The episode as NWS RLX wrote it up.
Isolated to scattered thunderstorms developed across northern West Virginia on the afternoon of the 18th in association with a disturbance crossing through the Ohio Valley. Hot and humid conditions ahead of the system aided in storms reaching severe levels, resulting in several trees being blown down in multiple towns within Tyler County.
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 Charleston, WV wrote its last area forecast discussion before the first event at Aug 18, 1:28 PM EST, 12 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Charleston WV 228 PM EDT Sun Aug 18 2019 .SYNOPSIS... Disturbance brushes across north tonight. Hot weather continues for the first half of the week. Cold front crosses by late in the week. && .NEAR TERM /THROUGH MONDAY/... As of 135 PM Sunday... Upper level shortwave trough passing by to our north, with the southern extent of precipitation just brushing across the northern forecast area. Also expect isolated to scattered thunderstorms to develop across the mountains this afternoon. Another upper level shortwave trough crosses the north tonight. This is associated with the showers and storms stretching from Michigan southwest into the lower Ohio Valley this afternoon. Most high res models are showing the remnants of this making into the far NW forecast area overnight so added isolated to scattered showers. Expecting another hot and humid day on Monday, with popup showers and storms for the afternoon and evening. The highest heat index values, in the upper 90s, are expected across the southwestern forecast area. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 211 PM Sunday... The combination of an increase in moisture depth and lowering of height fields on Tuesday should allow for a good scattering of diurnally driven convection. Given the high temps and higher moisture values, an isolated strong to severe storm is possible nearly anywhere in the area. Max temps on Tuesday should be similar to Monday's values. Wednesday will be another very warm and humid day, although thicker cloud cover and continued diurnally driven convection should result in a very minor reduction of max temps values. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 218 PM Sunday... A cold front is prog to move through the area sometime on Thursday, with the GFS being a little faster with FROPA than the ECMWF and CMC. A band of showers and storms is likely to develop along the front, some possibly strong to severe (depending on the timing of the front). If the front pushes far enough south of the area, a very pleasant late week airmass should be in place. Even if the front stalls along the southern CWA, the high moisture values should be replaced with lower dewpoints and max temps should be much lower than what has been occurring this weekend. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 135 PM Sunday... Isolated to scattered showers and storm are expected across the NW and eastern forecast area today, but these are not anticipated to impact any TAF sites. PKB, EKN and BKW have the best chance of a passing shower or storm. Stuck close to what happened last night with regards to dense valley fog tonight. One difference is additional clouds are expected across the northwest, so did not go as low with visibility at PKB. VFR expected after any fog dissipates Monday. Once again, isolated to scattered showers are possible. Did not mention these in TAF yet since the bulk of the activity should be after 18Z. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY... FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: A thunderstorm may impact PKB, EKN or BKW late this afternoon. Timing and density of fog may vary overnight tonight.
