Persistent Polar Vortex

Good evening.. its December and it sure feels like it outside also. As long as the circumpolar vortex is positioned over northeastern North America its going to be seaonably to unseasonably cold over the eastern US overall. Any forecast that tells you there will be longterm warm spells including teleconnections and/or model graphics should be taken very lightly and with a huge grain of salt. This feature is currently controlling our weather and doesnt look to let up anytime soon.
