AccuWeather.comWe can only hold it off for so long, winter that is, and big changes are on the horizon. Cold air has enveloped most of western Canada and it slowly moving east. This morning it is -23C in Calgary, and -20C in both Edmonton and Regina. The cold will continue into next week across the west while slowly beginning to invade the east. A small clipper system will skirt along the US border tonight with scattered flurries and eventually showers in southern Quebec and eastern Ontario. Clipper systems are fairly weak with moisture limited to the immediate track, but a centimetre or two is quite possible in some locations, especially north of the city. Winds can be gusty with these low pressure areas and they will be tonight and Saturday. The light snow tonight will mix with rain by daybreak and eventually end Saturday morning. Temperatures will be chilly today but rise above freezing overnight. Winds will out of the southwest from 40-70km/h by Saturday morning, and slowly diminish by late in the day tomorrow.
Sunday another weak low will bring a similar weather day with flurries and showers mixed. The really cold air is expected to move into our region by late next week with the potential for a major storm to move from the deep south towards the Great lakes with snow and rain by Thursday in Ontario and Quebec. The first outbreak of lake effect snow is also quite possible by next Friday. This scenario has all the ingredients to become a reality, it will all depend on timing. I would keep this in mind and finish preparing your car and home for winter this weekend.
