Again this all depends on what value or cost function the end consumer has. If you're consumer cares about wind speed, insolation, humidity, qpf, or temperature this is a high confidence, low risk forecast. You're assuming that all the consumer values is quantitative snow depth. This imparts a strongly nonlinear cost function.

When the consumer is the public, that's pretty much all that matters. The other 0.25% may care otherwise.

Early thinking from me for central/northern CT was about 4-7'' of snow...not really completely buying a torch BL.  One thing that seems pretty certain is we will have some pretty strong VV's and the winds in the llvls and in the BL quickly wrap around to the ENE/NNE so I don't think we'll have major problems with warm air, with the exception of at the beginning.

We have a 30,000 dollar Frito Lay corporate function with 700 people Sat night at the Museum, what's my confidence risk? If this trends even 2 degrees colder and is amped up, what do I do? Prepping has begun and $21,000 worth of food will be ready at 5pm. People are coming from all across SNE. High risk, huge impact to us forecast

 

If it turns out to be snowy, save some Doritos for me!  :santa:

It's not even that close to a snowstorm at your place...the 12z and 18z GFS have the line for accumulating snow around the MA/CT border, and the 18z NAM has it even further north as the 850-line climbs all the way up to the MA/NH border. I don't see any huge risk or huge impact; this is most likely a 100% rain event for you, and at the best maybe some sloppy snow that doesn't impact road conditions. The dying primary over the Lakes advects too much warm air in for most of us...

 

It's the threats starting around Feb 28/Mar 1 that you should worry about. This one is for the northern crowd.

Euro is what counts, and it has the 0z line in Northern CT after 06z Sunday.

 

Shouldn't be a ton of snow, but not 100% rain.

OKX has other ideas, I know what today's models show, it's not today's that will tell the story Tubes.

Really? I haven't made that many of them...I know I called for 18-24" here in Westchester for Feb 8th, and that did pretty well. I know I also mentioned a long time ago that March might be decent if analogs with fading Niños with like 1978 and 2004 came to fruition. 

 

I am not saying your place won't see snow...but Ginx's work is a warmer climate than Tolland. Also, I think this will be one of those cases where the Euro and GFS compromise on temperature profiles; the GFS will be a bit too warm, the Euro will be a bit too cold, but the Euro will be closer than the GFS. Also, not having the NAM be on the colder side of guidance is worrying if you're hoping for a colder solution. The NAM tends to have a cold bias, especially in SW Flow events, so I tend to think the warmer models may verify when the NAM leans warmer.

OKX's snowfall map looks like crap to be honest. Unless it's back end stuff like the ECM ENS show, there's no way Orange County just 30-40 miles from here is seeing 3-4" of snowfall from this storm. All the models have this being rain, or not a big deal with the late-developing coastal, for the OKX forecast zones. 

 

There's just not a lot going for this event...the high pressure slips offshore allowing for SE winds and fading antecedent cold, the coastal gets cranking late, and the primary tracks well into the Northern Great Lakes and hangs on late into the storm. 

 

Again, I'm not talking about ORH/AFN/BOS/LWM, who could get nailed in this storm. But for NYC metro and most of CT, I think it's time to turn to the next threat.

Well maybe I was  abit harsh, but it seems like you're basing that off of the 18z US models without using anything else.
