AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
1000 PM EDT Wed Apr 17 2024

.SYNOPSIS...
The area dries out through Thursday afternoon before the next
system moves into the Ohio Valley, bringing renewed chances for
rain and thunderstorms. After this system moves through, there
will be a notable cool down over the weekend, before
temperatures rebound slightly next week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
-- Changed Discussion --
All the precipitation has exited the area currently. Cannot
rule out a brief shower or storm across southeastern portions of
the region, however limited any precipitation mention to a
slight chance. Went close to the blend for temperatures
overnight. Increased cloud cover across northeastern portions of
the forecast area overnight. Cannot rule out some patchy fog
across southwestern portions of the region with winds decreasing
and cloud cover being less.

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/...
The weak ridging slowly moves east out of the region, with
mostly sunny Thursday morning skies being slowly replaced with
high clouds by Thursday late afternoon ahead of the next
shortwave system. The attendant weak surface low moves up from
the Ozarks region, bringing another push of theta-e through the
region late Thursday evening. Right now, high temperatures in
the low 80s along the Ohio River and highs in the mid 70s across
central Ohio.

12 and 18z CAM runs indicate a multicell cluster off to our west
quickly congealing into a (possibly bowing?) line as it moves
through out area. Right now, the higher severe threat appears
to be closer to the Tri- State, where forcing with the shortwave
is a bit stronger. In terms of hazards, primary concerns will be
damaging winds and large hail. With that being said... time of
arrival is still a bit up in the air and there is some question
as to whether the line arrives late enough in the evening that
available instability will be diminished. Continued high
moisture content suggests efficient rain rates and the
possibility for isolated areas of flooding.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
Lingering showers and embedded thunderstorms on Friday will taper
off from the west through morning and into early afternoon as the
mid level short wave moves off to the east. A west to northwest flow
pattern will then set up aloft heading into the weekend and remain
in place across the region through the first part of next week.

Surface high pressure over the northern Plains will nose down into
the Ohio Valley and then slowly shift southeast into the southeast
US through Monday. This will result in dry but cool conditions
across our area for Saturday through Monday. Daytimes highs will be
in in the 50s to lower 60s with overnight lows down into the 30s.
There will be the potential for some frost conditions both Saturday
and Sunday nights.

Mid level energy will drop southeast into the region Tuesday into
Wednesday, bringing the next chance for some showers and perhaps a
thunderstorms Temperatures will moderate a bit with highs both days
in the 60s.

&&

.AVIATION /02Z THURSDAY THROUGH MONDAY/...
Storms have moved east of the area and wind gusts will decrease
shortly after sunset. Winds remain out of the west, around 10
knots through the overnight hours, decreasing to around 5 knots
near the Tri-State. All sites should remain VFR overnight...
with that being said, there is a signal for some weak, patchy
fog. However, chose to not include in TAFs at this time since
VSBYs look to remain above 6SM.

Patchy cumulus linger through the area Thursday with winds
shifting to out of the south. High clouds begin to move in near
the end of the TAF period ahead of the next system.


OUTLOOK...Showers and thunderstorms with MVFR CIGs/VSBYs are
possible Thursday evening into Friday. Wind gusts around 30
knots are possible Friday.
