ACROSS THE VA/NC PIEDMONT REGION. && .SHORT TERM /MONDAY THROUGH TUESDAY/... AS OF 242 AM EDT SUNDAY... REMNANTS OF ISAAC REMAINING INTACT AS IT DRIFTS SOUTHEAST OVER THE SOUTHERN OHIO VALLEY MONDAY. WEAK SHORT WAVES WILL MOVE OVER THE AREA AND AHEAD OF ISAAC MONDAY AND MONDAY NIGHT TO KEEP HIGH POPS IN THE FORECAST. STEERING FLOW REMAINS WEAK AND WITH PWATS RUNNING 2 STANDARD DEVIATIONS ABOVE NORMAL...HEAVY RAIN WILL ACCOMPANY MOST STORMS. WITH THE SLOW MOVEMENT OF STORMS...LOCALIZED FLASH FLOODING IS POSSIBLE...ESPECIALLY IN AREAS SEEING RAIN OVER THE WEEKEND. INTERESTING TWIST WITH REMNANTS OF ISAAC ON TUESDAY. SEVERAL MODELS SPLIT THE SYSTEM IN HALF WITH THE LOW LEVEL ENERGY MOVING NORTHEAST ACROSS THE MID ATLANTIC AND MID LEVEL FLOW HEADING SOUTHEAST OVER THE SOUTHEASTERN UNITED STATES. THE UPPER LEVEL FLOW CONTINUES TO DRIFT EASTWARD WITH THE LOW OPENING UP INTO A POSITIVE TILTED TROUGH. IF THIS HAPPENS...BULK OF THE SHOWERS WILL BE NORTHEAST AND SOUTH OF THE AREA. WE WILL STILL SEE SHOWERS AND THUNDERSTORMS IN THE REGION BUT THEY WILL BE MORE SCATTERED THAN WIDESPREAD. THE AREA WILL ALSO REMAIN IN A TROPICAL-LIKE AIR MASS WITH HEAVY RAIN ACCOMPANYING SLOW MOVING STORMS. PWATS AGAIN RUNNING 2 STANDARD DEVIATIONS ABOVE NORMAL. CLOUDS...RAIN AND EASTERLY FLOW WILL HAVE AFTERNOON TEMPERATURES RUNNING CLOSE TO NORMAL. OVERNIGHT LOW WILL BE MUGGY WITH SOME WARM MINIMUM RECORDS BEING THREATEN INTO MONDAY NIGHT AND TUESDAY NIGHT. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... AS OF 1230 PM EDT SATURDAY... TROPICAL MOISTURE WILL REMAIN IN PLACE ACROSS THE MID ATLANTIC INTO AT LEAST MID WEEK BUT SHOULD SEE A GRADUAL DRYING TREND STARTING LATER THURSDAY AND LASTING INTO NEXT WEEKEND. MAIN CONCERN EARLY ON WITH THE ISAAC REMNANT AS IT SEPARATES...WITH THE LOW LEVEL SURFACE WAVE HEADING THRU THE OHIO VALLEY AND POINTS EAST BY WEDNESDAY...WHILE THE MID LEVEL SUPPORT DETACHES AND GETS BLOCKED...SLIDING BY JUST TO OUR SW BEFORE FADING. THIS MAY ACT TO SLOW DOWN THE EXODUS OF THE ASSOCIATED BOUNDARY AS WELL WITH IT LINGERING ACROSS THE REGION TUESDAY NIGHT INTO WEDNESDAY. MODELS SUGGEST VERY HIGH PWATS AND STRONG SOUTHERLY MOISTURE TRANSPORT AROUND THE RESIDUAL VORT AXIS DURING THE MID WEEK PERIOD SO RUNNING WITH DECENT CHANCE POPS TUE NIGHT...AND HIGH CHANCE TO LIKELYS WED...PER HEATING OF TROPICAL JUICE ALONG THE LEFTOVER SURFACE BOUNDARY. THIS COULD ALSO LEAD TO A HIGH LIKELIHOOD OF HEAVY RAIN A BIT LONGER SO KEEPING IDEA AS SUGGESTED IN THE HWO. APPROACH OF THE NEXT NRN STREAM S/W TROF AND ITS ASSOCIATED COLD FRONT SHOULD FINALLY ACT AS A KICKER THURSDAY WITH THIS BOUNDARY PUSHING DEEPER MOISTURE TO THE EAST BY THURSDAY AFTERNOON. LEFT IN SOME CHANCE POPS SE AND NW SECTIONS THURSDAY BUT WITH OVERALL NW TRAJECTORY THINK COULD BE ONLY ISOLATED COVERAGE. MODELS PUSH THIS NEXT FRONT TO THE EAST OF THE AREA FRIDAY WITH WEAK HIGH PRESSURE BUILDING IN FROM THE NW SATURDAY BRINGING A TASTE OF DRIER AIR BY SATURDAY. HOWEVER GIVEN THE MAIN 5H TROF WELL NORTH AND A FLAT FLOW IN PLACE...LEAVING IN A LOW POP MENTION FOR FRIDAY GIVEN THE POTENTIAL FOR THE DRIER AIR TO BE A BIT SLOWER THAN PROGGED. TEMPS TO REMAIN PRETTY MUCH STATUS QUO INTO THURSDAY...WITH WARM/MUGGY NIGHTS...AND HUMID DAYS WITH HIGHS MAINLY IN THE 80S. PASSAGE OF FRONT SHOULD START TO KNOCK BACK HUMIDITY LEVELS FRIDAY AS WELL AS TEMPS OUT WEST AND ACROSS THE REGION BY SAT WHEN WILL ONLY SEE THE EAST CLIMB INTO THE 80S WHILE THE MOUNTAINS STAY IN THE 70S. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... AS OF 740 AM EDT SUNDAY... TROPICAL AIR MASS AND LIGHT WINDS HAVE RESULTED IN MORE WIDESPREAD FG THAN EARLIER EXPECTED. LWB/BCB HAVE HAD LIFR CIGS/VSBYS LAST COUPLE OF HOURS. HOWEVER...IMPROVEMENT TO MVFR/VFR SHOULD BE FAIRLY QUICK WITHIN THE NEXT COUPLE OF HOURS. OTHER SITES HAVE REMAINED VFR THROUGHOUT THE NIGHT AND AT THIS POINT SHOULD REMAIN SO. OTHERWISE LAYERED MID/HIGH CLOUDS CONTINUE WITH PATCHY -RA/-SHRA PERSISTING THROUGHOUT MOST OF THE CWA. HEAVIER SHRA/TSRA HAVE BEEN CONFINED TO CONVERGENT AREA ALONG BACKDOOR FRONT JUST NORTH OF THE CWA BORDER FROM EKN-SHD-RIC. EXPECT -RA/-SHRA TO PERSIST UNTIL MID DAY WITH LAYERED MID CLOUDS...THEN MODELS SUGGEST HEATING WILL BE MORE THAN SUFFICIENT TO GET SCT TSRA GOING AT MOST TAF SITES IN THE 18Z-20Z TIME FRAME. THERE MAY BE MORE OF A DELAY IN INITIATION OF CONVECTION FOR DAN. INSTABILITY IS QUITE IMPRESSIVE ACROSS THE CWA TODAY AND WITH PWS NEARING 2.0 INCHES...EXPECT SOME PRETTY HEALTHY TSRA MID TO LATER AFTERNOON IF ENOUGH HEATING CAN BE REALIZED. WINDS TRANSITION TO SSW-SE 5-7KTS THROUGH TAF VALID PERIOD...EXCEPT WV SITES...WHERE DIRECTION CHAOTIC. THESE SE WINDS WILL RESULT IN UPSLOPE FLOW ALONG THE BLUE RIDGE AND LIKELY IFR-LIFR CIGS/VSBYS ROA-LYH AFT 08Z...ESPECIALLY IN LIGHT OF WET GROUND EXPECTED TO BE IN PLACE AT THAT TIME. THE USUAL PROBLEMS WITH LIFR CIGS/VSBYS CAN ALSO BE EXPECTED AT BLF/LWB/BCB AFT 08Z SUN...WHICH MAY ALSO BEGIN SOONER THAN NORMAL WITH WET GROUND IN PLACE. AS OF 200 AM EDT SUNDAY... VFR CIGS AND VFR-MVFR VSBYS WILL DOMINATE MUCH OF THE TAF VALID PERIOD AS THE REMNANTS OF ISAAC CONTINUE TO SPREAD TOWARD THE CWA FROM THE MID MS/TN VALLEY REGION. LAYERS OF MID/HIGH CLOUDS...TYPICAL OF A TROPICAL ENVIRONMENT...WILL REMAIN IN PLACE. WIDESPREAD -RA/SPRINKLES NOTED THROUGHOUT MOST OF THE CWA...SO THIS HAS BEEN ADDED TO THE TAFS OVERNIGHT/EARLY SUN. WITH DAYTIME HEATING...EXPECT MORE SHRA AND EVEN TSRA AFT 18Z. WILL DROP MENTION OF TSRA AFT 02Z. ENVIRONMENT NOT CONDUCIVE TO RADIATIONAL FOG DEVELOPMENT AT ALL...BUT AREAS IN/NEAR WHERE HEAVIER RAIN FELL LATE SAT MAY SEE DEVELOPMENT OF IFR-LIFR CIGS/VSBYS LATE TONIGHT/EARLY SUN. THIS SHOULD BE QUITE LOCALIZED AND QUESTIONABLE GIVEN EXTENT OF MID/HIGH CLOUDS. A SOUTHERLY FLOW EXPECTED TO DEVELOP AFT 14Z MOST TAF SITES AS THE CIRCULATION REMNANTS OF ISAAC DRIFT CLOSER AND BEGIN TO AFFECT THE WIND FIELD ACROSS THE REGION. SPEEDS REMAINING LESS THAN 10KTS THROUGH TAF VALID PERIOD. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...NONE. NC...NONE.
