This raging +AO in my opinion has been the killer as far as snowfall. We can still get plenty cold with the AO on the wrong side but we need -AO if were going get the kind of snow storms were hoping for.
Looking back winters like 1993/1994, 2013/2014 and 2014/2015 are fools gold. They're anomalies that defy the odds. Now were always thinking we can score like we did in those years from a favorable EPO with no other support from the other indices. Sure the occasional wave can work out but it's not supposed to occur as frequently as it did in 14 and 15 where almost everything broke perfectly
