Canada-Wide 2018-2019 Preliminary Forecast.
Finalized Outlook by Christmas!

Frigid Air and Heavy Squalls Loom

The winter across Canada for many this season is expected to be cold, particularly for Saskatchewan, Manitoba, Ontario, and Quebec.

Through careful analysis of meteorological data, we have compiled a preliminary forecast for the winter across Canada for this winter. We will issue an updated version, should the situation warrant, in December.

For many places, we expect an early start to winter. Some places in Manitoba have already received accumulating snow. For Southern Ontario, we expect accumulating snow perhaps as early as late October.

Key Highlights
– Frigid & Snowy Winter for Saskatchewan and Manitoba
– Cold & Stormy for Ontario and Quebec
– Potentially Historic Squalls for Great Lakes (NW and W Flow)
– Several Winter Storms for Maritimes and NL but Not All Snow

British Columbia
For this winter BC is expected to receive a relatively typical winter season. Normal precipitation amounts with normal temperatures will be present in the region. While a few colder outbreaks are certainly likely with some snow getting into the mainland, we expect nothing out of the ordinary.

Prairies
From Alberta to Saskatchewan to Manitoba, we expect a frigid winter overall. While Alberta is expected to receive moderating temperatures throughout the winter from Pacific air flows, Saskatchewan and Manitoba are expected to be exceptionally cold, and at times, record-breaking with several rounds of ‘deep-freezes’. Precipitation is expected to be slightly above normal for Alberta, and above normal for Saskatchewan and Manitoba.

Ontario & Quebec
Ontario is expected to be overall, cold this winter. Northwestern and Northern Ontario are expected to parallel the frigid air likewise to the Prairies. With the set-up of the storm track this winter, we expect more rounds of Colorado and Texas lows to infiltrate the Great Lakes and Southern Quebec for the first time in what has seemed to be a number of years.
The cold air from Manitoba and Saskatchewan will provide flourishing variables to allow a well-above and significantly active lake-effect season in an NW to W flow. Preliminary indications represent a repeat of December 2010 across the region.

Quebec is expected to receive above-normal snowfall this year as several storms track through the interior NE of the USA this year. Temperatures will become vastly more frigid through Northern regions of the province.


Maritimes and Newfoundland & Labrador
While the Maritimes and NL are expected to be active this year, it is expected at times, slightly milder air will target the regions, therefore, not all systems this year will be snow-makers. The regions will certainly be stormy this year, but several storms may end up more of a ‘wintry-mix’, rather than snowstorms. Temperatures will be slightly more moderated at times, although at times, cold bouts are certainly likely.

Territories
The Yukon is expected to receive slight benefits from Pacific air and a slight ridge at times over Western Canada/Western USA, providing relief at times relative to the typical winter in the region. Conversely, NWT and Nunavut are expected to receive normal precipitation

Canada Spring and Summer Highlights: Summer to Arrive; Will…



Canada’s Summer Highlights; Spring Temperatures and Spring Precipitation Forecast: From TransCanada Weather

Through careful analysis of ocean temperatures, atmospheric patterns and continental, national and global temperatures, we have formulated and depicted our predictions across the country for Spring and Summer 2018.

Spring

Atlantic Canada
A relatively active storm track across the entire region as listed, will provide ample opportunities for a mixed bag of precipitation for eastern sections, with snow for western sections through late March into early April.

Parts of New Brunswick, PEI, Western Nova Scotia, Western Newfoundland and most of Labrador can expect opportunities for snow.

Temperatures will be below seasonal, particularly through early April and slowly begin to moderate from late April into May for all of Atlantic Canada.

Ontario and Quebec
A relatively active storm track will also be present particularly from late March into early April. Opportunities for snow exist, however, temperatures will likely be slightly too mild for significant snow accumulations. However, below seasonal temperatures and slightly above precipitation are expected until mid April.

Temperatures will begin to moderate particularly later in April and seasonal weather will become more prevalent and consistent in May.

Prairies
The Prairies will continue to remain fairly seasonal this spring with dry conditions at times, particularly later in spring; average precipitation early in the spring.

British Columbia
Much of British Columbia will experience warm surges of Pacific air with an inundation at times, of moisture from Pacific low pressure systems.

Northern Territories
The NWT are expected to be seasonal and dry for much of April and May.

Summer

Atlantic Canada
An active storm track at times will provide for soaking rains and isolated severe thunderstorms at times, throughout the summer. This summer will be fairly consistently warm across the entire region with periods of hot and humid weather.

Summer will arrive, but some time will be required.

It is expected that warmth will begin to build into late June through July and August.

Ontario and Quebec
An active storm track will provide surges of heat across the region, particularly in late June through August. Severe weather will make visits at times this summer, however, it is expected the early portion of summer will remain somewhat dry, and slightly cool, with active and a widespread severe risk building from late July into August.

There is reasonable certainty that June will provide some bouts of cooler and drier weather relative to the norm.

Prairies
The Prairies will receive a typical summer; warm with periods of stiffing temperatures, severe thunderstorms and large hail and isolated tornadic risks, particularly across Alberta and Saskatchewan.

British Columbia
British Columbia is expected to be slightly cooler this summer, although not exceptionally cool. Surges of hot and dry weather that typically show through July-September may be somewhat limited this summer, although not non-existent.

Its not all bad news for the BC coast as moisture is expected to be to the north and south.

Northern Territories
The NWT are expected to be seasonal and dry for much of June, July and August.
