It’s not officially winter yet, but morning commuters in many parts of Canada might have forgotten that little fact.

But as the bad weather moves eastward, the Maritime provinces will suffer most from this weather pattern.

As the storm moves through Ottawa, the capital can expect anywhere from four to eight centimetres of snow and areas along the St. Lawrence Valley and the Laurentians might get up to 15 centimetres.

The worst from the weather pattern that left a mess across the American northeast is expected to hit those areas Monday afternoon and continue through the night.

Snowfall will change to ice pellets and freezing rain overnight and into Tuesday, which will make for slippery conditions and poor visibility.

Parts of Nova Scotia and New Brunswick's Fundy coast are at risk for fog as well as icy precipitation.

Slow commutes in Toronto

A mix of light snow and drizzle made for a tricky Monday morning commute across the Greater Toronto Area and much of southern Ontario after light snow fell overnight across the region.

Environment Canada issued a special weather statement about freezing drizzle for the GTA and much of southern Ontario, including Durham and Niagara.

Pearson International Airport reported more than 50 weather-related cancellations and flight delays.

Travellers are being advised to check their flight status before heading to the airport.

Central Canada still in deep freeze

It remains unseasonably and bitterly cold in the Prairies with temperatures well below -20 for southern Manitoba today and close to the -20s for southern and eastern Saskatchewan.

Environment Canada has issued extreme cold warnings for parts of southwest Manitoba and a blowing snow warning to southwest Saskatchewan. 

"While temperatures will ease somewhat for southern Alberta, temperatures for the eastern Prairies will remain frigid. Cold air looks to remain in place for the eastern Prairies throughout the week," Scotland said. 

American travel woes

Over the weekend, a storm ravaged parts of the U.S., affecting commuters and Canadian travellers. The storm dumped heavy snow over the mid-Atlantic and created travel disruptions across the United States, greatly affecting the county’s northeast.

The ongoing storm hit the east coast hard, making roads treacherous and causing school closures.

Bad weather also affected states in the south and southwest.

Mississippi was without power due to sleet and freezing rain and a snowstorm hit along the Utah-Arizona border, leaving hundreds of travellers stranded Sunday night.

Freezing rain and ice continue to remain a problem, further complicating an already bad travel situation.

Thousands of airline flights were delayed over the weekend.

Northern Texas was unexpectedly brought to a standstill from the weather with more than 650 people becoming stranded on Sunday at the Dallas/Fort Worth International Airport.
