Area Forecast Discussion National Weather Service Wilmington OH 244 PM EDT Sun Jun 29 2025 .SYNOPSIS... Warm and humid conditions will continue today and Monday, with chances for showers and thunderstorms continuing. A cold front will move through the area early Tuesday, with drier conditions expected through the middle of the week. Warmer temperatures are then expected again going into next weekend, with the potential for a return of rain and storm chances. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... The stubborn stratus layer that has blanketed much of the region S of I-70 has scattered out a bit early this afternoon, allowing for some peeks of sunshine. The presence of this stratus has inhibited/slowed more robust sfc heating thus far, which could cause a slight delay in CI, and perhaps a bit less instby to be realized later this afternoon. This would tend to suggest convection that may not be /quite/ as intense as the past several days. This being said, the development of more SCT SHRA/TSRA is about to get underway near the OH Rvr to S of I-70, with the expectation for an increase in coverage into early evening. This activity is likely going to be focused near/S of I-70 where the best instby will reside through the daytime. Again, the overall weather pattern today will remain very similar to the past several days. The local area remains on the northern periphery of ridging over the southeastern states, with weak westerly flow aloft, and weak theta-e advection through the BL. The atmosphere is uncapped, with around 2000 J/kg of SBCAPE, and lapse rates through the mid-levels that are not impressive, but sufficient for some deep convection once again. The main threats for today will once again be isolated damaging winds and very heavy rainfall, with the latter being a bigger concern for areas that have already received heavy rain over the course of the past several days. As has been the case, these threats should remain isolated, but could be quite impactful on a very localized scale. For the damaging wind threat, favorable DCAPE values with steep low-level lapse rates will support a threat of isolated gusty winds from downbursts. For the heavy rain threat, PWs of ~2 inches will combine with weak steering flow to allow for heavy rain -- with some storms backbuilding or not moving much for a prolonged period of time. Torrential rain rates of over 1" in 15 minutes, with isolated daily totals near 2" are possible in the strongest storms. Overall, storm organization should be rather poor, with only about 15 knots of deep-layer bulk shear. Heading into tonight, while we will likely see a downtick in convective coverage in the several hours immediately past sunset, rain/storm chances will increase once again during the predawn hours, particularly for EC/SE IN through the Tri-State into N KY as a weak disturbance/remnant MCV approaches from the W toward daybreak. This being said, SHRA/TSRA will be possible just about anywhere, including in central OH by daybreak. This enhanced LL convergence with H8 flow increasing, will support the blossoming/maintenance of several clusters of SHRA/TSRA activity by 09z across the local area. Coverage could be fairly widespread locally by the AM commute, with continued high PWs supporting torrential rain rates and an isolated flooding threat as this activity moves from WSW to ENE. It will be a warm/muggy night tonight with temps dipping into the lower 70s. && .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/... The clusters of SHRA/TSRA expected to stretch from EC/SE IN through the Tri-State into N KY early Monday morning will slowly drift to the ENE, with the expectation for a slow weakening into late morning before redevelopment occurs on a more widespread scale by early afternoon with diurnally-enhanced destabilization supporting clusters throughout the local area. The overall setup on Monday is similar to today from a thermodynamic perspective -- the soundings look quite similar, with PWs approaching 2 inches, and uncapped SBCAPE approaching 2000 J/kg. The difference in the convective potential on Monday is two-fold. For one, there will be a more well-defined source of forcing, as a shortwave moves east through Illinois and Indiana and provides a source of large- scale ascent. For two, the deep-layer wind flow will be a bit stronger, with 25-30 knots of 0-6km bulk shear. While not a particularly high value, it will be enough to support some storm organization (as well as greater coverage), and perhaps a little bit of a greater chance for damaging winds. Heavy rain will remain a concern as well, although storm motions should be markedly quicker than with the activity today and the past several days. So, while the threats expected from storms on Monday are generally similar to the past few days, the overall coverage of storms will be greater -- with a little higher probability of storms becoming severe. The spatial expanse of this potential is approximately the same across the local area. ISO SHRA/TSRA is expected to continue in the local area through Monday night as the front approaches from the W toward daybreak. In fact, we may see another increase in coverage of activity during the predawn hours Tuesday from WC OH through EC IN as the front approaches and the environment remains sufficiently saturated and unstable. Highs on Monday will be seasonable -- topping out in the lower to mid 80s amidst humid/stormy conditions. Temps bottom out in the upper 60s and lower 70s by Tuesday morning as the front progresses into the ILN FA. && .LONG TERM /TUESDAY THROUGH SUNDAY/... A cold front will finish pushing east through the Ohio Valley on Tuesday. Since there is some timing uncertainty regarding exact timing of FROPA, there are lingering chances for showers and thunderstorms along and southeast of I-71 into Tuesday afternoon. These locations may remain dry if frontal passage ends up occurring earlier Tuesday morning. Behind the front, high pressure builds in bringing dry, seasonable conditions through at least Thursday. Low end shower and storm chances return to the forecast on Friday when surface high pressure shifts east allowing more heat and moisture to return. These low probability rain chances continue into the weekend since some diurnal instability is forecast each afternoon and there is a chance that a weak front could approach from the north. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... The LIFR/IFR stratus continues to lift/scatter, with conditions trending VFR area-wide near/shortly after the beginning of the TAF period. SCT/BKN VFR Cu, with some cirrus as well, will prevail through 00z area-wide. Once again, SCT SHRA/TSRA is expected through early evening, as indicated by a PROB30 group at each TAF site. Included a TEMPO at srn sites of KCVG/KLUK/KILN where coverage is expected to be most widespread late afternoon. Brief changes in VSBYs, wind speed and direction can be expected with this activity. After that, generally VFR conditions are expected going into the overnight, though some MVFR fog may develop, particularly at locales where heavy rain occurs and at river valley KLUK. Expect that there will be several clusters of SHRA/TSRA that approach KCVG/KLUK toward daybreak and beyond before activity slowly weakens with eastward extend through the morning hours. This being said, do think there will be ISO/SCT coverage of SHRA/TSRA about the local area prior to 18z with the increased forcing/lift overspreading from the W.
