Strengthening low pressure is expected to move from North Dakota into the western Great Lakes by Friday. This storm will provide the first blizzard of the season for portions of the western Great Lakes, upper Midwest and western Ontario. Strong winds will combine with 20cm (8 inches) of snow, to provide very poor travel weather along the Trans Canada Highway either side of Thunder Bay, Ontario by Friday morning. As this storm pulls east, a strong cold front will sweep across southern Quebec late Saturday. Temperatures will plummet from near record highs Saturday, as the coldest air of the season arrives. Daytime temperatures on Sunday in Montreal will actually fall most of the day. Overnight lows by Monday morning may be as cold as -5C (23F), with daytime highs on both Monday and Tuesday near 1C (33F). There is also a good chance rain will develop late Saturday and mix with snow by Sunday evening into Monday. Accumulations are difficult to pinpoint at this time, but expect slippery driving conditions early next week. Looking ahead into the middle and late portion of next week, the weather will remain cold in southern Quebec, with another chance of rain and snow by Thursday.
