High pressure system expected to change weather for Eastern Canada

There is a potential change brewing in the weather bound for Eastern Canada in the coming weeks.

According to Drew Lerner of World Weather, Inc., what we’re looking for is a high pressure ridge to develop in the central United States, cranking the jet stream around.

“It’ll form a northwesterly flow into southeastern Canada,” explains Lerner, in this excerpt from the Monday edition of RealAg Radio. “So Ontario and Quebec will start seeing their weather systems coming in from the northwest instead of the southwest.” (continues below player)

A system like this, expected to develop in one week to ten days, usually means less precipitation, says Lerner, though it may also make for cooler temperatures.

Looking out a little further, Eastern Canada can expect less hostile weather into the summer, so planting beyond the insurance date may not be a bad idea in some areas.

As for harvest season?

“I think the fall is going to be largely dependent on what happens to El Nino,” he says, adding if it sticks around it could generate a cooler bias for Ontario. It is expected to gradually weaken throughout the summer, however, and if it does, we can expect temperatures to hold up slightly.
