After 3-5 inches of snow fell on the Twin Ports Thursday morning, another round of snow is expected Friday.

The National Weather Service in Duluth said 4-8 inches of lake-effect snow could fall on Silver Bay and parts of the North Shore at a rate of a half-inch per hour, and has issued a winter storm warning for the North Shore in Lake and Cook counties as well as a sliver of St. Louis County along the North Shore. A total of 2-4 inches of snow is forecast for Grand Marais.

The weather service has also issued a winter weather advisory for the rest of Lake and Cook counties, as well as the northern third of St. Louis County.

Snow is expected to begin Friday morning and end by Saturday morning with the worst conditions Friday afternoon and evening, the weather service said.

"Gusty southeast winds could lead to blowing and drifting snow along North Shore," the weather service said Thursday afternoon.

The rest of the Northland will likely receive similar amounts of snow as Thursday.

Duluth and Virginia could see 1-3 inches of snow while 2-4 inches of snow is expected in Ashland and Hurley.

The weather service has measured 46.6 inches of snow so far this season, making it the fifth snowiest start to a winter through Dec. 12.

The forecast has been updated Friday morning after the Weather Service released an updated situation report.

Thursday's snow leads to slick roads

Agencies were busy responding to crashes and temporarily closing roadways to traffic around the Northland on Thursday after several inches of snow fell across the region.

The Minnesota State Patrol responded to a Ford Explorer that lost control on an icy roadway while traveling along I-35 in Midway Township. The sole occupant of the vehicle was treated at St. Luke's hospital for non-life-threatening injuries.

For nearly nearly 20 minutes Thursday morning the Duluth-bound lanes of the Blatnik Bridge were closed due to a crash, said Superior Police Department public information officer, Bradley Jago, making that the second bridge closure in two days.

As of early Thursday evening, the Duluth Police Department responded to 15 crashes since 10 p.m. Wednesday, according to public information officer Ingrid Hornibrook, though it’s unclear whether snow and ice caused those crashes.

St. Louis County Undersheriff Dave Phillips said Sunday night’s freezing rain left “miserable patches” of ice on roadways. As a result, most of the crashes the sheriff’s office has responded to in the past few days have involved vehicles rear-ending other vehicles.

“It was just like (a) Zamboni ice-making machine for the entire region. Then we had snowfall on top of that so it is really amazing how slippery it is still,” Phillips said Thursday afternoon. “It's deceiving. You can really overdrive in conditions like this where people just get going way too fast.”

A few of the Thursday's highest snowfall from the weather service:

  • 6.3 inches in Grand View
