Area Forecast Discussion
National Weather Service Gaylord MI
1132 PM EST Tue Dec 10 2024

.KEY MESSAGES...

- Lake effect machine fires up later tonight through Thursday.
  Significant snow accumulations expected in some areas...
  particularly for locales across the snowbelts of northwest
  lower Michigan, with lesser (but still considerable) amounts
  across the snowbelts of eastern upper Michigan.

-Temperatures return to climatological averages this weekend.
 Mixed precip likely moves across the area Sunday.

&&

.UPDATE...
Issued at 1124 PM EST Tue Dec 10 2024

Confidence continues to increase in significant lake effect snow
across parts of northern Michigan Wednesday and Thursday. Main focus
will begin near and south of Grand Traverse Bay tonight into
Wednesday, and then refocus across the typical lake effect
snowbelts of northwest lower Michigan as winds shift from north
to west-northwest by the evening. Forecast soundings display an
impressive environment supportive of snowfall rates in excess
of 1 inch per hour at times Wednesday night into Thursday. Due
to this, the previous Winter Storm Watch has been upgraded to a
Winter Storm Warning for Crawford, Otsego, Cheboygan, and Emmet
counties, and a Winter Weather Advisory for Oscoda,
Montmorency, and Presque Isle counties.

&&

.SHORT TERM /THROUGH WEDNESDAY/...
Issued at 300 PM EST Tue Dec 10 2024

APX radar shows mainly light snow showers inland and mixed rain
and snow showers near the lake shores at the moment. Mainly
light activity is expected to continue into this evening
(eventually in the form of snow showers everywhere) as colder
air steadily advects into the region increasing over lake
instability. The problem is that the steering low level flow is
rather light and chaotic so lake generated snow showers will
have a hard time focusing in any one place. Hi-resolution
guidance tries to generate meso-vortices near the lake shores
overnight but the locations of these possible features vary
based upon each individual model. The most consistent signal is
from the Grand Traverse Bay region southwest to Manistee...so
will upgrade from the winter storm watch to a warning in that
area. Could see a few inches of snow by morning. The flow slowly
increases Wednesday, first across the northern Lake Michigan
shoreline so will upgrade the warning from Charlevoix to
Kalkaska starting at 7 am. The remainder of the watch will be
pushed forward to Wednesday afternoon where the steadier snow is
expected to take longer to reach. Southeast zones will remain
headline free at this point but mainly lighter snow showers will
eventually reach there as well. Heavier snow showers are likely
Wednesday night into Thursday (see below).

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
Issued at 300 PM EST Tue Dec 10 2024

Pattern Synopsis/Forecast: Current midlevel longwave troughing
continues to draw southward from Hudson Bay into the Great Lakes
region bringing a cold Arctic air mass with it. Great Lakes water
temps still remain well above average for this time of the year
allowing for Accumulating lake effect snowfall to persist this
Thursday and likely continue lingering showers into Friday.

Midlevel heights begin to rise Friday afternoon as a shortwave ridge
from the Rockies causes the cold air to retreat back to Canada.
Temperatures at the surface will return to near normal for mid
December before an upstream shortwave continues active weather this
weekend into early next week. 850 mb and surface temperatures
hovering around freezing will re-introduce mixed precipitation into
the northwoods around the Sunday/Monday timeframe.

Primary forecast concerns/key messages:

-Strong chances for significant accumulating snow for areas along
the snowbelts. Chilly Arctic airmass pulls cold temperatures into
the Great lakes region this Thursday and Friday: A large amount of
focus remains for the ongoing accumulating LES ongoing at the start
of the long term period. Heaviest snowfall rates of 1-3" per hour
will be in the overnight hours of Wednesday into Thursday. Biggest
difference between the set up Wednesday night will be the increasing
gust winds carrying snow inland, impacting the more typical
northwesterly flow areas rather than closer to the Lake Michigan
shoreline during the day Wednesday. Brisk winds combined with strong
low level instability will bring some pretty high snowfall amounts
to parts of Kalkaska, Crawford, Otsego, Charlevoix and Antrim
Counties as inversion heights shoot to +15,000 feet in the overnight
hours. Probabilistic guidance continues to push a general 6-12+
across these areas, but if latest hi-rez guidance comes to fruition,
multi lake banding could deliver locally higher snowfall totals of
up to 2 feet of snow, as long as snowflakes will be able to
efficiently extract from the DGZ and not remain a column structure.

With key focus being on the snowfall... Cold temperature will impact
the entirety of the CWA Wednesday night through Friday with daytime
highs in the teens to low 20s and overnight lows plummeting to the
single digits. Thursday will bear the brunt as 25-30+mph gusts will
drop apparent temperatures to near zero.

-Temperatures return to climatological normal this weekend. Mixed
precip moves across the area this Sunday: Strong Pacific jet flow of
up to 150kts begins to overpower northerly troughing and returns
more mild temperatures this weekend. Troughing develops surface low
pressure lee of the Rockies and continues snowfall through the end
of the week, but warm air advection will result in some mixed
precipitation across the CWA. Ensembles continue to keep 850 mb and
surface temperatures around freezing. Still a little too early to
pinpoint exact accumulations for possible icing amounts, but will
likely be a similar setup to last weekend with local elevations and
geographic locations playing a big factor on impacts.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 1132 PM EST Tue Dec 10 2024

MVFR CIGs are anticipated across a majority of the TAF sites through
the issuance period. The exception will be the possibility for
temporary IFR CIGs with heavier lake effect snow showers, primarily
at TVC. IFR VSBYs are also anticipated at times with lake effect
snow showers moving over TAF sites. Otherwise, mainly light north
winds will turn to west winds by Wednesday afternoon and look to
strengthen to around 5-10 kts with gusts to around 15 kts for
some areas.
