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.
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.
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.
Much of British Columbia will experience warm surges of Pacific air with an inundation at times, of moisture from Pacific low pressure systems.
The NWT are expected to be seasonal and dry for much of April and May.
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.
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 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.
The NWT are expected to be seasonal and dry for much of June, July and August.
