That weenie Wellfleet anny had 70 earlier and it’s at 100ft. The New Shoreham is 144ft on the shore. So if it’s accurate it isn’t exactly representative of the 10m wind.
The wind data at least looks consistent.

Euro kinda has 2 pulses...tonight with better vertical mixing and then Sat night with a stronger LLJ, but more wet/inverted away from the water. But it's still NE 65kt at 925 and 55kt at 950 for Ditty below the inversion.
6z euro has a period there Sat night where 925 gets up to 65-70kt over CT. It’s tough to see on the soundings but it looks like 55kt at 950 over you 6z Sun and the 950-sfc layer is moist adiabatic.
