Area Forecast Discussion
National Weather Service Gaylord MI
329 AM EST Thu Mar 9 2017

.NEAR TERM...(Today)
Issued at 329 AM EST Thu Mar 9 2017

...Wintry temps to return tonight...

High impact weather potential...turning much colder tonight.

Multiple low pressure system are spinning away over northeast
Canada. The pressure gradient is slowly becoming a bit more lax,
which is welcome after a couple very windy days. A secondary cold
front lurks just north of Superior, and will cross the region
late today and early tonight. This will usher in a mid-winter
airmass as the night proceeds.

Today...shortwave energy is digging into the northern plains,
lighting off an f-gen band of precip that stretches across SD,
the MN/IA border, and southern WI. This will cross southern lower
MI today, bringing some clouds to southern sections, but precip
will stay to our south. Wnw-flow lake effect continues in our
forecast area, more prevalent and substantial coming off of
Superior than Lake MI. In general, a decreasing trend in
coverage/intensity is noted since midnight. Superior is more
active thanks to colder air/more instability, and a longer fetch.
We will be weakly warm advecting for much of the day, which will
take a further bite out of lake effect in both peninsulas. Will
likely need to start the day with sct to perhaps nmrs shsn in the
snowbelts, with the highest pops in eastern upper. Even those will
dwindle with time today. Hard to see daytime accums being more
than an inch or so in nw Chip Co, and less than that elsewhere.
Might be an opportunity for a slight uptick again as we head
toward dusk, as colder air starts to work back into northern
sections, along with an increase in moisture at the 700-600mb
level. But that mostly comes into play tonight (after 7pm).

Max temps in the mid 20s Chip Co to upper 30s Arenac Co. Pressure
gradient will be tighter in northern areas than further south, and
places north of M-32 will remain on the brisk/blustery side. Winds
will become lighter further south.

Tonight...a deep-winter airmass invades tonight as the secondary
cold front exits. 850mb temps will tumble to within a few degrees of
-20C by morning, coldest north and warmest se. -30C air will graze
the northeast shore of Superior. One modestly enhanced area of mid-
level moisture will pivot across the region in the evening,
associated with a shortwave helping to drive the cold front across.
This moisture precedes the arrival of best instability, and
regardless Bufr soundings show a persistent dry layer between active
lake convection and any mid-level moisture (which is above 700mb).
So don't think lake effect will get a lot of synoptic assistance.
But the sheer amount of instability, combined with inversion heights
rising slightly to 800mb, will kick off an increased amount of lake
effect snow showers. However, the intensity thereof will be hindered
by the dryness of the inbound airmass (surface dew points north of
Superior will be well below zero). Sct to nmrs snow showers will
return as the night proceeds, with 1-2 inch accums in western Chip,
with less elsewhere. Blowing snow will also return, especially
overnight, as the pressure gradient once again tightens and nw winds
become gustier.

Min temps tonight in the single digits to lower teens in most
places, a little warmer in the far se. Sub-zero wind chills will be
common by morning, with -10 to -15f seen in eastern upper.

&&

.SHORT TERM...(Tonight through Saturday)
Issued at 329 AM EST Thu Mar 9 2017

...Colder with lake effect snow showers...

High Impact Weather Potential...Minimal. Some accumulating lake
effect snow, but amounts don't look significant. Reduced
visibilities from blowing snow likely in some areas on Friday.

Pattern Synopsis/Forecast...A strong Canadian high pressure ridge
will build into the Upper Midwest Friday into Saturday. This will
send a pool of Arctic air southward into the region with 850mb
temperatures dropping to around -25C on Friday. This cooling of
temperatures aloft will generate very steep low level lapse rates
(roughly 0 to 1.5km) conducive for widespread lake effect snow
showers across northern Michigan. Winds will be brisk (especially
Friday with gusts to around 35 mph), staying locked in a
northwesterly flow pattern through Saturday with only very subtle
wobbles from time to time. This will result in a long fetch
length/duration for eastern Upper and a strong onshore convergence
axis stretching from Alger County into Whitefish Bay. The NW winds
will also lead to decent onshore convergence along northeast Lake
Michigan as well as orographic lift across northwest Lower (forecast
soundings for PLN and APX show modest low level omega). Inversion
heights will be respectable, just shy of 2km. Really the only
limiting factor will be moisture, as PWATs drop to a near bone-dry
0.07" or less on Friday. However, with all the other ingredients
looking adequate or better, am not expecting the paltry atmospheric
moisture to limit LES potential - just potential accumulations. With
low QPF amounts and a shallow (0.5km) surface-based DGZ, looks like
only small accumulations over an extended period of time. Blowing
snow will be a concern on Friday especially near the lakeshores.

Despite a very small increase in low level moisture on Saturday,
inversion heights will drop to about 1km as the surface ridge builds
in further. This will result in increasing subsidence aloft as well
as lighter winds than Friday, so expecting comparatively less LES
activity, especially over northern Lower.

Primary Forecast Concerns...Lake effect snow and temperatures will
be the main forecast concerns given the anomalously cold airmass.
Not expecting any significant snowfall amounts given the limited
moisture, but Friday looks to have a greater potential for some
light accumulation over northern Lower. Eastern Upper will likely
see some accumulation both Friday and Saturday. Current forecast
total snowfall Friday through Saturday night runs up to 1-2 inches
mainly along/north of M-32, with around 2-4 inches across most of
eastern Upper. Latest GEFS run continues to show 850mb temps running
2 to 3 sigma below the mean Friday into Saturday with GEFS and SREF
temperature plumes showing little spread Friday through Saturday. So
high confidence in a very cold end to the week, but less confidence
in exactly how cold will it get Friday night given northern Michigan
won't decouple overnight. Went a little warmer than most MOS
guidance across northern Lower, but do expect eastern Upper to be
the cold spot with some subzero temperatures not out of the question.

&&

.LONG TERM...(Saturday night through Wednesday)
Issued at 329 AM EST Thu Mar 9 2017

High Impact Weather Potential...Minimal.

Unseasonably cold air will remain over the Upper Great Lakes through
the remainder of the weekend, gradually retreating into eastern
Canada Monday through Wednesday. Temperatures will moderate a little
each day but will remain below freezing across northern Michigan
until milder air starts to creep into our southern counties on
Wednesday. The cold air will also support a continued chance for
lake effect snow showers at times through Monday. Models remain
split on the track of a clipper-type system for Monday into Tuesday
with the GFS/CMC favoring a more southern track and the ECMWF
bringing more precipitation into northern Michigan. Low confidence
this far out as the track will certainly continue to change, but at
this time areas south of M-32 would stand the best chance at seeing
any snow (light amounts) from this system. High pressure then builds
in from the west for Tuesday and Wednesday, bringing mainly dry
conditions to the region.

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1145 PM EST Wed Mar 8 2017

...Gusty winds continue to slowly diminish overnight...

Winds will remain gusty at times through early Thursday morning
but are expected to slowly diminish toward morning. Winds will be
much more tame on Thursday into the first half of Thursday night,
with a few gusts pushing 15 to 20 knots. There could be an
isolated snow shower from time to time but overall not much
weather is expected through the taf period. Cigs/Vsbys should be
vfr, though a brief foray into MVFR can not be ruled out in a
heavier shower.

&&

.MARINE...
Issued at 329 AM EST Thu Mar 9 2017

Winds have been slowly diminishing early this morning, and that
trend will continue today. Another round of gusty nw winds (not
as strong as the last couple of days) arrives late tonight, behind
a secondary cold front that will bring much colder air to the
region. After a bit of a lull, potential for gales returns very
late tonight and especially Friday.
