The episode as NWS RNK wrote it up.
The cold front that was over the region on the 29th, made limited progress eastward on the 30th. This feature continued to serve as the focus for afternoon and evening shower and thunderstorm development. A few of these storms increased to severe levels causing damaging winds which downed trees. The storms were noted to have produced heavy downpours due to high rainfall rates, at times reaching 3 to 4 inches per hour which caused localized flash flooding in Ashe County.

NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Aug 30, 1:32 PM EST, 2 hours 4 minutes earlier.
Area Forecast Discussion National Weather Service Blacksburg VA 232 PM EDT Fri Aug 30 2024 .SYNOPSIS... A stalled front over the area will result in another afternoon of scattered to numerous showers and thunderstorms. In general, expecting unsettled weather to persist through the weekend with humid conditions. Cooler and less humid weather arrives for next week. && .NEAR TERM /THROUGH SATURDAY/... As of 203 PM EDT Friday... Key Messages: 1) A stalled front over the area will result in scattered to numerous showers and thunderstorms through early evening. A few strong/severe and torrential downpour 2) Remaining seasonally hot and humid. Storms already firing up across the mountains and along a wedge front in the NC piedmont. High-res models favor greatest coverage along the front/differential heating boundary and over the more unstable air in the west where sunshine was more abundant. Hard pressed to go higher likely coverage as its been hit/miss slow movers. DCAPES not as high as yesterday with a little more moisture around in the low levels, but higher pwats and loading will make for potential downbursts and small hail. Slow movers will lead to flooding potential but gain too widely scattered to have a flood watch. Temperatures this afternoon are forecast closer to the seasonal norm, down a few degrees from yesterday, but still quite warm. Storms should decrease this evening but cannot rule out isolated showers/near the front/Blue Ridge overnight. Fog/stratus likely overnight thru Sat morning, with muggy lows in the 60s to around 70. Saturday, the wedge front heads back north as we get back in the warm sector area wide. Frontal boundary will reach the upper Ohio Valley to lower Missouri Valley by late afternoon. Upper ridge is starting to get shifted further south, so some height falls and upper divergence should lead to particularly better storm development across the Ohio Valley with storms moving into WV by late morning and/or developing in the mountain by mid afternoon. Higher pops will be along/west/north of I-81. With some increase in shear and higher CAPEs, severe storms will be a better potential Sat afternoon mainly northwest of I-81. Forecast confidence is high on temps but moderate/average on coverage of storms through Saturday. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/... As of 220 PM EDT Friday... Key Messages: 1. Storm chances linger into Monday but should see a shift south by then 2. Main hazards are strong winds and heavy rainfall, that could lead to localized flooding. 3. Near to above normal temperatures. Unsettled weather continues through Sunday as front slowly works southeast into and through the area by Monday morning. Higher pops will be Sunday with the front, though increasing cover could offset severe threat more than Saturday. The upper trough axis stays west of our area until Monday evening. Isolated to widely scattered showers/storms are possible again Monday afternoon, though best chance will be along/south of the VA/NC border, with the front not too far away, draped over eastern VA into central NC, but not expecting much potential for any storms that do form to become severe. Sunday should be slightly cooler if we have more clouds but still humid. Highs in the mid to upper 80s east of the mountains, mid to upper 70s west. Monday will be noticeably cooler with the airmass change, high temperatures in the upper 70s in the west and low 80s in the east. && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 300 PM EDT Friday... Key Messages: - Cooler temperatures are expected, with a warming trend expected toward the end of the week. - Shower and thunderstorm probabilities return toward the latter half of the upcoming week. Quiet weather conditions are expected for mid-week, as a surface high extends from the Mid-Atlantic into the Northeast. Given the placement of the ridge, a northeasterly low-level flow will be seen across the region, which should allow (mainly) dry and cooler weather conditions to be seen across our area. Most of the precipitation for the upcoming week should remain to our south, generally in vicinity of a frontal system extending from the South Carolina Lowcountry to the Central Gulf Coast. As a wave of low pressure moves along the boundary, I can't rule out an isolated or scattered smattering of showers/storms across our forecast area. The greatest coverage should be across our southern/southwestern areas. Given an overall lack of forcing, I don't expect any widespread rain events...well, at least at this stage of the game. Much of the convective activity will be driven by moisture spilling northward into our area and interacting with diurnal trends in instability. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... As of 115 PM EDT Friday... Unsettled weather with highly variable cigs/vsbys during the 24 hour valid TAF. Stalled front over the area will result in scattered to numerous showers and thunderstorms. Greatest coverage will be along/southwest of a LWB-LYH line, but will have at least tempo TSRA in for a few hours this afternoon except LYH. Sub-VFR cigs linger across the DAN til 20z at times, otherwise VFR outside of storms through this evening. Looks like a good threat of IFR or lower at most sites tonight with wedge/front in the area and sufficient low level moisture. Cloud cover higher up may impede this but confidence is moderate enough go lower. Winds will remain light and variable through the afternoon, light with exception of thunderstorm outflow where gusts may approach 25 kts. EXTENDED AVIATION OUTLOOK... Stalled front will linger through the weekend. This favors a mix of flight conditions with low confidence on flight categories due to opportunity for showers/storms and nighttime stratus and fog. A more bona fide push of cooler air from the north is expected Monday, suggesting improved conditions for early next week, although still subject to overnight valley fog. && .RNK WATCHES/WARNINGS/ADVISORIES...
