Will use 00z suite and 12z suites to monitor snowfall outputs for Morristown (MMU) posterity and post mortem. Using 10:1 for all for consistency. Yes I realize amounts could be higher/lower due that, but want to have one baseline.  
 

Friday Night - 00z Suite @ 10:1 ratios - MMU

- CMC:  12.9”

- GFS: 0”

- EURO: 17”

- ICON: 0.2”

- UKIE: 6.4”

why the big difference between gfs and euro? why are they showing diffrent solutions? who will win? euro is king no?

This is like Coke vs. Pepsi. These two been going at it for a long time. In a setup like this, I favor the EURO. EURO AI has been great also.

Euro is a crusher.  Euro AI is a whiff.

The GFS will give you insomnia.  Luckily, I go to bed at 10 PM before any of this stuff comes out and read it when I wake up.

I hate the word “tucked”. It implies “tucked in to the coast” which means rain for city and coast. A tucked in solution is bad for much of the forum (not north and west). 
 

a crippling blizzard for the big cities won’t be “tucked” it would be a track inside the benchmark

Wasn't February 1978 tucked in though? I've seen satellite images where it looked like a hurricane with an eye due south of Long Island.  I guess it depends on what type of storm.  Some storms that tuck into the coast are so strong that they wrap cold air all the way around the storm.

The Millenium storm was like that too.

no, just 1-2 feet of snow

Man that 500 is beautiful!  Love the upper low track through northern VA and passing to our south!  Was what I mentioned yesterday morning that would deliver the goods.  Goods = heavy snow, strong winds and very cold high ratio wind driven snow.  
Would love to see these trends continue today or at least something very similar.  Get this to 12Z Monday looking like this and I will feel much more confident.

as of right now the timing for the immediate NYC metro is snow develops sometime after midnight Thursday and tapers off sometime in the mid- late evening Thursday and ends close to midnight so close to a 20 -24 hour event - lets see if there are any timing changes and or duration changes as we get closer and closer to showtime............BTW this is according to the 0Z Euro

it's perfect the heaviest snow will be falling during the day Thursday with temperatures in the 20s and the winds gusting up to 50 mph! On the Euro, the only mixing issues I saw were south of Atlantic City and east of Riverhead. I said *mixing issues* because although it looks like the mix line will get as far north as Toms River and as far west as Fire Island, it doesn't cause lowering of snowfall totals until you're south of Atlantic City or east of Riverhead.

24 hour blizzard Midnight Thursday to Midnight Friday.

Best part is we will finally get a day time blizzard!  This could be the best one here since January 2016.

I'll revise, I think they'll be 12:1 based on past storms like this even with the high winds.  Temperatures will be in the 20s and the snow will be dry and powdery.

 

A blizzard is great I guess with all the high winds and drifting, but not great for snow growth. The high winds breaks down the dendrites. You want calmer winds for maximum snow accumulation potential.

I think January 2016 and January 2018 both had like 11:1 ratios with stronger winds of longer duration.  So, it won't be 15:1 but up to 12:1 is definitely possible.

Be wary of those 06 or 18z EPS jumps.  Seen it before in recent couple of years and then the ensuing main hour run reverts back to what the tendency had been prior.  At least the AI made a jump which is unusual from what I've seen from that model so far

AI isn't in the deadly zone yet.  Euro has been steady with this storm.
