No significant forecast changes. Here’s the latest Friday afternoon (18Z) NOAA NAM 3 km resolution model snowfall output. Southern Twin Cities could creep into the 6-plus-inch zone.

Snow will develop and move across much of Minnesota Saturday. The heaviest snow favors southern Minnesota from south of the Twin Cities to the Iowa border. This snow looks lighter and fluffier than our last system. It will create slick roads and difficult travel late Saturday and Saturday night. But it should be great snow for outdoor activities like sledding and skiing.

Let’s break down the details of the snowfall event.

A moderate strength low-pressure system tracks from Colorado to Kansas Saturday. Southerly flow ahead of the system will throw moisture aloft over the cold air dome sitting over Minnesota. That will generate a large snow shield over most of Minnesota Saturday and Saturday night.

NOAA’s NAM 3 km resolution model brings the bulk of the snow into Minnesota (and the Twin Cities) between 3 p.m. and midnight.

Snowfall will develop Saturday morning in southwest Minnesota. Most forecast models bring the leading edge of snow into the Twin Cities from southwest to northeast between about 2 and 4 p.m. 

Snowfall intensity will be light Saturday afternoon. Heavier, steadier snow is likely between 6 p.m. and midnight. Snowfall should end in the Twin Cities by 6 a.m. Sunday. It may linger through noon Sunday in southeast and northeast Minnesota.

Northwest Minnesota will likely see very little snow with this system. Overall I like the looks of this NAM model forecast snowfall solution.

Here are my snowfall projections for some specific areas. 

Here’s the Twin Cities National Weather Service snowfall projection for all of Minnesota. 

Here’s a closer look at central and southern Minnesota. 

This will be a drier snowfall than our last sloppy system. Models indicate snow to water ratios around 15:1. 

That means this snow should be easier to shovel, and better for outdoor winter sports like sledding and skiing. 

 Expect light snow to spread across Minnesota from southwest to northeast Saturday. Snowfall will be heaviest and steadiest Saturday evening and night. Travel conditions will be challenging from late Saturday afternoon through Saturday night.
