As advertised it has more to do with getting a healthy southern wave to finally eject eastward with a quieter NS. Probably more about improvement out west/shorter wavelengths, and some luck. This hasn't been a typical period of stable, sustained blocking, where it breaks down and we get a big storm. A lot of vorts moving eastward in the NS and flow has remained progressive. That has really been effing our chances.
Still have a -NAO/50-50 on this panel. Nice look if it's real. There is actually another wave behind this one. Yeah its getting awful late though.
