Dakotas in store for another Alberta clipper
BISMARCK, N.D. (AP) — Another Alberta clipper is bearing down on the Dakotas Friday, but forecasters said it won't be nearly as strong as the one that swept through earlier this week.
The storm that blew in from western Canada on Thursday snarled traffic, shut down schools and damaged everything from trees and flags to signs and buildings. The top wind speed in North Dakota was 75 mph; in South Dakota it was 76 mph. Sustained winds of 74 mph are considered hurricane force.
"We've had a series of clipper systems for the last 10 days or so, but this one, by far, was the strongest one," National Weather Service meteorologist Bill Abeling said. "It was a very potent system, one of the strongest clipper systems I've seen in a while."
An Alberta clipper is a fast-moving system that moves southeast out of the Canadian province of Alberta and into the Plains, Midwest and Great Lakes regions of the U.S. It typically brings light snow, strong winds and colder temperatures.
Another clipper is expected Friday night into Saturday, but with wind gusts of up to only about 40 mph, weather service forecasters said.
The agency posted a wind advisory for central North Dakota for late Friday and early Saturday and a winter weather advisory for northeast and east central South Dakota late Friday through Saturday.
Thursday's clipper brought colder weather, but temperatures this weekend are forecast to warm up again to levels experienced earlier in the week — in the 20s and 30s in North Dakota and in the 20s, 30s, 40s and even 50s in South Dakota.
Grand Forks, which was hit hard by Thursday's clipper, on Wednesday had a record-high temperature for the date, at 39 degrees. The temperature in the northeastern North Dakota city on Thursday didn't rise above zero.
