Polar Vortex on a Polar Coaster

I am compelled to look at the official weather forecast for this winter.  That's because Polar Vortex is in the title.  What about the Polar Coaster that was predicted just a few weeks ago.  Add to that - Global News tells us to brace for Game of Snows, according to the Old Farmer's Almanac.

With this many catchy titles, I wonder what the  Weather Channel's official forecast looks like.  Let's check it out.

It is visually very compelling: The weather map is brilliant colours - a big deep blue circle in the middle of the country, a light blue circle that surrounds it which includes Toronto, Montreal, Edmonton and For McMurray, a third green circle, and finally two red circles.  You can imagine that red is above normal for average temperatures.  Then there are charts for snowfall/precipitation.  


Their headline on the Polar Vortex is to get ready for a classic Canadian winter.  That sounds like we have a polar vortex every year.

The Great Lakes  are a concern. Why is that?  Water levels are well above normal - so there would be flooding in spring if there is a cold and snowing winter.


The overall map shows a pattern or warmer temperatures all along the North American west coast, and below normal in the majority of the east and central portions of North America.  

You can see the Weather Network maps HERE.  

I expect it to be a cold winter when I compare this year's snow in mid-November with last year. Here's a picture from last year at the same time. 

We can look to the promise of spring below - the weeping cherry tree on Niagara Street, in St. Catharines.
