Winter isn’t over yet! A polar vortex is bringing subzero winds, frigid temperatures, and possibly snow to the U.S., including snowbird states like Florida. National weather agencies and meteorologists are warning folks of a "shivering weather pattern" that’s forecasted to go into effect tomorrow and linger through next week.

Preparations are underway as an arctic blast dives into the nation's interior and southern regions and pushes a snowstorm into the Mid-Atlantic and Northeast that will be followed by lethal cold.

A blast of frigid Arctic air is expected to sweep across the United States beginning today, bringing unseasonally cold weather and possible snow or other winter precipitation to.
