The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Wilmington, OH wrote its last area forecast discussion before this special weather statement went out at May 23, 4:15 PM EDT, 3 hours 6 minutes earlier.
Area forecast discussion, May 23, 4:15 PM EDT, 3 hours 6 minutes before
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 415 PM EDT Sat May 23 2020 .SYNOPSIS... A weak warm front will lift across the area tonight. Warm and humid conditions will occur through much of the week with a chance of thunderstorms each day, primarily in the afternoon and evening. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Storms have developed from central Indiana into central and eastern Kentucky. Much of this activity is heading east northeast. Instability axis remains oriented northwest to southeast cutting across the Tri-State. As storms continue to progress, expect them to weaken as they move out of the more favorable environment. Thus northern activity will likely decrease first with more robust storms moving across northern Kentucky, southeast Indiana, and southwest Ohio. Conditions still look favorable for a few severe storms with damaging winds and/or hail. Showers and thunderstorms will likely continue into the late evening as they continue across the southern part of the forecast area all the while weakening. Meanwhile tail end of short wave lifting through the Great Lakes overnight could result in some additional showers or thunderstorms developing south into central Ohio later tonight. Lows will only fall into the mid 60s. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... Warm and humid conditions will occur with highs getting a few degrees warmer than today and lows likely being just a bit warmer as well. A weak disturbance is forecast to move from Tennessee into Kentucky during the day. This will result in a chance of showers and thunderstorms again across southern counties during the afternoon. && .LONG TERM /MONDAY THROUGH SATURDAY/... The extended period will start with a continued warm trend that begins in the short term, with light winds and scattered diurnal convection through mid-week. A cold front will bring cooler, drier conditions into the weekend. Mid-level ridging centered over the Appalachians on Monday will slowly shift to the Eastern Seaboard through mid-week. Meanwhile, low pressure will remain anchored over the southern plains, cut-off from the jet in southern Canada. This will place the forecast area in a continued southwest to southerly flow regime aloft. At the surface, a sprawling Bermuda high pressure will provide southerly winds, increased dewpoints, and above normal temperatures. A stalled frontal system over the Mississippi Valley will keep most concentrated shower development to the west; however, scattered convection will still likely develop in an unstable airmass. By late Wednesday into Thursday, a stronger northern stream shortwave will shift eastward into the Great Lakes, flattening the Bermuda ridge and allowing the frontal system to progress toward the southeast. This cold front will provide our highest precipitation chances of the week by Thursday, followed by cooler, drier air pushing into the Ohio Valley Friday into the Weekend as a mid-level trough becomes established over the East Coast. As would be expected, ensembles vary in how quickly Thursday's front pushes south of the area. Most of the EPS members, along with nearly all of the GEFS members, clear the front and establish surface high pressure for the weekend. Decided to lean toward this solution, reducing NBM isolated to scattered PoPs by a category Friday night through Saturday. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... Scattered to broken cumulus will occur through the early part of the TAF period. Expect to have convection after 21Z. The best chance of that occurring is in the Cincinnati area and thus have included TEMPO groups for a few hours there. Convection will move east and weaken after 00Z. Will have a lingering mid deck which will likely clear overnight. Expect some visibility restrictions to develop at KLUK. Would not be surprised if some fog or stratus occurs elsewhere, although that signal is too subtle to include a mention in the TAFs at this time. Cumulus will redevelop late in the period with heating. OUTLOOK... Thunderstorms are possible, mainly in the afternoon and evening each day, through Thursday. && .ILN WATCHES/WARNINGS/ADVISORIES...
