The current winter headlines issued by the NWS. Winter storm watches are up for all of CT, with the exception of the shoreline. Why? There is higher confidence of a 6"+ snowfall away from the coast than there is at the coast currently. As we get closer and the uncertainty diminishes, the coast will either see a winter storm watch/warning or winter weather advisory.
The lack of true cold at least initially is due to the lack of a classic block to the north. This can (and likely will) be overcome, but it introduces the risk of northern shifts of the storm track which, you guessed it, put the coast and maybe even southern CT at risk of more rain before a change to snow.
