You got them precip maps? ?CMC is more like the GFS this run View attachment 56503
Goodness. That’s wet....said that a time or two before.
Some members are basically a few degrees away from some paste bombs, 850s are thereGoodness. That’s wet....said that a time or two before.
Historically, in -NAO/-AO/+EPOs, the +EPO backs off some and the AK vortex retrogrades towards the Aleutians, opening up the door for +PNA
I played around w/ a few composites, I think this is as close as I can get at a monthly scale for the hemispheric scale pattern in a -AO/-NAO/+EPO during Dec.
I even used an older, cooler base period to try and bias the temperature composite warmer but it's still arguably vodka cold.
