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 9, 2:38 PM EST, 2 hours 27 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Jackson KY 338 PM EDT Sat Jun 9 2018 .SHORT TERM...(This evening through Sunday night) Issued at 337 PM EDT SAT JUN 9 2018 Scattered showers and thunderstorms have developed across the area, and will persist for a few more hours before diminishing towards sunset. Aloft a west coast trough, mid continent ridge, and northeast U.S. trough remain in place. A short wave trough extends from near Lake MI to Arkansas, with a second short wave trough over MN and IA. At the surface a wavy quasi-stationary front extends from northern WV northwest to IA, with a wave along the front in northern IN. Numerous outflow boundaries will keep unorganized convection going in our area until the atmosphere begins to stabilize with loss of daytime heating. More organized convection with the short wave trough over the mid MS valley will gradually decrease tonight while pushing south or southeast. After local showers/thunderstorms wane this evening, it is possible some showers and thunderstorms left over from the more organized convection now in the mid MS valley could make it into our area late tonight or early Sunday, but odds are very low and will carry just a slight chance of rain late tonight. Convection on Sunday looks likely, and a remnant boundary from the organized convection over the mid MS valley may help to focus convection tomorrow, though that is not certain. It appears that the previously mentioned surface front will remain too far north to have a significant affect on us, and we will still be waiting on the upstream trough that is currently over MN and IA for additional upper level support. One thing that does appear certain is that precipitable water will continue to increase, with PW in excess of 1.5 inches. Locally heavy rain will become more likely with the marginal risk for excessive rain covering most of the area for Sunday. .LONG TERM...(Monday through Saturday) Issued at 337 PM EDT SAT JUN 9 2018 The exact evolution of the upper air pattern becomes less certain in the latter part of the forecast period. However, at the start of the period a short wave trough slowly moving southeast in general northwest flow should will bring likely showers and some thunderstorms on Monday, with high chance to likely probabilities of showers and thunderstorms continuing into Tuesday. A wavy quasi-stationary front which has been to our north this weekend, looks to make a push south as well, and this will help focus convection at the start of the period. It is possible that we'll get a break in the wet pattern in the middle of the week with the passage of the short wave trough and the front possibly slipping to our south. However there remains considerable uncertainty, and there will be daily shower and thunderstorm chances through the coming week. Locally heavy rains will be most likely at the beginning of the week with PW remaining between 1.5 and 2 inches. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) ISSUED AT 141 PM EDT SAT JUN 9 2018 Isolated to scattered thunderstorms were developing early this afternoon. Storms will remain unorganized and there is low confidence in exactly where a thunderstorm will occur this afternoon into this evening. For the 18Z TAFs have carried VCTS for the remainder of the day. A stray shower or storm may also occur overnight, but confidence is too low to carry in the TAFS. Outside of showers and storms VFR conditions and light winds will prevail through the TAF period. At the present time fog is not forecast at any TAF sites overnight, but if a heavy shower or thunderstorm affects a TAF site or surrounding area fog may need to be added in the next TAF forecast. For Sunday, VFR conditions will prevail into early afternoon, but showers and thunderstorms will likely be more numerous by late Sunday afternoon and into the evening. && .JKL WATCHES/WARNINGS/ADVISORIES...
