As the end of the work week approaches, North Dakota is preparing for a blast of extreme cold that will easily rank as the harshest air mass we’ve seen so far this winter. Forecasters say this surge of Arctic air will bring dangerous to potentially life-threatening wind chills across much of the state from Thursday through Saturday. Low temperatures during this stretch are expected to plunge into the 20s and 30s below zero, with Friday shaping up to be the coldest day. In many areas, high temperatures may struggle to climb out of the teens below zero, even during the warmest part of the day.

While the cold hasn’t fully arrived yet, you still have a small window of time to prepare before conditions turn downright miserable. Taking a few simple steps now can make a big difference in staying safe and comfortable.

Check Your Heat and Safety Systems Before the Deep Freeze

Before the extreme cold arrives, take time to make sure your furnace is in good working order by replacing filters, checking vents for obstructions, and scheduling a service check if needed, since your heating system will be running nonstop. It’s also critical to test your smoke and carbon monoxide detectors, replace batteries if necessary, and confirm they’re functioning properly, as the risk of fire and carbon monoxide buildup increases when homes are sealed tight and heating systems are working overtime.

Your Vehicle Could Use Some Love Before It Gets Cold

Your vehicle also needs attention. Prepare a winter car kit that includes blankets, gloves, a flashlight, a shovel, first-aid supplies, snacks, and a fully charged phone or charger. Clear snow and ice from your vehicle’s roof, lights, and windows, and consider keeping sand or cat litter in your trunk for added traction if you get stuck.

Stock Up Now

At home, stock up on emergency supplies in case of power outages. Extra food, water, batteries, and warm drinks like tea or hot cocoa can be a lifesaver. Dress in loose, layered clothing when heading outside, including warm socks, sturdy boots, hats, and mittens.
