Update on today’s snow event

12:49 PM Tuesday, December 28, 2021

Snowfall reports coming in out of northwest Minnesota shows anywhere from 2 to 6 inches of snow this morning with snow still coming down in that part of the state.

I haven’t seen any snowfall reports yet out of the Northland, but it has been snowing (heavily at times) from International Falls south to Brainerd this morning with some lighter snows farther east.

Snow will slowly develop in the Twin Ports through the afternoon.

Snow is falling over a large portion of the Northland early this afternoon with some pockets of moderate to heavy snow (green colors on the map) focused over parts of north-central Minnesota.

There is still some dry air lingering over the Twin Ports early this afternoon, but the atmosphere is slowly saturating, and snow should start to fall shortly in Duluth (by 2 PM today).

Snow will continue in the Northland through early this evening before ending from SW-NE from mid to late evening through the early morning hours of Wednesday. Snow will linger longest in the Arrowhead and Borderland areas.

For Duluth — Snow begins ~1 PM to 2 PM today, snow ends around Midnight tonight. Total snowfall accumulations of 2 to 4 inches are possible by late tonight.

Here’s my updated snowfall forecast through early Wednesday morning.

A few changes here and there but nothing too drastic.

An area of low pressure was analyzed over northeastern Kansas at Noon today, this low will head NE while remaining well south of the Northland through tonight, but an inverted trough extending north of the low into western Minnesota will work its way to the east and that trough will be the culprit behind today and tonight’s snow event which will impact the Northland.

Strong vertical lift (orange and red colors) is occurring out ahead of an approaching trough and this has led to areas of moderate to heavy snow in parts of western, central and northern Minnesota this morning.

Our impressive temperature contrast continues today.
