I was wrong on that....the stratosphere never really clicked like I thought it would. The attempt the second week of February ended up being a fake-out, which is where we parted ways with 2018....then we ended up succeeding in a reversal in early March, but it wasn't a true SSW and was kind of late, anyway by that point.
Disappointing finish to be sure, but I am happy overall with my outlook this year. I do need to fine tune how I develop my temp composites, though bc I wasn't cold enough...I'm still learning how to properly assimilate the role that CC plays in this. I think what I missed is that if the pattern is a dead-ringer for cold, which it was this year, then go nuts...don't water down the composites to account for CC in a generic sense because that is far too reductive a practice that will lead any forecaster astray. It can still get damn-cold, but it's just that the dice are now loaded against that particular outcome in any given region. The trick is to be a skilled and confident enough seasonal forecaster to identify those 1 or 2/10 seasons and go all-in. You can't be non-committal and meek, or else accuracy will suffer.
The truth is that I am remiss because I diagnosed this seasonal pattern about as accurately was any accomplished seasonal forecaster ever will, but I never fully committed to it, which was reflected in my temp composites.
