Another round of snow is expected across the Northland on Thursday.

Following Tuesday's snowfall of 4-5 inches in parts of Duluth, Carlton County and the South Shore of Lake Superior, some areas could accumulate even more Thursday.

The National Weather Service in Duluth forecasts 4-7 inches in the southern portion of St. Louis County as well as most of Carlton and Aitkin counties. The model has shifted farther to the south than previously predicted. Less snowfall is expected in northern St. Louis, Lake and Cook counties.

The snow will move primarily east across the region and is expected to arrive between 6-9 a.m. Thursday in Carlton County and the southern two-thirds of St. Louis County. Farther north and south, the snow is expected to arrive between 9 a.m. and noon.

The worst conditions will be Thursday morning and early afternoon, according to the weather service. Temperatures are expected to drop below freezing late Thursday afternoon and early evening leading to slippery roads. Snowfall should end Thursday night.

Northwestern Wisconsin will experience different precipitation types, although the newest storm model primarily predicts small amounts of accumulating snow.

The weather service reported high confidence in at least 4-6 inches of snow accumulation as well as low visibility and slick roads for most of the Northland, including the Twin Ports. The weather service reported less confidence in snowfall totals across higher elevations of the North Shore and the I-35 corridor.

Like Tuesday's snowfall, Thursday's snow will be wet and heavy.
