It’s called Artic Blast!!!
That would be the term I remember. I just looked up vortex in the dictionary:
vortex: 1. A mass of whirling gas or liquid, esp when sucked spirally toward a central axis; a whirlwind or whirlpool. 2. Any action or state of affairs that is similar to a vortex in violence, force etc
FWIW, I haven't been vortexed yet.
As the Binghamton NY weather guy said one night it’s “that cold canadian air coming down out of Canada!”
My wife and I nearly busted a seam laughing!
