I can see that vis-a-vis 2015-2016. Super El Niños send the +p anomalies (nov/dec) into Southern Canada, and it’s still cold enough to snow—this in turn produces an early rock solid pack in our cold source regions. I believe that helped us out January-March 2016 as pattern shifted more favorable, but generally, not great.
Instead, this season, with Pacific being tame, Canada has been dry and most of the precip south….No pack build up. I’m definitely less optimistic for cold/snow than 2015-2016 from this point on.
