Area Forecast Discussion
National Weather Service Wilmington OH
113 PM EST Wed Dec 10 2025

.SYNOPSIS...
A strong system will move through today bringing with it a transition
from rain to snow showers, gusty winds, and cooler temperatures.
A couple of systems Thursday night into Friday morning and Saturday
into Saturday night are both expected to bring accumulating snow to
the region. Very cold air will filter in bringing near or below zero
wind chill values both Sunday and Monday morning.

&&

.NEAR TERM /THROUGH TONIGHT/...
A gap in precip behind an enhanced band with wind gusts from 30-40kts
currently near KCMH to just east of KLUK. Falling temperatures
working into the forecast area, with a rain/snow shower mix with wind
gusts to 35kts in the cold air advection wrap around moisture. Wind
gusts 30-35kts are more likely now behind the main frontal boundary,
with a changeover to all snow showers after 4pm working east through
the area. Moisture does diminish pretty quickly, but still the
potential for a very light coating of a tenth or two of snow
especially on elevated surfaces as the evening progresses. Continued
the SPS for winds and slick surfaces through 00z for now, as well as
expecting to continue mention of these in the HWO.

Strong CAA and diminishing wind gusts overnight under cloudy skies as
the upper trough pivots through the region. Overnight lows in the
lower 20s north to upper 20s south. Moisture becomes more sparse
overnight, so snow showers will diminish in coverage. Wind gusts will
diminish overnight, but winds remain slightly elevated near 10mph.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY/...
A brief lull in precip expected on Thursday, though per several of
the CAMs, continued with at least a slight chance of snow showers in
central Ohio in NW flow bringing a fetch off of Lake Michigan. With
the continued NW flow/strong CAA, much below normal daytime highs in
the upper 20s to lower 30s.

For Thursday night, chance for snow ramps up especially near/after
midnight in eastern Indiana, exiting the area near/after 15z, with
the prime accumulation potential time from ~06z-12z. The best area
of moisture of 0.2-0.3" is expected generally across SE Indiana
through the Cincinnati Tri state and eastward to the lower Scioto
valley, which has shifted the probability of exceeding both 1" and
2" of snow a little further south, with prime location extending
from near Richmond, IN and southeast toward Hamilton/Cincinnati Ohio
and into far northern KY. This remains the prime area with the
greatest probability of 2"+ of snow accumulation by 15z.

Lesser chances of these thresholds occurring in Central Ohio. The
system is fairly progressive, and some slight downward adjustments
made from the NBM SLRs to a little closer to the WPC SLRs, generally
11-13:1 across the south, and 13-16:1 closer to I-70. The resulting
snow potential will have a pretty tight gradient across the region.
Another possibility/uncertainty which could cut a bit into snow
totals across the south is a warm air push beginning near 12z, with
temperatures rising through the mid 30s across the south in the
12-17z timeframe. So a mix with or complete changeover to rain is
possible as the core area of precip is winding down/heading east.

Bulk of the accumulating snowfall will shift eastward after 15z
Friday, with colder/dry air funneling into the Ohio Valley for the
weekend, with high confidence in these bitterly cold temperatures.


&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A brief period of cold and dry weather is expected from Friday night
through Saturday morning before the next system arrives later on
Saturday.

By the second half of Saturday, an arctic front and upper level
disturbance will be diving toward the Ohio Valley from the
northwest. Just ahead of these features, an area of snow develops
and moves across the area starting Saturday afternoon/evening before
pulling east by Sunday morning. A widespread 1-3 inches are
moderately likely although the heaviest axis of snow has yet to be
resolved. There are also some indications that snow rates and ratios
could be fairly high north of I-70 with vorticity max moving in along
with the arctic boundary.

Bitterly cold air settles in from Saturday night through Monday
morning. Overnight lows drop into the single digits for many
locations along with wind chills below zero Sunday and Monday
mornings. High struggle to get out of the teens.

Temperatures moderate to start next week.

&&

.AVIATION /18Z WEDNESDAY THROUGH SUNDAY/...
Visibility restricting rain pushing east of all of the TAF locations,
with gusts from 25-35kts possible through about 22z before slowly
diminishing. After a lull in precipitation, wrap around moisture in
the form of RASN to work eastward and gradually change over to all
-SHSN. Have generally handled this as tempo MVFR visibility
 restrictions especially from 20-04z, with Prob30 MVFR visibility
 restrictions in lingering snow showers to about 06-08z. Cigs will
 generally be MVFR, with occasional IFR possible in snow showers.

After 12z, while snow showers may linger toward KCMH/KLCK,
probability is pretty low for vsby restrictions at this time.
Lingering MVFR CIGs possible through the period.

OUTLOOK...MVFR to IFR conditions possible Thursday night through
Saturday night.
