Winter '16 / '17 - Sudden Stratospheric Warming: Watch #1

A sudden stratospheric warming (SSW) event may be in the works for the last week of the month.

After weeks and weeks of a high-speed rotation ... polar vortex (PV) forecasts suggest a significant slowing / weakening.  Slowing of PV suggests a deep layer of easterlies (light blue; lower right corner) over the Pole.

A maturing of this scenario would portend Arctic air drainage into the mid-latitudes.
