Is the Warm Weather Ending Soon?

Thunder Bay – WEATHER – Sunday is another day with temperatures above seasonal normals. However it appears, at least if Environment Canada’s senior climatologist David Philips is right, that colder temperatures are coming. If Phillips is right, the weather term “Polar Vortex” is going to become the weather norm by the end of January. While the coldest temperatures of the winter are often in January and February, Phillips is predicting a shift in the jet stream. which has been allowing warmer Pacific air in recent weeks to block the colder Arctic air mass from moving south.

Phillips reports, “One of the indicators is the jet stream – a river of air that blows from west to east – that has been flooding Canada with a lot of Pacific air and southerly air. It acts as a fence to the vortex, keeping it in the north,”

“It’s not a sure thing that it’s going to happen. I’ve looked at our models and it looks like in the fourth week of January we will begin to see cold air plunging down from Manitoba to Quebec and into the Maritimes. In the Prairies it will be generally normal,” says Philips. “There’s nothing guaranteed with weather and it’s not often well understood to give us a precise forecast.”

The message is, lets enjoy the more seasonable weather while we can.
