If I say the words Polar Vortex you would likely remember the extreme cold we experienced from December 2013 to April 2014. And, while we have been stuck under a resilient ridge since then with the occasional cut-off low from the Great Lakes, it’s been a rather warm, humid and stormy pattern.
Next week, typically the hottest time of the year, we will experience a huge shift from the heat and humidity to well below average temperatures as the next Polar Vortex is forecast to return. We certainly will not experience the extreme cold we did a few months ago but we could break a record minimum high temperature which for Wednesday, July 16th, stands at 77.
The National Weather Service has indicated that many places in the east could end up some 10-30 degrees below normal.
