AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
148 AM EDT Tue Apr 30 2024

.SYNOPSIS...
Showers and some thunderstorms will occur tonight into Tuesday
ahead of a cold front that will cross the region. High pressure
will then build in for the middle of the week with the return of
much above normal temperatures. Another cold front will move
towards the area on Friday bringing the next chance of showers
and thunderstorms.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Widespread showers with a few embedded thunderstorms will
continue to overspread the area through late evening and into
the early morning hours. These are in associated with a weak mid
level short wave moving through the Ohio Valley and ahead of an
approaching weak cold front. Expect a decreasing trend in any
thunderstorm activity over the next few hours as we continue to
lose the daytime heating, with mainly just rain showers through
the rest of the night. Pcpn will begin to taper off from the
west later tonight as the cold front moves into the area.
Overnight lows will range from the upper 50s northwest to the
lower 60s in the southeast.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM WEDNESDAY/...
Showers and possibly some thunder will still be ongoing at the
beginning of the period. This will move off to the east in the
morning. The cold front will continue to lag the main area of
precipitation and it is possible that there could be a bit of
further development along the front before it finally clears the
forecast area as well. Clouds will decrease during the afternoon
and into the evening. High pressure will build in behind the
front and skies will eventually become clear.

Highs will be in the lower to mid 70s with lows Tuesday night
falling into the upper 40s to lower 50s.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
Mid-level ridging develops on Wednesday and amplifies on Thursday
ahead of the next digging shortwave trough over the Central Plains.
This ridging along with a return southwesterly flow will allow
temperatures to return to above normal levels.

A frontal system ahead of the trough will progress into the Great
Lakes and Ohio Valley Friday. Showers and storms will be likely into
Friday night depending on the timing of the front. Guidance
continues to diverge heading into the weekend, with uncertainty on
how quickly the frontal precipitation clears our area Saturday.

By Sunday the first system will likely have cleared our southeast
with a secondary front pushing through the Great Lakes. There may
not be much moisture with this reinforcing front, so have included
just a low chance of showers... which are maintained into
Monday.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
An axis of widespread showers with a few embedded thunderstorms
will slowly overspread the TAF/s early this morning from the
west ahead of an approaching cold front.

As marginal instability wanes thunder chances will continue to
taper off, so have omitted the mention of thunder at any TAF
site.

Showers will begin to taper off from the west as the cold front
moves in toward sunrise. VFR cigs will drop into MVFR with a
brief period of IFR possible toward sunrise (mainly across KDAY).
MVFR cigs to continue through mid morning before scattering out
with VFR conditions developing this afternoon. VFR conditions
to continue into tonight as weak high pressure builds in.

OUTLOOK...Thunderstorms and MVFR cigs possible Friday afternoon
into Saturday.
