Just hearing the phrase “Polar Vortex” can make you feel chilly. A polar vortex is described as a low-pressure weather system that originates in the arctic at the top of the northern hemisphere. Occasionally, these low-pressure systems break off into separate weather patterns and make their way south bringing sub-zero temperatures and winds with them. As these large cold fronts move south, they tend to blanket the large extremely large areas in North America lasting anywhere between 3-10 days. In the past, Polar Vortex patterns have been known to hit as far south as Florida.
