Meteorologists with AccuWeather.com say that the cool weather pattern that has dominated central and eastern Canada this spring will prevail into the majority of the summer — meaning cool temperatures though June, July and August for Westman.
The cool spells are being blamed on a persistent dip in the jet stream across central and eastern Canada, especially during June and July. In addition to the jet stream pattern, the record extent of ice coverage over the Great Lakes this spring has delayed the normal warming of the lakes.
The combination of below-normal temperatures and lower humidity levels, however, will reduce the threat for severe weather this summer from the eastern Prairies into northwestern Ontario.
Elsewhere in Canada, the summer outlook calls for a warmer, drier summer from Calgary west. The combination of increased heat and little rainfall, coupled with the ongoing Pine Bark Beetle infestation, will raise the risk for large wildfires along and west of the Continental Divide.
In Vancouver, British Columbia, the combination of high pressure and above-normal sea surface temperatures in the northeast Pacific will lead to a slightly warmer-than-normal summer with reduced chances for rainfall.
Atlantic Canada will experience a cool start to summer, but the region will transition to conditions warmer and more humid than normal for the second half of the summer.
For the first half of summer, near-normal rainfall is expected across most of Atlantic Canada, however, for the second half of the season, the region will transition into a period of above-normal rainfall as a more moist, southerly flow takes over with the opportunity for heavier, tropical rainfall late in the summer.
