Outside of something transient/bootleg, are there any cases where there was a sustained -NAO while the AO was persistently positive? I would think not, or very rarely.
Yeah this winter the SPV has been a consolidated monster, and it has coupled down to the troposphere. Not much is going to overcome that. Maybe perfect forcing in the Pac that produces a persistent PNA ridge. We would have a fighting chance if that were the case. Not so this winter. Not even close.
For those who were not aware, they certainly should be after this winter. A persistent +AO is death to snow chances in our region.
Only way to somewhat mitigate it is a persistent and strong EPO ridge.
A large portion of the region also had a snowless Jan, aside from a trace.
And outside of NW areas, very little in Dec.
But yeah, it's generally how we roll.
At least the GFS op has teased with a potential hail mary event on recent runs. Yesterday it looked like maybe around the 5th. The 6z run now has one on the 9th. Clipper incoming at hour 384!
Not at all. All guidance has been heading this way for days now. I don't think anyone here is surprised. I just think its fitting if it ends this way. There was really never any tangible reason to believe the pattern would be notably different going forward, outside of shorter wavelengths.
Just to expand the futility area a bit, Philly is at 0.3". Their worst snowfall season was 1972-73, recording a trace.
As of now, this winter would rank second, just ahead of 1997-98, with 0.8".
Just looked at some snow obs for down south. 1-4", with a lone report of 5. Mostly in the 1-3 range. Pretty much as expected, except for those buying into the ridiculous NAM runs.
Decent event for them considering the horrific pattern.
Yawn. This h5 look is as bad as we have seen all winter.
Lets just hope we don't get our seasonal flip to a -NAO until June, where the only damage it can do is make things warmer.
