AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
211 PM EDT Thu Sep 19 2024

.SYNOPSIS...
High pressure will remain in place across the region through
the weekend. This will lead to mainly dry and continued warm
conditions. A frontal boundary will move into the area early
next week, bringing somewhat cooler temperatures and a chance
for showers.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
No significant changes needed with the morning update. Weak
surface high pressure and mid- level ridging will bring another
day of warm and dry weather. Winds will be light out of the
north. Efficient mixing and dry soils will cause dewpoints to
fall off into the 50s this afternoon.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
The mid level ridge axis will begin to flatten out tonight into
Friday as some weak mid level energy rides over the top of it.
This will likely lead to some increase in clouds across our
northwest through the afternoon but it looks like any pcpn
associated with the short wave should remain off to our
northwest through the daytime period. Lows tonight will be in
the mid 50s to lower 60s with highs on Friday again in the
upper 80s to possibly lower 90s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
CAMs show a decaying complex of showers/storms Friday night moving
in from the northwest. Some of the remnants may bring some showers
into our far western counties Friday night, but model soundings do
show a pretty dry boundary layer that will have to be overcome. Will
keep a slight chance PoP mention in the grids, but not overly
confident in measurable precip from this.

Seasonably warm conditions persist throughout the weekend as subtle
H5 ridging builds in. Many locations will observe highs in the upper
80s Saturday and Sunday, with some lower 90s mixing in as well. This
is 10-15 degrees above seasonal normals.

By Sunday night, the H5 ridge begins to break down as an elongated
trough starts to propagate through the Midwest region. This synoptic
feature may offer the best chance for widespread measurable precip
across our fa in quite some time. In fact, several ensembles are
even showing potential for near or greater than 1" of measurable rain
from Monday - Tuesday. Will have to monitor trends to see how this
system pans out, but there are increasing signals for decent
rainfall footprint.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
VFR conditions will prevail across most of the TAF sites through
the period under weak high pressure. Mostly clear skies and
light winds will allow river valley fog to develop, mainly
affecting LUK toward sunrise.

Scattered showers and perhaps a storm may develop toward the end
of the 30-hour CVG forecast period, but chances are too low for
a mention in the TAF at this time.

OUTLOOK...Hazardous weather is not expected.
