Scattered thunderstorms developed during the late afternoon and evening hours ahead of a cold front approaching the Ohio Valley Region.
The local office's own words before the first event, 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 the first event at Jun 12, 8:10 PM EST, 1 hour 27 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 910 PM EDT Sat Jun 12 2021 .SYNOPSIS... A weak cold front will pass across the region late tonight into Sunday. A second cold front will move through Monday afternoon and evening. Cooler and drier air will then work in for mid week. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... An area of showers and thunderstorms across central Indiana is pushing slowly southeast toward our area. The airmass across our eastern Indiana counties is likely worked over at least somewhat from the convection that occurred there earlier this evening. So, do expect to see a weakening trend with this activity as it moves into our area later this evening. However, will have to keep an eye on it because if it does hold together, it could move over some of the same areas that received some heavy rain earlier. Otherwise, the weak cold front will move southeast into our area overnight. Some of the higher res CAMs are showing some isolated activity lingering with the front overnight so will maintain some lower end pops across much of the area tonight. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... Weak front bisecting the area will continue slowly southeast through the day. Atmosphere will be unstable and expect showers and thunderstorms to develop and increase in coverage during the late morning and early afternoon. This activity will push out of the area before the day is through. Given forecast instability, cannot rule out a few strong to severe storms. With the front moving through along with clouds and precipitation, expect highs to be a little lower with readings in the mid 80s. In the wake of the front, some ridging will work in which will allow skies to clear. Lows will fall back into the upper 50s to lower 60s. && .LONG TERM /MONDAY THROUGH SATURDAY/... Upper level troughing will begin settling into the Ohio Valley from the northeast on Monday as a secondary cold front and weak surface low sweep in from the north Monday afternoon. Showers and thunderstorms are possible ahead of the front due to low level convergence along the front, afternoon destabilization, and DCVA associated with an upper level shortwave arriving with the surface front. Winds shift from the west to the northwest by Monday evening behind the front bringing cooler and drier air to the region. Forecast highs are in the middle 80s and forecast lows Monday night are in the upper 50s. Upper level troughing amplifies over the Ohio Valley Tuesday through Wednesday. Simultaneously, surface high pressure builds in from the northwest. Fair weather will result with highs near 80 and lows in the 50s under light northerly flow. Temperatures start moderating on Thursday when surface high pressure nudges east and upper level heights begin to rise. Developing southerly flow raises highs into the lower 80s. The pleasant surface high fully shifts east out of the area on Friday and the next cold front may start approaching from the northwest. This results in chances for rain by the end of the work week. && .AVIATION /01Z SUNDAY THROUGH THURSDAY/... Isolated thunderstorms are continuing across parts of eastern Indiana early this evening. These have been drifting slowly south so will allow for a VCSH at KCVG/KLUK for the next hour or two as they could get close to them before dissipating. Otherwise, a weak cold front will move southeast across the area late tonight into Sunday morning. This could lead to some scattered showers and isolated thunderstorms later tonight and will generally cover this threat with a period of VCSH. Some areas of fog will also be possible ahead of the front later tonight but this will be somewhat dependent on the amount of higher clouds that may move in from the west. For now, will mainly limit the fog development to the river valleys in the south with some VLIFR conditions possible at KLUK. Some shower activity may linger through late morning and into early afternoon along and southeast of the I-71 corridor but drier air will otherwise filter in from the northwest through the afternoon. .OUTLOOK...No significant weather expected. && .ILN WATCHES/WARNINGS/ADVISORIES...
