AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
648 AM EDT Thu Aug 26 2021

.SYNOPSIS...
A chance for showers and thunderstorms will continue at times
through the weekend as a warm and humid airmass remains in place
across the Ohio Valley region.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Isolated thunderstorms across Pike and Scioto counties have
been gradually dissipating and expect this trend to continue in
the very near term. Isolated to scattered thunderstorms are
continuing to push slowly east across Illinois and Indiana and
now into portions of far northwest Ohio. These have been
generally weakening through the early morning hours and are
associated with some mid level energy, with a broad circulation
evident on radar, centered along the central Illinois/Indiana
border. Meanwhile, some low clouds and fog have developed across
central portions of our area early this morning with some
locally dense fog noted on area webcams. Not sure how widespread
the dense fog will end up being with some mid and high level
clouds continuing to move in from the west. For now will cover
with an SPS and continue to monitor over the next couple of
hours.

The activity off to our northwest is forecast to gradually
weaken through the mid morning hours, but suppose some of this
may still sneak into our far northwest later this morning. Then
as we destabilize through late morning and into this afternoon,
expect scattered showers and thunderstorms to develop as the
mid level energy off to our west pushes slowly east into our
area. Temperatures today could be a little tricky once again,
with the potential for some debris clouds across the area this
morning and the chance for additional showers and thunderstorms
into this afternoon. Will generally go with highs in the upper
80s to near 90 degrees. This will combine with dewpoints into
the lower 70s to create heat indices in the 95 to 100 degree
range at times this afternoon.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
Will allow for showers and thunderstorms chances to gradually
taper off this evening with partly cloudy skies overnight. Lows
tonight will be in the upper 60s to lower 70s. Warm and humid
conditions are expected again on Friday with highs in the upper
80s to around 90 degrees. As we destabilize through the day,
expect to see the potential for isolated to scatted thunderstorm
development once again as some weak mid level energy moves over
the top of the mid/upper level ridge in place across the
Mid Atlantic states.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Other than a few scattered showers or thunderstorms weakening into
the evening hours, Friday night is mostly dry as diurnal activity
decreases. Broad scale pattern remains unchanged for the weekend as
surface/mid-level high pressure are in place over the eastern CONUS.
Warm and muggy conditions are forecast throughout the weekend with
diurnal enhancements to showers and thunderstorms anticipated for
both days.

Moving into early next week, geopotential heights begin to decrease
in response to a progressive trough moving into the Great Lakes
region. High temperatures decrease closer to normal values, but
chances for showers and thunderstorms persist as a surface cold
front approaches the Ohio Valley. Chances for precipitation are
elevated across the entire area for Monday with the progression of
the front moving slowly southward throughout the day. Thunderstorm
coverage decreases during the evening hours, however, chances
continue through the overnight as the front begins to stall.

Uncertainty increases quite significantly entering Tuesday and
through Wednesday as the influences of a potential tropical system
and stalled front could lead to different outcomes from what is
currently forecast. As the tropical system becomes better organized
in the western Caribbean Sea and eventually the Gulf of Mexico,
track forecasts will improve, increasing confidence for potential
local impacts. As is sometimes the case, landfalling tropical
cyclones along the Gulf Coast tend to curve eastward upon reaching
the mid-latitudes. Long range model guidance is hinting for the mid-
level high that has persisted over the Mid-Atlantic coast to steer
the remnants up the Mississippi River Valley before turning them
eastward into the Ohio/Tennessee Valleys. The weakening of the ridge
and the progression of another trough moving into the Midwest are
the primary factors for the ultimate track. Regardless of the exact
track, the stalled front and above normal PWATs favor continued
chances for showers and thunderstorms both Tuesday and Wednesday
with temperatures generally in the low to mid 80s.

&&

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
Areas of low clouds and fog are persisting across central Ohio
as well as in some of the river valleys elsewhere across the
area. This will lead to the possibility of some IFR conditions
at KLUK,KCMH and KLCK at the start of the TAF period before
conditions begin to improve through mid morning. Otherwise, an
upper level disturbance will push slowly east into the area
through this afternoon. As the airmass destabilizes through the
afternoon, expect to see a chance for some showers and
thunderstorms develop. Will generally cover this threat with a
VCSH through the afternoon hours. Any activity should taper off
this evening with some fog development possible later tonight,
especially in the river valleys.

OUTLOOK...Thunderstorms are possible through Monday.
