Over the next few days, meteorologists will make a fuss about "record low maximum" temperatures being achieved in cities across the southeast. What does that term mean, anyway?

Weeks after The Vane coined the defining term of summer 2014 — SummerPolarVortexmageddon — another huge cool-down is on tap for next week, and everyone is hopping on the "polar vortex" bandwagon. Imitation is the sincerest form of flattery.

Temperatures in the northern United States will get relatively cool next week, with models suggesting temperatures ranging 10 to 20 degrees below normal. The cause is something we'll call the SummerPolarVortexmageddon, because it sounds cool and (still) nobody knows what a polar vortex is, anyway.
