The episode as NWS RNK wrote it up.
A weakening complex of thunderstorms moved across northwest North Carolina during the evening hours of the 21st. The system was still strong enough to produce widespread wind damage in Surry County before it dissipated when entering the Piedmont.
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 Jun 21, 4:17 PM EST, 2 hours 10 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE BLACKSBURG VA 517 PM EDT MON JUN 21 2010 .SYNOPSIS... A STRONG HIGH PRESSURE ALOFT WILL MAINTAIN ITS GRIP OVER MUCH OF THE SOUTHERN HALF OF THE NATION FOR THE NEXT SEVERAL DAYS. THIS WILL KEEP THE FORECAST AREA HOT AND MAINLY DRY. HOWEVER...THE UPPER RIDGE IS EXPECTED TO GRADUALLY WEAKEN THROUGH THE WEEK...ALLOWING AN INCREASING CHANCE FOR A COOL FRONT AND ASSOCIATED SHOWER AND THUNDERSTORM ACTIVITY TO AFFECT THE REGION. && .NEAR TERM /THROUGH TUESDAY/... QUICK UPDATE TO RAISE POPS TO HIGH CHANCE ACROSS SE WVA AND FAR WESTERN VA FOR LEADING EDGE OF MCS APPROACHING FROM THE NW. ALTHO MESO ANALYSIS SHOWS FADING SUPPORT...MOMENTUM AND COLD POOL ALOFT LIKELY TO KEEP THE BAND OF STORMS GOING A BIT LONGER. ALSO OUTFLOW MAY DEVELOP STRONGER CELLS AHEAD OF THE MAIN BAND SO MAY HAVE TO EXTEND POPS FARTHER SE INTO NW NC IF TRENDS CONTINUE. PREVIOUS DISCUSSION BELOW... MAIN FCST ISSUE IN THE SHORT TERM IS THE UPSTREAM MCS MOVG INTO ERN KY AT THIS TIME. THE MEAN WIND FAVORS BRINGING THE SHOWERS/TSTMS INTO THE FAR WESTERN CWA...WHILE THE STRONGEST INSTABILITY REMAINS WELL WEST OF THE CWA. THE 12Z OP NAM BRINGS THE CONVECTION TO THE SW MTNS OF VA AND NRN MTNS OF NC...AND SO DOES OUR LOCAL 15Z RUN WRF-ARW MODEL...IN THE 6 PM TO 900 PM TIME FRAME. THE AIRMASS REMAINS VERY WARM AND FAIRLY DRY OVER MOST OF THE CWA. HAVE DECIDED TO ADD IN A SLIGHT CHC POP AT THIS TIME... THINKING THAT THE CONVECTION WILL LIKELY STAY WEST OF THE CWA WITH THE BETTER INSTABILITY. SHOULD BE ANOTHER WARM NIGHT...BUT WITH DECENT RADIATIONAL COOLING...SO HAVE KEPT LOWS CLOSER TO THE COOLER MAV GUIDANCE AND ADDED IN FOG TO THE MTN VALLEYS. FOR TUESDAY...THE AIRMASS BECOMES MORE UNSTABLE IN THE WAKE OF THIS EVENINGS MCS. THE WARMER TEMPS AROUND 700 MBS DROP SOME AND WE LOSE OUR STRONG MID LEVEL CAP. LOW LEVEL FLOW REMAIN WEAK...BUT IS WESTERLY INTO THE MTNS...AND SOUTH OR SOUTHWEST EAST OF THE MTNS...PROVIDING SOME CONVERGENCE ALONG THE BLUE RIDGE. IN ADDITION...ALL MODELS HAVE A SHORT WAVE MOVG THRU THE OHIO VALLEY AND CENTRAL APPLNS TUE AFTERNOON...AND THE TAIL END OF THIS FEATURE MAY HELP ORGANIZE TSTMS ACROSS THE NRN CWA. HAVE RAISED POPS TO LOW CHC FOR TUE AFT FROM THE BLUE RIDGE WESTWARD INTO THE MTNS. WILL BE ANOTHER HOT DAY...WITH TEMPS EVEN WARMER THAN TODAY. GUIDANCE SUGGESTS BLF BLF WILL HAVE A GOOD CHC TO REACH 90...WHICH WOULD TIE THEIR RECORD. ALL OTHER RECORDS LOOK OUT OF REACH. SEE CLIMATE SECTION BELOW FOR RECORD HIGHS TUE. FINALLY...WILL ISSUE AN AIR QUALITY ALERT FOR THE NE PIEDMONT OF NC FOR TUE. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... SHORTWAVE GOES BY JUST NORTH OF THE COUNTY WARNING AREA WHICH WILL RESULT IN LINGERING SHOWERS/THUNDERSTORMS FOR SOUTHEAST WEST VIRGINIA AND THE ALLEGHANY HIGHLANDS TUESDAY NIGHT. AT THIS TIME...HAVE MAINTAINED THE SLIGHT CHANCE POPS EARLY TUESDAY NIGHT AS EXPECT THE COVERAGE AREA TO STAY SMALL. PRECIP CHANCES WILL INCREASE THROUGH THURSDAY AFTERNOON TO LATE EVENING AS A SHORTWAVE TROUGH APPROACHES THE AREA. WILL HAVE MAINLY AFTERNOON AND EVENING ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS MAINLY ACROSS THE MOUNTAINOUS AREAS THROUGH WEDNESDAY WITH GREATER COVERAGE FOR THURSDAY. MAX TEMPERATURES EACH DAY WILL BE MAINLY THE MID TO UPPER 80S IN THE MOUNTAINS AND LOW TO MID 90S EAST OF THE BLUE RIDGE. LOWS WILL RANGE FROM THE LOW TO MID 60S WEST TO UPPER 60S TO NEAR 70 EAST. && .LONG TERM /FRIDAY THROUGH MONDAY/... CLOSED UPPER LOW SLOWLY PUSHES EAST BUT BEGINS TO BREAK DOWN BY LATE WEEK AS MORE SHORTWAVE ENERGY CROSSES THE GREAT LAKES. THIS WILL ALLOW A COLD FRONT TO PUSH TOWARDS THE FORECAST AREA. VERY LITTLE CHANGES TO THE LONG TERM FORECAST AS THE MODELS CONTINUE TO DISAGREE ON STRENGTH AND TIMING OF THE COLD FRONT. CONTINUE VARYING SLIGHT CHANCE TO CHANCE POPS EACH DAY THROUGH THE WEEKEND. PWATS ARE STILL PROGGED TO BE CLOSE TO 2 INCHES AND AT THIS TIME...EXPECT BEST CONVECTION TO BE AROUND THE FRIDAY AFTERNOON TIME FRAME. TEMPERATURES WILL REMAIN ABOVE SEASONAL NORMS THROUGH THE PERIOD. && .AVIATION /21Z MONDAY THROUGH SATURDAY/... HIGH PRESSURE AT THE SURFACE AND LOFT WILL BRING LIGHT SFC WINDS AND SCT TO OCNL BKN CLOUDS THIS AFTERNOON- ANY CIGS >4000 FT. WITH LIGHT WINDS AND MOSTLY CLEAR SKIES TONIGHT...THINK THERE WILL BE FAIRLY WIDESPREAD GROUND FOG...WHICH WILL LIKELY BRING MVFR VSBYS TO ALL TAF SITES EXCEPT FOR ROA. LWB WILL LIKELY SEE VLIFR RIVER FOG. FOG SHOULD BE SHALLOW ENOUGH THAT IT WILL LIFT BY 13 OR 14Z. BEYOND 24 HOURS...PREDOMINANTLY VFR WEATHER WITH UNRESTRICTED CONDITIONS ARE EXPECTED AT ALL BLACKSBURG TERMINAL FORECAST SITES (KROA...KLYH...KDAN...KBLF...KLWB) THROUGH THE UPCOMING WEEK...WITH THE EXCEPTION OF A BRIEF PERIOD OF LOCALIZED LATE NIGHT/EARLY MORNING FOG. IN ADDITION...THERE WILL ALSO BE A LOW THREAT FOR BRIEF RESTRICTIONS IN VICINITY OF ISOLATED TO SCATTERED MAINLY DIURNALLY DRIVEN SHOWERS/THUNDERSTORMS THROUGH THE PERIOD. && .CLIMATE...
