AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
340 PM EDT Mon Jul 8 2024

.SYNOPSIS...
A weak trough will develop across the area. This is ahead of the
remnants of Beryl which are forecast to track from southwest
Indiana to Lake Erie Tuesday night and Wednesday. High pressure
will then build in for Thursday and Friday.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Diurnal cumulus will dissipate with the loss of heating.
Beyond that will just see high and perhaps some mid clouds
continue to stream northeastwards across the region. These
clouds may become thicker during the overnight hours. Lows will
be in the upper 60s to lower 70s.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
Inverted trough across the region at the beginning of the period
will become more pronounced during the day as the remnants of
Beryl move northeast. This boundary will become an effective
warm front and lift as the center of the low circulation moves
into eastern Indiana by daybreak Wednesday. With backed winds
and gradually increasing flow, hodographs will take on a
favorable orientation. In addition, LCLs are forecast to lower
as the atmospheric column moistens. It may be too moist to have
much instability or thunder, but conditions could become
favorable for tornadoes, as can typically happen on the eastern
side of tropical remnants. This is highly conditional, but will
have to be watched closely heading into Tuesday afternoon and
evening.

Expect to see showers and some thunderstorms develop into the
forecast area on Tuesday afternoon and become widespread
generally north and west of I-71 Tuesday night. South and east
of there precipitation may be more transient and not necessarily
occurring everywhere.

Given the track of the low center, widespread heavy rain is not
a substantial concern, especially given the generally dry
antecedent conditions. But with tropical moisture, cannot
discount the potential for locally heavy rainfall.

Expect a relatively strong gradient in temperatures on Tuesday
with highs in the lower 80s in eastern Indiana but still
reaching the lower 90s in south central Ohio and northeast
Kentucky. Lows will be in the upper 60s to lower 70s again.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Gusty winds will be likely on Wednesday as the remnants of Beryl
move through the region.  While there are still some minor
differences on location of the low, in general it looks to come near
northwestern portions of the forecast area before continuing to move
to the northeast.  Showers and a few thunderstorms will be possible
as the system moves through on Wednesday.  Temperatures on Wednesday
will be cooler closer to the low across northwestern portions of the
region.  Have high temperatures ranging from the lower 70s across
the northwest to middle 80s across the southeast.

On Thursday the temperatures will be a little more uniform with
highs in the low to middle 80s.  Some additional isolated
thunderstorms are possible on Thursday as a weak disturbance moves
through.

Warm temperatures will be in place the remainder of the long term
with highs in the 80s to lower 90s.  Heat index values by Monday
will approach advisory levels in some spots, however will be
dependent on if precipitation will hold off. Friday looks dry at
this time. With the heat and humidity over the weekend there will be
off and on chances for thunderstorm activity. There has been some
variability in the models with keying in on specific times and
therefore limited precipitation chances to the chance category.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
Cumulus across the region will dissipate towards 00Z with the
loss of heating. This will leave just high and mid clouds
streaming across the area through the rest of the forecast
period. Higher clouds may be thin enough to allow for some
visibility restrictions to develop at KLUK overnight, although
confidence in this occurrence is only medium. Otherwise VFR
continues to prevail. Winds will remain light.

OUTLOOK...MVFR to IFR ceilings and MVFR visibilities possible
Tuesday night into Wednesday.
