    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.  

     

    That's really interesting.
