588 FXUS61 KILN 131647 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 1247 PM EDT Sun Sep 13 2026 .WHAT HAS CHANGED... No significant changes. && .KEY MESSAGES... 1) Showers and storms possible this afternoon and evening with a marginal risk of severe weather. 2) Additional chances for precipitation are expected during the middle part of next week, along with warming temperatures. && .DISCUSSION... KEY MESSAGE 1) A cold front will progress through the area this afternoon and evening. Isolated showers and storms are possible ahead of the front. A marginal risk for severe storms exists given fairly robust deep layer shear (50+ knots winds aloft) and low to moderate instability in place (~1000 J/kg MLCAPE). However, storm coverage appears to be on the lower end and shear is mostly straight line without much veering in the wind profile. Damaging wind gusts are the most likely threat in any strong storms. The most likely area for storms to occur is across central Ohio. The shower and storm chances end this evening after FROPA. There will be a noticeable drop in dew points behind the front as winds shift to the northwest tonight. KEY MESSAGE 2) Southerly flow redevelops across the Ohio Valley by Tuesday afternoon/evening after a warm front lifts through the region bringing the return of warm, humid conditions. Rain chances start to increase Tuesday night north of I-70 and spread south through the end of the work week. A stationary front slowly sagging south likely will act as a focus for rainfall. Zonal upper level flow could support weak shortwave troughs periodically increasing chances for rain through the week. Tuesday likely features the most widespread heat before temperatures across the north slowly moderate with the front slowly sinking into the area. Areas south of the Ohio River may not experience FROPA until the weekend. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... A cold front will move through the area this afternoon and evening bringing the chance for isolated showers and thunderstorms along with VFR ceilings. Outside of any showers/storms, VFR conditions are likely for the TAF period. Light westerly winds increase out of the northwest after FROPA this evening. Winds gradually veer to the northeast Monday morning. OUTLOOK...Thunderstorms are possible on Thursday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && $$ DISCUSSION...Campbell AVIATION...Campbell
