My wag is that the NAO would do what we want it to do (like March 2018) if the Pacific was 'workable' instead of downright hostile. The persistent placement and orientation of that PAC ridge since early Jan is god awful as it keeps the PNA significantly negative and the trough location is such that the boundary is almost always well to our west. Typically there is enough variation so there are periods where the PNA/EPO are more conducive for a favorable storm track. 

March 2018 was just before the latest PDO flip.  Most of Winter 2018 the PDO was still positive, it was neutral in March.  The pac was slightly negative but not crap like its likely to be much of the time the next 30 years now that we are clearly in a -PDO cycle.

 

Yes we will get some fluke lucky years where the PDO is positive even during this -PDO cycle.  But that will be very rare.  Probably only 1-2 times a decade.  And some of those will still be ruined by other factors, like if one times up with a la nina or a positive AO for example.  2018 was a positive PDO for example and not a great winter because it coincided with a +AO and a Nina.  SO...if 80% of the time we are going to have an extremely hostile pacific over the next 30 years...and some of the other 20% will get ruined by not timing the pac up with other factors...we are in trouble if a -NAO cannot offset an extremely hostile pac anymore because that is how we got the majority of our snow during the last -PDO.  We snowed with a downright god awful pac all the time during that era, because we had to, the pac was putrid most of the time.

A perfect summation of the winter thus far on the NWS warnings map emoji23.png

... why not throw a blizzard warning in the LA suburbs in there for good measure

Just for fun - point/click from some of those mountains north of LA:

Friday

Snow. The snow could be heavy at times. High near 28. Very windy, with a south wind 45 to 50 mph, with gusts as high as 75 mph. Chance of precipitation is 100%. New snow accumulation of 36 to 42 inches possible.
 
Friday Night
Snow. The snow could be heavy at times. Low around 21. Windy. Chance of precipitation is 90%. New snow accumulation of 16 to 22 inches possible.

@Ji you asked about the PDO... unfortunately we are only about 5 years into this current -PDO.  The last -PDO lasted for 35 years.  This is something I've hinted at a couple times, but its depressing... but what if the "snowy" period we've been waiting for here actually was the 2000 to 2020 period and it simply wasn't that snowy here because the climate was already degrading we just didn't notice as much because of the +PDO we were in.  But places not too far north of us were getting absolutely blasted with snow during that period while we were only about average.  What if that really was the very snowy cycle we were due for and we simply didn't take advantage of it because things were already getting warmer.  And now we are in another "down cycle" and its god awful instead of just bad.  

 

ETA:  this does not have to be a AGW debate btw.  Whether it's warmer because of a normal cycle that has nothing to do with AGW or not is irrelevant.  We can discuss changes in our snow climo without having to debate AGW.   

If true, this would be crushing.

If it's there at 12z tomorrow, I might kick the tires.  This time may be different.  We have some blocking

CMC has the block but still manages to plow a weak low into Erie. Pretty sure we have seen how this story unfolds. December threats with the block still turned into cutters. Skeptical at best for now.
