National Weather Service-Bismarck Meteorologist Todd Hamilton says threatening wind chills are expected throughout the day Wednesday in the eastern part of North Dakota. The actual air temperatures could be as low as 40 degrees below zero in the east, into northwestern Minnesota. For the central and western part of North Dakota, it won’t be as cold. “Thursday morning, the coldest air goes to the east.” Hamilton says there will be a warming trend Thursday and Friday. “Temperatures will warm into the 40s by Friday in southwest North Dakota, and into the teens and lower 20s above zero in eastern North Dakota,” says Hamilton. “It will be more normal for this type of the year.” A friendly reminder, farmers and ranchers should dress properly for outside work. It only takes a few minutes to get frostbite.
