I can’t speak for others, but I don’t think the goal posts have substantively changed, at least in terms of my expectations.
A quick flip is always nice, but it was flagged weeks ago that there was a significant likelihood that a change in sensible weather for most would lag the upper level changes. Will has consistently talked about the pattern change occurring in stages.
Obviously, we’d like to see op runs and ensembles aligned especially with regard to the PAC, but as @40/70 Benchmark and others have noted the overarching change is rooted in tropical forcing and is unlikely to totally flop.
I will readily admit to having no proficiency in that kind of analysis but just looking at the 500mb evolution I think there’s a lot of consternation over the speed of the sensible wx change when there’s not a clear trend imho that has raised alarms that the post 15th period will be “bad”.
I still think we’re moving in the right direction, with a potential window for a mixed bag (advisory) system between the 10-15th and higher end potential (warning level) after that.
