A surface low pressure system is passing south of the U.P. moving northeast. It is still strengthening and is the main cause of the New Year's Day snow. Its strong pressure gradient is also the cause of our windy conditions.
Winter Storm Warnings are still in effect across much of Upper Michigan. Though there are no Blizzard Warnings issued at the time of writing this story, it is still a possibility for later tonight.
Already there are several inches on the ground across several counties. Houghton County has multiple reports of over 5" as of this morning and more than 7" in Silver City. A strong northwesterly wind is reducing visibility at times. Sustained winds are well over 20 mph, but gusts can easily exceed 30-40 mph.
Outside of the snow, today's highs are mild around 30, but wind chill is making the thermometer seem like a liar. Lows tonight on the other hand will be in the 10s.
The heaviest snow will likely be this evening when lake enhancement really begins to take effect. As it turns into Monday, snow will persist but become almost entirely lake effect and mainly impact the northern counties.
Monday's highs will be in the 10s with lows around 0, but strong winds will persist through Monday evening and make things feel even colder.
Total snow accumulations through Monday night could easily exceed 14" in the northwest with similar amounts east of Marquette County. Marquette County should see over 8" and lesser amounts further away from Lake Superior.
Drive slow and drive safe! There are bound to be many interesting picture opportunities with the snow. Be sure to share them with us on www.uppermichiganssource.com. Happy 2012!
