Now that I am done feeling sorry for myself about tonight this is where my thoughts are on probably our last 2 legit threats this winter.

 

PD3:  I have not given up on this yet.  Looking at what has changed since the models had a more amplified solution, they were keying on the vort diving down the back side of the trough a few days ago.  Since then, they are picking up on the front running vort that comes across the lakes.  They are putting everything into that and squashing everything behind it.  It is very likely that is true, and the first vort is messing everything up and takes just enough energy and pulls the trough east and we are screwed BUT its not set in stone.  I still think that once models resolve the final soution with the first vort, and the energy for the second gets into better sampling areas there is a shot suddenly we see a storm appear again on the progs.  The weak POS thing on the GFS right now is NOT the same storm that we were looking at days ago.  It is the front runner, its the back side energy that could be our storm a day later.  The euro last night was not totally too far away from what we would need.  It was a step in the right direction.  It at least sees the second vort and amplifies it, just too far SE.

 

Feb 22:  This one is really simple.  The trough axis sucks and goes neutral way too early, so it comes down to one factor.  Does the cutter on the 20th become a 50/50 and enforce the -NAO block.  If it does, this is a real threat.  The h5 track sucks, goes to our north, HOWEVER, if you look at the exceptions to the rule on how you can get a significant snow event into the DC area with a H5 track like that, this is it.  WE would not do as well as places to our north...the HUGE snow totals would be PA north, but DC can get a nice thump snow then go to ice/dryslot in this situation.  The 50/50 & -NAO have to be modeled correctly though, and that is also dependent on that lakes cutter bombing out to our northeast.  If, and ONLY if they are right about that evolution, then this is a real threat.

I'm not getting suckered by some 20-22nd deal.

This is how it's gonna go.

168 hours out

Wxusaf says this looks like the best set up in a century

Wes, one of the most respected and listened to mets who will be modest and says he has no skill, will say the ensemble analogs look great!

Ian will post a right on target sarcastic remark and be ridiculed for it.

Ji will say screw PD3, THIS one is it.

Randy will put his chips all in

Bob Chill will focus like a laser and not let this one go.

Zwyts will say all he wants is a car topper and not to expect much more.

120 hours out

Euro doesn't show sh*t, psu will say don't pay attention to the models, the signal is so strong that they will show it

Ji will give up

Ian will post a right on target sarcastic remark and be ridiculed for it.

Wes will say it has a chance, but maybe not

Bob Chill will focus like a laser and not let this one go

Dave will post the UKMET and call condition Alpo

No model will show it, but it'll be close

no way that ULL would go that far north with the blocking. Euro is much more south than this

the atlantic is pretty decent so it might get the old shunt south but we need a lot of work on the gfs.

Funny you said that, I was just thinking it wouldn't take much.  And, for those who like torture, there's another spark later in the run.  Seriously, we are still in a time period where we could rack up some big snow totals in a hurry.  I'm just running out of energy.  Who knows.
