A Classic Canadian Winter is Coming

Despite some of the warmer weather we are seeing these past few weeks, Chris Scott of the the Weather Network reported last week we are still expecting a winter!

"As a whole, Canadians should expect a wild ride from start to finish,” Chris Scott, Chief Meteorologist at The Weather Network, says of Winter 2017/18.

"It's safe to say we’ll all be participating in winter this year."

The Precipitation Picture

We expect that most of Canada will have above normal or near normal precipitation with the most active areas stretching from the Great Lakes to the Maritimes and southern Newfoundland and also from southern B.C. to southern Saskatchewan. Colder than normal temperatures are expected across a large part of central Canada with near normal temperatures expected for most other areas.

Exactly what is La Niña, though?

• It is a large-scale climate pattern associated with cooler than normal water surface temperatures in the central and eastern equatorial Pacific Ocean
• It has the opposite pattern from El Niño, which is associated with warmer than normal ocean temperatures in the central and eastern equatorial Pacific Ocean
• No two La Niña events are exactly alike, but La Niña has a reputation for focusing the coldest and most active winter weather across Western Canada, with a more variable, but often milder and stormy pattern from the Great Lakes to Atlantic Canada

For most of the country this will include an extended period of milder weather – a longer than typical thaw for southern areas and a period of less harsh winter weather further to the north where seasonal temperatures are well below freezing.

A classic Canadian winter is expected for this region with an active storm track bringing above average snowfall across central and southern regions. There is also a heightened threat for freezing rain at times across the south.

A stormy weather pattern could bring the Greater Toronto Area its snowiest winter in a decade. In fact, it is interesting to note that there are some similarities in the global weather pattern between this year and the winter of 2007-2008, which brought Pearson airport its snowiest winter on record.  The cold will be the bigger story across northwestern Ontario with colder than normal temperatures expected. However, the pattern will relax at times with an extended period of milder weather expected mid-winter.
