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 Jun 12, 4:03 PM EDT, 2 hours 22 minutes earlier.
Area forecast discussion, Jun 12, 4:03 PM EDT, 2 hours 22 minutes before
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 403 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/... Scattered showers and thunderstorms across southern counties will diminish with the loss of heating. Additional showers and thunderstorms that have developed to the west closer to a weak cold front will be able to sustain longer into the evening. Thus expect them to move into the northwest counties. But they should be on a diminishing trend. It is not clear whether precipitation will completely dissipate as the front makes its way into the area. Thus have maintained low chance PoPs near the forecast boundary position. It will be another warm and muggy night with lows in the upper 60s to around 70. && .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 /20Z SATURDAY THROUGH THURSDAY/... VFR conditions will occur at the terminals through the early part of the period with some cumulus which will likely diminish towards 00Z. Scattered showers and thunderstorms will move in from the northwest after 00Z although on a weakening trend. There is enough of a chance to include VCTS at KDAY and VCSH at KILN and KCMH/KLCK. This precipitation will occur ahead of a weak front that will move across the region after 06Z. There is at least a low potential for some additional showers with the boundary. Fog development, mainly ahead of the boundary in the very moist airmass, is uncertain because it is not clear how much cloud cover will occur. For now, have gone with a persistence forecast at KLUK where reduced visibilities are most likely. Looks like there is a window for lower visibilities at KILN as well. But there is potential for fog to be more extensive than what is currently reflected in the TAFs. VFR will be prevalent late in the period with winds becoming northwest at less than 10 kt in the wake of the front. .OUTLOOK...No significant weather expected. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && SYNOPSIS... NEAR TERM... SHORT TERM... LONG TERM...Campbell AVIATION...
