What forecasters said that day

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

NWS Grand Rapids, MI wrote its last area forecast discussion before this winter storm warning went out at Jan 31, 3:48 PM EST, 8 minutes earlier.

National Weather Service Grand Rapids MI
348 PM EST Mon Jan 31 2022

LATEST UPDATE...
Marine

.DISCUSSION...(This evening through next Monday)
Issued at 349 PM EST Mon Jan 31 2022

- One more quiet night weatherwise

A storm is tracking well north of Michigan overnight. There is a
coupled jet feature with that storm. The jet core is passing over
Lake Superior so we will be deep into the warm sector of this
system tonight into Tuesday. Being currently in the right exit
region of that jet feature (mid level subsidence) I do not expect
any precipitation or even that much cloud cover. It will turn
breezy through. The mixing from the systems boundary layer winds
will keep the temperature from falling much tonight even with
minimal cloud cover.

- Rain Tuesday night

As that jet core moves east with the system tonight into Tuesday
we get into the entrance region of that jet (as it strengthens).
Not only that but a southern stream jet comes in phase with it
creating a coupled jet. This results in decent dynamic forcing
(lift with Gulf Moisture feeding into it). That creates an area of
precipitation precipitation from near Detroit to St Louis but mid
afternoon Tuesday. As the cold front trailing the system moves
east it undercuts the warm air so the rain will change to snow
overnight Tuesday. Could be some freezing rain just behind the
cold front.

The area of rain will track with the cold front at first but
during Tuesday night into Wednesday morning the jet created lift
will sustain the precipitation, deeper into the cold air. That
then starts our snow storm.

There is some question based on some of our HI RES models just how
far north the rain or rain to snow gets Tuesday night into
WEdnesday. The 12z and 18z run of the HRRR give GRR nearly NO
precipitation at all Wednesday. Areas south of a line from
Saginaw to South Haven would get over a 1/4 inch of qpf by 7 am
Wednesday. Other models disagree and have measurable
precipitation over the entire CWA. I would go with the idea that
south of that line it surely will precipitate. Near that line,
rain to snow, then snow is likely during Wednesday morning and
north of that (say north of route 20) I'd expect sprinkles early
Wednesday morning, changing to flurries by sunrise.

- Winter Storm Expected Wednesday into Thursday

We have upgraded the Winter Storm Watch to a Winter Storm Warning
for our southern row of counties since there is excellent
agreement with ensembles for many runs in a row in that area for
the developing wave on the trailing cold front to get far enough
north to bring over a foot of snow over 42 hour period (early Wed
to late Thu). The next row of counties north still looks to have a
high risk of 6 to 12 inches in that time frame but it's not for
sure there will be 8 inches in 18 hours (warning criteria for
heavy snow). We have let the Winter Storm Watch remain in effect
on those counties. The row of counties north of the watch is
really questionable as to if it will even snow at all (latest GFS
operational run) for whether there will be heavy snow even as far
north as Muskegon to Alma.

Just how far north the snow gets later Wednesday into Thursday is
a result of what happens to our jet exit region and how the
deepening trough just upstream interacts with it. There is still
uncertainty for those counties.

-Dry but cold Friday

The storm should be out of the area by Thursday evening. We get a
large arctic high to follow the storm Thursday night into Friday.
With the center of the high tracking over southern Ontario, north
of Lake Superior we get northeast winds so no lake effect in our
CWA. It will just be very cold. High will be in teens.

- Cold air prevails into the weekend

We will see a progression of Pacific shortwaves for the next week.
That will mean a series of clipper type systems. I would expect
some snow showers from time to time from these systems but timing
and location are questionable. One thing for sure, it will remain
cold.

&&

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1240 PM EST Mon Jan 31 2022

For the most part MVFR cigs prevail across SW MI and that does
make sense given the polar jet has not yet moved east of this
area. Typically the low clouds clear when we get on the
anticyclonic side of the polar jet. That should happen by mid
afternoon. I am thinking between 20z and 22z all of our TAF sites
should see the low clouds break up, leaving just some cirrus
clouds (from the polar jet) around.

Tonight the developing system gets closer to the area and that
will increase wind speeds. That will result in and elevated core
of strong winds (200/40kts) just about 2000 ft off the ground.

&&

.MARINE...
Issued at 346 PM EST Mon Jan 31 2022

I have continued the gale warning over the northern two marine
zones for tonight into Tuesday afternoon. Otherwise I have a
small craft advisory for the rest of the Near Shore from this
evening into Tuesday afternoon. The strongest winds will be over
the northern 1/3 of our Near Shore Waters from around midnight
through noon on Tuesday. Likely we will have to follow this with a
small craft advisory into Thursday.

This hazardous weather outlook is for portions of southwest Lower
Michigan.

.DAY ONE...This Afternoon and Tonight

No hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Rain is expected late Tuesday afternoon into Tuesday evening. The
rain will mix with then change go snow after midnight, early
Wednesday morning. There may be a period of freezing rain around
midnight as the colder air filters in. Snow is expected Wednesday
during the day but it will mostly be near and south of a line
from Alma to Muskegon. A storm system will develop on the front
Wednesday and track toward the Ohio Thursday. That will continue
the snow near and south of that same line. Snowfall amounts may
total more than a foot in the I-69 area but will be much less one
you get north and west of I-96. Areas near and north of Route 20
may see nearly no snow at all. Expect significant travel issues
Wednesday into Thursday near and south of I-96. Very cold air
moves in Thursday, resulting in wind chill values near to below
zero.
