The polar vortex split will help cause temperatures to plummet and potentially set the stage for some snowstorms. A recent strong "sudden stratospheric warming" event has caused the vortex to weaken.

The science behind the polar vortex is incredibly complicated, and we've only recently begun to understand how changes at our planet's poles impact weather at more moderate latitudes.
