STURGEON BAY — A significant winter storm is possible Thursday afternoon into Friday, that could bring heavy snow and strong winds to the Door County from Sturgeon Bay through Fish Creek to Gills Rock.

Blowing and drifting snow could make road travel very difficult in Northeast Wisconsin. Air travel will be greatly affected, according to the National Weather Service in Green Bay.

Decent winter travel conditions to Door County end Thursday morning and don’t return until Saturday morning on Christmas Eve.

Travelers coming to the Door County from the southern parts of the state will have the most difficulty Thursday or Friday.

winter storm watch already has been issued by the National Weather Service for counties in western and central Wisconsin.

A strong low-pressure system is expected to move directly over Chicago Thursday, bringing with it heavy snow.

But the most significant travel hazards will be Friday on the back end of the storm.

That’s when forecasters say blowing and drifting snow could cause whiteout conditions and make road travel impossible.
