February 2013 mid-long range disco thread

There's a lot of similarities on the setup of the Feb 13 event to the current one.  Notice the northern stream piece on the Euro (Day 4 500MB map) that the Euro resolves on its 12Z run by squishing down the southern stream energy vs. phasing it up, hence its OTS.

 

The 18Z GFS doesn't have that pronounced feature letting the southern energy wrap up by itself and hug the coast. 

 

It was in the day 3-4 range guidance started to resolve the vort interactions with the current event...which ended up being a full phase and a bomb to our NE.

 

All we need is good inteactions with these features in the TN/lower OV valley and we are set.  I'm not as worried about rain as I am a miss, given that the 528dm line doesn't clear northern Maine (and hasn't on recent GFS runs)  by time the vorts in question get to the longitude of the Great Lakes.  Those heights are favorable to keep enough cold air in.

 

That being said, I think the Presendent's day setup has pretty darn good potential as well and might be the best out of the two...hasn't it been a while since we had a "true" Miller A around here?  Maybe Feb 2006?

Damn, sounds like a one in a thousand year week or two around here. Guess I better oil up the shovel and plow.

One good thing, it's not a million years into the future.

I don't think this upcoming week will be even 1% as good as the stretch in early February 2010. If we get 4 inches total it will be a victory. This winter is just awful.

I think you are absolutely correct. At this point even my optimism has suffered a standing 8 count.

I'll be recovered in time though.

Does a storm 10 days away look this good or is everyone just trying to avoid watching New England get buried?

the first event looks interesting.. the second one is total fantasy still and looks weird.

I hope at least one of these works out.  It's too early to tell and quite honestly I don't even want to look at the models until Tuesday (for the Wednesday "event").  I'm not a sophisticated enough forecaster to say for sure, but I would think a -NAO and a pumping STJ give us a chance.  Sounds more like an El Nino winter, to me, but because it's not I have a healthy dose of cautiousness.

one thing is certain. It's not looking like this in 192 hours.

 

 

 

The entire evolution is weird. But it's been weird in back to back runs. I guess it's possible for an upper level trough to dig full conus latitude vertically while not moving horizontally. but I have a doubt or 90.

this run looks better/more believable than 12z. with the 12z 500 low closing so far west and being so far north not sure how we'd get a good snow.. not to mention the storm forming near the coast and heading for the lakes.
