Residents of Door and Kewaunee counties are bracing for a significant drop in temperatures this weekend, with daytime highs struggling to reach the single digits and nighttime lows dipping below zero. The National Weather Service forecast shows highs near 9 degrees Saturday and lows around –1 degree overnight, with similarly frigid conditions expected Sunday and into early next week. Wind chills could make it feel even colder, posing risks for frostbite and hypothermia.  

County officials are urging residents to take the bitter cold seriously and prepare accordingly. In Door County, several locations will serve as public warming sites during the dangerous cold snap. These include the Senior Resource Center 8 a.m.–4:30 p.m., the Sturgeon Bay Fire Department is open 24 hours, and all Door County Library branches in Baileys Harbor, Egg Harbor, Ephraim, Fish Creek, Forestville, Sister Bay, Sturgeon Bay, and Washington Island. Additional fire departments such as Gibraltar and Sister Bay will also be open for warmth, especially if power outages occur.  

In Kewaunee County, Kewaunee City Hall will operate as a warming site during regular business hours to support those without adequate heat or transportation. Emergency Management maintains a list of shelters activated during prolonged cold periods that can provide refuge in schools, municipal buildings, and community centers.  

Officials remind the public to monitor forecasts, check on vulnerable neighbors, and limit time outdoors. Dress in layers, cover exposed skin, and keep pets inside. If heating systems fail, having blankets, extra clothing, and emergency supplies can be lifesaving.
