The durable -NAO isn’t crazy. Ensembles keep correcting to more -NAO in the long range the last several days and in theory a strat PV disruption would reinforce it as well.
Agreed. I don’t think there’s enough runway left to get to a solution that gives frozen precipitation to the metro corridor. Far N/W still in the game for something.
There have been plenty of signs in op runs and ensembles that we probably get a respectable arctic push from this pattern and both GGEM and GFS show it today. That probably means cold/dry for a couple days outside snow showers with the arctic front. Question then becomes if we can throw some moisture back over the cold air as the TPV retreats back to Canada.
