(Bismarck, ND) — Unusually warm weather is breaking records in North Dakota. The cities of Bismarck, Dickinson, Minot, and Jamestown all set high temperature records on Wednesday, with a high of 62 degrees in Dickinson. Temperatures in Bismarck reached 55 degrees, while a high of 57 was recorded in Minot, shattering previous records set in both cities back in the 1930s. According to the National Weather Service, a specific kind of weather pattern called an “Omega Block” is to blame. This type of pattern tends to block winter storm systems as they approach the region.
