The atmosphere is preparing to send part of the polar vortex southward toward the US next week with an outbreak of arctic air and lake-effect snow.
The polar vortex is a large pocket of very cold air, typically the coldest air in the Northern Hemisphere, which sits over the polar region.
Occasionally, this pocket of very cold air can get dislodged farther south than normal, leading to cold outbreaks in Canada and the US.
The main blast of cold air associated with the plunging polar vortex will swing southeastward into the Central and Eastern states spanning Sunday, Nov. 9, to Friday, Nov. 14, 2014.

Our first frost just happened 2 days ago, and it typically happens on the 15th of October.
Oh, God, Hell hath thrown it's gnarly wrath when it gets cold in the late fall!
We must be doomed? LOL!
Polar vortex has been happening for decades, maybe even centuries or millennia, but the climate change crowd had to give it a scary sounding name. Thus we have the polar vortex to scare us every fall and winter.
Yawn
You mean it might get cold in November?
First and last.
It's because of global warming that it's getting colder
