NEW YORK (PIX11) - It's the middle of July and a polar jet stream is indeed headed our way -- but veteran PIX11 weather forecaster Mr. G doesn't want you to call it a "polar vortex."

"We can call it 'Cool Canadian air,' we can call it 'A package from Canada,' we can call it 'From Canada with love,' we can do a lot of things here, this is very typical," G said.

Heading into this weekend and perhaps lasting through next week, the jet stream is in a position that would eerily look more like January. A highly amplified Jet stream will be in place with the dip, or trough, over the eastern half of the nation.


With the help a strong Canadian High, well below temperatures will affect a good chunk of the Eastern US through next week. The Climate Prediction Center was fairly confident in its 6-10 day outlook that this anomaly will occur. The National Weather Service has indicated that many places in the east could end up some 10-30 degrees below normal.

Of course, with summer in full swing, a 30 degree below normal temperature will not have the same impact as it would during the middle of January.

"The polar vortex should be for the winter, sustained, not for the summer when we've had three 90-degree days."  said Mr. G.


The Polar Vortex is something that has always been present during the ENTIRE year. Sure, it gets weaker during the summer months but it is still there regardless.

The weather maps are showing what looks very similar to what happened this past winter. Purists will say that this event is not associated with it due to numerous technical reasons beyond what could be stated here.

In today’s world, the term gone beyond its true meteorological meaning and now the general public refers to it anytime it gets unseasonably chilly.

A few local weather service offices have already used the polar vortex term despite its real meaning.

At the same time the National Weather Service office in Tulsa have even hashtagged #notpolarvortex in one of their technical discussions.

    “As the planet was warming (1979-2001) the jet stream was moving north, at a speed of 12-13 miles per year (the polar convective cells were shrinking). Now that it has stopped warming, the jet stream is gradually shifting southward (the polar convective cells are growing): “Instead of circling the earth in the far north, the jet stream has begun to meander, like a river heading off course. This has brought chilly Arctic weather further south than normal, and warmer temperatures up north. Perhaps most disturbingly, it remains in place for longer periods of time” (“Jet Stream Shift Could Mean Harsher Winters”, Discovery)
