I'll sign up for that. Reminds me of those 70's storms where we'd get a front end thump, then flip to rain. Anything that survived froze like a rock as the arctic air poured in on the backside.

That's exactly how it would be a 3 to 8" base of cement with the deep cold following, death race tubing

CMC isn't as far west as the GFS but has the same near-Apps runner concept.  Euro appears to be showing the same although looks further east than the others.  Could be still seeing mid-range noise.  I don't think this will settle down until we get a little closer.

Appreciate the feedback.  I know that physical sampling is less important now, with the reliability and scoring of satellite sampling, but I still hear my old man's voice saying, "look at where the energy came ashore and follow that line of latitude..."

That notion deserves about the same level of merit as "red sky in the morning...," but fundamentals seem to be coming together with this storm.  Going to be a monster, regardless.  Wish we had a true block in place, and confluence set-up from the ocean storm.

Well you have to look at the ENSO states too because the jetstream(s) is(are) what move these systems and the past fall and early winter, the systems have continued to move fairly rapidly (no blocks).  You see front after front just rolling through.  If any of those systems get cut off and stall, that is when you get walloped.

JMA is a mauling fwiw. Damn near perfect track. JV models ftw!

ECM ensemble median track is up I95 this things a commuter..

JMA is a snow bomb off the coast fwiw 

 

The GFS had that hoochie mama days ago, lost her, and is crying in his beer!  :D

Is it normal for DC to get more snow the PHL and NYC in these situations?

I want to say Super Bowl night 2000 DC got slammed and we were rain after a little front end frozen. Don't know that I'd call it "normal" but it's happened.

Classic thump to mix/dryslot for i95 at the very least. Most likely outcome attm. 

There's literally no reason to call that the most likely outcome. So much nonsense Ralph, come on. Outcome could be worse, could be better. It's days away and nothing is consistently dialed in.

with the track as modeled?  yes.  the ocean can do wonders around these parts

Yeah that kind of stings, I kind of want to go out to really far west so everyone gets rain lol. I know that’s silly but a driving rainstorm in the middle of our “epic pattern” is a kick in the nuts.

Thanks Ralph for finally being realistic. I often find you are way too optimistic and not realistic but this is a good start buddy!!!

Which is it? Optimistic or pessimistic? Sounds like you should practice what you preach. Please: 1) quit trolling the forum and 2) post less, read more. Thank you.

And yes, it IS the most likely outcome attm. Almost every red tagger has acknowledged this. Almost every piece of guidance is suggesting this right now. Could it shift? Absolutely. Dependent of wavelength separation, strength of the vort, confluence strength and duration, etc. I agree with that. But seeing this setup several times over the past 25 years of being active in the hobby, this is not a classic clean transfer coastal look NOR a clean Miller A....areas not the way it stands right now on guidance. So I really don't think odds favor an all snow event here attm. I will stick by my thoughts of this being the most likely outcome for now....thump to mix then maybe slot. Hopefully that is optimistic enough for ya. Any snow is good snow I could care less if it taints or flips.

Eta: I would love to discuss offline and spare the members your grief, but your inbox is full, might want to look into that

Thump isn't even looking that hot right now, will need to see some shifts SE to get into the good thump action. As it stands, most of 95 corridor is 1-2 inches, then sleet, then a boatload of rain. N and W of 95 is more in true thumpland right now (3-6") before changeover.

I think the thump will be fine. I do agree that the flip is looking more likely now. Seeing those SE low level winds roaring at tropical storm force wont help those east of the fall line. Again tho, get the sw to phase a little later to allow the low to traverse more longitude before running NNE would be huge in terms of precip types and changeover.

my first call  8-12 in for LV, thunder snow/ sleet maybe mixed in with some frizzle on top as we get dry slotted with wrap around snow of 1-2 in Monday afternoon. Then the 30-40 winds kick in with blowing and drifting roads shut in the open rural areas.  Then the temps fall bigtime .  Then come the parade of alberta clippers afterwards.

Not sure if I want the howling winds and possible power outages followed by a possible epic cold shot. 

 

 

Oh man.... I was literally just mumbling that to myself about 5 minutes ago.  "Power outage storm".  I got one of my sisters a set of 4 portable LED lanterns for Christmas to put around her house because where she lives in Montco, the power lines for her side of the street are strung along a row/stand of woods with a creek in the middle at the other end of the backyard, and the breaking branches take down portions of the lines and/or the transformers, over and over with storms (even with PECO continually pruning around the lines). :axe:

That will not make for fun times truck driving and bulk tanker spring water hauling...

Yes I would love it to be a little weaker as well, let it find that baroclinic zone over the ocean. Seems unlikely at this point but we'll see. I mean even the GFS has it just west of Cape Hatteras before it shows it heading due north.

WU calling for 6" of snow Sunday night. Interesting...

For my area, I'm just taking it (guessing) as a couple inches then some sort of changeover heading into Monday. No shot I'm wasting my time intensely following model after model before later Fri/early Sat...it'll drive one nuts.
