Heavy snow Sunday afternoon into early Monday; followed by the coldest temps in years

Periods of light snow are expected across the southern half of Minnesota this Saturday morning into early afternoon.

Our main snow event of the weekend begins on Sunday.

The big picture

Snow will move into western Minnesota Sunday morning, then spread across eastern Minnesota and western Wisconsin during the afternoon hours.  Snow continues Sunday night into Monday.

The National Oceanic and Atmospheric Administration's North American Mesoscale forecast model shows the potential snow pattern Sunday morning through Monday afternoon:

The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of snow.

Heavy snow for many areas

Our season snowfall total is currently running 19.5 inches below normal in the Twin Cities metro area.

That'll change late Sunday afternoon into Monday, as we see our first heavy snowfall of the season in the metro area.

Here are snowfall projections for the storm:

Much of the metro area should see 6 to 9 inches of snow by the time it tapers off on Monday.

A winter storm watch includes the Twin Cities metro area from 3 p.m. Sunday to 3 p.m. Monday:

...HEAVY SNOW AND BLOWING SNOW SUNDAY THROUGH MONDAY...

.A potent clipper system is still on track to shift southeast from

the Dakotas into Iowa then to Michigan Sunday through Monday. This

Minnesota into western Wisconsin Sunday afternoon through Monday

morning. The greatest snow accumulations look to occur from west

central Minnesota through the Twin Cities metro to around the Eau

Claire area, with lesser amounts towards northern Minnesota,

southwestern Minnesota and northwestern Wisconsin.

Therefore, Winter Storm Warnings have been issued for all of

central and southern Minnesota through western Wisconsin, with the

exception of a small portion of southwestern Minnesota south of

the Minnesota River. In these areas, a Winter Weather Advisory has

been issued.

Snowfall amounts in the warning area can be expected to range from

6 to 9 inches. Snowfall amounts in the advisory area can be

expected to range from 3 to 6 inches.

This system is expected to cause significant travel impacts,

especially Sunday night through the Monday morning commute.
