Special Weather Statement, NWS Wilmington, OH

AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
1011 PM EDT Fri Jun 18 2021

.SYNOPSIS...
Severe weather through part of the night with flooding concerns
also likely into the overnight hours. Additional severe threat
on Saturday with a boundary in the area. Continued thunderstorms
will be possible through the weekend and into early next week
until the frontal passage.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Thunderstorms continue across portions of the area. Damaging
winds and flash flooding will be the main threats. Isolated
tornadoes and hail will be possible as well. Expect additional
thunderstorms to move into the region overnight. Flash flooding
will be a significant concern. Only took away the northern tier
of the flood watch for now given uncertainty with how far north
convection will reach overnight. Flooding is even more of a
concern with timing at night.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
Showers and thunderstorms will be ongoing during the morning
hours with a lull around mid day. Additional thunderstorm
development going into the afternoon and evening hours. Severe
weather with the potential for damaging winds will be possible
in the afternoon and evening hours.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
The extended period begins Sunday with shortwave ridging over
the Ohio Valley into lower Great Lakes ahead of a progressive
deepening trough moving southeast into the northern plains.
Meanwhile, tropical remnant slowly lift northeast through the
southeastern United States. This pattern will lead to plenty of
heat and humidity Sunday through Monday. As far as
precipitation, moderate instability Sunday with minimal forcing
provides a chance of mainly diurnal storms. However, by Monday,
the approaching trough and associated cold front brings better
chances of convection.

There is some signal for development of a southwesterly low-level
jet Sunday night into Monday morning, so PoPs start to increase at
this time. Heading into the afternoon, timing of the front will be
critical in deciphering peak instability... along with associated
severe threat. Based on current guidance, front appears to push
through the region during the afternoon, so best instability
develops south and east of Interstate 71 corridor. In addition, the
ECMWF and the tail end of the NAM bring a secondary wave along the
front late Monday evening into the overnight, with significant
uptick in PoPs across the southeast part of the forecast area at
that time. Will continue to monitor this period for severe and
flooding threat as details become more clear.

Conditions dry out behind the front Tuesday afternoon as high
pressure quickly builds into the Ohio Valley. High temperatures will
likely be head to around 70 degrees with lower humidity values.

The surface high slides east through mid to late week as
temperatures warm again in southerly flow. Mid-level ridging
provides a break in the precipitation during this time, though can't
rule out an isolated afternoon storm by Friday as low level moisture
increases.

&&

.AVIATION /02Z SATURDAY THROUGH WEDNESDAY/...
Thunderstorms moving through several of the TAF sites through
the night. There will gusty winds with these thunderstorms.
There could be a lull in the thunderstorms on Saturday before
additional thunderstorms develop. Some MVFR cigs will be
possible Saturday morning.

.OUTLOOK...Thunderstorms are possible Saturday through Monday
