Green Bay, WI – Dangerous winter weather is intensifying across northeast Wisconsin today as the National Weather Service upgraded parts of Door County to a Blizzard Warning, citing near-whiteout conditions and hazardous travel expected through Monday.
According to the National Weather Service Green Bay office, northern Door County — including Washington Island — is expected to experience the worst conditions as strong winds blow across the open waters of Lake Michigan and Green Bay. Those winds are forecast to significantly reduce visibility, especially in exposed areas near the lakeshore.
Forecasters say the storm will continue to evolve throughout the day Sunday, with rain gradually changing over to snow during the late evening. The heaviest snowfall is expected overnight into early Monday, when wind speeds increase further and conditions rapidly deteriorate.
The Winter Storm Warning has also been expanded southward, now covering much of northeast Wisconsin, including Brown, Outagamie, Winnebago, and surrounding counties. While snowfall totals may vary by location, blowing and drifting snow is expected to create slick roads and difficult travel across the region.
Officials warn that conditions will be most dangerous during the Monday morning commute, particularly in northern Door County, where visibility may drop to near zero at times. Travel is strongly discouraged in blizzard warning areas once winds intensify.
Residents are urged to prepare for rapidly changing conditions, monitor local forecasts, and avoid unnecessary travel during peak storm impacts. Power disruptions are also possible where strong winds and heavy snow combine.
