I'd imagine that the NWS OKX is going to convert those watches to warnings at least for the southern 1/2 of the counties the northern portion might just be advisories. Gonna cut it really close with the 12Z guidance.

NYC has been under a blizzard warning since 7AM.

If I remember right they did a good job last year in that epic bust.

Yes, I remember the SREFS drop, drop, droping amounts with each run last Jan; and I said the same thing then that we're saying today "SREFS suck, couldn't forecast their way out of a paper bag"

He is referring to the watches in Northern Westchester, Orange, Putnam and into CT....

Sometimes people that live in the city forget that the world exists outside of the five boroughs. 

 

It's getting pretty late in the game for warnings to be issued.

SREFS have been updated since and have done very well with minor events, and rain since

I didn't say NYC I meant the watches that were currently up for LHV and CT under OKXs control. The southern 1/2 of those counties to be converted to warnings and northern 1/2 to advisories.

What times do the RPM models come out?

It runs every 3 hours. As soon as a run is finished to 72 hours the next one starts almost right away. 18Z running now...21Z is next.

I'd probably go 12-18" at this point for the city, points west and Long Island too. Trends so far have all been positive. Isolated 20" where bands can sit around. I think the widespread 20"+ will still be southwest of you, but we'll see how things shape up overnight. Maybe I-84 can catch 3-5" if a band gets lucky enough to reach that far, but it's still looking like a sharp gradient.

Na I am pretty sure that at least Rockland and Northern Westchester and parts of southern CT will be changed to a warning.

hey so you feeling my thinking of 6-12 along the 287 corridor in NY is a good call at this point??

1/21 12z Suite QPF Summary

 

NYC / NJ (i78 - i-195)

 

SREF: 1.50 - 2.20

NAM: 2.95 -3.15

GFS: 1.15 - 2.00

RGEM: 0.55 - 1.40

GEFS: 1.15 - 2.05

GGEM: 1.20 - 2.05

GGEM Ensembles: 1.15 - 2.05

UKMET: 0.80 - 2.15

ECM: 1.15 -  2.150

 

Love this feature you do, thanks!  I modify it a little (I convert to snow in inches at 10:1 and I usually take out the ensembles, as I try to simplify things for non-enthusiasts) and use it in my weather emails and posts on non-weather boards/FB, where I've somehow become a weather source for many.  As I said the other day, I wish we had a pinned thread for just this - actually it would be cool to be able to go to one source for a spreadsheet with QPF/snowfall ranges for each model in each suite and for that spreadsheet to have clickable links to the snowfall/precip maps for each model run.  Maybe when I retire, lol.
