Polar Vortex

There’s a cold snap on the way.

At least one town in Wyoming has set a new all-time low for the month of November, and that arctic air mass is now barreling its way toward New Hampshire.

While it’s unclear to what extent this cold actually is a piece of the polar vortex, that doesn’t mean the vortex isn’t an important driver of New England’s winter Climate. Experts are debating if more extreme swings from warm to cold are part of what a changed climate will look like in New England.
