Interested to see how it pans out. Usually when you have a storm that can last over multiple tide cycles is when we have our biggest issues on the South Shore. Looking at it for Scituate you have tides of
9.8 Friday PM
9.7 Saturday PM
9.8 Sunday PM
10.0 Monday PM
If the winds are more out of the ENE then that is when historically the flooding has been more significant specifically in Scituate. Not to say that NE is a cake walk but the more northerly component there is it is more like a big bowl of jello sloshing around.
