Folks,

 

The 12Z ECMWF is now doing exactly what the conceptual model would suggest, and what we said a few days ago, with the antecedent arctic airmass.  No way would a surface low track due E through the OH Vly through the Appalachians and into the mid Atlantic like the GFS would suggest.  The EC now shows a more typical Miller B setup with the surface low from BNA to the coastal front near CAE/CHS...then NE crossing the NC outer banks.  

 

Game on! :)

The surface isn't a bad match but the 500 pattern looks quite a bit different.

yeah...I just made it up off the top of my head as a quasi-joke because it gave us a lot of snow during the day in cold air with an OV low

 

 

This is a pretty sweet snowstorm pattern

I was going for that because of the low moving up out of the OV as well, and the satellite images are interesting, think we could see that coming up as well. I love some daytime heavy snow, hope we get a lot of daytime into some nighttime, wanna remember both heavy snow at day and night, snowed hard during 12/26 last month but only for an hour in there with mdt snow the rest of the time.

I had something out of the office at 12:30  and just walked back in

I need to stay away for all the Euro runs

it doesn't get any better than this for us

 

It actually can....get a little more spin in the upper levels and we can get a solid 3-6" waa and another 2-4" from the deform on the back of the comma. Plenty of runs to go...

And that in addition to the rumored ratios everyone was talking about a few days ago haha, but seriously thicknesses do support healthy ratios.

I usually don't like seeing a vortex over BC, but it actually helps pump heights over Baffin Island....The most likely piece to be wrong because it is a euro bias is  that trough off southern CA, which if it wasn't there would probably suppress the storm even more which may or may not help us...

euro looks quite a bit better than GFS at the same time, especially with heights rising east of that vortex off the west coast...perhaps the reason for the better solution?

 

I think that is much of the reason.  Allows for more downstream digging.  Alos, I think the euro was a little stronger with the Thursday clipper event which also helps with more cold air and some confluence across new england.

Post that same map from a month ago..... I bet you don't mind seeing the vortex after that.

I've been joking around more than usual today but I do agree about the clipper holding a big piece of the puzzle. I suppose hedging that it ends up being a bit stronger is not unreasonable. Especially once it spends some time over the atlantic. The gfs solution is fine too but there are definitely enough hints being dropped that a more southern track on fri isn't just a fantasy.

nobody is being picky...it is a great snow pattern with cold air in place...I just want liquid...i really dont care about anything else...the chances of a driving rainstorm even with an awful track is pretty low...we'd still get frozen on the front end

this storm is really moving along; we might get a little better qpf totals out of it, but not much in light of its projected path and speed

just freeze it here anyway

I think QPF maxes around .75 could work, and there will as always be heavier rates in some bands that will bring down more totals anywhere heavy snow occurs. Ratios would be good, but as I said, I'm not going there until we have nailed down a track.

Sorry if it came off that way, was not insinuating that.  I agree, thats why I've been rooting for wet/warm runs over dry/cold ones.

Another thing to note is that we'd have "stickage" on all surfaces right from the get go and if the Euro solution is what other models come to, the salt on the roads wouldn't really do much, just a note if colder outcomes prevail. 

A lot of jurisdictions are using combinations of chemicals now that work to much lower temperatures.

there isnt a breathing soul who likes winter who wouldnt lock in the 12z euro as is.....0.6" liquid into a massive cold dome....I dont know if there is an unstable layer or if snow growth is  ideal but low viz +SN during the day is likely.....can you imagine getting raked by fat dendrites at 20 degrees at 4pm on Friday with 0.25mi viz?....of course it probably wont be best case scenario, but we can dream...
