According to our long-range formula, the winter of 2014–15 will see below-normal temperatures for about three-quarters of the country. A large zone of very cold temperatures will be found from east of the Continental Divide east to central Quebec. The most frigid temperatures will be found from the Prairies into the Great Lakes. The coldest outbreak of the season will come during the final week of January into the beginning of February when frigid arctic air drops temperatures across the Prairies to perhaps 40 below zero. As the frigid air blows across the Great Lakes, snow showers and squalls will drop heavy amounts of snow to the lee of the Lakes for such localities as Houghton, Goderich, Owen Sound, and Sault Ste Marie.
No region will see prolonged spells of above-normal temperatures; only near the Pacific Coast as well as eastern Quebec and the Maritimes will temperatures average close to normal.
Near normal precipitation is expected over the eastern third of the country, as well as British Columbia and the Prairies. Below-normal precipitation values are forecast for much of Ontario and around the Great Lakes, as well as western Quebec.
We are “red flagging” the first 10 days of January and the first week of February along the Atlantic Seaboard for active wintry weather featuring bouts of heavy precipitation and strong winds. Another red flag timeframe for widespread wintry conditions is centered on the middle part of March across the eastern half of the country.
