Outside of that we have had offshore coastal lows produce big snow for southern/eastern areas when we have had a mechanism for legit cold(-EPO/PNA) and complete absence of SE ridge. Might be a new normal or base state embedded in there somewhere.
Plenty of spread among the EPS members on low location for the 11-12th period. Not the strongest signal I have ever seen for a favorable MA coastal low track. Best signal for frozen in this window is to our north, again. Still time.
The best signal for a storm with some frozen in our area on the 0z ens runs is March 11-13 period. Fairly weak signal overall, but it's there. Strongest on the GEPS.
I keep it simple. The atmospheric longwave pattern is made up of ridges and troughs, the existence of which serve to maintain heat balance and conservation of absolute vorticity. The phase of the pattern will shift(and change the relative location of the troughs and ridges) largely due to drivers such as ENSO. At this point I still think the SE ridge is largely an effect- in this case the downstream result of a persistent upstream Aleutian ridge/-PNA blocking pattern in the Pacific. There are possibly other influences that contribute to the seemingly 'easy development' and persistence of the SER in recent winters. Not to be discussed in this here thread though.
We really need the Euro's superior resolution/computing power/diverse array of data assimilation, or whatever the fuck supposedly makes it better, to be right in this case. Not that the GFS is awful, but we don't have a lot of time here.
I mean, its not impossible. As I have said, give me one solid 6" snow event that sticks around for a day and I'll be content after this disaster of a winter.
