Totally not being a di**, I know it's exciting, but let's keep the banter to a minimum, so the people that log on in the AM can get good information on the 00z runs if they missed it, without sifting through discussion... (not anyone in particular) just a statement 


Being one of those posters. Thank you

Some areas will likely dry slot rather then changeover. I think in fact that most here probably do. That SLP track hugging the NJ coast has dry slot written all over it unless it kicks way East from there.

The 700mb low track is the best way to find the dryslot. If it goes west of you, you'll likely be in the dryslot.

This looks like it could go down as one of our truly great late season blizzards with the JP zones going 20"+ and wind gusts in excess of 50 and 60 mph in spots. It will be difficult to measure since there will be so much drifting. This was the one type of extreme 2000's snow event that we have been missing until now. Late season has been the most elusive with many disappointments like March 2001 and the blizzard just missing to our SE last March 3rd.

Very impressive maps.

Doing quick snow math in my area.

2.0 of QPF using 1.3 to 1.5 snow math ratio = 26 - 30 inches of snow

Bottom line, a slow moving nor easter with copious Atlantic moisture and a large precipitation field extending far north and west.  Is this a Miller A? 

No it's a Miller B. The SLP is a direct redevelopment of the Northern stream energy associated with the ULL. It's not a perfect example as a Southern stream vort is also involved.

...being on ELI do you think we stay all snow OR does ELI mix or change to rain?

gonna be a close call..

I don't think mixing in eastern areas is out of the question. 

I think once to 48 hours , that gets resolved.

Next start to look up for a tick up in QPF.

I think this ends up being a  2.5 to 3 inches of liquid event on the coast and 2 inches for most on the board.

 

A great March Blizzard is on the way.

Curious to know why you think there will be an uptick in qpf

I think by 00z tonight models will start to blend in well... the southern stream is being sampled today by NHC, so better data should be available

They're all blending pretty well for being 72 hours out. The next 24 hours is when we typically see one of the models do something screwy and then have to figure out if it's a trend or not

Higher resolution models start to see banding .

The UKMET deepens this system 29 mb in 24 hours as it deepeing to our latitude so there's tremendous frontogenesis here .

Mature systems like this usually dial it up as we get closer.

 

This should also CCB so this has a chance to be a 24 hour system and not your typical 12 to 18 hour progressive NE snowstorm. 

We will see.

Thank you!  That was quite educational.

Hurricane force wind warnings may be possible just offshore.


In regards to the forecast gradients associated
with this system, the 06Z GFS by forecasting an associated 60-80
kt 925 mb jet to develop immediately N and NW of its forecast low
hints at the potential for hurricance force winds developing Tue
morning/early afternoon offshore New Jersey and Long Island. The
previous forecast package used the 00Z ECMWF boundary layer winds
for this system, boosted up approximately 15 percent to account
for the models low bias, which resulted in max winds up to 55 kt.
So for now with the event still three days away and with the
latest models still having some differences, will continue to use
these ECMWF winds with only some minor additional edits in 
deference to the 00Z/06Z GFS and then will see later if the 12Z 
models dictate adjusting the winds higher.

 

Chris , yesterdays 12z Euro had 84 mph gusts out onto ELI with 55 mph sustained winds along the NJ shore.

 

I think those type of winds are possible here
