The episode as NWS JKL wrote it up.
Mini supercell thunderstorms developed across eastern Kentucky this afternoon as an upper level system swung through the Ohio Valley. Several of these storms produced damaging winds, including after they merged into line segments. Downed trees resulted in damage to a few homes and vehicles as well as numerous power outages, but fortunately no injuries were reported.
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 24, 10:26 AM EST, 1 hour 29 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED National Weather Service Jackson KY 1126 AM EDT Mon Jun 24 2019 .UPDATE... Issued at 1123 AM EDT MON JUN 24 2019 A few showers and even a thunderstorm just south of Wayne County are ongoing at this time per radar imagery. An outflow boundary has worked into the western counties where temperatures are generally in the upper 70s with dewpoints near 70 while locations further east are in the lower 80s with dewpoints generally in the lower 70s. Upper elevation locations such as Black Mtn are in the upper 60s to 70s. This leads to low level lapse rates near or just below 7C/km. Instability is generally greatest in the east with MUCAPE analyzed 2000 to 3000 J/kg east of the outflow with MLCAPE a less impressive 500 to 1000 J/kg, highest in the Big Sandy region and Cumberland Plateau area near the TN border. Some mid and high level clouds are limiting heating a bit in some spots though the east in the Big Sandy Region is generally cloud free at this time. The initial cell moving into the southwest part of the area will continue to be monitored as it moves northeast along the instability gradient near the outflow as gust winds will be possible with the cell. Gusty winds should be the primary threat as the cells develop and move east/northeast across the area this afternoon to early evening. Model forecasts generally have MLCAPE reaching the 800 to 1800 J/kg range during the afternoon with effective bulk shear of about 30 to 45 KT. This should be sufficient for organized convection primarily linear, though a discrete cell or two cannot be ruled out. The region remains under a slight risk of severe thunderstorms today. Hourly grids were freshened up based on recent observations and radar, satellite, and model trends. UPDATE Issued at 745 AM EDT MON JUN 24 2019 Did a quick update to mainly fine tune the PoPs and QPF in the near term. Also, added in the latest obs and trends to the T/Td grids while removing the valley fog this morning. These updated forecast grids have been sent to the NDFD and web servers. && .SHORT TERM...(Today through Tuesday) Issued at 405 AM EDT MON JUN 24 2019 ...Threat for Severe Storms this Afternoon and Early Evening... 07z sfc analysis shows a broad area of low pressure over the region centered to the northwest of Kentucky. A washed out warm front is lying through eastern Kentucky with most of our CWA in the warm sector replete with high amounts of moisture. As a result temperatures are quite mild currently in the mid 60s valleys to around 70 on the ridges. Dewpoints, meanwhile, are running in the mid to upper 60s with winds light - generally from the south. Some mid level clouds beneath a layer of higher ones have been enough to keep most of the fog away so far this night despite the addition of more rain last evening. Do expect some river valley fog to take hold around dawn as the clouds thin a bit through the rest of the night. The radar is fairly quiet at this hour with just a few light showers in the far southwest. The models are in excellent agreement aloft through the short term portion of the forecast. They all depict a potent trough swinging through the Upper Midwest and into the Great Lakes today and tonight. This trough brings substantial height falls into Kentucky along with plenty of shortwave energy in deep layer southwest flow. The biggest impact from this mid and upper level support passes by this evening with flatter, but still rather quick, flow to follow allowing a gentle rebound in heights into Tuesday. These heights will gradually build later in the day, Tuesday and beyond in response to upper level ridging strengthening along the Gulf Coast. Given the good model agreement have favored a model blend represented by the NBM in the short term along with considerations from the deterministic CAMs and NAM12 for details/timing. Sensible weather will feature a likely active afternoon and early evening through eastern Kentucky. The upper low will push a cold front through the Ohio Valley today crossing eastern Kentucky at peak heating. This should provide good instability for any storms that develop along and ahead of the boundary. Forecast soundings show some directional, but more speed, shear in place for the updrafts that develop allowing them to become strong to severe. A QLCS is expected to pass through later in the afternoon/early evening with damaging wind gusts the main threat, though a brief tornado cannot be ruled out within the line. Any discrete cells out ahead of the main storm cluster will also have the potential for large hail. SPC has the JKL CWA smack dab in the middle of a Slight Risk area and that looks reasonable so will continue to message and highlight in social media. The storms do clear out to the east in most models around or shortly after sunset, though some stragglers - most likely showers - will be possible in the main line's wake. Drier air will eventually win out by dawn Tuesday with a beautiful and mainly dry day on tap - though temperatures will be seasonably warm in the mid 80s for highs. Used the NBM as the starting point for all the short term grids, making only minor, point-based adjustments to the max and min temperatures. Did also smooth out the coarse details of the PoPs and QPF from the guidance today with consideration to the CAMs and NAM12 for details and timing - maximizing both elements in the northeast parts of the CWA by late afternoon. .LONG TERM...(Tuesday night through Sunday) Issued at 340 AM EDT MON JUN 24 2019 The extended will initially feature a period of hot and dry weather, as a ridge of high pressure settles over the region. A pattern change will be in store for the upcoming weekend, however, as a trough of low pressure aloft moves out of Canada and into northern New England. A weak frontal boundary extending southwestward from the parent low may act as a trigger for shower and storm activity across eastern Kentucky from Friday through Sunday. The models still aren't in the best agreement regarding this scenario, so the latter portion of the extended will be low confidence for now. Daily and nightly temperatures should be fairly routine, with highs in the 80s and lows in the 60s expected across the area. && .AVIATION...(For the 12Z TAFS through 12Z Tuesday morning) ISSUED AT 800 AM EDT MON JUN 24 2019 LLWS will linger for another hour or two in the western/northern parts of the area - included the SME and SYM sites. Later on, another round of showers and thunderstorms is then expected to arrive from west to east this afternoon. Have gone prevailing vis to 4sm as this expected band moves through the forecast area. Drier weather follows later this evening. Winds will be light and variable into mid morning before they increase from the southwest to around 10 knots with gusts up to 20 kts likely in the afternoon. The winds will settle down and switch more westerly following sunset. && .JKL WATCHES/WARNINGS/ADVISORIES... NONE. && UPDATE...JP SHORT TERM...GREIF LONG TERM...AR AVIATION...GREIF
