Our massive winter storm is still swirling around the Upper Midwest. The precipitation plume with this system wraps around the low-pressure center from Denver through the Dakotas, northern Minnesota, and Wisconsin all the way south to the Gulf of Mexico Wednesday. The precipitation plume stretches about 2,500 miles!
Snowfall totals so far
Snow is piling up Wednesday along the North Shore. Intense snowfall plumes are dumping snowfall rates of 1 to as high as 3 inches per hour.
And check out this great little thunder snow burst from Duluth:
As of this post over a foot of snow has already fallen 7 miles northwest of Two Harbors.
Snowfall totals are climbing fast along the North Shore. Here are some more select snowfall totals as of Wednesday afternoon, in inches:
Near Two Harbors, 12.5

St. Cloud, 5-6

Next wave overnight
The low-pressure system will slide east into Wisconsin overnight then still Thursday. Another moisture plume will wrap around the system, expanding snowfall coverage across most of Minnesota overnight into Thursday.
The National Oceanic and Atmospheric Administration’s NAM 3 km model captures the spinning low and snow plumes wrapping around the system between 6 p.m. Wednesday and 6 a.m. Friday:
Significant snowfall totals still ahead
The stalling storm and long snowfall duration will produce hefty snowfall totals across most of Minnesota by Friday. The Twin Cities could easily pick up an additional 4 to 8 inches by Friday. A foot may fall across parts of northern Minnesota.
And the North Shore snowfall totals still have the capacity to produce additional feet of snow. I will not be surprised to see total snowfall over 3 feet along parts of the North Shore from this storm.
