It's hard to imagine more than an advisory level  2-4 /3-5 Inch snowfall for much of the  interior.   Far southern interior / south coastal areas could benefit more from the initial waa thump and eastern /southeastern areas could benefit a little bit more if the follow-up wave trends a little bit closer. Perhaps we could see some low-end warning amounts in some of those areas with S and SW Connecticut seeming like the best chance as of now.

This has nothing to do with model performance. It’s not called modelology. If your forecast is based on model read outs rather than an understanding of cloud physics, fluid dynamics and numerical weather prediction comprehension, it’s not a forecast at all. 

I agree with this, models are a tool not meant to be taken as gospel. This is why I ignore those 10:1 ratio maps. I am trying to analyze the dynamics and temp profiles in the upper levels of the atmosphere to make my forecasts, which I wasn’t doing last month, and it did lead to some improvement but I clearly still have a long way to go before becoming a competent forecaster. However there is no excuse for a model to shift 50 miles east in one run this close to the event, especially with the atmospheric drivers in place.

For the most part that is the way it is.  People who have less of a vested interest in a storm tend to pull an Irish exit out of the forum, or at least post less when the trend is not their friend.  With the exception of a few, most of us are guilty of this. 

Hopefully those not invested post less and pull an exit. It makes for better discussion when those who aren't invested or out of it don’t post. Exceptions being people like Brian and Will who always add science in their reasoning

Moosup is almost the bisection point between north and south CT, looking at the eastern part of the state (maybe a hair north of that line).  Definitely not southeast.  

I thought we had a Stonington poster here. 

Closer to Mass by 3 miles than LI sound if it matters at all

Tool is the key word here.

Back to the storm discussion..  I find there are more red flags than green ones  I think QPF output has been too generous.  Mechanics are just not there for widespread 6-8"+

They were yesterday’s runs but those jet dynamics seem to have evaporated into thin air on the newer runs. My interpretation of the atmospheric drivers must have been way off, with other storms I was able to identify where I went wrong but this one I just can’t figure it out.

Like we haven’t seen these things trend north all season? Recall yesterday for example. And the idea the more that wrapped up , the better this next one would be. There’s literally nothing to prevent this from bumping north . The SE ridge always wins

CMC/RGEM had been the most robust with the reinvigoration and CCB portion for eastern SNE... 12z old GFS now on its own.

Still can't completely rule it out, but the trend is not good and we need that well-timed infusion of shortwave energy to reappear.

Otherwise, mechanics are just not there for more than 2-4" north of pike / 3-6" south, spots 7-8" along southcoast, and maybe a little enhancement east.

I’m not as confident as I was 12 hours ago but there is still the possibility that these are just off runs. I’m still going to stick to my guns because we haven’t lost the euro yet and I haven’t seen any huge red flags indicating this south trend isn’t BS in regards to the atmospheric drivers in place. However, I would be lying if I said that this storm isn’t making me question everything I thought I knew about meteorology and forecasting.
