The episode as NWS JKL wrote it up.
Strong to severe thunderstorms blew down trees and utility lines across Laurel and Leslie Counties, while also causing flash flooding across portions of Laurel County on June 30, 2019. Downed utility lines near Wendover in Leslie County resulted in a three car pileup on U.S. Highway 421. The city of London experienced flash flooding for a short period of time late in the evening of June 30th into the early hours of July 1st. Several roads had 6 to 12 inches of water flowing across them and some homes in the area had the same amount of water flowing through their yards.
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 Jackson, KY wrote its last area forecast discussion before the first event at Jun 30, 10:00 AM EST, 2 hours 35 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED National Weather Service Jackson KY 1100 AM EDT Sun Jun 30 2019 .UPDATE... Issued at 1100 AM EDT SUN JUN 30 2019 14z sfc analysis shows relatively weak high pressure in place over eastern Kentucky with lower pressure to the northeast. This has been ineffective in keeping convection from developing - even at this typical diurnal minima - though the main cell that went through Fleming and Rowan County has now dissipated. The clouds are mainly from this cell with other cu popping up in the east and north. Temperatures are shooting higher with the ample sunshine - reaching the upper 70s and low 80s while dewpoints are elevated into the lower 70s for most places. The fog cleared off earlier in the morning and winds are starting to pick up from the west to southwest at 5 to 10 mph. Look for additional showers and thunderstorms to develop later today - mainly favoring the south where PoPs peak in the 50 percent range - per the latest CAMs and NBM. Have updated the forecast to reflect this and tweaked the near term T/Td grids per the latest obs and trends. These updated grids have been sent to the NDFD and web servers, along with the issuance of a fresh set of zones, mainly to remove the morning fog wording. UPDATE Issued at 758 AM EDT SUN JUN 30 2019 A few showers area popping up just north of the area early this morning. Have included some slight chance PoPs generally along and north of the Mountain Parkway through this morning, before blending into higher PoPs as we heat up this afternoon. The rest of the forecast generally remains on track, with fog burning off in the valleys in the next hour. && .SHORT TERM...(Today through Monday) Issued at 405 AM EDT SUN JUN 30 2019 Surface high pressure is centered across the southeast CONUS, with low pressure located across northern New England. A cold front is arced back across the Ohio Valley, before becoming more of a warm front across the Midwest. Aloft, troughing remains situated from eastern Canada down across Mid-Atlantic region. An upper level low is spinning southeast across southwest Quebec, with a stronger upper level ridge still holding fast from New Mexico into the central Plains. The upper level low will make its way across New England through today, with some residual short wave energy moving across eastern Kentucky during the day. This will allow for better convective coverage today, with the CAMs showing the higher PoPs in the southern half of the forecast area. Storm motions will be more progressive today, as winds shift to the northwest through the column; however, still can't rule out some gusty winds, given that MU CAPEs are in the 3000-3500 J/kg range. Highs today will be near or just a touch cooler than yesterday, with most locations seeing upper 80s. Convection will die off into this evening with the loss of heating. The cold front will dissolve as it pushes in from the northeast tonight, likely leaving a moisture and temperature gradient across the area. Lows will range from the low to mid 60s in the northeast, to the mid an upper 60s across the southwest. Heights will recover into Monday, as ridging builds back in from the west, and given the weaker instability and a cap noted in forecast soundings, convection should be held in check on Monday, besides perhaps a stray shower or storm dotting the I-75 corridor, where the better moisture will reside. Highs will be back in the upper 80s to near 90 degrees. .LONG TERM...(Monday night through Saturday) Issued at 405 AM EDT SUN JUN 30 2019 The models are in good agreement with continued upper level ridging over the southeastern CONUS through midweek. By Thursday, however, the ridge will begin to break down and also begin shifting to the east. A shortwave trough is then expected to progress over the Ohio Valley for late week. However, the models begin to diverge in solution by Friday, particularly with the northern stream flow. At the surface, high pressure will be to the southeast of the Commonwealth, but a cold front will advance towards the state by Friday. This pattern will lead to chances for isolated to scattered showers and thunderstorms during the afternoon and evening each day through Thursday. By late week, chances of showers and storms will be on the increase area-wide for eastern Kentucky as the cold front approaches. Warm and humid conditions are expected to persist through the week. High temperatures will be in the upper 80s to lower 90s through Thursday before a slight cool down to the mid to upper 80s for Friday and Saturday. Low temperatures will generally be in the upper 60s to lower 70s through the period as well. Although, with light winds and clearing skies at night, the valleys will likely be cooler than the ridges through at least Wednesday morning. && .AVIATION...(For the 12Z TAFS through 12Z Monday morning) ISSUED AT 758 AM EDT SUN JUN 30 2019 MVFR or worse fog will burn off by 13z. Isolated to scattered showers and thunderstorms are expected to develop through this afternoon across the area. Have included a period of VCSH/VCTS at all TAF sites, with showers first seen in the vicinity of KSYM this morning. Have maintained VFR conditions; however, any direct hit from a thunderstorm will bring temporary IFR or worse conditions to any given location. Convection will likely die off once again towards 00z. Outside of thunderstorms, light west southwest winds will increase to 5 to 8 kts out of the northwest during the day, before becoming light after dusk. && .JKL WATCHES/WARNINGS/ADVISORIES...
