Training thunderstorms this afternoon led to isolated flash flooding in Floyd County.
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, 2:35 PM EST, 1 hour 35 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Jackson KY 335 PM EDT Tue Jun 30 2020 .SHORT TERM...(This evening through Wednesday night) Issued at 335 PM EDT TUE JUN 30 2020 Available shortly... .LONG TERM...(Thursday through Tuesday) Issued at 335 PM EDT TUE JUN 30 2020 The upper level pattern will feature a ridge setting up across the Plains and this feature will push east by Thursday. This will bring rising heights through the end of the week. This will help to suppress convective development through at least Friday, but can’t completely rule out a very isolated pop up storm along the higher terrain. These rising heights will lead to warmer weather through the weekend, with temperatures rising into the upper 80s to lower 90s for the holiday weekend. Then by Saturday we start to get on the edge of the ring of fire so to speak and therefore showers and thunderstorms will uptick in the higher terrain. The heights will continue to show a relative fall through the end of the week into early next week. This breaking down of the ridge will allow for isolated to scattered showers and thunderstorms to develop amid ample MUCAPE of around 2000 J/kg or higher and PWAT greater than 1 inch. However, given the lack of better upper level winds these storms will remain more unorganized in most cases. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) ISSUED AT 254 PM EDT TUE JUN 30 2020 Scattered showers/thunderstorms were ongoing over the region at the start of the period. A further increase in coverage is expected, with a peak late this afternoon. Localized sub-VFR conditions will result. Much of this activity will die out this evening. However, additional showers/thunderstorms can't be ruled out during the period, with the best chance being over our southwest counties late tonight into early Wednesday. Along with that, MVFR ceilings are forecast to develop over our southwest counties in the vicinity of KSME and KLOZ for a time on Wednesday morning. Further northeast, a reduction in clouds will allow for fog development late tonight, with IFR conditions forecast late tonight and early Wednesday. && .JKL WATCHES/WARNINGS/ADVISORIES... Flash Flood Watch until 8 PM EDT this evening for KYZ050-058>060- 068-069-079-080-083>088-108-111>118. && SHORT TERM...HAL LONG TERM...DJ AVIATION...HAL
