Last Winter's Cold and Snowy... This year???
"The circumstances are definitely different as we move toward the start of November this year. While an El Nino is not officially in place by government definition, we do see many of the signals of an El Nino across North and South America. Another stark difference from this time a year ago is the complete lack of blocking across Canada and the high latitudes in general. The main polar vortex has been making a home on the Asian side of the northern hemisphere so far this fall, not across north-central Canada.
These differences from last fall could have a major impact on our winter's weather if they stay in place. The current pattern as it is set up would favor a mild weather pattern with infrequent periods of precipitation across the Prairies. The million dollar question is whether and how long can this pattern maintain itself?
Model projections are indicating that we may look forward to more mild weather well into if not through November. A mostly west to east flow is forecast across Canada and the U.S. for the coming few weeks which brings lots of Pacific air inland across the North American continent. This air is quite mild versus normal at this time of year.
The pattern as it is shown now prevents the development of Arctic high pressure across northern and northwestern Canada. The cold air making machine of last winter is nowhere to be found for now."
I could like global warming!!!
