In regards to the potential "Thanksgiving Storm", this looks like a Mid Atlantic storm (fast mover too). The real deal will be the much colder airmass by weeks end that could provide numerous snowshowers in S MI. LES will be rockin in some of the snowbelt areas. I think @westMJim and @tStacsh stand the best chance at seeing substantial snowfall next weekend in terms of LES. As @Tom noted previously in his post, heck, even my area can see some hvy snowshowers crossing across the state. That should be fun. Hopefully, when I get back from my Thanksgiving trip, I will find white gold otg.
..and so it begins (correctly too - with the UP getting white gold 1st, then coming south)

Primary Forecast Concerns:
Snow Accumulations Monday into Tuesday...Negatively tilted trough
axis swinging through the region Monday, accompanied by potentially
anomalous moisture (pwats approaching 0.75in...top end of climo for
this time of year here) and some weaker stability aloft...suggests
we could see a punchy little system (i.e., "over-productive"
clipper system). Greatest threat for snowfall accumulations will
be the eastern UP, where thermal profiles suggest it should
remain mostly/all snow...and where best forcing along and north
of the low/warm front should be focused. Current probabilistic
guidance hinting at a decent shot of 2-4 inches of snow over the
EUP through Monday night, with a sharp gradient toward the
Straits....though if the system ends up tracking a bit further
south than currently anticipated...this could draw the snow
potential a little further south than currently expected. Less
certainty in how much snow will accumulate across northern Lower
(though the interior higher terrain should have the best shot
at accumulations, as usual)...as it may not turn cold enough
till late Monday afternoon/evening behind the low pressure/cold
front associated with this system.
Expecting this to transition to additional WNW/W flow lake effect
Tuesday...which should also be decently punchy, noting potential
inversion heights around 6-7kft...perhaps even as high as 8-10kft?
Winds should be stronger with this, too, which could drag lake bands
further inland. Suspect this is when better snow potential for
northern Lower will occur...so if this were to verify as a snow
event, not impossible that we could see at least 2-4" Monday night
into Tuesday over NW Lower.
There is a bright side to the pimple on the 0z EURO parked over us: our vehicles will stay clean. Washed both our vehicles yesterday in anticipation of meteorological tedium. It was a month’s worth of road grime and brake dust that was washed off.
Another breezy but dry day today with temperatures within a couple of degrees above our normal high of around 50 degrees. We warm to above normal both tomorrow and Tuesday before the big pattern change to below normal temperatures sets in by Wednesday. Looking ahead below normal temperatures look like a good bet to close out the month and last through at least the first 10 days of December. We have a couple rain chances this week - the first one will be tomorrow night with the cold front and then again with the possible coastal storm on Thanksgiving Day.
