So, it looks like the snow is going to start around 16:00 localtime and then be in full blizzard mode by about 18:00 tomorrow. Well, maybe not an official blizzard per Environment Canada’s definition (four or more hours of snow or blowing snow with winds of 40 km/hr or more, visibility reduced to less than one km. in snow and/or blowing snow, and a windchill of -25 or colder) but definitely lots of snow and wind.
