“When did they change the Jet Stream to Polar Vortex ,LOL”
Due to the rotation of the earth, there’s almost always a polar vortex. Every so often, it slips out of its usual range and heads south. That’s what distinguishes it from the “Alberta Clipper” and other jet stream-driven cold fronts. The confusion arises because every excitable TV weatherman decides to spice up their reports with these slangy phrases.
I always liked “Alberta Clipper”, it has a romantic ring to it.
