The episode as NWS JKL wrote it up.
A strong MCS developed NW of Kentucky and dove southward during the day on June 25. By the time it reached Kentucky in the late afternoon and evening, it lost considerable strength and was falling apart. However, the far eastern fringes remained decently strong, resulting in a few downed trees in Montgomery and Powell Counties.
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 25, 6:13 PM EST, 42 minutes earlier. Its key messages:
AREA FORECAST DISCUSSION National Weather Service Jackson KY 713 PM EDT Tue Jun 25 2024 .KEY MESSAGES... - Heat and humidity returns for today and Wednesday. - Next best chance of rain will be Wednesday into Wednesday evening. - Hotter weather is expected to make a comeback by Friday and especially Saturday, with afternoon highs in the low to mid 90s and heat index values peaking around or in excess of 100 degrees. && .UPDATE... Issued at 710 PM EDT TUE JUN 25 2024 Did a quick refresh on the grids to reflect current radar trends including increasing PoP across the western tier of counties along the the LMK border. Also, touched up text and radio products to reflect the changes. The grids have been saved and sent. && .SHORT TERM...(This evening through Wednesday night) Issued at 358 PM EDT TUE JUN 25 2024 Current surface analysis is rather active but synoptically surface high pressure is situated over the region. Mesoscale wise, an MCS, from last night's activity in the Upper Great Lakes, is continuing to dive south-southeast toward the CWA. Dry air over the region is causing the MCS to weaken as it approaches the CWA but a shower or two my clip areas along and north of I-64. Those showers and storms will linger over the next couple of hours before a brief lull in activity is expected for a few hours this evening. Then CAMs try to bring another round of showers and storms to the area as the western half of the current MCS tries to dive southeast into the region after 03Z and lingering through the early morning hours of Wednesday. Wednesday brings about another round of showers and storms. A couple small shortwave perturbations are revolving around a parent trough that will bring a surface low across southern Canada and a cold front through the CWA during the day Wednesday. The SPC has placed areas along and north of the Mountain Parkway in a Slight Risk of severe weather. The rest of the area is under a Marginal Risk of severe weather for cold frontal passage Wednesday afternoon. The timing of the boundary will allow for the best instability building. This is shown in forecast soundings as there's decent forecast severe weather indices in place across the area. Steep low and mid level lapse rates are in place, instability ranging from 2,000 to 2,500 J/kg of CAPE in the afternoon is favorable, PW's around 1.80" (which if materialized could bring some heavy rainfall) even from yesterday's soundings, effective bulk shear has increased slightly across the region which could help promote some longer-lived stronger storms Wednesday afternoon. The biggest threat of the day appears to be damaging wind, but large hail and possibly an isolated tornado cannot be ruled out. However, the potential for increased cloud cover Wednesday morning could limit the ability to build in the best instability which alone could limit the coverage of the thunderstorms. Thunderstorms will taper off from northwest to southeast through the overnight Wednesday but an H850 shortwave is forecast to develop with a surface feature riding along the departing cold front. This secondary surface feature will keep lingering shower and thunderstorm chances across the far eastern third of the CWA through the end of the period. Overall, the entire period will be highlighted by multiple rounds of showers and thunderstorms with high temperatures remaining in the mid-80s to low-90s and overnight lows in the upper-60s to mid-70s. .LONG TERM...(Thursday through Tuesday) Issued at 451 PM EDT TUE JUN 25 2024 The models are in good overall agreement with the long wave pattern through early next week. A more stagnant pattern will be in place across the southern half of the CONUS, as a ridge gradually strengthens with time, mainly centering over the lower Mississippi Valley. Meanwhile, the pattern will be more progressive across the northern half of the CONUS, as short wave energy riding from west to east within the westerlies allow for some bouts of unsettled weather. Eastern Kentucky will be on the southern extent of this activity, with periods of building heat as well as some better chances of convection this weekend. PoPs will linger Thursday behind a slowly departing cold front, mainly across our southeast. Temperatures will start out cooler, with highs in mid 80s and lows Thursday night in the upper 50s and lower 60s in the valleys. Hot weather returns for Friday, as 500 mb heights rise. Enough moisture may also come back to allow for the threat of isolated convection (20%) across our south. Highs will be in the low 90s, with a few mid 90s possible. Saturday will be the overall hottest day, as highs will be similar to Friday, while dew points climb to the low to mid 70s, yielding potential heat indices of around 100 degrees at most locations. Given the increased resultant instability in place, there will also be a better chance of convection (50-60%) Saturday afternoon. A passing cold front Sunday will bring our best overall rain chances, peaking at 50-70%. A brief cool down follows into Monday, with highs retreating to the 80s; however, a resurgence of higher 500 mb heights will bring lower 90s back to the area on Tuesday for highs, with lower chance PoPs (20-40%) making a comeback as well. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) ISSUED AT 712 PM EDT TUE JUN 25 2024 VFR conditions are prevailing across the area and will persist through much of the TAF period. A slow moving MCS is continuing to move toward the area. As a result, opted to add a TEMPO to KSYM and KSME for the potential change in conditions as the decay system moves into the region. Once the MCS dissipates, a brief lull in activity is expected before a cold front brings renewed chances of showers and thunderstorms to all TAF sites after 18Z/Wednesday through the remainder of the period. Lastly, light and variable winds are largely expected except where convection exists. && .JKL WATCHES/WARNINGS/ADVISORIES...
