As Wolfie said, last season was a 3rd year Nina. That was characterized by a very strong -PNA (deep troughing out west) and helped overwhelm anything positive we could get from a -NAO. When that -NAO did form, the cold pushed west through Canada and then south into the Plains.
Nino's typically can produce Miller A events (storms originating near the Gulf of Mexico) and moving up the coast. These events can hit New England good, but they can also occlude off the Delmarva and leave us with a banded mess of precip.
They also can form Miller B events (redevelopers off the Mid Atlantic) when the nrn stream of the jet interacts with the subtropical jet. Miller Bs tend to be our bread and butter in New England.
Regardless of the type of storm, Nino's tend to favor coastal storms vs Nina.
Here is a site that lets you compare the 3-month avg of SSTs for Nino 3.4 region ( (5oN-5oS, 120o-170oW)). You can see we are well behind 2015 which is good.
