Area Forecast Discussion
National Weather Service Gaylord MI
336 AM EST Tue Nov 20 2018

.NEAR TERM...(Today through Tonight)
Issued at 335 AM EST Tue Nov 20 2018

High impact weather potential: More accumulating snow and
possible blowing snow for some areas.

Pattern synopsis and forecast:

Upper level troughing and associated forcing, sfc low and deeper
moisture are all exiting east early this morning. Much colder, but
quite dry air was working into the region via some gusty northerly
winds that have been developing. This is out ahead of sfc high
pressure which extended from the Plains to Ontario. This colder air
was producing some weak lake effect in north low level wind flow
regimes. Certainly nothing that is too impactful. Upstream across
central Canada, we already see the next shortwave and it's
associated sfc low which was working into Manitoba. This system was
taking a continental track and appears to not have a ton of moisture
with it based on some current Canadian obs.

Scattered weak lake effect snow showers in northerly flow regimes
will slowly translate northward through the day as 1000-850mb winds
gradually back to out of the WSW by later this afternoon. This is
due to the high pressure drifting across nrn Michigan and the
approach of the aforementioned Canadian shortwave. Snow accumulation
will be fairly minor due to the shifting winds and relative dryness
of the BL. That said, there will be some late day enhancement, as
the "deeper" moisture, WAA, DPVA and light snows from this system
arrive, starting the better seeder-feeder process. The better
snowfall is expected to be this evening though, and it's really a
quick-hitting kind of deal. However, the UVV's are quite impressive,
and there is a rather deep and near isothermal DGZ. Max lift however
is just under this dendritic growth zone based on many data sets.
Another similar looking scenario overnight, like the one ongoing
now. Much colder air filters into the region with H8 temps falling
to as -14C south to -20C north, and even with the large delta t's
and inversion heights to 5-6kft, the moisture in the BL is expected
to be relatively shallow, with and inverted V layer up to 3kft. 1000-
850mb flow will be veering all night too. Swinging from WSW to NW,
spreading out snow showers across a larger area.

Snowfall totals will be greatest across NW lower over to Drummond
Island, as the best snows occur while low level winds are out of the
WSW. Generally 1-2" totals there, but 2-4" north of M-32 and west of
I-75. An inch or less most other areas, down to none expected in NE
lower, in the far SE CWA toward Saginaw Bay.

Current gusty winds will be weakening through first half of the day
as high pressure arrives. The gradient tightens back up rather
quickly later this afternoon and through the night, as the sfc low
pressure tracks north of us and we stay in the tight gradient
through the night. Gusts of 20-25mph are possible by early evening,
and a mixed BL will keep similar numbers going through the night.
Areas along the NW lower and Whitefish Bay coasts are likely to feel
some 30-35mph gusts tonight. Blowing snow expected at times this
evening.

Highs today quite chilly, in the mid to upper 20s most areas. Lows
tonight ranging from 10-15F in eastern upper to 15-20F in most of
nrn lower outside of the NW flow regimes where clouds look to hold
readings in the lower half of the 20s.

&&

.SHORT TERM...(Wednesday through Thursday)
Issued at 335 AM EST Tue Nov 20 2018

...Cold but mostly quiet for Thanksgiving...

High Impact Weather Potential...Minimal aside from wind chills in the
single digits below zero Wednesday night.

Pattern Synopsis/Forecast...Troughing will deepen over eastern
Canada and the Northeast on Wednesday as a ~130 knot upper jet
streak digs into the Great Lakes region. At the surface, a departing
clipper system will be displaced by a strong Canadian surface high (+2
standard deviations above the mean) and a surge of colder air sliding
into the Upper Great Lakes for Thanksgiving. The high will slide off to
our east by Thursday afternoon, giving way to increasing warm air
advection and rising heights over northern Michigan as mid-level
ridging approaches.

Primary Forecast Concerns...Transient small lake effect snow chances
and Wednesday night low temperatures.

Tight thermal and pressure gradients over northern Michigan will lead
to strong cold air advection on Wednesday as we sit between the
departing clipper system and the encroaching strong Canadian high. H8
temperatures will quickly drop in the morning, ranging from -16C over
our southwestern counties to -21C over eastern Upper through evening.
This will, of course, promote favorable over-lake instability, but
moisture looks to become pretty limited as PWATs drop to ~0.1" or less
over eastern Upper and northeast Lower. Forecast soundings tell a
similar story, with low level moisture and inversion heights only
up to 5 to 6 kft and perhaps some dryness to overcome just off the
surface. Certainly not anticipating any significant activity given
limited moisture, but perhaps locally up to an inch Wednesday morning
within heaviest snow bands in NNW flow snowbelts. Shouldn't have
too much impact on holiday travel across northern Michigan. Activity
should mostly dissipate Wednesday evening as low level winds shift to
the NNE and subsidence increases aloft beneath the building high.
However, there may be a lingering band that pushes out over central
Lake Michigan and another over Lake Huron that likely won't pose any
impact to land.

Other big focus will be cold temperatures through Thanksgiving morning
as the brisk northerly winds on Wednesday usher in an unseasonably cold
airmass. Highs Wednesday will range from the teens across eastern Upper
to the 20s across northern Lower (near 20 degrees north of M-32).
925/850mb temperatures over northern Michigan are then progged to
drop to 2 standard deviations below the mean for this time of year by
evening. Skies are expected to at least partially clear across much of
the area Wednesday evening (especially along the I-75 corridor) before
mid-level clouds begin to increase somewhat during the second half of
the night. Winds will become light as the high slides overhead, but the
boundary layer likely won't become completely decoupled as per forecast
soundings. Still expect an efficient radiational cooling setup, which
will only be aided by current snowpack. Trended closer to MOS guidance
for Wednesday night's lows, with single digits across most of the area,
coldest across eastern Upper and interior northern Lower where lows are
expected to be closer to 0 degrees.

Partly sunny skies and generally quiet weather in store for
Thanksgiving day. Still on the cold side, but most areas at least a few
degrees warmer than Wednesday. Very small chance for perhaps some
flurries coming ashore north of Saginaw Bay during the afternoon as
veering winds become SSE.

.LONG TERM...(Thursday night through Monday)
Issued at 335 AM EST Tue Nov 20 2018

High Impact Weather Potential...Minimal.

High pressure pushes off to the east Thursday night with southerly
return flow drawing increasing moisture into the region through
Saturday morning. Mid level ridge axis will cross northern Michigan
Friday morning, leading to more moderate temperatures through the
weekend. A deep trough and associated cold front are then progged to
interact with the increasingly moist airmass to bring widespread
precipitation late Friday night into Saturday, mostly in the form of
snow Friday night before transitioning to rain Saturday morning.
Another system developing over the Plains will eject towards the Lower
Great Lakes later in the weekend, bringing more precipitation chances
to northern Michigan Sunday and Monday. Colder conditions make a return
on the backside of this system heading into the middle of next week.

.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 1152 PM EST Mon Nov 19 2018

Light lake effect snow at times.

Low pressure is moving east of Lake Huron. Lingering snow is
diminishing to spotty lake effect snow. Brief restrictions are
possible overnight, mainly at APN and TVC, but for the most part
VFR conditions are expected. A relative lull will settle in
Tuesday morning, before a clipper low approaches from the nw. This
will expand snow back into some areas late Tuesday, along with
potential MVFR conditions.

Northerly winds will be a touch brisk overnight. Winds will back
westerly Tuesday, initially lighter, becoming gusty again in the
afternoon and evening.

.MARINE...
Issued at 335 AM EST Tue Nov 20 2018

Winds will continue to wind down into daybreak with sub advisory
speeds expected for at least the first half of today as high
pressure crosses the region. Low pressure will be passing to the
north tonight and the pressure gradient tightens rather quickly
later today. We stay in that tight gradient through tonight and into
Wednesday. Advisory level winds start developing by early this
evening in the nearshores of nrn Lake Michigan, then spread
throughout all areas tonight and continue into Wednesday. Gale force
gusts are anticipated in coastal convergence areas from the Bridge
down through Presque Isle Light. Will continue to ride the gale
watch since this doesn't start until late tonight into Wednesday
morning. High pressure and lighter winds arrive Wednesday afternoon
into Wednesday night.
