Northland Snowfall Totals from December 29-30, 2020; Gusty Winds possible along the North Shore tonight; mainly dry through this weekend

Last night’s snow event was an overachiever in some parts of the Northland, this was especially true near Lake Superior where widespread 5-6″+ snow totals were reported, including nearly a foot of snow near Cornucopia, and nearly 8″ of snow reported in the Two Harbors area. Totals in Duluth were right around 5 to 6 inches. For the record, I did mention in my blog post last evening the possibility for there to be isolated 5″ totals across the area, but I did not expect there to be so many locations that reported 5″ or more of snow last night, so yeah I’m a little surprised about that. All about the fluff factor, large snowflakes accumulate very efficiently.

December 29-30, 2020 snowfall total at the Duluth Airport was 5.3″ with 0.29″ of precipitation. Snow to liquid ratio was 18:1 in Duluth which was what the computer models were showing for this event, so that’s always nice to see. By the way, the snow to liquid ratio in Duluth was a whopping 32:1 for today (since Midnight) with 2.9″ of snow, melted down to 0.09″ of liquid precipitation, that’s an incredible ratio! A very fluffy snowfall.

The pattern ahead at least for northeast Minnesota and northwest Wisconsin looks pretty quiet thru this weekend, and possibly into next week as well, but there are a few systems to keep an eye on for next week, but so far there is no consistency on storm tracks per model data (shocking I know)

Note: A month that started out very dry in the Northland has turned quite snowy during the second half of December, but snowfall totals for the month continue to run slightly below normal at Duluth (-1.0″), and slightly above normal at International Falls (+0.8″)

It’s been an odd La Nina up to this point, with the pattern since November resembling an El Nino more than what a typical La Nina pattern would look like.

The next big storm will pass well south of the Northland as it tracks from northern Mexico to western Ohio through Saturday morning (orange line on map) while another strong low nearing the Pacific northwest this afternoon weakens as it heads east.
