I think it’s coming, I hope. The GEFS rushed things as usual. The key is getting the trough in the west coast to the south/aleutians and drive our +PNA/-EPO.

I feel the -EPO is the real way we're going to get our good sustained cold if we're going to get it. That's been what we've depended on for the last several years. I just doubt there's going to be any sustained -NAO block with 50/50 low to get us cold and stay cold. If we do get it, I'd bet it's transient and temporary. We literally need to thaw Alaska with a nice -epo ridge for persistent cold imo. My concern is the gefs is playing into it's bias, we don't get a true -EPO pattern change and we're going in to a limited cold window in the 10 day that will come and go pretty quick.
Rooting for the gefs right now personally, but not getting my hopes up.
