Area Forecast Discussion
National Weather Service Gaylord MI
628 AM EST Fri Dec 11 2020

.NEAR TERM...(Today through Tonight)
Issued at 336 AM EST Fri Dec 11 2020

Minimal. Rain and snow starting tonight.

Pattern synopsis and forecast:

Upper troughing and an area of low pressure was out in the central
and srn Plains early this morning, resulting in light rain and snow.
More showers extended south through OK/TX. Broad/minor ridging and
sfc high pressure were over the eastern states, with drier air
leading to much clearer skies. Here in nrn Michigan, a moisture-
starved cold front was crossing the region, and developing northerly
winds were feeding some colder air and low level clouds into nrn
Michigan. There was some fog out there as well, but nothing too
widespread or thick. An overall fairly quiet early morning.

The current cold front will drop south of us through daybreak, with
many areas stuck under dreary lows clouds, while higher level clouds
increase out ahead of the approaching low pressure. Clouds really
start to thicken up through tonight, as the upstream low pressure
strengthens, and spreads deeper moisture and forcing into nrn
Michigan. DPVA and theta-e advection/convergence increase, as does
left exit region upper level divergence on the nose of 110+kt jet
pushing into the Ohio valley. Maybe some FGEN sneaks into the srn
CWA. This will result in the development of rain and snow, lifting
from south to north, for primarily nrn lower Michigan (all snow in
the higher terrain) Only some light snowfall amounts are anticipated
in areas south of M-32, to around inch, and again, mainly in the
interior higher terrain. The action really starts getting cranked up
Saturday, with the strongest portion of this storm arriving then
(see more on that below).

High temperatures will mostly be in the upper half of the 30s and
some lower 40s. Lows tonight will largely range through the
20s.

&&

.SHORT TERM...(Saturday through Sunday)
Issued at 336 AM EST Fri Dec 11 2020

...Accumulating Snow Spreading North and West...

High impact weather: Accumulating snow; some blowing snow possible.

Primary forecast concerns/challenges: Track, precipitation type and
snowfall amounts.

11/00z nam and gfs guidance have both shifted the track farther
north, with a track squarely across the Thumb. In addition, the
surface low is deeper at about 995 mb. Qpf seems a bit overdone but
upwards of an inch or slightly more of liquid equivalent is
generated. This is expected to be overly aggressive but it does show
the potential for higher qpf amounts which may produce greater
snowfall totals. This track would also keep southeast zones as
mostly rain or a mix of rain and snow limiting snowfall
accumulations down that way. On the contrary, the ECMWF and the
Canadian are holding strong with their 10/12z run ideas of a
somewhat weaker surface low while keeping the track farther south
and east. All and all this forecast has high bust potential,
especially on the northwest and southeast peripheries with a large
variance in snowfall amounts possible. Will not deviate much from
WPC qpf guidance which ranges from an inch plus across southeast
zones to three-quarters of an inch central to little to nothing
northwest (across far western Mackinac and Chippewa counties).

As far as the details go, expect snow to continue to spread
northwest through mid morning Saturday likely becoming heavy at
times across interior areas while lighter snow falls across far
northwest lower while a mix of rain and snow falls across the far
southeast. Total snow accumulations could change but have upwards of
6 to 9 inches encompassing a swath extending from Alpena to Mio to
Cadillac northwest to Traverse City and Gaylord with 3 to 5 inches
across far northwest lower and southeast zones. Right now only 1 to
3 inches of snow accumulation is forecast across eastern upper
(perhaps with little to no accumulation across far western Chippewa
and Mackinac counties). These totals are derived from a blend of the
models and in most areas except for across southeast zones would be
underdone if the 11/00z NAM/GFS verify. Precipitation should begin
to tapper off from southwest to northeast late Saturday evening then
end overnight. Winds will be gusty into Saturday evening with some
blowing and drifting snow around but the wet character of the snow
should limit this from becoming widespread. Lingering clouds and
perhaps some flurries Sunday but overall much quieter condtions are
expected.

.LONG TERM...(Sunday night through Thursday)
Issued at 336 AM EST Fri Dec 11 2020

...Uneventful Weather for the Most Part...

High impact weather: None is expected.

Unfortunately extended models vary on the details of the expected
split flow aloft pattern next week. Mainly weak short wave energy in
combination with over lake instability may lead to a few chances for
snow showers through the week. Will have chance pops Sunday night
into Monday morning for now across northern and western zones. Kind
of random as to when other chance pop periods might be and later
shifts will hopefully be able to define the details a bit better.
Forecast temperatures will be slightly below climatological
averages.

.AVIATION...(For the 12Z TAFS through 12Z Saturday morning)
Issued at 628 AM EST Fri Dec 11 2020

A weak moisture-starved cold front will cross nrn Michigan through
daybreak, allowing cooler air and MVFR CIGS to fill into the region
via northerly and somewhat gusty winds. Clouds thicken through
tonight as a storm system sets it's sights on lower Michigan. Light
rain and snow will break out, mainly after midnight, with less than
a half inch for TVC/MBL/APN. CIGS may drop to IFR late in the TAF
period with more widespread precipitation arriving Saturday. Several
inches of snow will be possible Saturday into Saturday evening, with
snowfall rates likely exceeding an inch per hour, and snow ratios
around 10:1.

&&

.MARINE...
Issued at 336 AM EST Fri Dec 11 2020

A weak moisture-starved cold front will cross nrn Michigan through
daybreak, allowing cooler air to fill into the region via gusty
advisory level winds for many nearshore waters. Deepening low
pressure then approaches late tonight, with light rain breaking out
over Lakes Michigan and Huron. Rain and snow really pick up Saturday
and Saturday evening with portions of Lakes Michigan and Huron
seeing gale force NE winds, as this storm system tracks through
lower Michigan.
