Area Forecast Discussion
National Weather Service Wilmington OH
351 PM EDT Fri Aug 10 2018

.SYNOPSIS...
A cold front located along the I-70 corridor this afternoon will
move slowly south tonight and weaken as it stalls north of the
Ohio River. Thunderstorm activity will be found over the region
as the weakening surface front interacts with an upper level
trough through at least Saturday. The front will push south on
Sunday as the upper trough develops into a closed circulation
drifting southwest over Ohio.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Thunderstorm activity will be on the increase this evening and
scatter out through the overnight hours. Storms will be
lingering however, so some activity will occur through the
night, most likely north of the Ohio River but not necessarily
limited to this area.

As the surface front washes out as it stalls before hitting the
Ohio River, temperatures tonight will drop to the middle 60s
across the region under generally cloudy skies.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
Lingering showers in the morning will continue their downward
trend but then ramp back up as daytime heating interacts with
the lingering surface front to the south and any shortwave
energy that will remain within the deepening upper level trough.
As the front moves into Kentucky later in the day Saturday, the
axis of the upper trough will be bringing in more shortwave
energy. However, the atmosphere should have been well worked-
over so that any lingering convection Saturday night should be
isolated in nature and not contain much thunder. That being
said, I did not remove thunder from forecast and change to just
showery precip. Will let future model runs solidify this
expectation in the forecast.

Saturday will see highs a little cooler - lower 80s in most
locations. Rainfall may necessitate shaving a few more degrees
from this forecast with future updates.

Drier air will be making a strong push on Saturday night over
the northwestern 1/2 of forecast area. Am slightly concerned
about the proximity of a cutoff upper low and going clear to
partly cloudy, but the flow should put any upper clouds away
from the CWA. Overnight lows will drop to 60-63 degrees by
Sunday morning for most of the CWA as dewpoints drop nicely
below 60 degrees for the first time in a while.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
On Sunday, an upper level ridge will continue to amplify as it
pushes northeast into the upper Mississippi River Valley and into
Ontario. As this occurs, a closed upper level low will develop
downstream over the Great Lakes. It appears that the better low
level forcing will remain east of the region on Sunday. Thus, only a
low chance of showers/thunderstorms are expected with the upper low.
Highs will be mainly in the lower 80s.

For Sunday night, pcpn will be diurnally driven over our area but
will likely persist just to our east. Lows will drop into the lower
60s.

Models have come in better agreement in regards to the location and
eventual movement of the upper level closed low Monday through
Tuesday. On Monday, the center of the upper level closed low will be
over the middle Ohio Valley. Again, low level forcing and upper
support favor the eastern zones, while our western zones should
remain dry. Thus, a chance of showers and thunderstorms will remain
across the east. For Monday night into Tuesday, the low will begin
to slowly nudge east. There could be a lingering low chance of
shower/storms in the east on Tuesday, while the west remains dry.
Highs will range from the lower to mid 80s with lows in the lower to
mid 60s.

As the low opens up and moves further east, short wave ridging will
briefly translate across the region Tuesday night.

A short wave will be lifting out of the central Plains and into the
Ohio Valley Wednesday/Wednesday night followed by a northern stream
short wave dropping into the Great Lakes on Thursday. These features
will bring unsettled conditions. At this time, it appears that the
most active period will be Wednesday night into Thursday with
showers and thunderstorms.

Models are in disarray by the end of next week in regards if energy
will close off over the region. Have kept low PoPs for now.

Highs will remain in the lower to mid 80s with lows in the 60s.

&&

.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
Convection firing along and north of the I-70 corridor will
affect CMH/LCK early on this afternoon, then spread southward.
Did not feel that CVG/LUK would definitely get this activity
tonight, so left thunderstorms out at this moment in time in
favor of amending if future model runs can come together with a
more cohesive solution, or if upstream development would
warrant inclusion later this evening. Cigs/vsbys will be lowered
in any TS activity today and tonight, and lower clouds will
likely make an appearance overnight and early tomorrow given the
expected low level injection of moisture from any storms that
are present and stalled surface cold front. Showers and some
lingering thunderstorms will continue overnight given the
proximity of the upper trough and associated vorticity maxima
within it, combined with the washed-out surface front that will
lay out just north of the Ohio River late tonight and early
Saturday.

More showers and some thunderstorms will occur tomorrow
with an increase in coverage and intensity due to daytime
heating.

OUTLOOK...Thunderstorms will remain possible at times through
Sunday, with the greatest chances during the afternoon and
evening.
