AREA FORECAST DISCUSSION National Weather Service Wilmington OH 300 PM EDT Wed Jul 31 2024 .SYNOPSIS... Seasonably warm and humid conditions will lead to occasional chances for thunderstorms through the end of the week and even into the upcoming weekend. A drier airmass will settle into the Ohio Valley early next week, with seasonable temperatures expected to persist. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... MCS progressing across Indiana early this afternoon has been weakening on the northern side but maintaining itself/strengthening on the southern side. The best instability is currently across portions of southern Indiana and much of Kentucky. Thus expect this activity to continue to feed south southeast into that region over the next few hours. This will likely put our far southwestern counties on the fringe of the stronger activity with the best chance for any severe storms most likely to the southwest of the Cincinnati metro area. On the backside of this MCS, pcpn will taper off and expect a general lull as we head into the overnight hours. However, it does look like another MCS will develop off to our northwest tonight and track southeast toward our area late tonight. This will likely be in a weakening state as it moves into our area so will just bring some higher end chance pops into parts of our west late tonight. Lows tonight will be in the lower 70s. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... The remnants of the overnight MCS will likely continue to dissipate across our area through Thursday morning. This will once again add some uncertainty as to how things will unfold Thursday afternoon into Thursday evening as this could have some mitigating effects on our temperatures and instability as we head through the day. Nonetheless, temperatures should eventually push into the upper 80s to lower 90s. This will combine with dewpoints in the mid 70s to push indices to around 100 degrees or so in the afternoon. Once again there remains some uncertainty with the possibility of another MCS dropping southeast toward the destabilizing airmass across our area later Thursday afternoon into Thursday evening. Given this, will limit pops to just high chance across most of the area for late into the day and Thursday evening. A few strong to severe storms would once again be possible with damaging winds and locally heavy rain being the main threats. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... A surface low and upper level vorticity max will progress through the Ohio Valley on Friday and Friday night. Showers and storms are likely to occur ahead of the system especially on Friday afternoon into Friday evening when diurnal instability should most favorably overlap with forcing. Some storms could pose a severe and flood risk in the high DCAPE and high PWAT environment. Damaging winds and isolated flooding are the main concerns. Forecast highs on Friday have a fair degree of uncertainty due to the possibility of convection. If storms form early, highs could be limited to the lower or middle 80s. If more sunshine occurs deeper into the day, highs could easily push 90. Temperatures remain warm and humid Friday night with southerly flow remaining in place. The surface low and upper level trough remain overhead on Saturday which could support some unsettled conditions with rain showers. Winds shift to the northwest on Saturday which helps keep highs in the lower to middle 80s areawide. The low moves east of the area by Sunday when high pressure moves across the Ohio Valley into at least Monday. Temperatures drop closer to seasonal averages with northerly flow in place to start the week. Dry conditions are expected. Heat and rain chances start to slowly increase toward the midweek as another boundary may move into the region from the north. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... Remnants of the earlier convective complex are pushing across eastern Indiana into western Ohio/northern Kentucky attm. The stronger storms have been focused along the southern edge of this where the instability has been increasing this afternoon. This activity will likely continue to build east southeast into the better instability and generally remain to the southwest of our TAF sites. However, with KCVG/KLUK remaining on the fringe of the instability gradient, will allow for a tempo TSRA for a few hour period there later this afternoon. Elsewhere, will limit pcpn chances to just a VCTS at the remaining TAF sites. On the back side of this activity, expect to see a lull in pcpn later this evening into the overnight hours. Some of the hi res models are suggesting some additional thunderstorm activity dropping southeast toward the region late tonight into Thursday morning. There is some uncertainty with this though so will just bring a vcsh back into the TAF sites toward the end of the period to account for this. OUTLOOK...Thunderstorms are possible Wednesday night through Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
