This is my latest interpretation of the fairly reliable ECMWF (European model) weekly long-range forecast model output for North America, which now goes out through the week of Dec. 17-23.
Keep in mind, this is not a forecast from AccuWeather.com or myself, and this does not necessarily have to match up with the AccuWeather.com 25-day forecast.
Although this model is showing widespread warmth from Dec. 3-9, it does appear that a batch of cold air could get drawn down into eastern Ontario, Quebec and the Northeast U.S. between Dec. 5 and 7.
Based on the overall upper-level pattern that I expect for the second and third week of December, I do feel that this latest ECMWF forecast might not be cold enough from Manitoba and Ontario then into the eastern U.S.
Do recent cold weather events signal an early winter for Canada?
Here are my latest thoughts on upcoming weather pattern highlights across canada for the next few weeks.
