-Tweaked my snowfall map just a bit, main change was to the 8-10" zone which I changed to 8-12" since snow will linger well into Tuesday in far northern Minnesota so event totals could certainly approach one foot up in that area.

-I still think Duluth and Superior will be in the 4-6" range since we already picked up about 1-2" with the round of snow early this morning, and with tonight's snow expected to bring about 2-4" of additional snow, that would put us into the 4-6" zone for event totals by Tuesday morning.

Weather Synopsis:

Snow has been falling today over northern Minnesota with about 1-3" of accumulation reported as of mid afternoon.  There's also been some enhanced bands of snow affecting a portion of the North Shore of Lake Superior, especially from near Silver Bay to Tofte.

Snow has also been occurring at times across east central Minnesota into parts of northwest Wisconsin but there's also some dry air over those areas, as well as near the head of Lake Superior which has led to little if any snow this afternoon especially around the Twin Ports area.

Highs today ranged from the upper teens in far northern Minnesota with mid 20s to low 30s in east central Minnesota and northwest Wisconsin.

*Frontal boundary stretching from south central Minnesota into central Wisconsin this afternoon will lift slowly north this evening before it gets shoved to the east late tonight and Tuesday thanks to a wave of low pressure which tracks northeast out of eastern South Dakota.

*Snow should continue tonight in northern Minnesota, in fact some moderate to heavy snow is possible as a potent upper level disturbance now over the northern Plains heads into the Northland tonight.  An easterly flow will also persist tonight along the North Shore of Lake Superior which will lead to some lake enhanced snowfall especially northeast of Duluth.

*There will also be some snow at times across east central Minnesota and northwest Wisconsin tonight but the better lift and moisture will remain farther NW from these areas.  Patchy freezing drizzle or drizzle could also occur tonight especially in portions of northwest Wisconsin where a light glaze of ice accumulation is possible.

*Turning colder on Tuesday as low pressure exits off to the east -- Winds will shift to the north/west with gusts around 20-30 mph developing.  Temperatures in the teens to lower 30s early in the day will fall into the single digits, teens and 20s by the afternoon.

*Snow will continue most of the day in northern Minnesota including the Borderland into extreme northeast Minnesota where a few more inches of accumulation are expected; Elsewhere lingering snow showers or flurries with little if any additional accumulation.  Areas of blowing snow over the entire Northland as the wind increases throughout the day.
