SIOUX FALLS, S.D. (AP) -- Forecasters say the cold temperatures that are coming to much of the nation are rare -- maybe once a decade or more. But every once in a while, the icebox over the North Pole gets loose and this "polar vortex," as one meteorologist calls it, is about to get funneled as far south as the Gulf Coast.
The cold could be historic and dangerous. Parts of the central Midwest could also see up to a foot of snow. Some schools are already closed for Monday.
A winter storm that blanketed much of the eastern US with snow and bone-chilling temperatures is being blamed for at least 16 deaths.
Forecasters expect a weekend warm-up in some areas before temperatures plunge again.
