Season's first snow is spreading across upper Midwest, including Minneapolis/St. Paul; Strong winds, blowing snow observed in Dakotas, Minnesota

By Brian Donegan, Weather.com

The first accumulating snow of the season will blanket a swath of the northern Plains, upper Midwest and western Great Lakes into this weekend as a low-pressure system originating in the Canadian Rockies sweeps eastward across those regions.

Snow is currently falling in parts of eastern and southern Minnesota, as well as western Wisconsin and northern Iowa.

As of midday Friday, the highest snowfall total reported is 8.8 inches near Finland, Minnesota, west of Lake Superior. As of Friday morning, Duluth had received 5 inches of snow.

Winds gusted as high as 64 mph in Grand Forks, North Dakota, and 59 mph in Fargo on Thursday, leading to areas of blowing snow. Strong wind gusts have also been reported farther east on Friday, including near Duluth, Minnesota where a gust of 63 mph was recorded.

The snow and wind have resulted in hazardous travel conditions in some areas, including Ashland, Wisconsin where a local area emergency was issued midday Friday where portions of U.S. Highway 2 and State Highway 13 were closed due to extreme weather conditions. Duluth, Minnesota also reported numerous vehicle accidents.

This system is somewhat moisture-starved and only has marginally cold temperatures to work with – not to mention ground temperatures still warm from the summer and early fall – so exceptional snowfall amounts are not expected.

The jet stream will continue to plunge southward as this low-pressure system sweeps through, allowing colder air to infiltrate much of the nation's mid-section late this week. This jet stream nosedive will only amplify and lumber slowly east through the Great Lakes this weekend.

Temperatures are plunging into the 30s behind the cold front, plenty cold enough for snow to accumulate. These cold temperatures will linger around the western Great Lakes this weekend, allowing additional wet snow to accumulate in some areas.

The National Weather Service has posted a winter storm warning for portions of northern Minnesota, including the International Falls area, where heavy snow and wind gusts up to 35 mph are expected. This may lead to periods of low visibility with blowing and drifting snow into Friday afternoon.

A winter storm warning has also been issued for parts of far northern Wisconsin and northwestern Michigan into Saturday morning, where close to a foot of snow may accumulate.

How Much Snow?

The eastern Dakotas, Minnesota, Iowa, western and northern Wisconsin and the western Upper Peninsula of Michigan will see accumulating snow from this system.

The highest snowfall amounts will stretch from the Arrowhead of Minnesota to northern Wisconsin and the western Upper Peninsula of Michigan, where some locations could receive more than 8 inches of wet snow. These heavier totals are most likely in the hills just inland from the Lake Superior shore.

Minneapolis/St. Paul is currently expected to receive generally 1 to 3 inches of total accumulation by late Friday.

This snow will likely be of the heavy, wet variety due to marginally cold temperatures, as is typical with early-season systems.

Despite the lighter accumulations, driven by wind gusts to 60 mph, near whiteout conditions were observed in parts of eastern North Dakota and far northwest Minnesota, making travel dangerous.

The combined force of winds and wet snow may damage trees and trigger power outages from eastern North Dakota to the Upper Peninsula of Michigan.

If that wasn't enough, a second cold front and jet stream plunge will drop out of Canada into the Midwest early next week, with the potential of bringing more snow over the northern tier and Great Lakes in time for Halloween.

Interestingly, October snow in the Twin Cities has been relatively rare this century. This would be the first time it has happened there in eight years.

Last year, the first measurable snow in Minneapolis/St. Paul didn't occur until the third week of November. The previous season (2015-16), it wasn't until Thanksgiving Day, almost one month later than this upcoming snow event.
