The Return of the Polar Vortex?

How could we ever forget last winter?   It was probably the coldest and snowiest in a generation, thanks in part to that "polar vortex".

From the journal 'Nature Communications',  according to researchers, polar vortexes could become more frequent because of shrinkage in ice in the seas off Russia.  With less ice, more energy would be released from the ocean into the air, and that would weaken the atmospheric forces that usually keep the cold air trapped in the Arctic.

According to the Old Farmer's Almanac, winter temperatures will be well below normal, while precipitation and snowfall will be above average in the upper Midwest.

So, if the experts are right, we'll see less snow, but more sub-zero temps this winter.

They've never been wrong, have they?
