Brett Anderson, a senior meteorologist with U.S.-based AccuWeather, said the cool weather across parts of Eastern and Central Canada this spring will continue into the summer. He said Western Canada is expected to have a warmer and drier summer compared to normal.
“A persistent dip in the jet stream across Central and Eastern Canada will lead to an increase in spells of cooler air into the region, especially during June and July,” said Anderson in an online post.
The record extent of ice coverage this spring on the Great Lakes will carry over and have a cooling effect in those areas close to the lakes.
He said though Atlantic Canada and areas around the Great Lakes can expect a cool start to the summer, that should change to warmer and more humid conditions compared to normal during the second half of the season.
Though it is expected to warm up, the second half of the summer in Atlantic Canada is expected to be wetter. Anderson said moist air and heavier, tropical rainfall are in the forecast for the second half of the summer.
The Prairies and British Columbia can expect warmer weather this summer.
“There will be an increased threat for large wildfires in the far West later this summer due to the combination of warm, dry weather and the continuing problems with the [mountain pine beetle],” said Anderson
