(CBS Local) — If you think it’s cold now, brace yourself. Weather researchers say that a polar vortex could hit the United States and Canada with extremely frigid temperatures either by the end of this month or in January.
Judah Cohen, a climate expert at Atmospheric and Environmental Research, said the latest studies indicate there is a chance Arctic air could push southward and blanket much of the Northern Hemisphere in late December or early January.
