A ground blizzard is expected tomorrow into the Red River Valley. For a description of a ground blizzard, please view our previous blog post here (click). An Arctic cold front will bring strong winds, which will funnel through the Red River Valley in southern Manitoba. Winds will be especially strong on the southeast side of Lake Manitoba.
These strong winds will easily blow any fresh snow that fell today and any snowpack across Manitoba. This will lead to significant blowing snow and possible highway closures. Depicted above/below are forecasted highway conditions for Manitoba and North Dakota/Minnesota on Sunday morning.
Potential highway closures depicted above are as follow for Sunday morning:
Highway 75 from Winnipeg to US border
Hwy 2 & 3 from Winnipeg
Trans-Canada highway from Winnipeg to Portage La Prairie
I-29 from Canadian border to Grand Forks, ND
Most highways in northwest Minnesota and northern North Dakota
...WINTER STORM WATCH REMAINS IN EFFECT FROM LATE TONIGHT THROUGH SUNDAY AFTERNOON... * WHAT...Blizzard conditions possible. Total snow accumulations of up to one inch possible. Winds could gust as high as 50 mph. * WHERE...Portions of northwest and west central Minnesota and northeast and southeast North Dakota. * WHEN...From late tonight through Sunday afternoon. * ADDITIONAL DETAILS...Plan on slippery road conditions. Widespread blowing snow could significantly reduce visibility. Gusty winds could bring down tree branches.
