I was convinced that I was not going to see anything at my place. It turned out that I didn’t have to.

SnoSki14 Posted December 9, 2022 Share Posted December 9, 2022 GFS ticking south and colder for Sunday. If trends continue we should def get snow to mix in and northern areas may even pick up a light accumulation. With strong blocking more south ticks are possible vs the usual last minute NW ticks 2 Link to comment Share on other sites More sharing options...

Volcanic Winter Posted December 9, 2022 Share Posted December 9, 2022 I’m gonna let the weenie flag fly for the 16th and go all in on hoping for some decent snow down by the coast. Gotta see continued trend toward a solution that works for all of us, and I def see some potential there for a fun event. This weekend I’ll be happy if you guys catch some good flakes.

EastonSN+ Posted December 9, 2022 Share Posted December 9, 2022 While the GFS is unlikely we still have a -4 AO. So an offshore track is plausible. 1 Link to comment Share on other sites More sharing options...
SnowGoose69 Posted December 9, 2022 Share Posted December 9, 2022 Really comes down to how far north the system can initially get...anything from a track too close, perfect, or even a miss is possible at this stage. 2 Link to comment Share on other sites More sharing options...
