What forecasters said that day

The local office's own words before this winter weather advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Cleveland, OH wrote its last area forecast discussion before this winter weather advisory went out at Jan 30, 12:51 AM EST, 2 hours 33 minutes earlier.

Area forecast discussion, Jan 30, 12:51 AM EST, 2 hours 33 minutes before
Area Forecast Discussion
National Weather Service Cleveland OH
1251 AM EST Sat Jan 30 2021

.SYNOPSIS...
High pressure will be across the region tonight and Saturday.
Then all eyes turn to the Oklahoma panhandle where low pressure
will develop and move to the Ohio Valley for Sunday. The low
will transition off of the east coast Monday, but a trough will
linger across the eastern Great Lakes.

&&

.NEAR TERM /THROUGH TODAY/...
Update...
The near-term forecast remains valid. No updates appeared
necessary early this morning.

Previous Discussion...
Flurries across northeast Ohio have just about ended and
significant breaks in the overcast have begun to develop.
Further east enough moisture is still around with a flow off of
the lake to continue to squeeze out more light snow showers
tonight. As far as temperatures are concerned for
tonight have colder temperatures than the past few nights. With
clear skies and near calm winds, will allow for better
radiational cooling.

Saturday will be a transition day as the high shifts east and
surface flow comes around to the southeast. Any early breaks
in the cloud cover will be met with the slow and steady increase
and thickening of mid and high clouds with the approach of low
pressure originating across the Oklahoma panhandle and reaching
Missouri by the end of the day Saturday. Even with a cool start,
temperatures will rebound as the beginning of warm advection
begins to take place. Will stick highs in the lower 30s across
OH and upper 20s in NW PA. Any lingering flurries in NW PA will
wrap up in the morning.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
All attention for the forecast this afternoon is for the incoming
low pressure system that will move through the Ohio Valley on
Saturday night through Monday. Overall, not much has changed for the
short term forecast period in regard to snowfall timing and snow
total forecasts. At this time, have continued letting the forecast
speak for itself with a long period of snow across the region with
totals of 3 to 8 inches over 60 hours spanning Saturday night
through Monday night. The highest snowfall amounts still remain in
Northwest and North Central Ohio, largely Toledo to Wooster and
southwest. Winter Weather Advisories could be issued overnight, as
we get closer to this event, to highlight a period of better snow in
this region early Sunday morning.

An upper trough over the central CONUS will support developing low
pressure over the lower Missouri Valley on Saturday evening. A warm
front will extend through the Ohio Valley ahead of the front and
linger just south of the forecast area. The low will track east
along the front Saturday night through Sunday night. The forecast
area remains largely on the cold side of the system and initial
precipitation type will be snow on Saturday night and Sunday with
temperatures below freezing through the entire atmosphere. A good
push over snow is expected to push across the forecast area
overnight Saturday into Sunday with a small vorticity max that will
move through the approaching upper trough. While lift and moisture
are present with this system, the tricky part of the event is the
snow-to-liquid ratio. While temperatures are below freezing, low
level temperatures aren't that cold and we don't get the better
moisture and lift to align to have high SLRs. With that, snow will
not be as efficient to build up snow accumulations, rather snow will
be heavier, wetter, and less efficient and in turn, have less
accumulation with the amount of QPF in the forecast. As the low
pressure system continues across the region on Sunday, a wedge of
warmer air does try to push north to allow for some wintry mix or
even rain on the fringe southeastern portions of the forecast area.
This will allow eat at snowfall totals depending on how far north
this warmer air gets, but generally speaking, most folks will stay
as snow. The low pressure system weakens across the area on Sunday
and the better jet energy passes along to the East Coast system. A
residual trough will remain in place and snow showers will persist
through Monday. Again, we aren't all that cold to have robust snow
showers so have generic 1 to 2 inches of snow for the end of the
period. Temperatures through the period will be near seasonal
averages.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
Snow should taper through the day on Tuesday as the residual
surface trough weakens across the area. There could be some
focus for snow in the typical lake effect snow regions as colder
air enters, but drier air also enters quickly so it would be
shallow, low intensity snow. The 850 mb ridge and surface high
pressure enter for Wednesday and all snow will be done. The next
system approaches for Thursday and Friday and we remain on the
warm side of the system for Thursday and temperatures could rise
into the 40s with rain. A cold front will pass through on
Friday and rain will change over to snow as more seasonable
conditions return.

&&

.AVIATION /06Z Saturday THROUGH Wednesday/...
At the surface, a high pressure ridge gradually exits our region
to the north and east as a developing low near the OK Panhandle
early this morning moves east-northeastward to near KSTL by
06Z/Sun. Winds trend calm or light and variable through about
15Z/Sat. Thereafter, regional winds should trend east-
southeasterly to southeasterly at about 5 to 10 knots.

Lake effect stratocumulus clouds and borderline VFR/MVFR
ceilings across far-northeast OH and northwest PA should linger
through this late afternoon or early evening while contracting
slowly in coverage. Lake effect snow flurries may affect KYNG
and KERI at times, but visibility will remain in the VFR range.
Otherwise VFR ceilings develop and lower gradually over the
region, generally from southwest to northeast, as the
aforementioned low approaches. Widespread light snow and
associated MVFR ceilings/visibility should begin overspreading
the region after 04Z/Sun. The snow and lower ceilings should
make it nearly as far northeast as a KTOL to KMFD line by
06Z/Sun.

Outlook...Periods of non-VFR with widespread snow are probable
Sunday night through Tuesday.

&&

.MARINE...
High pressure entering the region is allowing for winds to
relax across Lake Erie. Stronger northwest flow remains over the
eastern half of the lake and have Small Craft Advisories
through this evening. High pressure becomes centered across the
lake tonight into Saturday and flow will be lighter and more
variable. As high pressure shifts east on Saturday, southeast
then easterly flow will be favored. Low pressure will approach
on Sunday and pass south of the lake, increasing easterly flow
and another round of marine headlines are expected. With the
unfavorable easterly flow, there could be increases in water
levels over the western basin and lakeshore flooding could be an
issue as well. The low passes southeast of the area on Monday
as it merges with a coastal system and winds will become more
northeast on Monday and then north by Tuesday as a residual
trough lingers over the eastern Great Lakes region and suspect
marine headlines will continue into early next week. High
pressure will briefly return midweek for a quieter marine
weather day on Wednesday.
