I will be monitoring this blog, in addition to my twitter @BrettAWX and the AccuWeather.com Canada weather forum into this afternoon. I will be happy to respond to any questions or comments about the winter forecast, but try to keep them short and to the point.
Mild air masses likely to outnumber the chilly air masses for a good part of October.
Jet stream pattern across North America will become amplified across North America into next week, which means more extremes in weather.
Warm weather will dominate in the eastern half of the country for the next week. Pattern change possible during the last week of September.
The jet stream will strengthen from the Pacific across southern Canada over the next 1-2 weeks which will keep any sustained chilly/cold air masses up across western Alaska and eastern Siberia.
The latest clues to the long range into the month of October.
Late-season heat in the East and mountain snow in the West. Welcome to the fall season!
