You guys think this is bad....look up Feb 1989 lol.  A busted forecast for 8 inches of snow, we got inches of virga instead.

Many on here might be too young to remember March 2001. Models weren't as good as they are now and forecast two days out was for several feet of snow. Ended up with a few inches of mostly slop.

But nothing compares to the January 2015 blizzard. Calls for 2-3 feet the day before the storm hit. 

Forecast:

January 25–28, 2015 Winter Storm/Blizzard - STORM2K

Reality:

Gfs ticking west. This sub forum would be going crazy if it was 10 degrees colder lol

It's similar to the NAM. Puts snow back into the game for NW CT. But it's negligible for the majority of our forum outside of Eastern LI which looks to have quite the wind driven rain event.

Brings the 1.00+ pass you into northwest jersey now.

From Queens/Nassau east I wouldn’t classify that as a miss. Nassau had 12” at the Queens border to 18” at the Suffolk border and 20+ east of Rt 112 just about. Long Beach had 15”. Of course I was living in TX at the time and missed this as well as the monster Jan 2016 storm. :axe:

Okay it was a massive bust for anyone in NJ and the LHV. And it was still a bust for points East of the city when you consider the forecasts.

That was a massive whiff. Jonas followed the year after for us. We got nothing from either storm, and Jonas hurt even more.

 

Latest GFS snows. It's all but certain now where the biggest whack will be

Looking good for High Impact 4+" elevations per NAM and HRRR for a significant impact event e of the CT River interior MA/n CT down to near our just nw of I95...combined wet snow/few wind gusts 35-45 MPH except 50+MPH I95 MA and possibly RI. Hopefully the 12z/4 multimodel westward drift is legit.  IFFFFF it is, I want to point out the HRRR had it first.  I expect gusts 45-55 MPH NJ coast and LI except few gusts lesser 40-45 MPH NYC.

But here in Sullivan County we're watching the trend, another jump west we all go bonkers !

Doesn't look like much more than noise, however, since this run of the GFS looks most like 0z last night. All models probably will soon converge and are doing so already. Next week looks much more tantalizing at this rate.

Suggest looking at Kuchera and merged positive snow depth. Helps with elevations and warm daytime temps. Definitely more favorable than what we saw on the 00z/4 cycle.

Good catch. I expect BOX and GYX will have to issue out Warnings within the next several hours. People might find themselves a little caught out knowing that today isn't exactly cold and that the precipitation is beginning as rain.

Awesome track for many . This could have been a big snowstorm for many on the coast even in the mid Atlantic  but cold air is the issue.

Seems pretty straightforward-cold rainstorm here but colder air and better development by then switches interior New England to snow. CCB develops and pivots east to slam Boston before departing. Guess it’ll be cool to watch and see the New England forum explode but I’m beyond over the lousy windy rainstorms. Maybe we can pull out a miracle with the system behind it which could be a nice event with a little more spacing. Crazy how it’s happening with them in the mid 50s this afternoon.

Noticing two bands of strong banding transitioning northward through CT MA tomorrow...once mid morning and the other early afternoon.  There is going to be quite a power outage event I think in MA/CT high terrain... combo of wet snow and gusts 35-45 MPH... I could see 1-2"/hr snowfall occurrence in parts of N CT interior MA tomorrow.  Big problem up there.  Also... don't give up yet in NNJ and even a snow shower down to NYC-LI in the wake Saturday midday-afternoon.

Thunder I'm pretty sure will happen in southern New England Saturday mid morning-first burst of ice coated snow and strong pressure falls-advection fields. I may add more around 3P.  

I am thankfull this wasn't a big waste of our time...  our CT and even NNJ and se NYS members will see some snow in the air, tho I think the 4+ acsums reserved mostly for CT.  Snow depth on the EC suggests well over 6" in nw CT.  Need to balance this with the still reserved GGEM-RGEM...  marginal thermal profiles.

It's the NAM-EC and even GFS vs the reserved GGEM-RGEM.  What the models giveth, they can taketh.  I don't want to see the 18z or 00z models back down.

 

Here's the SPC HREF snowfall - see it's legend and also the 19z wind gust forecast... (MEAN).

IIRC there was a secondary band that set up over Nassau and far eastern Queens that helped limit the damage in those areas to "regular bust" rather than "historic forecasting disaster" like it was for the rest of the City, NENJ, LHV and western CT. I was living upstate at the time but vividly remember the insane runs and the shock of realizing what was actually happening.

Once the euro was on its own it was clear it was going to bust

I remember before other models started catching on the GGEM was the progressive/east outlier and thinking that was a red flag since it's usually the opposite. Still, the Euro/NAM combo was seen as unbeatable then.

The nam wasn't consistent though. If I recall it had 1 or 2 good runs and then caved to the other models

I thought it was pretty slam-dunk for at least a big time event for NYC with the Euro being so stout. That definitely busted and it started a trend of the Euro being a little too wound up with these storms. It was also a little afterglow for how well it did with Sandy while other models had it going into RI.
