FXUS61 KILN 082344 AFDILN Area Forecast Discussion National Weather Service Wilmington OH 744 PM 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 over the Lower Ohio Valley to track slowly east thru the region thru Thursday. As this system tracks to our south - the northern periphery of showers and thunderstorms will affect the southern portion of ILN/s forecast area. Storms will continue to develop in the moderately unstable airmass across the south this afternoon. A very moist environment will exist with PWAT values at 1.75 inches or above. This moist environment and slow storm motion will lead to a threat for heavy rain and localized flooding. Model solutions show a slight down tick in shower and storm coverage later this evening with an increase in coverage late tonight into early Thursday as the shortwave tracks thru the area. There may be a diurnal uptick in the east Thursday afternoon as the system exits the area. KEY MESSAGE 2) The westerlies will push south late this week with an associated slow moving cold front sagging south from Canada and laying out parallel to the mid level flow across the southern Ohio Valley. This zonal flow will provide the focus for several shortwave disturbances which track thru the region this week. These shortwaves and and associated showers and thunderstorms will impact our area Thursday night through Saturday. A very moist environment will be in place with PWAT values of 2+ inches. Multiple rounds of showers and thunderstorms and the very moist airmass, will offer the threat for heavy rain and localized flooding. The greatest QPF footprint appears to be across ILN/s southern counties, with a widespread 1-3 inches with a gradient lessening the farther north you go. Locally higher amounts will be possible with stronger storms and where training storms develop. Uncertainty on the exact placement and amounts exits but will continue to message the heavy rain threat for areas south of I-70. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... VFR conditions are generally expected through the TAF period. A few light showers are possible for the Cincinnati sites this evening. There will also be a chance of showers and thunderstorms later in the overnight and into Thursday morning. A PROB30 group has been continued for the TAF sites for this, though confidence remains too low for a TEMPO or prevailing group. Also, if some clearing develops overnight into Thursday morning, some patchy MVFR fog could occur. For now, this has not been included in the TAFs. Additional chances for showers and storms will arrive after 00Z tomorrow night. Outlook...Thunderstorms are possible Thursday through Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None.
