2 points.
1. The models simply cant get the long range past day 7 correct and will continue to flip flop as with conflicting telecommunications (dipping PNA, NAO, rising EPO, and unclear AO. MJO clearly avoiding the warm phases in the near term as well.
2. Even if the pattern for the next 20-30 days looked like complete and utter crap and was locked in (counter to point 1 above). who cares? It would take a nearly perfectly times storm with perfect PNA/NAO/AO combination for it to actually snow and stick in November (and even early December). In the meantime, any small snow and cold is just a bonus and way ahead of schedule. The artic blast of early November completely got everyone to false start. Take a deep breath. Its Nov. 18th. The atlantic ocean is in the mid 50's. Let it cool a bit for a few weeks. Lets talk December 1, which is still extremely early. I believe Dec 15-Mar 15 is meteorological winter.
