Of course, this is July, not January, so temperatures forecast to be roughly 10 to as much as 30 degrees below average won't have quite the same effect.Call it the ghost of the polar vortex, the polar vortex sequel, or the polar vortex's revenge. Meteorological purists may tell you it's not a polar vortex at all. However you choose to refer to the looming weather pattern, unseasonably chilly air is headed for parts of the northern and northeastern U.S at the height of summer early next week.

Bearing a haunting resemblance to January's brutally cold weather pattern, a deep pool of cool air from the Gulf of Alaska will plunge into the Great Lakes early next week and then ooze towards the East Coast.
