The episode as NWS RNK wrote it up.
The next event of hydrologic significance in July took place as a strong (for late July) cold front approached the southern Appalachians on the 27th. Rapid moisture return ahead of the front set the stage for widespread showers and thunderstorms across the mountains and eventually spreading into the piedmont. Pre-frontal rainfall broke out early on the 27th as storms took the preferred July 2013 track through the northwest NC mountain counties into southwest Virginia. Repeated bouts of convection and heavy rainfall affected much of this area during the day of the 27th bringing impressive 48-hour gage reports from this area ending at 12Z on the 28th. The top five included Sandy Flats IFLOWS (SDRN7) 7.53 , Wilbar RG DCP (WLBN7) 6.07 , Triplett RG DCP (TPTN7) 5.22 , Parkway School IFLOWS (EKCN7) 4.25 , and Jefferson 2E COOP (JFFN7) 3.48 . In Watauga, Wilkes, and Ashe counties there were several reports of flooded roadways and stranded motorists being rescued.

NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jul 27, 6:44 AM EST, 1 hour 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 744 AM EDT SAT JUL 27 2013 .SYNOPSIS... A LOW PRESSURE SYSTEM MOVES INTO THE NORTHEAST UNITED STATED TODAY WITH A COLD FRONT THAT WILL APPROACH THE AREA LATE TONIGHT. THE FRONT WILL CROSS THROUGH THE MID ATLANTIC REGION ON SUNDAY. LARGE HIGH PRESSURE WILL COVER MUCH OF THE EASTERN UNITED STATES ON MONDAY. && .NEAR TERM /THROUGH TONIGHT/... AS OF 415 AM EDT SATURDAY... WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS CONTINUED EARLY THIS MORNING FROM THE NEW RIVER VALLEY INTO NORTHWEST NORTH CAROLINA. EXPECT PRECIPITATION...MAINLY IN THE WESTERN COUNTY WARNING AREA TO CONTINUE THIS MORNING...THEN THE SHORT WAVE SEEN ON THE WATER VAPOR LOOP COMING THROUGH THE TENNESSEE VALLEY THAT IS ASSOCIATED WITH PRE-FRONTAL SHOWERS AND THUNDERSTORMS WILL REACH THE FORECAST AREA LATE THIS AFTERNOON. THIS WAVE WILL TAKE MOST OF THE NIGHT TO CROSS THE FORECAST AREA. HAVE INCREASED PROBABILITY OF PRECIPITATION IN THE SOUTHWEST THIS MORNING AND KEPT THE PROBABILITY HIGH TONIGHT. THE CLOUDS AND PRECIPITATION WILL LIMIT HEATING TODAY SO MAXIMUM TEMPERATURES ARE STILL FORECAST TO BE BELOW NORMAL. LACK OF HEATING WILL RESULT IN LIMITED INSTABILITY...BUT SLIGHTLY COOLER TEMPERATURES AT 500 MB WILL MEAN LARGER LAPSE RATES WITH WEAK TO MODERATE SHEAR. UPPER JET WILL ALSO BE IN A FAVORABLE POSITION FOR SYNOPTIC SCALE LIFT TONIGHT. WITH SURFACE DEW POINTS BACK INTO THE 60S AND PRECIPITABLE WATER VALUES APPROACHING 1.5 INCHES...HEAVY RAIN IS A THREAT WITH ANY OF THE STRONGER THUNDERSTORMS. THE MILD DEW POINTS WILL KEEP MINIMUM TEMPERATURES IN THE 60Z FOR MOST LOCATIONS OVERNIGHT. USED BIAS CORRECTED MAV GUIDANCE FOR MAXIMUM TEMPERATURES TODAY AND LOWS TONIGHT. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... AS OF 400 AM EDT SATURDAY... THE UNSETTLED WEATHER CONTINUES SUNDAY AS THE FOCUS FOR SHOWERS AND THUNDERSTORMS SHIFTS INTO THE PIEDMONT. WITH A SLIGHTLY SLOWER TIMING OF THE COLD FRONT...BEST CHANCE OF CONVECTION SUNDAY SHOULD BE EAST OF I81. DEPENDING ON HEATING AND INSTABILITY...A FEW OF THE THUNDERSTORMS COULD BECOME STRONG ACROSS THE PIEDMONT SUNDAY AFTERNOON. PLAYED HIGHS SUNDAY CLOSE THE COOLER MOS VALUES WITH READINGS FROM THE LOWER 70S IN THE NORTHWEST TO THE LOWER 80S IN THE SOUTHEAST. TAPER OFF POPS FROM WEST TO EAST SUNDAY NIGHT AS DRIER AIR SPREADS INTO THE REGION. LOWS TEMPERATURES SUNDAY NIGHT WILL RANGE FROM THE UPPER 40S IN THE NORTHWEST TO LOWER 60S IN THE EAST. WEAK SFC HIGH PRESSURE BUILDS IN BEHIND THE DEPARTING UPPER TROUGH MONDAY. WENT WITH HIGH TEMPERATURES MONDAY FROM THE LOWER 70S IN THE MOUNTAINS TO AROUND 80 IN THE PIEDMONT. HIGH PRESSURE SLIDES OVERHEAD MONDAY NIGHT WITH LOWS FROM THE THE UPPER 40S IN THE MOUNTAINS THE LOWER 60S IN THE PIEDMONT. && .LONG TERM /TUESDAY THROUGH FRIDAY/... AS OF 400 PM EDT FRIDAY... UPPER FLOW QUICKLY TRANSITIONS TO A ZONAL PATTERN THROUGH THE LONG TERM PERIODS. A SERIES OF EMBEDDED DISTURBANCES WILL TRAVEL WITHIN THE FLOW AND BRING AN OVERALL UNSETTLED WEATHER PATTERN TO THE REGION FOR MUCH OF THE LONG TERM. HOWEVER...IT APPEARS THAT WED STILL OFFERS THE BEST CHANCE FOR WIDESPREAD RAIN AND ANY FLOODING CONCERNS. A STRONG DISTURBANCE WILL TRACK IN THE MEAN WNW FLOW ACROSS THE REGION FROM THE TN VALLEY TOWARD THE CAROLINAS. A SFC LOW PRESSURE AREA WILL FORM ALONG A WARM FRONT TO OUR SOUTH...REMNANTS OF THE SUN COLD FRONT. DEWPOINTS ACROSS THE REGION WILL BE QUITE LOW IN ADVANCE OF THIS SYSTEM AND WITH AN EASTERLY FLOW SETUP AND RAIN SPREADING INTO THE AREA FROM THE SW...WED LOOKS TO BE A POTENTIAL CLASSICAL WEDGE SETUP RAIN/UNSEASONABLY COOL DAY. WILL NEED TO WATCH RAINFALL AMOUNTS AS UPSLOPE FLOW COULD ENHANCE RAINFALL ALONG THE BLUE RIDGE...BUT MOST IF NOT ALL OF THE CWA WILL REMAIN ON THE COLD SIDE OF THIS SYSTEM WHICH SHOULD KEEP QPF IN CHECK. GFS GRIDDED DATA SEEMS TO HAVE THE BEST IDEA ON WHAT COULD POTENTIALLY HAPPEN...WITH MOST ALL OF THE GUIDANCE TRENDING TOWARD CLIMATOLOGY. MAX TEMPS WED COULD BE NEARLY 20 DEGREES BELOW NORMAL...WITH HIGHS IN THE 60S ACROSS MUCH OF THE CWA...BUT HAVE COMPROMISED FOR NOW AND ADVERTISED HIGHS IN THE 70S...EXCEPT NW MOUNTAINS WITH HIGHS IN THE 60S. LIKELY TO CATEGORICAL POPS ACROSS THE SOUTH...WITH CHC POPS FURTHER NORTH AWAY FROM THE DISTURBANCE. FOR THE REMAINDER OF THE EXTENDED...EXPECT A RETURN TO MORE TYPICAL SUMMER CONDITIONS AS THE WED SYSTEM DEPARTS. MAX TEMPS WILL RETURN TO MORE NORMAL READINGS...ESPECIALLY BY THE END OF THE WEEK AS 850MB TEMPS WARM CLOSER TO +20C ACROSS THE PIEDMONT. AREAS LIKE KDAN MAY BE APPROACHING 90 BY THAT TIME. TYPICAL MORE DIURNAL SHRA/TSRA ACTIVITY EXPECTED...WITH SOME FOCUS DEPENDING ON UPPER SHORT WAVE TIMING FROM DAY-TO-DAY. && .AVIATION /12Z SATURDAY THROUGH WEDNESDAY/... AS OF 740 AM EDT SATURDAY... WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS WILL CONTINUE FROM CENTRAL VIRGINIA INTO SOUTHWEST NORTH CAROLINA THIS MORNING...IN ADVANCE OF A WELL DEFINED SHORT WAVE ROTATING AROUND AN UPPER TROF. EXPECT MVFR CEILINGS AND VISIBILITIES WITH ANY OF THE STRONGER SHOWERS AND STORMS. LOW CONFIDENCE...BUT THERE MAY BE A BREAK BETWEEN THE RAIN WITH THIS SHORT WAVE AND THE SHOWERS AND THUNDERSTORMS COMING OUT OF THE OHIO AND TENNESSEE VALLEYS...AHEAD OF A COLD FRONT APPROACHES FROM THE WEST. AS SURFACE AND LOW LEVEL WINDS BECOME SOUTHWEST...HAVE MVFR CEILINGS IN OVERNIGHT. MEDIUM CONFIDENCE THAT CEILINGS WILL STAY ABOVE IFR. THE COLD FRONT THAT EXTENDED FROM MICHIGAN TO SOUTHERN MISSOURI THIS MORNING WILL CROSS THE AREA WITH MORE SHOWERS AND THUNDERSTORMS ON SUNDAY. THERE IS STILL A CHANCE OF LOCALIZED SUB-VFR CONDITIONS EAST OF THE BLUE RIDGE. MONDAY INTO TUESDAY...SURFACE HIGH PRESSURE BUILDS OVERHEAD. THIS WILL YIELD LIGHT WINDS AND LIMITED CLOUD COVER...BUT NIGHTTIME AND EARLY MORNING FOG AND STRATUS WILL BE POSSIBLE THANKS TO PLENTY OF BOUNDARY LAYER MOISTURE IN PLACE AFTER THE RAIN. && .RNK WATCHES/WARNINGS/ADVISORIES...
