A blizzard affected most of northeast Montana, beginning during the late morning and early afternoon hours on the 10th. Strong low pressure dropped south out of Saskatchewan and into central North Dakota during the afternoon and evening.  A strong cold front associated with the low swept across all of northeast Montana during the afternoon.  Northwest winds increased to 30 to 50 mph with many areas reporting frequent gusts to 60 mph.   A peak wind gust of 77 mph was reported in Glendive during the afternoon.  Periods of snow fell during the afternoon and night. Most of the snow that fell was light and snow accumulations were generally on the order of a couple of inches.  The strong wind produced severe blowing and drifting snow, and there were numerous reports of whiteout conditions with the visibility reduced to near zero.  By the evening of the 10th, all roads across northeast Montana were either closed, or open to emergency travel only. All roads connecting northeast Montana with North Dakota were closed at one time or another, including Interstate 94.  Many towns across northeast Montana were isolated during the afternoon and night time hours due to the road closures. At least a dozen people were stranded and had to be rescued by state and county road crews, who had to travel in near zero visibility.
