Updated Long-Range Forecast Model Outlook

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.
