775 FXUS61 KILN 082343 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 743 PM EDT Sat Aug 8 2026 .WHAT HAS CHANGED... No significant changes. && .KEY MESSAGES... 1) Showers and thunderstorms will be possible at times through much of the upcoming week. && .DISCUSSION... KEY MESSAGE 1) The airmass across our area has destabilized nicely this afternoon with MLCapes currently in the 2000-2500 J/KG range and this will allow for isolated showers and thunderstorms to develop early this afternoon. There is a weak low level convergent boundary/trough axis that will shift southeast into our area later this afternoon into this evening and this may serve as a focus for somewhat better development as we head through the rest of the day. While coverage should not be as widespread as what we saw on Friday, it will still be tough to rule out a few strong to severe thunderstorms. Damaging wind will be the main threat, along with the possibility for locally heavy downpours. In west to northwest flow aloft, additional mid level short waves will drop down across the southern Great Lakes and into the upper Ohio Valley over the next several days. There is some uncertainty for Sunday into Sunday night with how well a potential MCS off to our northwest will hold together as it moves down toward our area. For now, will limit pops to chance or less, mainly across northern portions of our area. Beyond that, timing and placement remains problematic, but occasional rounds of showers and storms can be expected Monday through at least Wednesday, but possibly lingering through the end of the week, as we remain in northwest flow aloft. Deeper layer shear will trend upward through mid week, so the threat for severe storms will likely continue through at least Wednesday. Locally heavy rainfall will also remain possible with isolated flooding a continued threat. More widespread flood concerns may also develop if we start to get repeated rounds of heavy rainfall over the same locations. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/... Thunderstorms will continue about the region during the early part of the period before dissipating. Then after 06Z, there will be the potential for some fog development, particularly at KLUK and KILN where a period of IFR visibility is possible. And restrictions will end by 13Z with few to scattered cumulus developing during the day. OUTLOOK...Thunderstorms are possible at times through Thursday. && .ILN WATCHES/WARNINGS/ADVISORIES...
