it is a complete outlier and is trending towards the other models. i have no reason to trust it at this point
also, the trend this winter has been to strengthen the Pacific jet, if anything, so the trends towards other model guidance make sense IMO
this event seems to come down to how zonal the Pacific jet is. the GFS is trending towards a more zonal Pacific jet, which helps boot the S/W out of the west instead of letting it dig. this is key to getting a coastal storm here
the trend is continuing on the 12z GFS... look at the E PAC ridge weakening and the increase in interaction between the S/W and ULL over the Pacific. look off of the CA coast. the increased strength of the PAC jet leads to a much weaker S/W this run

the progression on the EPS is quite similar to that of Feb 2021 with the vigorous S/W getting forced underneath the block. it's not very far off. what a shift here
just keep in mind that this is not the end solution at all... but the overall synoptics might not be failing us as we previously thought. gotta trust the pattern to produce
it's clear that the relationship between the Pacific jet and S/W is extremely delicate and OP runs won't really show us much when the setup is this chaotic. the Pacific jet has also been undermodeled all year, which actually works in our favor this time. just wait for the EPS
GEFS is night and day. love seeing the trough link up with the confluence as well. block is farther N, leading to a lower chance of linking with the height rises ahead of the trough
great run. this is a major step in the right direction

GFS is slightly improved. notice the lower heights out in the E Pac at the same latitude of the trough on the WC and higher heights towards AK
this is a shift towards more Pac jet interaction and the ECMWF solution
