Mid/Late February will be rocking. (This year we mean it!) February long range discussion.

after our initial major blocking spell, it wouldn't surprise me in the least if we ran it back. the ECMWF has moved strongly towards another SSW that would quickly couple looking at NAM

That's a big change in 5 days!  Strong El Nino/-QBO has a very high correlation with Stratosphere warming, so I was actually surprised when models were showing a strong 10mb PV end to the year (the historical percentage is about 75-80% for the DJFM to have 10mb warming/cooling when the two indexes are together and strong)

the weeklies are absolutely ridiculous. there are too many frames by themselves that are pure weenie fuel

here is just the 25th by itself

I wonder if the block will stop when the SOI moderates (It's in the -30's/-40's now). The subsurface ENSO has neutralized, and I found, all things neutral, for that to be the biggest correlator to the pattern.. even a negative tendency now in the subsurface, so I would guess this favorable pattern lasts as long as we can keep the SOI negative.

XXX Porn.  Might really be the best weeklies ever, I mean ever.  March might set snowfall records in the Mid Atlantic.

I remember a March many years ago when we had snow every week in March. Does anyone remember the year?

I’ll be following for the VDay event, but we need the stars to align. Not out of the realm of possibility for sure, but thermals will be a problem. Just no significant cold air to work with. 
 

The pattern afterwards though :ph34r:

It is a literal thread the needle with wave timing. We need one piece of NS energy scooting out in front phasing into the 50-50 low to flatten the flow up top, then the southern shortwave to move east just behind, and then to keep it from sliding harmlessly eastward off the coast to our south we need the next piece of NS energy to capture it just as it approaches the coast to induce a strong low just to our southeast with plenty of lift/ dynamical cooling, but not a full phase and not too soon..

Even great patterns require a dash of luck....hopeful it will happen, but it is not a lock until we have a threat inside a few days.

But why post one member from an ensemble?  From last night’s run?  Seems like deliberate debbing man

So basically...like the Ghostbusters car...it needs everything!
