WANE-TV’s Shoup: Despite what you hear elsewhere, it’s not the Polar Vortex


Yep, its certainly unseasonably cool today. And you’ll probably here some folks attribute the cool weather to the Polar Vortex. As WANE TV’s Greg Shoup explains in his blog, we should take any such comments, even from “meteorologists,” with a grain of salt:

This typical July-like pattern will over the course of a few days be replaced by a ‘lobe’ from that ‘vortex’ or circulation that is referred to as the Polar Vortex. This concept is often misunderstood, especially in the national media as it is referred to simply as The Polar Vortex. This is scientifically inaccurate as the vortex or circulation itself moves very little. It has a semi permanent position near the Arctic Circle. That location does not vary and the vortex is never moving into a different location. However, sometimes we see a piece, chunk or scientifically called a ‘lobe’ break off this vortex and make its way to our region. This is not a common feature during the summer months so it is certainly very unusual.
