An active clipper pattern returns but no major winter storms expected at least through much of next week; More shots of arctic air likely into next week

3:57 PM Thursday, January 20, 2022

At least three clipper systems through early next week – See timing below.

1: Late Friday afternoon-early Saturday morning
2: Saturday evening
3: Sunday evening-Monday morning

The greatest chances for some accumulating snow in the Northland will be with the system late Friday afternoon-early Saturday morning, and with the one Sunday evening-Monday morning. The system for Saturday evening takes a more southerly route and may miss the majority of the Northland the way it looks now.

TIMING FRIDAY’S SNOW

Friday morning looks dry in northeast Minnesota and northwest Wisconsin.

Snow is forecast to spread NW-SE across the area Friday afternoon-early Friday evening, reaching western portions of the area between 1 PM-4 PM Friday, and reaching northwest Wisconsin mainly after 6 PM Friday.

Snow diminishes from W-E later Friday evening into early Saturday morning.

For Duluth — Snow begins around 4 PM-6 PM Friday and tapers off around 11 PM-1 AM Friday night/Saturday morning. Total snowfall accumulations up to 2 inches.

18z NAM 3km model simulated radar forecast valid Noon Friday to Noon Saturday (snow in blue colors)

Here’s my snowfall forecast for Friday’s event — Looking like a general 1-to-2-inch snowfall for much of the Northland based on forecast precipitation totals and snowfall ratios per model guidance. This should be a fluffy snow with ratios possibly >17:1.
