This whole ‘polar vortex’ thing is just getting silly, and on a par with ‘global warming’.
These ‘polar vortices’ are pretty much a constant round the globe.
Here, see for yourself.

I assure you that the polar vortex which caused our “Winter That Would Never End” early this year was quite real.
The pattern shown here is exactly the same picture that was shown to everyone all winter long - that's why people are referring to it as a “polar vortex”, although that's not exactly what the meteorologists are calling it.
And it looks like it's going to bring temperatures down into the 40’s, which is almost unheard of here in July - again, quite real (for us anyways).
