I think if you are 5-10 miles north of the CT Coast, no need to worry. Unless there are more ML moves north or the system decides to "attenuate". I live on the coast of CT so my posts my seem alarmist lol. I know how it rolls NOM (north of merritt).
I'd roll the dice with the precip rates. Run SKEW-T's at your location for temps but this looks like humongous dendrites for a few hours probably accumulating on the typical colder surfaces and ground. I am talking Merritt south in SCT only.
