Last few runs of the Euro ens mean shows a bit of a trend towards more east coast ridging at the end of October, as the EPAC ridge is further west and mean trough is in the western/central US. Still eventually gets a trough in the east, but not until the end (of the 0z run), which is early Nov, and it's not a deep trough. GEFS looks similar, but to a lesser degree, and still gets some pretty chilly air here by the very end of the month.. These LR "trends" are what I am keeping an eye on in preseason, because this was the tendency last winter on the guidance- advertise a great h5 look(esp NA block) in the day 10-15 period, but as we get closer to that timeframe, the depicted pattern becomes less favorable/gets pushed back in time. Often it never verified in real time.
I guess going into this winter, I am in 'believe it when I see it mode'. And also, screw the Euro weeklies lol. Have not looked at those once since reactivating WB.
