The episode as NWS RNK wrote it up.
Broad west-northwest flow aloft was present across the region on the northeast side of a strong subtropical upper ridge centered over the southern plains. Weak disturbances were embedded within the flow aloft. Although the air mass across the region was not as moist as it had been in previous days around the 1st of the month, precipitable water values across the Piedmont were still near 2.0 inches. Only isolated thunderstorms were noted with this event, but given the very saturated conditions from a persistent very wet summer, strong, slow moving thunderstorms across the urban Roanoke area resulted in flood problems once again.
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 Aug 6, 2:30 PM EST, 4 hours 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 330 PM EDT TUE AUG 6 2013 .SYNOPSIS... HIGH PRESSURE MOVES OFF THE COAST TONIGHT. A FRONTAL BOUNDARY AND UPPER DISTURBANCES AFFECT OUR WEATHER FROM WEDNESDAY THROUGH THE END OF THE WEEKEND. && .NEAR TERM /THROUGH WEDNESDAY/... AS 325 PM EDT TUESDAY... LIMITED HEATING ALONG WITH LOW LEVEL CONVERGENCE MAY CREATE ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORM THIS AFTERNOON INTO TONIGHT. THE BEST OF CHANCE OF CONVECTION IS ALONG AND EAST OF THE BLUE RIDGE UNTIL SUNSET. THE WESTERLY WIND AND AMPLE CLOUD COVER ARE HINDERING CONVECTION DEVELOPMENT. THIS EVENING INTO TONIGHT...ANY SHOWERS AND THUNDERSTORMS FADE THOUGH SE TO SOUTH FLOW ALONG WITH PLENTY OF LOW LEVEL MOISTURE MAY KEEP THE SLIGHT CHANCE OF SHOWERS AROUND ALL NIGHT...WITH CHANCES INCREASING OVER THE WEST LATE AS NEXT UPSTREAM SHORTWAVE MOVES TOWARD THE MOUNTAINS. PLAYED LOW TEMPERATURES TONIGHT CLOSE TO WARMER MET GUID WITH READINGS FROM THE LOWER 60S IN THE MOUNTAINS TO AROUND 70 DEGREES IN THE SOUTHEAST. GFS...NAM AND ECMWF ARE CONTINUING THE SLOWER ONSET TREND WITH MIDLEVEL WAVES WEDNESDAY...AND THUS TRIMMED POPS AND SLOWED THE ADVANCE OF CONVECTION. RICH MOISTURE ARRIVES WEDNESDAY BEHIND A WEAK WARM FRONT...AS A COLD FRONT APPROACHES FROM THE NORTHWEST. KEPT THE HIGHEST POPS IN THE WEST WEDNESDAY AND ALLOWED THE MENTION OF HEAVY RAIN WITH STORMS BECAUSE SOME OF THE SHOWERS AND THUNDERSTORMS COULD BE EFFICIENT RAIN PRODUCERS GIVEN THE HIGHER PWAT. AT THIS TIME...NOT EXPECTING ANY WIDESPREAD FLOODING PROBLEMS. WITH RECENT DRIER CONDITIONS... 1 HOUR RFC FFG HAVE CLIMB TO 1.7 TO 3 INCHES. THE SEVERE THREAT REMAINS TO THE NORTH OF THE OHIO RIVER WHERE SPC HAS SLIGHT RISK ON DAY TWO CONVECTIVE OUTLOOK WITH BEST DYNAMICS. WENT WITH COOLER MOS HIGHS ON WEDNESDAY FROM THE LOWER 70S IN THE MOUNTAINS TO THE LOWER 80S IN THE SOUTHEAST. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/... AS OF 300 PM EDT MONDAY... WILL MAINTAIN HIGHER LIKELY POPS ACROSS THE NW INTO WED EVENING WITH MOSTLY CHANCE COVERAGE ELSW AS THE EARLIER DAMPENING VORT LOBE PASSES ACROSS FROM THE WEST. OTRW PC AND MUGGY WED NIGHT WITH ANY LEFTOVER SHRA FADING IN ALL EXCEPT THE MOUNTAINS BY MORNING. 5H HEIGHTS THEN LOOK TO BUILD A BIT ON THU IN RESPONSE TO BACKING FLOW ALOFT AHEAD OF THE NEXT SHORTWAVE APPROACHING FROM THE NW. HOWEVER MAIN LIFT WITH THIS FEATURE LIKELY TO STAY TO THE WEST/NW CLOSER TO THE UPPER TROF AND ASSOCIATED COLD FRONT ALONG A RIBBON OF DEEPER MOISTURE FROM THE SRN MIDWEST INTO THE OHIO VALLEY. SOME OF THIS SHRA/TSRA WITHIN THIS CORRIDOR MAY SPILL SE AFFECTING MAINLY THE FAR NW SECTIONS THU AND MORESO WESTERN HALF FRIDAY AS A BETTER DEFINED PRE-FRONTAL BAND DEVELOPS. WEAK IMPULSES WITHIN THIS HIGHER PWAT BAND TO THE NW COULD ALSO CAUSE MCS COMPLEXES AS WELL WHICH MAY INTERUPT THE OVERALL CHAIN OF SHRA/TSRA MAKING EASTWARD EXTENT OF POPS IFFY AS SEEN IN DIFFERENCES BETWEEN THE WETTER GFS AND OTHER LAGGING SOLUTIONS WHICH HOLD MOST ORGANIZED SHRA TO THE NORTH/WEST. OTRW LOOKING AT BETTER SW FLOW TO POSSIBLY CAUSE SOME INCREASE IN TSRA ALONG THE BLUE RIDGE THU...AND IN A WIDER CORRIDOR MOUNTAINS FRI SO KEPT LIKELY POPS THERE INTO THE WESTERN SLOPES AND CHANCE ELSW. HEAVY RAIN AGAIN POSSIBLE BUT KEPT OUT MENTION GIVEN SLOWER MODEL TRENDS IN HAVING WIDESPREAD COVERAGE OF LATE. WITH POTENTIAL IN SEEING MORE INSOLATION ESPCLY EAST GIVEN SLOWER SOLUTIONS...BUMPED UP HIGHS A CAT OR SO MOST SPOTS WHICH WILL PUSH TEMPS CLOSE TO 90ISH PIEDMONT...AND INTO THE 80S ELSW OUTSIDE OF THE HIGHER ELEVATIONS. && .LONG TERM /SATURDAY THROUGH TUESDAY/... AS OF 1140 AM EDT TUESDAY... LOTS OF UNCERTAINTY REMAINS IN THE EXTENDED IN REGARDS TO TIMING OF THE COLD FRONT DROPPING IN FROM THE NORTH THIS WEEKEND AND JUST HOW FAR SOUTH THE BOUNDARY GETS EARLY NEXT WEEK. LATEST MODELS HAVE GOTTEN SLOWER WITH THE EVOLUTION OF THE HUDSON BAY UPPER LOW IN TURN KEEPING A STRONGER/ZONAL 5H TRAJECTORY ACROSS THE MID ATLANTIC A BIT LONGER. THIS COMBINED WITH RIPPLES OF ENERGY SLIDING EAST AND PARALLEL WESTERLY FLOW TO THE FRONT...MAY KEEP THE BOUNDARY STUCK CLOSER TO THE OHIO RIVER EARLY SATURDAY BEFORE CONVECTION... INCLUDING A PASSING WAVE FORCE IT SOUTH OF THE AREA LATER IN THE WEEKEND. THIS WOULD PUT THE AXIS OF DEEPER MOISTURE AND BEST PRE- FRONTAL LIFT ACROSS THE AREA SAT AFTERNOON/EVENING AND MAINLY OVER THE SOUTHERN/EASTERN SECTIONS SUNDAY AT THIS POINT. THUS WILL GO CLOSER TO THE HIGHER WPC LIKELY POPS LATER SATURDAY WITH A SCATTERING OF CONVECTION SUNDAY AFTERNOON. GIVEN TRENDS OF A SLOWER FRONTAL ARRIVAL...EXPECT MUCH WARMER TEMPS SAT PER WEAK COMPRESSION AND MORE HEATING WITH 80S MOST SPOTS AND LOWER 90S SE. FRONT SHOULD DRIFT TO THE SOUTH AND DISSIPATE EARLY NEXT WEEK WITH POTENTIAL FOR ANOTHER WAVE ALOFT TO DROP SE AND LIFT MOISTURE BACK NORTH BY LATER MONDAY INTO TUESDAY. HOWEVER THIS QUITE LOW CONFIDENCE ESPCLY GIVEN DRIER EC SOLNS WHICH SPILLS WEAK RIDGING IN FROM THE NORTH EARLY ON WITH ANY SECONDARY SURFACE LOW WELL OFFSHORE. THEREFORE WILL GO WITH LOW CHANCE POPS MAINLY SOUTH/WEST BOTH DAYS...WITH MORE SUN POSSIBLE BUT TEMPS CLOSER TO NORMAL BEHIND THE BOUNDARY AND UNDER CLOUDS/NE FLOW. && .AVIATION /20Z TUESDAY THROUGH SUNDAY/... AS OF 140 PM EDT TUESDAY... SCT TO BKN MVFR CIGS WITH ISOLATED TO SCATTERED CONVECTION THIS AFTERNOON INTO THIS EVENING. CLOUD COVER FROM THIS MORNING AND CAP IS HINDERING CONVECTION DEVELOPMENT THIS AFTERNOON. MESOSCALE MODELS STILL POINT TO THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS ALONG AND EAST THE BLUE RIDGE MOUNTAINS. DURING THE NEXT COUPLE OF HOURS MAY SEE SOME CONVECTION FORM FROM THE ROANOKE VALLEY NORTHWARD TO THE SOUTHERN SHENADOAH VALLEY. WILL ALLOW FOR VCTS AT ROA...BUT WEST CUTTING CONVECTION. IT SEEMS LIKE THE BEST LOW LEVEL MOISTURE CONVERGENCE AND INSTABLITY IS LOCATED ALONG THE SOUTHERN BLUE RIDGE. THIS EVENING INTO TONIGHT...ANY CONVECTION WILL DIMINISH AS THE SHORTWAVE EXITS EAST AND LOSS OF HEATING OCCURS...ALTHOUGH CANNOT RULE OUT SHOWERS MAINLY NORTH OF A LYH/LWB LINE. THIS IS THE AREA HIGHLIGHTED ON NAM AND GFS TONIGHT. OVERALL KEEPING IT VFR THEN DROPPING CIGS AND SOME VSBYS DOWN TO MVFR/IFR. IT WILL BE DEPENDENT ON RAINFALL THIS AFTERNOON AND HOW MUCH IF ANY CLEARING TAKES PLACE TONIGHT. LWB HAS THE BEST CHANCE FOR FOG OVERNIGHT INTO WEDNESDAY MORNING. THE PATTERN WILL BE ACTIVE WED-SUN WITH A FRONT SAGGING SE TOWARD THE AREA BY THURSDAY-FRIDAY. WILL SEE OFF AND ON SHOWERS AND STORMS MAINLY IN THE AFTERNOON/EVENING WED...WITH OVERNIGHT POSSIBILITIES INCREASING WITH THE FRONT THU-SUN.
