NWS Wilmington, OH wrote its last area forecast discussion before the first event at Sep 21, 5:08 AM EST, 8 hours 8 minutes earlier.
Area Forecast Discussion National Weather Service Wilmington OH 608 AM EDT Sun Sep 21 2025 .SYNOPSIS... Rain and storm chances return today and will continue on and off through at least midweek. A stagnant pattern is likely to evolve toward the end of the week as well, with periodic chances for rain lingering into next weekend. Above normal temperatures will continue through early this week before a wetter and cooler pattern develops midweek and beyond. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Mainly dry conditions should prevail in the local area through sunrise with a gradual increase in overall cloud cover toward daybreak and beyond. With light SE sfc flow setting up and a bit more in the way of better LL moisture, temps will be a few degrees warmer early this morning than has been the case recently, with lows bottoming out in the lower to mid 60s. Deeper moisture will advect into the local area this morning into the afternoon, with broad SW flow becoming established with the approach of a midlevel S/W into the daytime. Forcing will increase rather abruptly into the afternoon, with an expectation for scattered SHRA/TSRA to develop and move to the NE from this afternoon through early evening. Some moderate instby (MLCAPE ~1200 J/kg), combined with sufficient deep-layer flow/shear to support some organization, will promote several multicell clusters to develop and become the predominant storm mode by mid afternoon. Isolated gusty winds will be possible in the strongest activity given the relatively supportive LL thermodynamic environment (DCAPE approaching 1000 J/kg) and modest shear contributing to weak linear organization with the storms. Given this setup, a severe storm or two cannot be completely ruled out. The environment and forcing should be fairly uniform across the local area, so this activity will be possible just about anywhere through the heart of the daytime, although it should be most widespread near/E of I-75 by early evening. Loss of diurnally-driven instby (as well as stabilizing effect of earlier storms) toward/past sunset should yield a decrease in coverage of activity toward late evening. This being said, with the primary trof axis still hanging back to the W, some forcing will remain in place amidst an amply-saturated environment overnight into Monday morning, so some ISO SHRA may linger through tonight into Monday morning. Highs today will still be above normal (lower 80s W to around 90 degrees E), but should be several degrees cooler than has been the case in the recent pattern, owing to more widespread cloud cover and SCT afternoon SHRA/TSRA. SW winds of 10-15kts will gust close to 20kts at times this afternoon outside of storms. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/... There will certainly be a decrease in coverage of SHRA tonight owing to a temporary reduction in forcing and large-scale ascent, as well as loss of diurnally-enhanced instby. However, a few SHRA may linger during the overnight, with coverage expected to increase from the W toward daybreak and beyond. Temps again dip into the lower to mid 60s amidst scattered to broken sky cover tonight, with clearer skies favored SE of I-71. Large-scale ascent due to more robust jet dynamics will increase through the day Monday amidst continued moisture advection and PWs trending well above normal. With an uncapped environment, SCT to numerous SHRA/TSRA are expected by mid morning through the remainder of the short term period, with several rounds of activity possible for any one location. Coverage should be maximized during the afternoon and evening, alongside an accompanying low-end severe risk once again. A few strong storms with gusty winds will be possible, with an ISO severe storm possible. However, most locales will simply receive some much-needed rainfall (with potential of an inch or more in some spots) along with some rumbles from time-to-time. But the rainy/stormy day Monday will certainly be a departure from the recent pattern of dry conditions and ample sunshine. Highs Monday top out in the upper 70s in WC OH to mid 80s in the lower Scioto Valley and NE KY. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... QPF maximum expected Monday night in our fa as the base of the shortwave trough ejects through the Ohio Valley. CAPE will gradually diminish overnight, but there still may be some convection around that will help with some localized enhancements in rainfall. Given the extremely dry antecedent soil conditions, hydro concerns remain very limited. Synoptically, an elongated longwave trough covers a large portion of the central and eastern CONUS. Global models remain in agreement that this troughing feature remains intact across the Ohio Valley through the entire work week, but does become modified in shape/orientation over time. The modification and placement of this trough will certainly have an impact on rain chances, but also influence humidity and temperature values. Based on latest guidance, the ILN fa does remain on the eastern periphery of the mean trough axis through at least the middle of the work week. This will keep a southwesterly flow pattern intact and thus usher in a more humid air mass. The trough remains very slow to propagate eastward, so we may not be on the back end of this trough through the entire forecast period (which would provide cooler/drier air and lower chances for rain). Thus, daily rain chances remain possible during the entire extended forecast period given this synoptic pattern. However, this does not necessarily mean that everyone will observe measurable rainfall each day. High temperatures will trend near normal during the beginning of the work week, but may dip a few degrees below normals near the end of the week as the base of the longwave trough will be in closer proximity to us. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... VFR conditions will continue through the morning with a gradual increase in VFR cloud cover into early afternoon. Winds around 5kts or less will increase by mid morning out of the SW to 10-15kts, with gusts to 20kts possible outside of SHRA/TSRA. Southerly winds at 5kts or less are expected once again by/past 00z. The main item of interest for today is going to be SCT SHRA/TSRA by the afternoon, with PROB30s included for each of the sites to account for the potential. Was not confident enough to add a TEMPO in just yet, but certainly it may eventually be warranted for a few of the sites. The main concern with this activity is going to be sudden changes in wind speed/direction as well as VSBY. However, impacts at any one terminal should be relatively be brief in nature. Several rounds of showers/storms are possible at each location through the daytime. Coverage of activity will decrease toward/beyond 00z, although some ISO SHRA will linger at times through daybreak Monday. In fact, there is a signal for an increase in coverage from the SW toward daybreak and beyond, so have added a PROB30 at the end of the KCVG 30-hr TAF as well.
