Winter Storm Update

12:05 PM Sunday, December 5, 2021

Snow continues to fall in parts of the Northland early this afternoon, with the heaviest snow generally along and north of the Highway 2 corridor in northeast Minnesota, and also impacting far northern Wisconsin (Bayfield Peninsula area).

Snow is expected to continue in much of the Northland through this afternoon and into this evening with the heaviest snow extending from north-central to northeast Minnesota, including along the North Shore of Lake Superior.

Gusty winds are also occurring in parts of the Northland which is leading to areas of blowing snow today.

16z/10 AM HRRR model run ending 4 AM Monday.

An area of low pressure was located near Fargo, North Dakota at 11 AM today, this low will continue to move to the ESE reaching eastern Minnesota by this evening.

Strong forcing has been occurring ENE of the surface low this morning which has resulted in an area of heavy snow generally along and north of the Highway 2 corridor in northeast Minnesota, and also impacting the Bayfield Peninsula in northwest Wisconsin.

The entire Northland continues to be under some sort of winter weather headline through early Monday morning.

Blizzard Warning (red)
Winter Storm Warning (pink)
Winter Weather Advisory (purple)

Our area remains in a strong warm air advection pattern late this morning with low pressure to our SW, but this warm air advection will be replaced by strong cold air advection later tonight once the low exits our area to the east.

Mid and upper-level trough continues to dig ESE out of eastern North Dakota and northwest Minnesota late this morning, this deepening trough is contributing to strong lift in the atmosphere in parts of the Northland today.

A deep dendritic growth zone (black outlined area) is in place across parts of north-central and northeast Minnesota and far northern Wisconsin this morning, and this is causing large snowflakes to develop and fall from the sky. Larger snowflakes accumulate much more efficiently than smaller snowflakes.

Here’s my storm total snowfall accumulation forecast, not additional snow amounts.

Far southern portions of the area (black outlined area) have already seen most of its snow from this system with only some additional light snow expected through this evening.
