The episode as NWS PBZ wrote it up.
Low pressure tracked up the Eastern Seaboard from the Carolinas on January 22nd to the New England coast on the 23rd. Southwest flow and jet ascent created widespread precipitation across the Upper Ohio Valley from the afternoon of the 22nd to the morning of the 23rd. Most of the snow accumulation was focused in areas north of I-70 in eastern Ohio and southwest Pennsylvania, save for some accumulations in the usual ridge locations.

National Weather Service Pittsburgh PA
651 AM EST Sun Jan 22 2023
.SYNOPSIS...
Snow and rain is expected this afternoon, changing to all snow
tonight and continuing into Monday as a low pressure system
passes to the southeast. The next winter system will arrive mid
week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
The upper trough will remain fairly progressive while deepening
today, passing over the Upper Midwest. Cyclogenesis at the sfc
will spawn a new sfc low center over the Carolinas late today,
with the center moving rapidly NE reaching the southern NJ coast
last this evening. With sfc forcing weak, as the low placement
remains well southeast, the Upper Ohio River Valley will rely on
jet ascent within SW flow ahead of the trough axis to promote
widespread precipitation this afternoon and evening.
Any warm advection within the SW flow is expected to be somewhat
negated by wet-bulbing as top-down moistening cools the dry
near sfc layer with precipitation onset. This should keep any
elevated warm layer near the 0 degree isotherm, while enough
diurnal heating should keep area sfc temperature above freezing.
The result effect on precipitation will depend on the distance
from the surface low. Locations further north and west, will
likely see all snow, while locations further south and east will
see mostly rain, and those in the middle will see a mix with
precipitation changing back and forth throughout the day.
Accumulations are expected to generally be light (less than
advisory criteria) given lack of real cold air, strong forcing,
and moisture/lift not extensively existing through the DGZ. Snow
accumulations will be focused across eastern OH/northwest PA
late this afternoon and evening.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
Precipitation will become all snow tonight as cold advection
ensues behind the exiting surface low. There are signs of a
deformation zone near/NW of Pittsburgh around the Monday morning
commute that could also act to enhance rates and cause brief
banding of residual snow showers. It is unlikely this will lead
to advisory level accumulations or snow squalls, it could make
for some nuisance travel in areas impacted by this enhancement.
Snow showers will dissipate through Monday afternoon as
subsidence with shortwave ridging develop as the upper trough
becomes further removed east of the region.
Seasonable temperature and generally dry conditions are likely
Tuesday within quasi-zonal flow, though a passing shortwave
trough farther north could provide enough lift for a few light
snow showers/flurries near the I-80 corridor.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Confidence is high in precipitation chances increasing starting
Wednesday morning in response to a negatively-tilted trough
lifting northeast from the TX panhandle. Potential impacts vary
notable between various ensemble guidance and will ultimately be
influenced by the regions positioning relative to the sfc low
center track and elevated warm layer.
An active weather pattern is likely to continue thereafter as
additional low pressure systems cross the region within
broad Great Lakes troughing.
&&
.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
A shortwave within an approaching trough will spread
precipitation northeast late this morning through the afternoon,
causing rapid deterioration to MVFR/IFR restrictions. Varying
thermal profiles creates uncertainty with precipitation type,
but rain will be favored in lower level terminals while some
sort of mix (or all snow) will be favored in higher elevations
and around KZZV/KFKL/KDUJ.
Potential band of snow may develop from eastern OH to northwest
PA, which may create more drastic vsby restrictions in heavier
snowfall rates up to 0.5"/hr.
A transition to all snow and more showery (on and off) activity
is expected overnight amid cold advection as sfc winds shift NW
with exiting of sfc low and as the upper trough begins to cross
the area. Further cig reductions makes it likely that all
terminals will see IFR and localized LIFR that may have a few
hours that flirt with airport mins (approx timing if it occurs
would be from 05z-09z).
.OUTLOOK...
Upper troughing and cold NW flow should maintain restrictions
(with some lifting through diurnal mixing) with snow showers
Monday, with accumulations greatest in the higher terrain.
Generally dry weather should create a window of VFR conditions
Tuesday before restrictions return with widespread precipitation
as low pressure system approaches Wednesday.
