The weather systems are switching from snow to cold, according to Nathan Heinert, meteorologist with the National Weather Service in Bismarck.
Wind chill warnings have been issued for much of North Dakota through noon Friday. Heinert said the cold would continue through the weekend with more wind chill warnings likely to be issued.
“The wind chills are going to be mainly around 30 (degrees) below,” he said. “We’re going to continue below zero for highs through Saturday.”
Heinert estimated air temperatures will be about 20 degrees below the seasonal average of about 20 degrees for a high and zero for a low in Jamestown.
Forecasted highs for Sunday are above zero but that break in the cold weather is short lived.
“Then we get cold again for early next week,” Heinert said.
Snow amounts Wednesday night into Thursday were heaviest to the north and lighter south of Jamestown. The heaviest snow reports came from the Harvey and Courtenay areas with 6 inches. Measurements taken at the North Dakota State Hospital showed Jamestown receiving 4 inches of snow while Ellendale and Ashley each reported 1 inch.
The North Dakota Department of Transportation closed Interstate 29 between Fargo and the Canadian border and issued no travel advisories for the Devils Lake and Grand Forks areas Wednesday night. Interstate 29 was opened and the travel advisories lifted Thursday.
The city of Jamestown moved its snow-plowing operations to residential areas at 11 a.m. Thursday. Plows were expected to continue work in the downtown area at 11 p.m. Thursday.
Heinert called the current weather the second cold snap of 2018 even though we are less than two weeks into the new year. He also forecasted a break in the weather.
“By the middle to late next week we’ll break out of this cold snap,” he said.
