The episode as NWS JKL wrote it up.
Numerous thunderstorms developed this afternoon in a warm and humid airmass. Several of these propagated over portions of Rockcastle County into southern Jackson County, particularly near the town of Annville. A couple of roads were reported as having at least half of a foot of water flowing over them.
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 Jul 3, 2:53 PM EST, 26 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Jackson KY 353 PM EDT Mon Jul 3 2017 .SHORT TERM...(This evening through Tuesday night) Issued at 353 PM EDT MON JUL 3 2017 Scattered thunderstorms continue to fire in an arc from Middlesboro northwestward to Richmond. These slow moving storms have produced brief torrential rainfall and gusty winds. The strongest storm moved right over LOZ producing 1.23 inches in a little over 20 minutes along with a 45 mph wind gust. These storms will continue to be an issue for the next few hours but will likely not move much further to the east thanks to a drier airmass in place to the north and east of JKL. Another band of storms will move quickly into the Lake Cumberland region over the next hour or two and with CAPE analyzed at over 1000 J/kg in this area, these should hold together to some extent through sunset. The forecast tonight into Tuesday is not being made with the greatest of confidence. While the wave noted on radar and water vapor over the Bootheel of Missouri is progged to move east- northeastward across southern Kentucky tonight and into our forecast area Tuesday morning, it will be moving into a more stable airmass during a not so favorable time of day for convection. Thunderstorm activity associated with the system will likely diminish overnight as it moves into the I-75 corridor with at least scattered showers then expanding northeast through the night into Tuesday morning. Should some breaks develop in the clouds on Tuesday, then isolated to scattered thunderstorms will develop. Should these storms be able to erupt, they will do so in a very humid airmass and will have the potential to produce locally heavy rainfall. The clouds should hold temps down tomorrow into the upper 70s to near 80. This system will exit to our east Tuesday night with diminishing PoPs from west to east. .LONG TERM...(Wednesday through Monday) Issued at 353 PM EDT MON JUL 3 2017 With a front hanging overhead and another shortwave set to move eastward across our region, showers and thunderstorms will remain in our forecast Wednesday through Friday. The airmass will be warm and humid with PWATS near 2" so locally heavy rainfall will remain a threat with any storm. The latest model trends then show a cold front pushing through our region Friday into Friday night with dry high pressure following it into our area for the weekend, lasting into Monday. The blended guidance trended in this direction and was accepted with just a slight chance of a shower or storm on Saturday followed by dry conditions Sunday and Monday. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) ISSUED AT 144 PM EDT MON JUL 3 2017 Isolated to scattered showers with a few heavier thunderstorms continue to fire in juicier airmass west and south of JKL and a thunderstorm may impact SME and LOZ through 23Z or so. GOES-16 visible satellite imagery shows that updrafts are having a harder time getting organized from JKL eastward where dewpoints are lower and airmass is more stable, and this trend should continue. Looking ahead to tonight and tomorrow, models are starting to better resolve the convective system over southeast Missouri and are trending much wetter for us as the system seems poised to track across our forecast area. Will trend TAFs more pessimistic after 08Z from southwest to northeast as this system begins to impact our area with showers, lowering CIGs/VSBYs and the threat for thunderstorms. && .JKL WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...ABE LONG TERM...ABE AVIATION...ABE
