Man, there's a lot to like on the EPS for next week... Even with the big spread in tracks, many of the solutions get it done around here. Weenie maps will be out shortly. 

The clustering is pretty nuts for a 7-8 storm.  Something definitely is happening next week, details TBD.

We need to keep the D8+ deal in perspective a little. We just drilled down to fine details on an op run with more than a week to go. lol. Before we get to that period we still need to get through the current departing storm and 3 additional shortwaves embedded in the flow. The cascading effect of each feature greatly reduces accuracy as time goes on. The only guidance we should drill down with the details are the ensembles. 

Indeed, so to summarize, here's what we DO know:

A. A big kahuna of moisture will likely be coming at us next Tues-Wed, and

B. It will be cold to start

Beyond we just don't know and are gonna have to be patient while all the chaotic activity sorts itself out. That fair to say? Lol

Yea, it looks really good for now. 0z had more bigger hits but 12z just has more hits period. Many of the west tracks/mixed solutions are solid on the front end before ptype problems. Some are snow and sig ice. Not a bad run for a week+ away.

Where is the R/S cutoff?

Yea, there more than just a few but all the big ones are mixed events from what I see. Some of the weaker solutions are able to track underneath. Unless I'm missing something I didn't see any of the larger ones take a good track.

This is a good setup for either a weak wave secs level all snow event or a bigger mixed event.  Hard to get a big event all snow though.  Kinda similar to PD2 setup but even that changed over and it took a perfectly timed/placed Arctic high to even keep it snow that long. VD2007 is a more typical way those end at our latitude if they become too amped up. If you want all snow root for a weaker wave. But there is room for a decent snow followed by big ice solution and that’s fun, especially if we’re protectong our snow pack from back to back weekend hits!

The positve trend the EPS had for snow for the past four days has reversed. 

I don't really think this is exciting , given it is a active 15 day period. But,  maybe the best potential is after Feb 27.  

Certainly the EPS is not as enthusiastic as the GEFS.  I am only using this tool as a guide and not gospel. 

Must be a mixture of events.  As for screwing the mean, I did not look at indivdual members in regards to that.

I know Bob spoke about a mix in the various members, versus all snow in his updates a little while ago.   

Certainly this can, and will change.

If you add 3-10" from CMD on N from today's event it looks pretty similar to the past few runs.  IMO, it's rare to have the EPS show a 6+ mean areawide when there isnt a legit period on the way.

If you just look at the EPS mean through day 8 (midweek storm) looks like the mean is still increasing.  Also, about 60% of the members are showing at least a moderate event (3 or more inches) in my quick count.  (Disclaimer---I am still learning to interpret the ensembles; but it appears that the EPS is showing a much stronger signal for middle of next week than the weekend threat.)

i though the EPS run was a disaster. It never gets an  -NAO. The Pac looks better but its still SE ridge centric but the Atlantic never get close to an -NAO. the D11-15 looks warmer. Not a good run imo...having these anomolies in Late Feb wont work

It's over dude. Almost became a good year but you know how it goes.

somehow we went through another year(Dec-Feb) without a Greenland block lol. I mean...EPS took a step back right?

Depends on how you look at it. Is it showing a big fat red ball -NAO? Nope. Is the h5 mean conducive for snowfall? Yep. Is it slightly warmer than 0z? Yep. Does the Atlantic and confluence to the north look better at the end of the run? Yep. Are there 3 potential snow events in the next 10 days? Yep.

I may be one of the few people in here that doesn't even look at the models beyond 10 days. I just feel like everything is in constant flux and it's pretty much a guarantee things are going to change(sometimes drastically) by the time you get there. To each their own, I appreciate all your analysis. I personally just refuse to do it beyond day 10.

We're all here to discuss winter wx in the winter. D10+ gets a lot of attention for the sole reason that there's often no winter wx to discuss inside of 10 days. Not the case right now but has been for most of winter. If we didn't discuss D10+ this board would be crickets for long stretches of winter. I'd much prefer to discuss a huge D5 storm every single day and ignore everything else but that happens never so here we are.

All it would take is a small se adjustment to all the features and it’s great. I bet with soi mjo favorable we get that adjustment. Look at what happened this week coming up.

It is literally noise. It's a mean @ D10+. There is no significant difference comparing it to the previous run.  Ji is shooketh.

....three systems in the next 6 days have to work through the area before we have real clarity on what is going to happen during the tuesday/wednesday timeframe. Everything is still on the table. The only thing that is probably locked in right now is that there will be a storm. Cutter, coastal, apps runner all on the table imo.
