FXUS61 KILN 081004 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 604 AM EDT Wed Jul 8 2026 .WHAT HAS CHANGED... No major changes from previous forecast. && .KEY MESSAGES... 1) Scattered thunderstorms are possible today and tomorrow primarily south of I-70. 2) A larger system arrives near the end of the working week, reintroducing a heavy rain and localized flooding threat. && .DISCUSSION... KEY MESSAGE 1) A loosely organized low lifting northeast from the Gulf through the Appalachians this evening into Thursday. As this system clips our southerly counties, a renewed chance for largely diurnal scattered thunderstorms will be possible Wednesday and Thursday afternoon. Overall severe threat is low, but an increase in low and mid level moisture (PWATs around 1.9 inches along the Ohio River) and training storm motion may result in an isolated flooding threat. KEY MESSAGE 2) Attention then turns toward the end of the working week and into the weekend when the chances for heavy rainfall increase. A slow moving cold front sagging down from Canada will lay out zonally across the southern Ohio Valley. This zonal flow will provide the focus for several shortwave disturbances to ride along and drop southeast through the Great Lakes region later this week. These features look to impact our area Thursday through Saturday, with rounds of showers and thunderstorms once again expected in a very moist airmass. PWATs of 2+ inches, skinny CAPE, the potential for W to E training storms, and multiple rounds of storms will introduce a heavy rain and localized flooding threat. While our entire area will receive accumulating rainfall, the greatest QPF footprint appears currently to be across central Kentucky, with a widespread 1-3 inches currently painted across KY from Thurs- Sat based on ensemble plumes, with the gradient lessening the farther north you go. Of course, locally higher amounts will be possible with stronger storms and those locations is where the greatest flooding threat will be. Many details still remain to be worked out and the axis of highest QPF may shift, but will likely start messaging the heavy rain threat for areas south of I-70. && .AVIATION /09Z WEDNESDAY THROUGH SUNDAY/... Patchy fog burns off after sunrise and diurnal cu build in during the afternoon. Some high level cirrus will overspread from the south. Calm winds this morning will give way to very light northerly flow around 5 knots or so through the afternoon hours. Scattered PM thunderstorms are expected in southern Ohio/ north central Kentucky and almost added in a PROB30 at LUK and CVG from 00z tonight through 4z Thursday, but signal is more robust to the southeast of the TAF sites so held off. However, mentioning the chance here for awareness. Winds subside again after sunset and patchy fog will develop again, mostly in river valleys and rural areas. Outlook...Thunderstorms possible Thursday through Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && $$ DISCUSSION...Aiena AVIATION...Aiena
