LATEST UPDATE...
Discussion/Marine

.DISCUSSION...(Today through next Thursday)
Issued at 330 AM EST Fri Jan 7 2022

- Lakeshore Snow Showers into this Afternoon

The heaviest snow shower activity still looks to be confined to the
western halves of our lakeshore counties through the morning and
into early afternoon before diminishing. Significant snow
accumulations have likely been occurring underneath the dominant
band that has been passing over Big and Little Sable Points and
coming onshore across extreme western Allegan County and into
western Van Buren. Treacherous travel conditions have been observed
west of Paw Paw on I-94 which is where models have consistently
shown a max in omegas within the DGZ. For Ottawa and Muskegon
Counties, little occurred overnight as the band has remained
primarily offshore, but we are still expecting a slight jog to the
east through the early to mid morning hours (as is already occurring
in fact), bringing the western portions of those counties in play
for 0.5"-1.0"+/hr snowfall rates for a time with some locally
significant travel impacts. Other locations across eastern portions
of our lakeshore counties will see considerably less snow with only
minor inconveniences to travel.

There is a question with regard to how quickly the band moves inland
and dissipates. The Nam3km does this several hours quicker than the
HRRR/RAP13, which prefers little movement in the current band
placement, perhaps an initial jog to the east and then a migration
back toward the coast before weakening. Lift within the DGZ, 1000mb-
700mb RH, and 925mb-850mb omegas suggest we need to stretch out the
Warning a bit further in time than previously thought as these model
fields are not declining until mid afternoon or so. In addition, it
is looking less likely that the band will cause Warning level
impacts to Kalamazoo County so we are downgrading to an Advisory, as
there should still be impacts to travel primarily for the western
half of the county especially between 09z-18z.

- Very Light Wintry Mix Possible Saturday Night

Model guidance indicates less than a tenth of an inch of mixed
precipitation is possible Saturday night as a robust 50kt LLJ
advects warmer air and some Gulf moisture up into Lower Michigan.
This looks to occur at night with temperatures in the upper 20s to
low 30s. Although this looks like a minor event, there could be some
slippery roads developing if the precip stays liquid until contact
with colder road surfaces, turning it to ice.

- Lake Effect Snow Showers for Sunday Night through Monday

Another blast of Arctic air arrives Sunday into Monday with a WNW to
NW lake effect setup taking place. With the DGZ dropping toward the
ground the flake size will not be optimal, thus accumulation rates
will likely not be very impressive, but often in these setups the
visibility reductions can actually be worse than events that produce
larger dendrites. In addition, 850mb winds look to be 30-35 kts
which should get some snow shower activity inland a bit. Surface
winds look to be 15-25 kts so there could be some travel impacts
from this event even though it may not be a significant snow
producer.

- Milder Mid Week to Late Week Period

After highs in the teens early this upcoming week, we look to
quickly rebound into the 30s as rising mid level heights and low
level warm advection takes shape over the Great Lakes. Toward the
end of next week there is some support by ECE ensemble members of
additional precipitation that could impact our region, potentially
snow. Upper level pattern evolution a week out, however, is highly
variable and subject to change until details become clearer.

&&

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 112 AM EST Fri Jan 7 2022

The winds have calmed along the lakeshore, but the snow will
continue which will keep vsbys IFR and lower. The calming winds
have allowed low cigs to form, especially at MKG.
 As winds calm inland overnight, there is a chance for IFR to
VLIFR cigs and vsbys for a period between 11Z and 15Z at KLAN.

Otherwise, improving conditions at BIV, KGRR, KAZO, KBTL and KJXN.
 The northwest flow will keep IFR cigs and vsbys possible from
snow bands at AZO and briefly at GRR. The snow will continue
into Friday during the day at BIV and AZO.

 Conditions will slowly improve Friday afternoon into Friday
evening as snow tapers off and skies begin to clear.

&&

.MARINE...
Issued at 330 AM EST Fri Jan 7 2022

Winds and waves will continue to be hazardous to small craft until
this afternoon. After a break tonight, hazardous conditions once
again develop with strong southerly flow increasing over the lake
on Saturday. Gales are possible for our northern zones. Very large
wave action looks to develop north of Muskegon on Saturday. Winds
and waves still look hazardous right into Monday.

334 PM EST Thu Jan 6 2022

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

.DAY ONE...Tonight

Lake effect snow will primarily impact travel near and west of US
131 today into Friday morning.  Snowfall amounts, possibly over a
foot may occur overnight for locations near Big and Little Sable
point and near US-31, from near South Haven south. This will make
for very challenging travel conditions.

This evening a heavy lake effect snow band, associated with surface
cold front is bringing heavy snowfall with rates up to an inch an
hour from near Holland to Grand Rapids. This snow band will move
toward I-94 after dark and bring heavy snow there for several hours.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Another round of lake effect snow showers is possible Sunday night
into Monday, but accumulations currently do not look as
significant as the ongoing event. Still, some impacts to the
Monday morning and Monday evening commute are possible.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
