Can you explain this map to a novice?

 

The black contours are the mean heights, an average of all the ensemble members (SREF is an ensemble)....the color fill represents the spread among the solutions..those blues indicate there is a lot of spread and divergent solutions among the ensemble members, so the mean is less reliable..

I'm a novice as well but I'll try!  Ian/Wes/etc feel free to interject and correct me.  This shows the 500 mb heights and vort.  I like to use this map as a sort of 'highway' for the storm, especially in this type of set up (Miller A).  The trough (dip in the lines) is starting to go negative (its not quite negative yet at 87 hours) which hopefully will capture the surface low and bring it up the coast. 

 

Since the SREFs are a combination of 21 or so members, this map also shows the mean with the spread (fill colors).

Hey guys, lets keep this thread on topic... model discussion only from here on out... cut the weenie crap to the banter thread.

Yeah, what this moderator said!

 

Seriously....it's time to move from less banter to more storm talk.  Banter is fine early on, but we're starting to hone in on the storm guys.

I like EPS acronym for euro and gefs for gfs. Don't want to confuse tho. Maybe call it EEM? Euro ens mean is cumbersome imo

Given they come out at different times it probably doesn't matter.

 

It would be interesting if this happens as Euro ens is a classic 95 snowstorm.. missing for a while but a few (lesser) this winter now.

 

We just need to fill in the 8-12 through DC and Philly now.

it's basically a west-leaning classic track for us...deepening low moving from Mobile to Savannah to Hatteras to just inside the Benchmark..

what did we do to deserve this?...never mind

that SREF mean is pretty d@mn incredible regardless of how lousy the SREFs can be

however, taken in light of all the other model (and their ensembles) guidance to this point, save the GFS, this thing is shaping up the way the big ones do once you get around the magic 72 hrs.

I'm not saying it's gunna' be, but it's about the best looking system with substantial guidance and ensemble support at this range since a while, and I'll leave the one I'm thinking about out of the discussion for now

Wow- EPS is one b'dass look. A bit east. I've been out all day and just started catching up. This thread is a mess. I vote for analysis only from here on.

Didn't there used to be a "storm mode"? If there is a time for it to be reinstated, it is now. Of course that means I'll have to shut up but, hey, better for everyone!

on a related note, we might get a little help from those below normal SST right off the Atlantic coast by 1) less warmth to be brought into the system, and 2) likelihood that the slp would seek the best baroclinic zone which would be on the eastern edge of the below normal temps I would think
