Winter storms are forecast for some provinces, brief above-seasonal temperatures for others

Toronto: While snow and cold will reportedly set in some provinces, brief above-seasonal temperatures will be experienced by others.

Although places like southwest Ontario saw temperatures hit the double digits, and Toronto with 14 C weather on Wednesday, according to an Environment Canada advisory issued in Ontario Monday morning, five to 10 centimetres of snow is possible in some areas.

Snowfall, expected to last through late morning and afternoon, depending on the area, was reported by Environment Canada’s weather alert.

Most of the snowfall accumulation within a couple of hours would cause reduced visibility in heavy snow, the weather agency said.

A mid-week storm is expected in Ontario and Quebec, bringing wet and thunderstorm-like conditions and warm temperatures.

With an expectation of a mid-week storm in Ontario and Quebec, wet and thunderstorm-like conditions and warm temperatures would prevail with a dramatic drop in temperatures on Thursday, before a rebound on Friday,

A flash freeze warning has been issued in Quebec over the sudden changes in the middle of the week with temperatures forecasted to drop 10 to 12 C within a few hours.

Parts of Quebec will also experience snow squalls, expected to be intense, brief, heavy snow with near-zero visibility, according to Environment Canada.

Chilly temperatures with 10 to 25 centimetres of snow and blowing snow, wind gusts of up to 60 km/h with reduced visibility  are expected in Alberta and the central parts of the Prairies.

An extreme cold warning was issued by Environment Canada for the northern Prairies with wind chills hitting -45 to -50 before tapering down.

Winter storm warnings with 10 to 15 centimetres of snow and strong winds were issued for the B.C. mountain passes.

Metro Vancouver and Fraser Valley areas can expect a wintry mix of precipitation from Tuesday evening through Wednesday with a risk of freezing rain as warm air overrides the cold air in some areas.

While no weather alerts were issued for Atlantic Canada, the Northwest Territories, and Yukon as of Monday morning, a single extreme cold warning was in place in Nunavut, where the area near Resolute is dealing with wind chill values near -55.
