Thanks for posting this. These are interesting to follow.

 -GEFS not surprisingly came in a bit weaker with its amplitude. However, it still remains stronger than Euro/JMA.

-Stark timing differences remain. On March 7th, whereas GEFS is still in phase 5, EPS/JMA are in phases 7/1!

Unfortunately its likely late month when we hit phase 8 and blocking returns due to the wind reversal to muck up spring. 

like clockwork, march gets your hopes up then april crushes us with some of the most depressing weather of the year

I guess it could qualify as a very early final warming since it’s happening in March, but I would defer to @40/70 Benchmark or @so_whats_happening to give a better opinion on that. They are very good with the stratospheric stuff

I guess it will finally 'split' coming up here, I feel a little too late anyway for any big fun but whatever Many have gotten solid snows this year. As far as a final warming it does not completely obliterate the SPV coming up here so technically it is still intact in some way. When you start to lose the idea of any cohesiveness of the SPV then it is considered done which does not look like it through at least mid March. Typically the final warming happens from the last week of March through 3rd week of April but as we know can happen before or after that timeframe.

Sorry been on vacation starting to bring things back to normal for the work week coming up.

Edit: Wanted to add this because this does show the overall structure does split besides one random layer. So this should hit the troposphere rather quick. https://www.stratobserve.com/fcst_ell_vert

There does seem to be some surface connection trying to show up in the longer range when this does occur so I would not be surprised to get a blocky colder pattern as we head to mid month. Ill enjoy the warmth ahead of it though!
