Pattern Fabulous February

gfs starts to break down ser by hour 240, I don’t know or think it will completely collapse, in fact I think it may strengthen again
 
Lol everyone focusing on the old Gfs when it is barely a model anymore. Gfs is a crap model. Fv3 should be the only model looked at when looking at an actual American global model. And the new Fv3 still shows significant ice storm for the CAD regions basically all of NC at hour 200

Is that what the 18z Fv3 is it back to showing CAD Storm?

I’m all in . Winter sucked , everyone was wrong . Yes we’ve all had good snows late February into March . We’ve been kicking the can all winter. The seasonal models were wrong , the weeklies suck and I’m over it . Bring on tornadoes and hail

We'll score now!
 
Anyways it’s still 200+ Hours, Not really thinking/worried about it since it’s 7+ days
 
Lots of hints of blocking showing up in the LR. It fits with how this winter should evolve, so I give it credibility. Just gotta get that PNA to respond. I still think it will. My guess is that within a couple days either side of 2/15, we’ll either be in or transitioning to a +PNA/-NAO regime or on the cusp of doing so.

Thanks for not throwing "sun angle" in there ... ;)

So in other words, just in time for March.
 
This looks awfully familiar...

Aside from the local sensible impacts here, the bigger picture is what a pattern like this does globally in the longer run say like several months to perhaps even a year from now as far as setting a few key pieces of the puzzle that have some sway in the winter of 2019-20.

Mid-late winter -NPOs (North Pacific Oscillation) fuels positive Pacific Meridional Mode (+PMM) events in the spring that ultimately provides a boost to El Nino during the spring predictability barrier and is favorable modoki/CP ENSO and El Nino in general at least until we're deep into the summer anyways because there's some seasonality in the ENSO-PMM relationship. Given we already have set the table for a NINO as is holistically, and we're reinforcing what's already a pretty decent downwelling Kelvin Wave in the central Pacific as subseasonal forcing persists in the Pacific, I'd lean towards another +ENSO winter next year, and go insofar as to say we'll probably find ourselves contending with a legitimate El Nino in 2019-20.
