CALGARY, PREPARE FOR EXTREME COLD!

I was looking “upstream,” for hints at what the weather will be like downstream, here in New Hampshire, after our Thanksgiving snowstorm, and I came across this Dr. Ryan Maue map at the Weatherbell site. It is an anomaly map, showing if temperatures are above or below normal, and shows the conditions 90 hours from now, on Saturday.

The map shows it will be a little below normal round here, in the fading north winds after our Thanksgiving storm, but then I look northwest to western Canada…

Yikes!  That light purple is temperatures more than 50 degrees below normal, Fahrenheit. In actual fact the coldest spots are off the color-code key to the right of the map, which only goes as low as 50 below normal.  If you look at the small writing at the upper right, you see the lowest is actually -63.6 of normal.  Double Yikes! (Click maps, or open-to-new-tab, to clarify and enlarge.)

In terms of actual temperatures, it looks like the core of that cold will touch -50, but Calgary may be to the edge and “only” get to -23. (-31 Celsius.)

They can keep that stuff up there, as far I’m concerned. For heaven’s sake! It isn’t even December yet!

My hope is that the cold clashes with the above normal air to the south, and brews up a big west-coast gale. Some models are showing California getting some needed rain as a storm hits them at the end of the weekend. If that storm would only suck in the cold, and swirl it around with Pacific air, it would be much milder when it came east.
