The episode as NWS RNK wrote it up.
An upper level storm system crossed the region during peak heating. The passage of this system aided in the lift needed for thunderstorm development within an already very moist and unstable atmosphere. The environment spawned a couple of severe thunderstorms which produced damaging winds.
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 Jul 23, 1:05 PM EST, 5 hours 22 minutes earlier.
Area Forecast Discussion National Weather Service Blacksburg VA 205 PM EDT Sun Jul 23 2023 .SYNOPSIS... An upper disturbance passes across this afternoon and evening. Low pressure moves along a front across the eastern Carolinas Monday. High pressure builds in Tuesday and remains across the Carolinas through the end of the week, with temperatures warming to above normal be the dry day of the week under high pressure. Temperatures will warm through the course of the week. && .NEAR TERM /THROUGH MONDAY/... As of 146 PM EDT Sunday... A few strong storms possible this afternoon/evening along with heavy rain... Storms already firing up but for now just producing heavy and lightning, maybe some gusty winds, with DCAPEs above 800 J/kg along/east of the mountains. MLCAPEs of 500-1000 J/kg should increase to 1000-1500 this afternoon, with best instability over the NC foothills/piedmont. Locally damaging winds, maybe hail up to nickel size possible in the stronger storms but isolated. Fortunately pwats are in the 1.0 to 1.3 inch range with 1hr rainfall rates of 1.5 to 2.0"/hr observed. This should limit flooding but any repeat storms could cause localized flooding issues through this evening. Shortwave over KY helping enhance divergence aloft with some weak low level upslope convergence as well. Overall not a great setup for numerous storms, so mainly looking at scattered coverage through the evening and most of this moving east of the mountains by late afternoon. Frontal boundary draped over the southeast NC to Florida panhandle tonight with a low pressure wave moving across it may keep shower or storm chances going into the morning Monday in the piedmont. Further west, skies clear enough that fog may become an issue Monday morning barring any leftover clouds from the exiting wave. Monday should be drier but vicinity of the front and another wave aloft may be sufficient for more shower/storm scattered coverage Monday afternoon but most models favor better coverage north and east of our forecast area. So for now, have 30 pops from the Alleghany Highlands of VA southeast to the central VA piedmont, with isolated coverage as far southwest as the New River Valley into the NC piedmont. With moist airmass, low temps will be slightly milder tonight in the mid to upper 60s east to upper 50s to around 60 west. Monday should be seasonably warm with 80s for most except some 70s in the higher elevations. Forecast confidence is moderate to high on most elements except storm coverage. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 120 PM EDT Sunday... An upper level trough will pivot over the region Monday night. This trough exits the region Tuesday with heights building on Wednesday. Rain chances through the period are very low with low and mid level ridging centered over the region. Temperatures will run warmer than normal with 80s across the mountains and low to mid 90s east. Dew points in the 60s are not outrageous for this time of year, but with light winds, temperatures will feel a few degrees warmer than what they actual are. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 130 PM EDT Sunday... Heights continue to increase and so will the temperatures Thursday and Friday. Temperatures across the mountains will range from the mid and upper 80s to low and mid 90s east of the Blue Ridge. Rain chances remain low but could see a late day storm pop-up only to fade in the evening. Some models are keeping the ridge strong over the region into next weekend. If this is the case, an approaching front may not move south of I-64. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 123 PM EDT Sunday... Have mainly VFR through this evening. Scattered storms will be hit/miss this afternoon/evening but best chance will be along/east of ROA/BCB. For now am just going VCTS and amend as necessary. Any storms fade this evening, though DAN could expect to have convection around right through midnight. Overnight the moisture in the low levels and scattering out of clouds will lead to fog at least across the mountains and possibly foothills, so have MVFR to IFR at times, with the lowest at LWB. Fog/low clouds scatter out around 13-14z with VFR thereafter. More storms possible but mainly northeast of a line from HSP-LYH Monday after 18z. High confidence on ceilings/vsbys and wind through 00z, then average on cigs/vsbys overnight. Low to moderate confidence on storms. EXTENDED AVIATION OUTLOOK... More afternoon and evening thunderstorms with possible MVFR ceiling and visibility Monday. Mainly VFR outside of morning fog Tue-Fri. Warmer with just isolated afternoon/evening convection mainly in the mountains. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None. WV...None. && SYNOPSIS...AMS/WP NEAR TERM...WP SHORT TERM...RCS LONG TERM...RCS AVIATION...AMS/WP
