A slow moving but persistent snowstorm was expected to drop 3-5 inches across much of the Northland overnight with another 3-5 inches Thursday before the system moves out of the region.

The National Weather Service in Duluth has issued a winter storm warning until 11:59 Thursday night from much of the region, including Duluth and Superior, with snow expected to snarl traffic Tuesday morning and maybe again Thursday evening.

The snow was expected to start just after dark Wednesday and speed up overnight and then linger into Thursday evening.

Areas near the North Shore and Minnesota Arrowhead could see up to a foot of new snow.

Two of the heaviest snow bands - where up to 18 inches was possible - were expected along a line from Bemidji to International Falls and in Northwestern Wisconsin's South Shore snow belt near Lake Superior.

A winter weather advisory was posted for central Minnesota, including the Twin Cities, with a blizzard warning posted for western counties in the state.

After the snow it's going to get cold again, with highs in the single digits Friday and lows in the teens below zero Saturday morning.

Duluth has had about six inches of snow already this month and nearly 50 inches for the winter season so far.
