-PNA/+NAO Combo Looking Unfavorable for Snow

The 12z model suite is indicating that the window of opportunity for February potential snowfall is closing. The PNA is looking to drop into a raging negative phase, and the NAO looks to move towards a moderate positive phase. This combination is not a good sign for snow lovers.
Additionally, the 12z GFS ensembles appear to be showing the infamous polar vortex re-forming over north Canada, which would only continue to delay or even cancel any further snowstorms.
