FXUS61 KILN 192350 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 750 PM EDT Tue Aug 19 2025 .SYNOPSIS... Showers and thunderstorms are possible late this afternoon into the evening ahead of a cold front. Drier and cooler conditions arrive behind the front for Wednesday. A gradual warming trend occurs Thursday through Saturday before the a cold front arrives next week. && .NEAR TERM /THROUGH WEDNESDAY/... A cold front and upper level shortwave trough will approach and enter the Ohio Valley from the northwest this afternoon and evening. Building instability overlaps with forcing ahead of the approaching front leading to the potential isolated to scattered showers/storms. Activity is not expected to get going until after 3pm since instability is slowly working it's way in from the west as seen on SPC meso analysis. Although there is some severe potential with the convection this afternoon/evening, parameters remain fairly low with only isolated damaging wind gusts being a threat. Forecast highs are in the upper 80s to lower 90s this afternoon. Storm activity drops off tonight after FROPA tonight. Winds shift to the northwest and low cloud cover increases behind the front. Forecast lows are in the upper 60s to lower 70s. && .SHORT TERM /WEDNESDAY NIGHT/... Wednesday will feature cooler, drier, and cloudier conditions than when compared with today (Tuesday). Northerly winds behind a cold front limits highs to the upper 70s north of I-70 to the lower 80s along and south of I-70. A few stray showers are still possible around the Scioto River Valley were deeper moisture may linger. Dew points slowly drop into the 60s by the afternoon under mostly cloudy skies. Northerly winds persist into Wednesday night keeping dry conditions in place. Forecast lows are in the middle 60s for most locations. && .LONG TERM /THURSDAY THROUGH TUESDAY/... An axis of the broad mid level ridge centered over the Four Corners region will nose eastward toward the Ohio Valley through the end of the work week. This will result in mainly dry conditions and a bit of a warming trend heading into the weekend. Highs on Thursday will be in the upper 70s to mid 80s, warming to highs in the mid to upper 80s Friday and Saturday. Mid level energy moving through the Great Lakes will help push a cold front southeast across the region Saturday night into Sunday. This could lead to a few showers or thunderstorms but with somewhat limited moisture, will maintain a mainly dry forecast. A cooler and dry airmass will then settle into the region early next week. Highs on Sunday will be in the mid 70s to lower 80s with highs Monday and Tuesday in the 70s. && .AVIATION /23Z TUESDAY THROUGH SUNDAY/... Clearing of lower cu this evening will remain topped by an as deck 12-15kft. This mid deck should begin to break up as IFR clouds work in on nrly cold advection, generally between 08Z and 15Z, lifting to the MVFR/VFR cutoff of 3kft at DAY and ILN. Remaining TAF sites were optimistically scattered out towards 18Z at CMH/LCK/CVG/LUK, though MVFR clouds were introduced back at CVG/LUK towards the end of the period. An isolated VFR shower may hit CMH through 01Z, remaining north of LCK during this time. Winds behind the cold front will turn nrly and hit a minimum under 5kt with lowest cigs found from 07Z through 13Z. Winds pick back up to 8-12kt tomorrow morning, remaining around 10kt through the end of the forecast. OUTLOOK...No significant weather is expected. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None.
