    I agree with a lot of this. But why did you expect a +pna in a -PDO Nino?  There have been 4 Moderate/strong -PDO Ninos. None featured a +pna. Mean for the 4 is below.

    3 of the 4 were some of the snowiest winters in history here including 2010!  The one exception was 1973 which was a +QBO and has a crazy +++AO

    So if we agree that was an outlier and toss all 3 examples of a -pdo moderate or stronger Nino featured both a -pna and a shit ton of snow.  
     

    Actually if you simply take all moderate to strong ninos the mean is a -pna.  It’s only weak modoki ninos like 2003 and 2015 that feature a +pna.  But Baltimore averages 40” of snow in -QBO ninos despite the fact the pna is typically negative.  
     

    I never expected a +pna this winter.  My analogs that produced a mean snow of 42” were  -PNA city.  There is something else going on.  It’s not the pna because the pna was negative in past epic snowy ninos.  

     

    this is very interesting, especially 1964

    but to be fair though the block is defintely weaker than previously modeled, and the pac has gotten worse too

    i wish there was a way to properly compare the 500h archive maps on psl to what models have right now; do you still think the pattern is good and can produce considering the downtrends we've been seeing?
