Of course I worry but we're 96-108 hours out... we are modeled to be grazed and that's kind what the thread P!- headline tried to caution.  

I dont expect a big one here, but I continue 2-6" for the NYC subforum. Maybe I'm too high, but I think being steady with the original perception and cautions is working.

Maybe WPC is too strong too? per it's attached 16z/16 issuance for D5 Thursday, using the legend color bar probs for 3" or more of snow.  

I'll throw in the towel tomorrow afternoon if all the 12z-18z/17 ensembles are less than 1" NYC.  High pressure WAYYYY out west and room to edge north.   

Enjoy what you can in life...

Walt et al - wondering what you think of the latest WPC map on likelihood of achieving warning level snowfall in the next 4 days (30-50% for CNJ/NYC/LI).  I wouldn't think this would be so high, but iirc, WPC goes off the NBM and the NBM at 13Z is way more bullish than I would imagine, even considering it's time lagged (but I can't imagine it's still including very snowy outcomes from 12Z yesterday, can you?).

People forget that Brooklyn on east everyone had 12" or more.

It was only the park that had 6 inches or whatever they had,.

 

SI and NE NJ had smaller amounts too. These types of storms, the bands shift east around Monmouth Co or so, leaving us with lighter precip. Last Feb we finally jackpotted for a change and had nearly a foot IIRC.

It seems like a thread the needle pattern and it's either too far north or too far south. In a season like, say, 2014-15, we would have had snow across a wider range of solutions.

Yeah it goes back to the fact that 2000 through 2018 was like 55 through 69 where we had blocking in the right places and a dominant PNA ridge or EPO.

This probably happened a lot 1970 through 1999 (I know I have stated this at exhaustion LOL).

I remember those two storms and they were pretty decent here too, 4 inches in one and 6 inches in the other at JFK.

The Newark Star Ledger ( I have to mention this at least once a winter ) in 1991 ran a feature on "whatever happened to winter?" Winter started to return in March 92 and went gangbusters in 93 and 94, dialed back to one big storm in 95, and then 96, the gold standard....and nothing again until the New Years storm of 2000-01, and the headlines proclaimed it the biggest snow in 5 years, and it was, about 14 inches.....

Big jump n/w on the ensembles 2 runs in a row 

Patience.  Approaching coastal scraper bomb territory already.  Wouldnt take much more than 75 miles to give everyone their largest totals of the season. 

 

Looking forward to the server getting bogged down tonight or tomorrow morning when the Euro shows something closer to yesterday's early runs.
