It's been a quiet morning on Thursday for much of the region, but the snow is slowly moving eastward. Snow will continue to take over the Northland through the day and will be heavy at times. This, combined with gusty winds will reduce visibility.

A Winter Storm Warning is in effect for South St. Louis, Carlton, South Cass, Crow Wing, and Aitkin Counties until 1AM Friday and for Douglas County in Wisconsin until 7AM Friday. The WDIO Storm Team says there is the potential for 6-9 inches from the Brainerd Lakes region eastward to Duluth, and along parts of the North and South Shores. Forecast details here.

There's a widespread chance for 3-6 inches of snow for much of the Northland. Communities immediately near the shorelines will have lower accumulation, in the 1-3 inch range, due to warmer temperatures. Koochiching and Northern St. Louis Counties will be on the lower end with this storm, receiving 1-3 inches.

Winds will begin out of the east in the morning and gain strength by afternoon, eventually shifting out of the northwest behind the system Friday. Waves on Lake Superior will build until that wind shift kicks in, reaching heights around 4 to 7 feet. Steady snow may linger along the South Shore through Friday morning. It will be otherwise chilly and breezy with mostly cloudy skies and spotty light snow showers.

Much of the rest of the region is under a Winter Weather Advisory. This includes Cook, Lake, Itasca, and Central St. Louis until 1 AM Friday. Pine County in Minnesota and Douglas, Bayfield, Ashland, and Iron Counties in Wisconsin and Gogebic County in Michigan stay in the Advisory until 7 AM Friday.  Anywhere from 3-6 inches of snow is possible, with some higher amounts on the South Shore.

There is some uncertainty with the southern edge of the forecast area as there will be a transition to a wintry mix or all rain the further southeast you go, so there is the potential for a shift in the location of the heavier snowfall.

Some sleet or freezing rain may mix in with the snow at times at this transition zone.

Roads conditions will deteriorate quickly across the Northland starting around 8AM. Visibility will be reduced in the Winter Storm Warning with heavy snow and blowing snow.

Snow looks to last the majority of the day Thursday and into Friday.
