Area Forecast Discussion
National Weather Service Wilmington OH
114 PM EST Wed Jan 8 2025

.SYNOPSIS...
Arctic air mass remains in place across the Ohio Valley, with
the coldest temperatures expected before the weekend. A southern
tracking low pressure system will bring additional snow
accumulation to the region Friday into Saturday. Temperatures
trend a few degrees milder through the weekend before another
surge of colder air leads to a drop in temperatures next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Snow flurries and snow showers are expected today into tonight
before starting to taper off. Expect some snowfall accumulations
across northern portions of the region. There is some question
on how quickly and how far clouds will clear out. Dropped
temperatures more where there is more potential for clouds to
clear out tonight. Also focused the cold weather advisory across
those portions as well.

&&

.SHORT TERM /THURSDAY/...
Quiet and cold conditions will be in place for Thursday. Cold
weather advisory continues into Thursday morning with wind chill
values of negative 5 to negative 12.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Surface high pressure will be shifting off to the east through
Thursday night. With the snow pack still in place and light winds,
temperatures will drop off quickly in areas that remain clear.
However, clouds will be on the increase from the west through the
night ahead of the next system and this will allow for temperatures
to eventually level out or even rise some. For now, will range
lows from near zero in the far east to around 10 in the far west but
this will be dependent on the exact timing of the clouds.

An upper level trough will move out of the Mississippi Valley
and across the Ohio Valley Friday into Saturday. Some
embedded southern stream energy will lift northeast toward our area
and this will lead to an increasing chance for snow from the
southwest during the day on Friday, with widespread snow expected by
later Friday afternoon into Friday evening. The snow will then
taper off from the west later Friday night. Some accumulating snow
can be expected with amounts generally in the 1 to 3 inch range.
Temperatures will remain below normal with highs on Friday in the
mid to upper 20s.

Mid level ridging will push east across the Ohio Valley Saturday
into Sunday, leading to mainly dry conditions. Highs on Saturday
will again be in the mid to upper 20s with highs on Sunday in the
upper 20s to lower 30s. A mid level short wave will push east across
the region early next week, bringing a chance of snow Sunday night
into Monday and a reinforcing shot of colder air by Tuesday. Highs
on Monday will be in the upper 20s to lower 30s, cooling to highs
in the upper teens to mid 20s for Tuesday.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Flurries or light snow showers will be around at times through
the evening hours and part of the overnight. Vsbys might be
reduced at times with some of the snow shower activity around
KCMH and KLCK this evening. MVFR cigs will also be possible at
times, then gradually becoming VFR. Clouds will linger longer
around KCMH and KLCK. Winds will generally be around 10 knots or
less, however isolated higher values cannot be ruled out during
the day and evening hours.

OUTLOOK... MVFR to IFR ceilings and visibilities possible
Friday night into Saturday and then again Sunday night into Monday.
