Area Forecast Discussion National Weather Service Wilmington OH 210 PM EDT Mon Jun 30 2025 .SYNOPSIS... Showers and thunderstorms are expected this afternoon and evening. A cold front will move through on Tuesday, bringing with it additional thunderstorm chances. Mostly dry conditions are expected for Wednesday and Thursday, with warmer temperatures expected by the weekend. && .NEAR TERM /THROUGH TONIGHT/... Ohio Valley remains in a warm sector with a warm and moist air mass in place. Atmosphere has become unstable as well which has helped support scattered to numerous showers and thunderstorms early this afternoon. Given the high moisture content, with precipitable water values near 2 inches, the main threat from storms will be heavy rainfall. In addition to high rainfall rates, any storms that move over the same areas may lead to localized instances of flash flooding. Stronger storms could also produce isolated strong wind gusts, although this risk looks a little less than previous days given slightly less favorable instability (including lower expected DCAPE). Convection will wane in the evening however can't rule out some lingering showers into the night. A disturbance/approaching cold front will bring a better chance or wider coverage of showers across the Tri-State area close to sunrise. && .SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/... Cold front moves across across the area during the daytime Tuesday. Expect showers to be ongoing at the beginning of Tuesday across the Tri-State area, and showers and a few thunderstorms are expected to move eastward through the morning and afternoon hours. Chances of rain will decrease from west to east during the afternoon as drier air starts to move in behind the cold front. Highs will be in the mid 80s. With drier air and high pressure building in Tuesday night, skies will become clear with lows down into the lower to mid 60s. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... The first completely dry day locally in quite some time is expected on Wednesday as sfc high pressure and slightly drier/cooler air builds into the region. This will mark the beginning of a much- needed reprieve from daily widespread shower/storm chances, with an opportunity for areas that have been impacted by recent heavy rain/flooding to dry out a bit. Temps on Wednesday will be slightly below seasonal norms, which will likely be the only day in the long term period where the daily averages may be below normal. A warming trend is expected toward the end of the workweek once again, with the lone exception to this being the potential for a S/W to drift into northeast/central OH into late Thursday, which may bring with it some enhanced cloud cover and slightly "cooler" temps and perhaps some low-end rain/storm chances as well. But the southern progression of this feature is far from certain at this juncture, with trends suggesting that most spots locally will remain dry through this weekend. In general, warmer and more humid conditions will return to the area by this weekend, with dry conditions favored at this juncture. The next opportunity for more widespread rain/storm chances will hold off until Monday/Tuesday of next week. Until then, the ILN FA will feel the impacts of an expanding midlevel ridge across the mid MS Rvr Vly and wrn OH Vly this weekend, offering seasonably warm and humid conditions. The combination of heat and humidity may push heat index values close to 100 degrees by Sunday/Monday, but will wait until there is a bit more agreement in the data before adding to the HWO given the uncertainties in the timing of the arrival of the next front. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... Scattered to numerous showers and thunderstorms have developed early this afternoon in a warm, moist and unstable air mass. Expect a decent coverage of storms to persist through the rest of the afternoon, occasionally impacting terminal sites with brief MVFR/IFR conditions. Coverage should be less this evening, although there is still a chance of showers, with the potential for some MVFR stratus to form late tonight. Guidance is showing some continuity in showers affecting all terminals Tuesday morning as a cold front moves into the area. The cold frontal passage will lead to a wind shift by Tuesday afternoon.
