AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
731 PM EDT Mon Jun 17 2024

.SYNOPSIS...
Hot and humid air over the region will bring another day of
scattered thunderstorm activity on Tuesday afternoon. Slightly
drier air will make an appearance over the region on Thursday
but the hot airmass will remain entrenched through at least the
end of the work week, possibly into the weekend.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
The Heat Advisory remains in effect through Friday evening.

Scattered thunderstorm activity this afternoon and evening will
quickly diminish with the setting sun. Lingering cloud cover
will be slower to decrease overnight with some higher AS clouds
expected to the prevalent sky cover.

Overnight lows in the low to mid 70s will be warmest in west
central Ohio and coolest in the southeast and Hocking Hills.
This will not provide any relief from the ongoing heat wave.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
Another hot and muggy day is in store for Tuesday with heat
indicies peaking near 100 degrees for most locations.

The area of high pressure will continue to expand westward
resulting in a slightly lower chance of storms in the afternoon
and early evening.

Min temperatures will be a little warmer than what`s expected
tonight, closer to 75 for most of the CWA.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
With a large and slow moving area of high pressure centered to
the east, heat continues to be the main concern during the long
term. For Wednesday through Sunday, highs in the mid and upper
90s combined with dewpoints around 70 will produce peak apparent
temperatures ranging from 100 to 104. Overnight lows in the 70s
will only provide limited help. Based on those forecast model
predictions, our office has issued a heat advisory that is in
effect through Friday. Extending the heat advisory through next
weekend appears strongly possible. At some point, if apparent Ts
are forecast to go above 104, we will need to upgrade to an
excessive heat warning. There is relief on the horizon when an
upper trough and cold front bring an end to the extreme heat
next Monday, with highs retreating to the mid and upper 80s.

Chances for abatement from the heat due to precip appear to be
low. There is a chance for a few thunderstorms on Wednesday, and
again on Sunday ahead of the cold front. A better chance for
measurable precip will be on Sunday night and Monday surrounding
the cold frontal passage.

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
-- Changed Discussion --
A few spotty SHRA/TSRA continue to percolate about the local
area and coverage should continue to wane toward/past sunset.
However, it may not be an entirely dry overnight across the
region, with indications for additional very spotty/ISO activity
possible through daybreak, especially near KILN/KCMH/KLCK.
Additional diurnally-driven activity will sprout about the
region again by the afternoon, but coverage should, in general,
be more ISO opposed to SCT in nature. Therefore, have opted not
to include even a VC at this juncture.

Light southerly winds at 5-8kts or less will be maintained
through the period with some VFR Cu redevelopment/expansion
by/after 15z. Some BR will be possible near river valleys and in
locales that received appreciable rainfall this afternoon. As
such, MVFR VSBYs will again be possible at KLUK in the several
hours around daybreak.

OUTLOOK...No significant weather expected.
