A strong late season winter storm will continue to ramp up today over the Northern Rockies before the main low heads north of the border. Significant snowfall and strong winds will likely result in blizzard conditions later today and continue into the overnight hours, with the worst conditions mainly confined to the Northern Rockies. Even so, there could be a period of hazardous conditions on the adjacent High Plains as the system pulls out. Over a foot of snow is expected along the higher terrain of Montana and blizzard conditions will be possible even at lower elevations where snow will combine with strong winds to make for whiteout conditions northwest of the low track.
