Area Forecast Discussion National Weather Service Wilmington OH 142 PM EDT Fri Aug 7 2026 .WHAT HAS CHANGED... No significant changes. && .KEY MESSAGES... 1) Showers and thunderstorms will be possible at times over the weekend and through the middle of next week. && .DISCUSSION... KEY MESSAGE 1) The airmass across the area has destabilized this afternoon with ML Capes up into the 1500-2000 J/KG range. This, combined with weak mid level energy moving through the Ohio Valley, will lead to fairly widespread showers and thunderstorms this afternoon into this evening. Effective bulk shear has nudged up into the 20-30 knot range and DCAPEs are pushing up close to 1000 J/KG, so suppose a few strong to possibly severe storms could be possible. The main threat would be damaging winds this afternoon into early evening along with locally heavy rainfall. The broad upper level trough over the Great Lakes will begin to deepen somewhat as we head into early to mid next week. With continued embedded rounds of mid level energy/weak short waves moving through the trough, we will continue to see occasional chances for showers and thunderstorms at times through early to mid next week. As the flow begins to gradually increase, there will be an uptick in deeper layer shear through this time period. As a result, it looks like there could be a better severe threat early to mid next week. With a warm and moist airmass in place, PWs will remain relatively high, so locally heavy rainfall could lead to an increased flooding threat through this period, especially in areas that see repeated rounds of storms. Somewhat better northwest flow aloft will develop through the end of the week. This should lead to a drier and cooler trend toward the end of the forecast period. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... An upper level disturbance moving through the Ohio Valley will lead to occasional showers and thunderstorms this afternoon into tonight. Some locally heavy rainfall will be possible with the stronger storms and this could lead to brief periods of LIFR conditions at the TAF sites into this evening. As the disturbance moves off to the east, expect a decreasing trend in pcpn overnight. Some areas of mainly MVFR fog be possible later tonight into early Saturday morning. Otherwise, as we destabilize through the day on Saturday, some isolated showers and thunderstorms will be possible through the afternoon. OUTLOOK...Thunderstorms are possible at times through Wednesday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && DISCUSSION...JGL AVIATION...JGL
