Looks to me like the ECMWF, GFS & Canadian models have all come around to forecasting a stretched #polarvortex for mid-December. No signs of a related pattern in the troposphere, i.e., #cold air on the move across North America, but will models adjust in this direction with time? pic.twitter.com/NeRf3rBtLP
