Cold Retreats Later in the Month

Latest forecast model data and teleconnections support the idea that the widespread cold pattern will gradually fade way during the last week of the month and perhaps into at least early December. However, I do not currently see any signs of prolonged warmth either, so it may be more the case of trending back to normal or slightly above-normal across central and eastern Canada.

However, the overall pattern as we head into the first two weeks of December could still exhibit a fairly amplified jet stream pattern which could lead to some significant storm systems tracking from the Rockies and up toward eastern Canada.

The maps below are basically a reflection of what the latest European (ECMWF) weekly long range forecast model is showing into the second week of December. I also factored the latest CFSv2 a little bit as well. These are not my or AccuWeather's forecast.

Keep in mind, the European weeklies have been going through a rough stretch lately in terms of pattern recognition, thus confidence in the model remains lower than average, especially for the December panels.
