Waves of cold air could bring snow in November, new winter forecast shows
With temperatures steadily dropping and days ever shorter, it won’t be long before winter arrives.
AccuWeather’s long-term forecasters team has just released their annual forecast for the coming season.
La Niña is expected to shape some of the overall weather again this winter, but the next La Niña will be weaker, especially in the second half of the season, said AccuWeather senior meteorologist Paul Pastelok.
The first waves of winter are expected in the northeast in November, when Pastelok said there could be “a few rounds of cold weather and some snow”.
The risk of plow snow is also expected to start early in the season with this cold air.
Areas closer to the coast could also be exposed to cold and snow early in the season, but it should not be as cold or snowy as in areas further inland.
The severity and frequency of snow and cold air are expected to ease a bit by mid-December before returning in January.
“This is the month that stands out,” said Pastelok.
Indeed, the traditional “January thaw”, during which the cold air calms down a bit, may not arrive before February.
In addition, the polar vortex could be felt at the end of the season.
“In late winter and early spring, there could be another attempt to move or divide the polar vortex,” Pastelok said.
This would translate to freezing arctic air in the northeast, prolonging winter weather well beyond March 1, which marks the onset of meteorological spring.
