The episode as NWS RNK wrote it up.
A relatively strong cold front, for August, was moving southward through the area as a large area of Canadian High Pressure moved southward through the Great Lakes. |Unstable northwest flow aloft remained over the area on the east side of a strong subtropical ridge located across the Midwest. Scattered thunderstorms developed during the afternoon, especially across the Piedmont, along the southward moving west-east oriented frontal boundary. A few of these became strong to severe and produced damaging wind gusts.
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 23, 2:56 PM EST, 2 hours 24 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 356 PM EDT FRI AUG 23 2013 .SYNOPSIS... DRIER AND SOMEWHAT COOLER HIGH PRESSURE WILL SETTLE OVER THE AREA BEHIND A COOL FRONT TONIGHT AND INTO THE WEEKEND. MOISTURE WILL BEGIN TO VERY SLOWLY RETURN TO THE REGION THROUGHOUT NEXT WEEK. && .NEAR TERM /THROUGH SATURDAY/... AS OF 342 PM EDT FRIDAY... THE COLD FRONT CONTINUES TO MARCH TOWARDS THE AREA LATE THIS AFTERNOON AND WILL SLOWLY MOVE SOUTH OF THE AREA TONIGHT. AREAS THAT SAW RAIN EARLIER TODAY...SE WV-EXTREME SW VA...ARE STILL BEHIND THE THETA-E/DEW POINT BOUNDARY. THIS BOUNDARY JUST MOVED SOUTH OF PITTSBURGH PA AT 300 PM. THE COMBINATION OF MOISTURE AND HEATING WILL KEEP NON-SEVERE SCATTERED CONVECTION OVER THE WEST UNTIL EARLY THIS EVENING. THE STRONGER CONVECTION IS CURRENTLY MOVING ACROSS THE SOUTHERN SHENANDOAH/ROANOKE VALLEYS AND SOUTH-CENTRAL VIRGINIA PIEDMONT THIS AFTERNOON. THIS CONVECTION WILL WORK ITS WAY SOUTH TO THE NC/VA BORDER THIS EVENING. THE PIEDMONT HAS SEEN MORE HEATING TODAY AND SCATTERED STRONG TO ISOLATED SEVERE STORMS ARE POSSIBLE THROUGH 10 PM. THIS STRONGER CONVECTION IS MOVING TO THE SOUTHEAST AROUND 20 MPH WITH RAINFALL RATES OF 3 TO 5 INCHES PER HOUR. IF THESE STORMS SLOW DOWN AND MAINTAIN THESE RAINFALL RATES...STREET FLOODING WILL LIKELY RESULT. ALL MODELS SHOWING VIABLE SOLUTIONS FOR THIS EVENING WITH KEEPING SHOWERS AND THUNDERSTORMS ACROSS THE SOUTHEAST CORNER OF RNK CWA THROUGH MIDNIGHT. I FAVORED AND BLENDED THE 12Z NAM AND 16Z HRRR. THESE MODELS CAPTURED CURRENT SHOWERS OVER THE AREA AT THE TIME. ONCE THE SHOWERS EXIT...THE THETA-E BOUNDARY WILL REMAIN OVER THE AREA. WITH A MOIST SOUTHEAST FLOW...LOW LEVEL CLOUDS AND POSSIBLE DRIZZLE SHOULD REMAIN INTO SATURDAY MORNING. DRY AIR BY MID MORNING WILL QUICKLY CLEAR THE SKIES BY THE AFTERNOON. ALSO WITH LOW CLOUDS IN THE REGION...AREAS OF DENSE FOG WILL NOT BE WIDESPREAD. COOLER THAN NORMAL TEMPERATURES AND A NOTICEABLE DRIER DEW POINTS ARE ON TAP FOR SATURDAY. TEMPERATURES WILL RANGE FROM THE MID TO UPPER 70S ACROSS THE WEST AND UPPER 70S TO LOWER 80S IN THE EAST. DEW POINTS FOR THE AREA WILL BE IN THE 50S. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/... AS OF 355 PM EDT FRIDAY... RELATIVELY DRY AND COOL HIGH PRESSURE CENTERED OVER THE MID ATLANTIC IS EXPECTED TO DOMINATE THIS PERIOD. NO SIGNS OF ANY CHANCE OF RETURNING MOISTURE UNTIL POSSIBLY MONDAY AFTERNOON IN TEH FAR WEST WITH SFC HIGH DRIFTING OVER WRN NC BY THIS TIME AND 850 FLOW WEAK BUT BEGINNING TO SHOW BETTER WESTERLY COMPONENT. THIS TIME OF YEAR IT DOES NOT TAKE TOO LONG BEFORE JUST ENOUGH LOVE LEVEL MOISTURE SNEAKS BACK IN FOR AT LEAST SOME ISOLATED MTN SHOWERS. KEPT SLIGHT CHC CONFINED TO WESTERN SLOPES BASICALLY. ADDED SOME PATCHY VALLEY FOG FOR SUNDAY MORNING GIVEN HIGH BASICALLY OVERHEAD AND LITTLE IF ANY CLOUDS EXPECTED. HIGH TEMPS AT OR BELOW SEASONAL LEVELS BUT WENT WITH WARMER GUIDANCE GIVEN DRY RIDGE WITH PLENTY OF SUN...AND THEN LOW TEMPS INITIALLY BELOW NORMAL GIVEN CLEAR BUT DRY NIGHTS. WENT WITH COOLER MET GUIDANCE FOR LOWS SAT NIGHT AND SUNDAY NIGHT. BY MONDAY NIGHT LOWS MAY GET BACK TO AT OR ABOVE SEASONAL NORMS WITH LOW LEVEL MSTR ON THE SLOW INCREASE. && .LONG TERM /TUESDAY THROUGH FRIDAY/... AS OF 200 PM EDT FRIDAY... LARGE HIGH PRESSURE DOME OVER CENTRAL U.S. GRADUALLY RETROGRADES WEST DURING THE MID TO LATE PART OF THE WEEK...WITH A GRADUAL SET UP OF WEAK UPPER TROUGH OVER NORTHEAST U.S. AND BETTER NW FLOW AND CHANCES FOR SOME ORGANIZED CONVECTIVE SYSTEMS RIDING OVER TOP OF RIDGE TO MAKE THEIR WAY INTO WESTERN OR NORTHWESTERN PORTIONS OF OUR AREA. VERY HARD TO BE ABLE TO PIN POINT WHICH DAY IS MOST LIKELY FOR THIS TO FIRST HAPPEN. 12Z GFS MOST AGGRESSIVE AT DEVELOPING THE UPPER LEVEL WEAKNESS BY AS EARLY AS LATE TUES INTO WED...WITH 00Z ECMWF AND 12Z CANADIAN IN GOOD AGREEMENT THAT IT MAY BE THURS BEFORE THIS HAPPENS. GFS ALSO TRYING TO SHOW BETTER RETURN OF MSTR UNDER THE RIDGE AS EARLY AS TUES FOR ISOLD TO SCT MOUNTAIN SHWRS AND TSTORMS DEVELOPING EACH DAY...WHEREAS OTHER MODELS APPEAR TO HAVE SUBSIDENCE WITH RIDGE DOMINATING. BASED ON CLIMATOLOGY WITH THIS KIND OF PATTERN...WILL LEAN TOWARD GFS IDEA OF RETURN OF DAILY MAINLY MTN SCATTERED CONVECTION BY TUES...BUT THEN BETTER CHANCES FOR SOMETHING MORE ORGANIZED MOVING INTO WEST BY WED OR WED NIGHT. THE OTHER DIFFERENCE BETWEEN THE GUIDANCE IS HOW QUICKLY THIS BACK SIDE OF THE WEAK TROUGH IS ABLE TO SWING A BACK DOOR COLD FRONT THROUGH THE AREA AND HOW FAR SOUTH IT MAKES IT. OF COURSE MUCH OF THIS MAY DEPEND ON TO WHAT EXTENT ORGANIZED CONVECTION RIDING OVER THE NE EDGE OF THE BIG RIDGE MAY DEVELOP AND HELP PULL THIS BOUNDARY DOWN. GFS FASTEST WITH THE FRONTAL PASSAGE AND BRINGS THIS THROUGH EARLY THURSDAY...WITH ECMWF SLOWER AND MORE LIKE LATE THURSDAY OR THURS NIGHT. THEN BY FRIDAY ECMWF A LITTLE SLOWER TO DRAG BACK END OF FRONT AND LINGERING LOW LEVEL MOISTURE OUT OF THE SOUTHERN APPALACHIANS...THUS SUGGESTING BETTER LINGER THREAT OF SOME ACTIVITY FRIDAY ACROSS OUR SOUTHWEST. FOR NOW...USED A VERY BROAD BRUSH AND ERRED ON THE SIDE OF SLOWER REMOVAL OF MOISTURE THINKING FRONT MAY NOT PUSH AS FAR SOUTH OF US AS MODELS GENERALLY SUGGEST. SO LEFT SOME CHC POPS ACROSS THE SOUTHWEST AND KEPT SLIGHT CHC UP EVERYWHERE ELSE. WITH THE UPSTREAM CONVECTIVE SYSTEMS DICTATING A LOT OF WHAT WILL HAPPEN WITH THE BALANCE BETWEEN THE STRONG UPPER RIDGE TO OUR WEST AND WEAK TROUGH OVER NORTHEAST U.S....JUST TOO MUCH UNCERTAINTY THAT FAR OUT TO SAY FRO SURE WHEN...IF AT ALL...IT MAY DRY BACK OUT. TEMPERATURE WISE...SLOW ARMING TREND EARLY PART OF PERIOD AS RIDGE DOMINATES...THEN SLIGHT COOLING TREND WITH BETTER CHANCES FOR CONVECTIVE AND ASSOC CLOUD COVER/PRECIP...AND POSSIBLE MORE SIGNIFICANT DRYING OUT AND COOLER MINS BY THURS NIGHT OR FRI NIGHT IF BACK DOOR FRONT CAN PUSH THROUGH. HIGHS GENERALLY CLOSE TO NORMAL...BUT LOWS PROBABLY TENDING ABOVE NORMAL WITH MSTR RETURN BY MID WEEK. WENT CLOSE TO ECMWF MOS GUDIANCE. && .AVIATION /20Z FRIDAY THROUGH WEDNESDAY/... AS OF 122 PM EDT FRIDAY... A COLD FRONT EXTENDS FROM CENTRAL WEST VIRGINIA TO NORTHERN VIRGINIA EARLY THIS AFTERNOON. THIS FRONT WILL MOVE SOUTHEAST ACROSS THE MOUNTAINS EARLY THIS AFTERNOON...AND BUCKLE ACROSS THE PIEDMONT TRACKING SOUTHWARD INTO THIS EVENING. SCATTERED SHOWERS AND THUNDERSTORMS MOVED ACROSS THE WEST (LWB/BLF/BCB/ROA) THIS MORNING. THESE SHOWERS AND LINGERING CLOUD COVER HAS KEPT INSTABILITIES DOWN. SCATTERED SHOWERS MAY MOVE OVER THESE AIRPORTS UNTIL THE FRONTAL PASSAGE...BUT THUNDER CHANCES ARE VERY LOW. THEREFORE HAVE LEFT OUT OF THE 18Z TAFS. FOR DAN AND LYH...MOSTLY SUNNY SKIES THIS MORNING WILL GIVE THEM A BETTER CHANCE TO SEE A THUNDERSTORMS THIS AFTERNOON. ISOLATED THUNDERSTORMS AT 17Z WERE IN A LINE FROM KFVX TO KHKY. THUNDERSTORM MAY DEVELOP EAST OF RNK PIEDMONT AIRPORTS THIS AFTERNOON. WILL KEEP TSRA IN THROUGH 00Z/8P THIS EVENING AS A PRECAUTION. FOLLOWING THE FRONTAL PASSAGE THIS EVENING...MOIST LOW LEVELS AND AND EASTERLY FLOW SHOULD KEEP LOW CLOUDS IN THROUGH THE NIGHT. SOME PLACES ACROSS THE WEST MAY ALSO HAVE SPOTTY DRIZZLE OVERNIGHT. DRIER AIR PUNCHES IN SATURDAY WITH SKIES BECOME CLEAR BY LATE MORNING. HIGH PRESSURE WILL CONTROL THE WEATHER PATTERN FOR THE WEEKEND. OTHER THAN SOME OVERNIGHT RIVER VALLEY FOG...VFR CONDITIONS ARE EXPECTED SATURDAY INTO MONDAY. EXPECT A RETURN OF SPOTTY SHOWERS AND THUNDERSTORMS IN THE MOUNTAINS FOR TUESDAY. && .EQUIPMENT...
