I'm getting a bit worried about what the Euro intends to do at about day nine. It might look good on this run, but I bet the trend won't be good. 

man your like a wet blanket today. Lol. Don't take that the wrong way love and highly respect your analysis. Gives me pause that maybe I'm just allowing my early season holiday upbeat mood to effect my opinion but it's obvious you really don't like the pattern either medium range or long term. Curious what's your thoughts on the winter as a whole right now if you don't mind sharing.

Don't think anyone's going to be upset at this Euro run.  

I certainly would be if the Euro was right with the ptype with the second wave.  The western and northern folks would do good but us easterners would have to get our snow with the weak overruning from the 1st wave.  Of course, all will be different the next run but.....I'd prefer a more suppressed look even if it gave less precipitation

It's a much more dynamic event then before so we're still talking more complicated but this setup ups the ante for sure. Good h5 track and goes neutral at a good point. H85 passes a bit too close to keep all snow along 95 but please don't waste a lot of time on that. It's 8 days away and honestly how many big storms are 100% snow anyways. That's like chasing the white elk. If the urban corridor gets 8-10" then mixes with sleet are we complaining?

I'm almost 100% sure euro ens will add nothing except more uncertainty to the discussion.

No complaints here. Seems like both the GFS and the EURO have decided at 12z that this event will be more dynamic regardless of p-type.

no complaints here Still not jumping on any op though - euro ensemble should be telling. My expectations are just to get on the board in 2017 whether we taint or not.

We still have a decent shot to see accumulating snow in the next 2 weeks. That should be the main focus for now.  Back to chopping down trees. I'll pop in for the EPS later.

Well hopefully halts all the cliff jumping from a single GFS op run 7-8 days out. 

There's going to be a storm next Friday-Saturday.  Long wave pattern is fairly favorable for us.  Not much else to say yet.  

Yep.  Said almost exactly what you said in that last sentence yesterday.  There's going to be a storm.

I hope everyone remembers that the euro is the king of fantasy snow.

So, at least based on the low resolution maps I'm looking at, it would appear that the Euro takes a little bit of sheared out energy, along with some baroclinicity and gives us a tiny bit of precipitation early Friday.

Now at 12Z Friday, the Euro has a fairly impressive s/w out in southern Nevada. The GFS at the same time, however, has that same vort apparently over northern Texas and its beginning to interact with a s/w up over souther MN. The result is, well, the result we see on the GFS. So, let's discard the GFS and go back to the Euro...

The Euro tracks its "trailing s/w" across northern Texas and into Arkansas by 12Z Saturday and into western Kentucky by 18Z and western WVA by 0Z Sunday. At that point in time, even before then, it was dangerously close to having taking the trof negative, but it didn't quite. Had it done so then that's more often, than not, a decent way of getting a bit (couple to a few tenths) of over-running perception before redevelopment takes place off the VA Capes and NE Md through NE get hammered, but that's not what the Euro does so let's just focus on how the Euro does what it does... 

The Euro is much stronger with that piece of energy that'd dropped down from the northern stream and into NV earlier in the forecast. Much stronger that is compared to its 0Z run. Not only that, but it's considerably stronger with the next piece of energy dropping down off the Washington coast at 12Z Saturday. The Western ridge orientation isn't exactly spectacular for Saturday to begin with (quite flat and along the west coast rater than inland a bit). I'm worried that the Euro is already on the cusp of deepening Saturday's system "too fast" (for our happiness) as it tracks into MS/AL, that, I think, is a byproduct of the "barely acceptable" western ridge. Now, take that feature dropping down along the WA coast and follow it along its trend for the last 24-hours and you have a recipe for a sharper west coast oriented ridging. That then is a recipe for our thread-the-needle, marginal thermal profile, to end up tracking well west of us, up into the OV, before redevelopment off the Delmarva.

It'll show two or three camps of solutions. So, yeah. Meanwhile it's blizzarding again outside. My yard is still covered and white from this morning's nearly half inch. At this rate, and with considerable luck, I could approach an inch for the day.

Does anybody know if the Euro upgrades fixed it's known bias to hold energy back in the SW? Or is it doing the same thing it has always done?

It doesn't appear to be holding much back on this run. As to your question, I believe they flagged the tendency to hold energy back across the four corners region and/or off the Southern California, Baja coasts. I think they also did something to address the euro's tendency to go ballistic off the SE to MA coast in the transitionary months (e.g. The tendency for explosive cyclogensis, and cutoff in March and November).

It has had some instances of over amplification in the med range this year. That's probably the only thing I've noticed so far this winter.
