Dr. Judah Cohen from Atmospheric and Environmental Research (AER) puts out a blog every week during the winter with a review and analysis of the Arctic Oscillation (AO) and Polar Vortex (PV).
In the Impacts section he discusses the possible influence from a significant polar vortex disruption on the weather across the Northern Hemisphere.
This is a nice weekly summation.
