Area Forecast Discussion
National Weather Service Gaylord MI
221 AM EST Sun Dec 19 2021

.NEAR TERM...(Today through Tonight)
Issued at 219 AM EST Sun Dec 19 2021

High Impact Weather Potential: Gales on some nearshore waters
tonight.

Pattern Synopsis/Forecast:

Fast paced, marginally amplified central NOAM upper/mid level
pattern continues at this early hour. Shortwave trough responsible
for yesterday's light snow event exiting rapidly stage right as
broad upper level ridge axis builds into the northern Plains and
Upper Mississippi Valley region. Elongated surface high pressure
running just ahead of its upper level parent (as it should),
stretching from central Ontario southwest through the western Great
Lakes. Still some remnant very light lake snows targeting our
traditional lake belt locales early this morning...although trend
has definitely been toward less organization as dry air and deep
layer subsidence take their collective toll. Water vapor imagery,
overlaid with hi-res guidance initiation, shows our next feature of
interest as shortwave trough digging steadily east through the
southern Canadian Rockies. Fast paced environment mentioned earlier
shows no sign of abating, with both surface and upper level ridge
axes crossing our area today into this evening, with that southern
Canada wave and attendant cold front approaching the area by sunrise
Monday.

Primary Forecast Concerns/Challenges:

Temperature/cloud trends and addressing some light snow
potential...especially late tonight.

Details:

Expect winds to turn southwest and increase in speed today as
surface ridge axis crest the area this afternoon. Although the low
level environment remains more than cold enough to continue to
entice a lake response off northern Lake Michigan, dearth of
synoptic moisture contribution and an increasingly shallow
convective layer sure argues otherwise. Still, gotta believe plenty
of shallow clouds will continue to target the favored southwest flow
areas, with even a few flurries/very light snow showers...with any
accumulations remaining trivial. Otherwise, expect at least some
partial sun elsewhere, with parts of northeast lower Michigan likely
experiencing a good deal of sunshine through the day. Doesn't look
like temperature respond too much from those southwest winds, with
highs mostly in the upper 20s to lower 30s.

Southwest winds continue to increase tonight, becoming quite gusty
at times, as that upstream wave and attendant cold front approach
the western Great Lakes. Continued modification of the low level
environment should quell any ongoing light lake effect. Arrival of
deeper moisture/forcing looks to bring a bit of light snow toward
morning across parts of eastern upper Michigan, with only minimal
accumulations. Temperatures go much of nowhere, or even rise a bit
overnight, as those southwest winds increase. Of course, those gusty
winds will make it feel several degrees colder yet.

&&

.SHORT TERM...(Monday through Tuesday)
Issued at 219 AM EST Sun Dec 19 2021

...A few rounds of snow heading through early week...

High Impact Weather Potential...Minimal. Couple rounds of mainly
light accumulations. Best accumulations look to be Tuesday afternoon
and evening.

Pattern/Synopsis...An elongated positively-tilted trough through the
center of the CONUS will continue shifting east through the rest of
the weekend...exiting out to the Atlantic by Monday morning.
Meanwhile the northern stream jet ripples across the northern tier
of the country into the Great Lakes.The strongest wave moving by to
our north Sunday night into Monday induces a surface low that treks
straight across southern Canada through Sunday, closing in on James
Bay by Monday morning. Its associated cold front swings through
Michigan Monday afternoon and evening, bringing light snow. The next
clipper passes through Tuesday evening, bringing additional snow.

Forecast/Details...Heading into Monday we remain in gusty southerly
flow just ahead of the cold front with overcast skies per forecast
soundings. We get breifly into the warm sector in the morning, and
what the front lacks in moisture may be able to be compensated by
dynamic forcing from the wave...to help spread at least a quick shot
of snow across most of the area. Snow chances look to be ongoing in
Ern Upper in the morning thanks to the proximity of the front and
deepest moisture. Guidance keeps trying to spread reflectivity south
through at least a portion of Nrn Lower through the early
afternoon...We dry out and cool behind the front...with lake effect
ramping up for Ern Upper in the afternoon as we saturate up into the
DGZ. With continued CAA we'll see deltaT's climbing to 20C with
inversion heights stuck at 5 kft through the night. This lake effect
continues through the night, especially for Ern Upper. Overall
believe accumulations remain light through the day, with a couple
inches possible in portions of Ern Upper that get stuck under any
persistent banding.

Briefly quiet for the beginning of Tuesday with mid-level ridging
and surface high pressure moving through. But this quickly changes
as the next wave moves toward the upper Great Lakes...with its
associated surface low moving from the Dakotas early in the day to
the western U.P. by Tuesday evening. Great dynamic lift out ahead of
the digging wave will help intensify this sfc low as it moves into
southeast Ontario overnight. A corridor of high moisture (925-700mb
RH 90-100%) moves through during the afternoon and evening, mainly
along and north of M-72...helping support a quick burst of
potentially heavy snow through Tuesday afternoon and into the
evening. We'll have enhanced omega pegged squarely within a deep
DGZ, and snow may be heavy enough to quickly overcome any shallow
sfc-based dry layer. We start to loose saturation Tuesday night, but
with CAA/cyclonic flow behind the system lake effect snow showers
should still hang on through the night.

&&

.LONG TERM...(Tuesday night through Saturday)
Issued at 219 AM EST Sun Dec 19 2021

High Impact Weather Potential...Moderate. Monitoring holiday weekend
system

Pattern Synopsis/Forecast...Late week things become more uncertain
with discrepancies in guidance. A cut-off low off the Pac NW coast
will send surges of energy into the northern jet which rides across
the northern tier of the CONUS, each bringing their own precip
chances to the region late week. As of now there's potential for a
strong surface low to move into the region on Christmas Eve and
Christmas Day, potentially bringing messy rain and wintry mix, as
well as gusty winds...but there's still plenty of time for things to
change and for details to become clearer over the coming days. For
temperatures, the general consensus suggests ridging moving over the
region late week, with afternoon highs warming to near 30 north of
the bridge and mid to possibly upper 30's south.

&&

.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 1111 PM EST Sat Dec 18 2021

The dry air is working into N Lower faster than originally
thought, based on the radar returns diminishing quickly into
flurries. There will still be some issues with the CIGs downstream
of Lake Michigan being MVFR category, but the VSBYs look to now be
VFR through the night and into the next day. The next system that
is expected on Monday, will bring in more clouds Sunday evening,
and there is a possibility that the SW winds could produce some
snow showers near MBL and PLN (That flow doesn't usually get into
TVC).

&&

.MARINE...
Issued at 219 AM EST Sun Dec 19 2021

Southwest winds will be on the increase, reaching maturity
tonight/early Monday morning, as area become increasingly
sandwiched between departing surface high and approaching cold
front. Rather aggressive low level jet expected to develop (40+
knots at just a few thousand feet of the surface) by later tonight,
with the strongest core of winds running right up the spine of Lake
Michigan. Given a still somewhat unstable near surface environment,
would expect a good portion of this wind to mix to the surface. Gale
warning already hoisted across northern Lake Michigan tonight, which
may need to be extended up through the Straits and Whitefish Bay.
Solid small craft advisory conditions expected elsewhere. Winds
subside a bit Monday into Monday night as they swing around to
northwest (although widespread small craft advisory conditions look
to continue).
