NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jul 12, 12:57 PM EST, 5 hours 7 minutes earlier.
Area Forecast Discussion National Weather Service Wilmington OH 157 PM EDT Sat Jul 12 2025 .SYNOPSIS... Showers and thunderstorms are possible through Sunday, particularly in the afternoon and evening before drier conditions returns for the start of the workweek. Warm temperatures drop closer to normal on Sunday and Monday, with warmer and more humid air returning by midweek. Several rounds of showers and storms will be possible midweek and beyond with a return to a more active pattern. && .NEAR TERM /THROUGH TONIGHT/... A lead mid level shortwave lifts northeast from the mid MS Valley into the Great Lakes today getting absorbed into a larger/deeper trough digging southeast into the Great Lakes. The Ohio Valley is in a warm southwesterly flow which supports hot and humid conditions with increasing instability to support storms this afternoon into this evening. Scattered showers and thunderstorms have developed in the unstable airmass where SBCAPE values of 2000-2500 J/KG exist. With initial shortwave pivoting into the Great Lakes - better wind flow will remain north of the area. Deep-layer shear will be weak, with effective shear around 15 kts, so storm organization should be limited. DCAPE values of 1000-1200 J/kg suggest that gusty to damaging winds will be possible due to downburst/outflow with the strongest storms thru early evening. Locally heavy rain and isolated flooding is also possible due to PWat values around 125% of seasonal normal. Regarding coverage - initial scattered activity will push off to the east before another area of storms moves into the west late day into this evening and weaken as they track east due to loss of heating. Can not rule out isolated lingering showers or even a thunderstorm into the overnight hours with surface front moving into the area toward sunrise. Warm and muggy conditions will continue tonight with lows in the in the upper 60s and lower 70s. && .SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/... A southwest flow aloft continues over the area until mid level trof axis pivots thru the Great Lakes Sunday night. Slow moving front slips into the area Sunday and stalls out and washes out Sunday night. Although forcing is weak expect some isolated to scattered showers and thunderstorms to develop, with the best coverage southeast of I-71 where the best instby will develop in the 1000-1500 J/KG range. Highs to top out in the mid and upper 80s. Have mainly a dry forecast Sunday night but confidence is rather low with some members producing pcpn ahead of an embedded shortwave trof axis. Lows are expected in the mid and upper 60s. && .LONG TERM /MONDAY THROUGH FRIDAY/... Weak high pressure pushes southeast into the middle Ohio Valley on Monday and will drift a bit to the east on Tuesday. With the old cold front to our south, most of the precipitation should stay in that direction, with only a slight chance due to spatial differences in the models. This sporadic convection continues Tuesday afternoon as moisture begins to return on the back side of the surface high. Mid-level heights will increase Wednesday in response to an approaching shortwave across the upper Midwest into the upper Great Lakes. Even so, there could be disturbances ejecting ahead of the wave. In the hot and humid boundary layer, expecting an increase in showers and storms both Wednesday and Thursday afternoon. A cold front will arrive into the lower Great Lakes or Ohio Valley Friday, so storm chances will continue this day. As the front sags south, we could keep a chance for storms southeast of I-71 into Saturday. Temperatures will generally be above normal through the extended period with perhaps slightly cooler conditions by week's end if the cold front clears our area. && .AVIATION /17Z SATURDAY THROUGH WEDNESDAY/... Scattered thunderstorms will develop thru the aftn into the early evening in the warm unstable airmass ahead of cold front. A few of the stronger storms could produce gusty or damaging winds early. Shower and thunderstorm activity decreases with the loss of heating but an isold shower or thunderstorm will remain possible thru the overnight hours with the front moving into the area late. VFR conditions drop to MVFR past 06z through daybreak Sunday before lifting/scattering once again by 15z. Some MVFR VSBYs in fog cannot be ruled out tonight. Additional showers and thunderstorms are possible Sunday with the bes coverage over the east. Have limited any mention to prob30 at KCMH/KLCK. Southwest winds at 10-15kts, with gusts up 20kts this afternoon decrease this evening and veer to the west by daybreak Sunday. West winds at less than 10 kts expected Sunday. OUTLOOK...Thunderstorms are possible Wednesday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && SYNOPSIS...AR NEAR TERM...AR SHORT TERM... LONG TERM... AVIATION...AR
