Area Forecast Discussion
National Weather Service Wilmington OH
957 PM EDT Tue Jul 1 2025

.SYNOPSIS...
High pressure moves into the region and the area dries out.
Temperatures return to near normals and humidity values will
decrease through the rest of the working week. A warming trend
arrives by the weekend, with a return of muggy conditions.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
10PM Update...
Cold front continues to slowly work its way through our CWA. A few
isolated showers exist near the boundary. Thunder coverage is
decreasing as instability wanes with the loss of diurnal heating, but
a stray lightning strike is possible with these showers.

Previous discussion --->
Ridging and surface high pressure move into the Ohio Valley region
through the overnight hours. Mass subsidence will allow for clearing
skies and light winds. Given the recent rainfall and antecedent moist
soil conditions, we are seeing a signal for fog during the overnight
into early morning hours on Tuesday. Strongest signal is in
central/eastern Ohio and northern Kentucky into the Appalachian
region. However, wouldn`t be surprised to see patchy fog elsewhere,
especially near areas with ample foliage/grass.

Clear skies combined with CAA will drop overnight temperatures to the
mid/low 60s.

&&

.SHORT TERM /WEDNESDAY NIGHT/...
Clear skies start the day on Wednesday but cu will build in
throughout the afternoon hours. High pressure remains in control and
dry conditions continue- afternoon dew points in the low to mid 60s
with daytime high temperatures reaching the mid 80s.

Overnight, we remain quiet and dry. Lows fall to the mid 60s.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
While ridging centered in the central CONUS dominates the region
beginning Thursday, portions of Ohio are more dominated by NW flow,
so some chances for scattered showers/isolated thunderstorms
generally along/north of I-70 Thursday and Friday afternoons in
diurnal instability. But with the ridge building in, the region will
trend overall toward a drier pattern, but with increasing
temperatures. Thursday starts off with mid/upper 80s, with
increasing temperatures each day getting into the low to mid 90s by
the weekend. There`s some uncertainty with whether or not surface
dewpoints will bring heat index values into the upper 90s, as well
as potential cloud cover increase by especially Sunday. Nonetheless,
HI values could approach mid/upper 90s Saturday/Sunday, depending
upon strength of the ridge and cloud cover with approaching
shortwave especially on Sunday.

As the ridge shifts off to the SE CONUS by Monday, some differences
in solutions on the breakdown itself and the potential strength and
timing of a trough through the central/lower Great Lakes. Storm
chances increase late Sunday and especially into Monday/Tuesday,
with temperatures settling into more seasonal values in the mid-
upper 80s.

&&

.AVIATION /02Z WEDNESDAY THROUGH SUNDAY/...
Cold front continues to slowly push through the terminals this
evening. An isolated shower could move across any of the terminals
still (KDAY less likely given the front has passed them), but the
threat remains isolated enough to not warrant a mention in the TAF.

Skies become mostly clear tonight, which will result in fog
development. Hardest hit location will be KLUK, but most terminals
may observe MVFR reductions at a minimum.

VFR cu development possible Wednesday afternoon. Winds remain light
out of the northwest through the taf period.

OUTLOOK...No significant weather is expected at this time.
