Ok in your feb 2010 map, most of the cold was in siberia but that secondary lobe of cold was right where we wanted it for it to work for us.
This year? The secondary lobe was centered in CA. It snowed all the way down to where it rarely snows, and I’m not talking about climo at 8,000 ft which is irrelevant for us. What’s relevant is where that cold air predominantly goes.
This is why I remain optimistic that we will still get big snow years, even while we lose the smaller events in most other years.
