Area Forecast Discussion
National Weather Service Wilmington OH
1119 AM EDT Wed Aug 20 2025

.SYNOPSIS...
Cooler air will filter into the area through Thursday night, with
near to slightly below average temperatures expected while expansive
cloud cover lingers until Thursday evening. A brief warmup evolves
Friday into Saturday. By Sunday through early next week, much cooler
and drier air will settle into the Ohio Valley, leading to a
prolonged period of abundant sunshine and below normal temperatures
through the first half of next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
High pressure moves into the Upper Great Lakes this afternoon into
tonight. Relatively cool, moist northerly flow southeast of the high
keeps clouds in place through the period. After peaking in the 70s
across most locations late this afternoon, temperatures drop back
into the 60s tonight. A stray shower or sprinkle cannot be ruled out
in the sprawling stratocumulus fields.

&&

.SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/...
Surface high pressure over the Great Lakes remains in place Thursday
and Thursday night. Northerly flow persists along with fairly
abundant cloud cover which limits highs to the upper 70s for most
locations outside of southern Ohio and northern Kentucky. Dew points
do not dry out much and stay in the middle 60s despite northerly
winds. Skies may finally start to scatter more late Thursday
afternoon although this remains fairly uncertain due to moisture
being in place. With winds relaxing Thursday night and some clearing
being possible, forecast lows drop a few degrees cooler into the
middle to lower 60s.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
A west to east oriented mid level ridge axis nosing into the Ohio
Valley will weaken through the day on Friday. Temperatures will be
seasonable with highs in the mid to possibly upper 80s.

An upper level low pressure system will move across the northern
Great Lakes through the weekend, helping to carve out a broader
trough across the central and eastern CONUS heading into next week.
Highs on Saturday will range from the mid 80s in the northwest to
around 90 degrees in our far southeast.

A cold front associated with the upper level trough will move
through the area Saturday night into Sunday. Moisture is fairly
limited so expect any shower activity to be minimal. Behind the cold
front, a much cooler airmass will settle into the region with below
normal temperatures expected through the first part of the week.
Highs on Sunday will range from the mid 70s northwest to the mid 80s
southeast with highs Monday through Wednesday only in the 70s across
the entire area.


&&

.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...
Widespread MVFR ceilings may lift to a VFR cloud bases this
afternoon due to diurnal mixing. Ceilings are then expected to lower
back into the MVFR category after 0600z tonight from northeast to
southwest. Ceilings are likely to scatter and lift to VFR once
again around 1800z Thursday.

Northerly/northeasterly winds from 5-15 knots persist.

OUTLOOK...MVFR CIGs are likely, with IFR CIGs possible, through
Thursday.
