Discussion
The north side of the low will have much colder air, and the deformation zone for this event will be set up across the eastern UP and Lake Superior region. Totals greater than 1" of snow (some melting) will be confined north of M-55 to the Mackinac Bridge, while totals closer to the 3"+ mark are confined from St. Ignace up to Paradise and Sault Ste. Marie. Additionally, the Keweenaw Peninsula also may see the highest snowfall totals too.

You may have noticed that we added a new color for this event only. Because there is a gradual change from rain to snow... freezing rain, and even sleet is expected with this event. Sleet is like the shared sibling between snow and freezing rain. Sleet is snow that melted to rain really high up immediately after falling from the clouds, but spent enough time in the cold sector after melting to reform into tiny pellets. Freezing rain, however, forms when there isn't enough time for the rain to reform back into those tiny ice pellets due to that warm sector close to the ground, but because the ground itself IS a cold sector, it freezes on contact. Yes, sleet is slippery, but due to its properties, it's not quite as impactful. Still, because of the sleet's size, it accumulates in tenths of an inch similar to snow instead of hundredths like freezing rain. As a result, much of the white trace-1" corridor will likely fall as <1" of both snow and sleet. Again, not a huge amount, but worth mentioning. Timing for this snowfall will be similar to that of the ice. Anytime from 6 am EST Friday through the end of the day Friday is the expected duration.

Winter weather advisories are now in effect for the eastern UP regarding this snowfall. We will have traffic impact maps and timing maps coming later this afternoon after our Christmas morning activities. See you all back here soon!

WEATHER UPDATE via Midwest Weather >> I'm going up north to the U.P of Michigan on Friday to chase a potentially significant lake effect snow event from late Saturday night through Tuesday. Snowfall accumulations could be 1-2', if not higher, as high-res model guidance comes in when we get closer.
Another lake-effect snow event is increasingly likely behind an arctic front next Wednesday night through Friday, which we will need to keep an eye on. #miweather #keweenaw #westernup #marquette #munising #seney #newberry #soo #straitsarea #gaylord #cadillac #benzie #traversecity #petoskeyI'm going up north to the U.P of Michigan on Friday to chase a potentially significant lake effect snow event from late Saturday night through Tuesday.
