At some point on Thursday, December 28 during the afternoon the temperature dropped below zero across most of the region. It wasn’t until yesterday morning that the temperature got back above zero in most area. That means from anywhere between 100 to 120 hours the temperature remained below zero. North Dakota is a large state, so there are some exceptions, but generally speaking this was the longest stretch of below zero temperatures since December of 2004. We will continue to record mostly below average temperatures, albeit, warmer than it has been for the next several days. With the cold will come very little snowfall through the weekend.
