Lake effect snow showers will diminish early Tuesday morning as high pressure builds into the forecast area. The cloud deck will retreat quickly and we end up with a mix of sun and clouds through a balance of the day. However, tranquil weather will be short-lived as high clouds and breezy southerly winds stream in later this afternoon ahead of the next weather disturbance.
Gusty winds and scattered snow associated with that system will sweep across the Upper Peninsula overnight, into Christmas morning. New snow accumulation will be kept to around two or three inches across much of the area. However, higher snowfall totals are expected along portions of the Keweenaw Peninsula and across our eastern counties through Christmas Day. The heaviest expected snowfall combined with gusty winds and blowing snow has triggered a Winter Storm Watch for Schoolcraft, Luce, Mackinac and Chippewa Counties. Those watches will become effective at 1 a.m. eastern on Christmas morning, falling away into the afternoon and evening on Christmas Day.
5-8?? of new snow could be seen along the Keweenaw Peninsula and through parts of eastern Upper Michigan. Winds perhaps gusting above 30 MPH off of Lake Michigan will enhance snowfall amounts from roughly Manistique to Newberry and in far eastern Upper Michigan. As much as a foot of new fluffy snow is possible for those areas through Christmas Day. Strong winds will also bring blowing snow and reduced visibility, creating potentially hazardous travel conditions during this time.
Although temperatures will sink into single digits over the next couple of nights, relatively mild daytime temperatures are expected to end the short work week. I say mild because the next low pressure disturbance will bring colder air and lake effect snow Sunday through at least the first half of next week.
