The worst of which may stay south of MI like last time, tho GRR did mention lightning which qualifies as severe these days for Mich. I would think strong winds mixing down in any T-storm would be another threat. And yes, I'm really hopeful for the first measurable snow from the backside of the storm.

St Paul Storm Posted November 12, 2017 Report Share Posted November 12, 2017 12z GFS trending towards a stronger southern energy which is making sense, esp when a few days ago I saw the main jet energy tracking in this general fashion.Seems as though the models, especially the GFS, have been trying to strengthen the southern energy during the last few days but couldn’t quite get there. Today’s runs may be the start of some very nice trends. Still looks too warm for a huge snow anywhere in the forum, it we’ll see how this goes. The 12z GFS is almost a perfect track for a whopper snow here. Regardless looks like a deep storm is looking quite likely.

Stormgeek Posted November 12, 2017 Report Share Posted November 12, 2017 Although thermals look to cause issues with this storm this time around, it is nice to see a storm taking a pretty favorable track for the the area once it recycles and gets colder out.

At the moment, snow belts are likely to see the best chances for wintry precip. Nonetheless, it's going to be a large wind-driven system. I'd say most trees will be bare after this system which sets the stage for a wintry Thanksgiving week! Magnifies the rarity of Nov 15-16 '89 for SMI. Just really hard to get just the right combination for significant snow in SMI at this early time of autumn. 1 Quote Winter 2023-24 Snow Total = 52.8" (89% Normal Season) Largest Storm: 12" (1/12-13) Oct: 0.1 Nov: 2.9 Dec: 7.5 Jan: 31.7 Feb: 6.0 Mar: 4.1 Apr: 0.0 Avg = 59.2" (Harrison): 2023-24 = xx.x" Avg = 45.0" (KDTW): 2022-23 = 33.5" 2021-22 = 35.6" Avg = 49.7" (KRMY): 2020-21 = 36.2" 2019-20 = 48.0" 2018-19 = 56.1" 2017-18 = 68.3" 2016-17 = 52" 2015-16 = 57.4" 2014-15 = 55.3" 2013-14 = 100.6" (coldest & snowiest in the modern record!) 2012-13 = 47.2" 2011-12 = 43.7" Legit Blizzards (high winds and dbl digit snows): Feb 2011, Dec 2009, Jan 2005, Dec 2000, Jan 1999, Mar 1998, Nov 1989, Jan 1982, Jan 1978, Jan 1977, Apr 1975, Mar 1973, Jan 1967, Feb 1965, Jan 1918 Link to comment Share on other sites More sharing options...
Niko Posted November 13, 2017 Report Share Posted November 13, 2017 Looking forward at the strong winds w this system. All leaves will be gone by the weekend. 1 Quote Snowfall for Winter 2023 -24 for Metro Detroit Area Oct 2023: 0.2" AN Nov 2023: 2.2" AN Dec 2023: 0.5" BN Insane!

Perfect wind trajectory caused by the blocking -NAO is setting the stage for a 24hr+ LES scenario? Quote Link to comment Share on other sites More sharing options...

jaster220 Posted November 13, 2017 Author Report Share Posted November 13, 2017 Here's some key take-aways per NWS MQT's long-term disco this early morning. Basically, new season, but same ole story of models not getting a good read while key actors in the upcoming drama are over the data-sparse regions of the Pacific Ocean. From NWS MQT: Friday through early next week: The attention turns to the arrivalof the above mentioned strong, longwave trough during theFriday/Saturday time frame. The medium range models continue tostruggle with any sort of consistency from model to model, and runto run. This is to be expected given the transition to a highlyamplified upper-air pattern. The main upper-level energy associatedwith this system is currently digging south across the Gulf ofAlaska and is progged to sit and spin just off the coast of thePacific Northwest. Therefore, it could be a few days before ROABsadequately sample this system and the models converge on similarsolutions. Overall, the medium range models show this longwavetrough ejecting out across the Plains on Friday, and trackingeastward across the Great Lakes on Saturday. As this wave takes on anegative tilt, the focus for large-scale lift will increase andallow for two areas of low pressure to merge and deepen somewhere inthe vicinity of Lakes Michigan and Huron. Given the highly amplifiedupper-level pattern and the arrival of additional shortwave energydigging rapidly from Canada on the back side of the main trough onSaturday, tend to favor the slower ECMWF/Canadian solutions at thistime. The biggest uncertainty with this system will be systemprecipitation, both hydrometer type and amounts Friday throughSaturday. Confidence is higher that we will see strong and gustysoutherly winds ahead of the developing the system, and then verystrong and gusty northwest winds on the back side of the exitingsystem.Behind the system, strong cold air advection will spread across theregion and bring back lake effect snow showers late Saturday throughSunday across the northwest wind snow belts. With 850mb temperaturesprogged to drop to around -10 to -15C, strong lake-induced CAPEthrough the convective layer is expected to develop. This coupledwith forecast soundings showing ample lift and cloud depth throughthe DGZ will favor moderate to heavy lake effect snow. As mentionedabove, very strong and gusty winds are expected as well, especiallynear the shores of Lake Superior and across the Keweenaw. Therefore,expect blowing snow to become an issue. These strong and gustyonshore winds will also favor beach erosion near Lake Superior andthe potential for lakeshore flooding, mainly east of Marquette dueto large waves, late Saturday through Sunday.&& So, in a nutshell, stay tuned..
