I dont know, but us winter weather folks need to figure out what is causing all the BN temps and AN precip, NAO blocking, PNA ridging so that we can repeat this in DJF rather than MAM next year. If it means cancelling flights and closing factories I'm all in. Anything for a return to solid winter regimes during actual winter months. Obviously I mean this tongue in cheek....I dont want airlines or factories closed and job etc in jeopardy. But seriously, something's gotta give with these winter patterns occurring well into springtime.
