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 11, 3:42 PM EDT, 1 hour 40 minutes earlier.
Area forecast discussion, Jun 11, 3:42 PM EDT, 1 hour 40 minutes before
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 342 PM EDT Fri Jun 11 2021 .SYNOPSIS... A weak surface low will track just southeast of the forecast area this evening, as northerly flow aloft follows a departing upper trough. More upper level energy will track south through the Ohio Valley this weekend, and another surface low will cross with a weak cold front from northwest to southeast overnight Saturday. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... Shower and thunderstorm activity will continue to track south- southeast across the region this afternoon and evening, with the bulk of the strongest storms found southeast of the I-71 corridor. With the loss of daytime heating, these storms will rapidly decrease in coverage and intensity. Sky cover will also decrease overnight in the northwest and then build early in the day as shortwave energy tracks south over the region. Overnight lows will bottom out in the mid to upper 60s. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/... The cloud cover from the morning passage of the upper shortwave energy will see more breaks of sun as the overall airmass will be drier. The drop in low level moisture will also permit a more rapid warming as highs reach into the upper 80s with less humid air. Saturday evening will have the surface low in northern Ohio drape a weak cold front through the CWA, with continued chances of scattered showers and thunderstorms. Lows in the mid to upper 60s will occur for yet another overnight period. The showers and thunderstorms may linger through the overnight hours as the front slowly tracks southeastward. Lows will be in the upper 60s. && .LONG TERM /SUNDAY THROUGH FRIDAY/... Weak front will bisect the area at the beginning of the period and continue southeast through the day. This will be the focus for showers and some thunderstorms. Airmass will be somewhat drier in the wake of the front, but bigger, more noticeable change will not occur until a second cold front moves through Monday afternoon into the early evening. So temperatures on Monday will be as warm if not a bit warmer than Sunday. And cannot rule out some showers or thunderstorms, mainly in eastern counties, with the second front. High pressure will then build in through mid week with a deep mid level trough across the eastern US. Pattern will become more progressive later in the week with a short wave ridge passing through the area on Thursday and then a short wave trough approaching from the northwest on Friday. At the surface, the high will move off to the east bringing a return of southerly flow. There could be some showers and thunderstorms ahead of a cold front that approach the northwest counties by Friday afternoon. Temperatures will fall back with readings dropping below normal by Wednesday. But that will be short lived as temperatures return to the mid 80s by Friday. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... Shower activity on the increase this early afternoon and the bulk of the deeper convection lies southeast of the I-71 corridor and away from TAF sites today. One lightning strike noted in Logan County on the other side of the corridor with the parent thunderstorm of this losing cohesion and devolving into just a shower. Peak heating is occurring now and for the next hour or two, with little more than just a slight chance of lingering storms through nightfall in and southeast of the TAF sites and I-71 corridor. VFR conditions will be found with some lower stratus developing before daybreak. Given the closer proximity of storms at CVG/LUK containing lightning, this is the only area where VCTS made an appearance with the exception of the next hour at DAY where the upstream development had me include it out of an abundance of caution. Dry weather is expected on Saturday, at least through the early afternoon. .OUTLOOK...Showers with MVFR to IFR possible through Saturday, along with a chance of an afternoon thunderstorm. && .ILN WATCHES/WARNINGS/ADVISORIES...
