Looking at this 12z operational GFS version ... there's likely to be a very significant acceleration of winds pushing W into coastal Mass/Cape and the Island between 00z and 06z, tonight.

That's the critical window for the loftiest gust numbers ... but some considerable roaring over roof tops as it tapers only slowly through mid morning ..By mid day, tomorrow ... the wind will likely relax rather abruptly to just breezy with a few minoring gusts, as the low pivots quickly away as is weakening while doing so.

My guess for max gust will be 84mph, with mid 70s over the exposed arm of the Cape and the Islands, ..with the highest numbers for Boston being mid 60s.   Tapering off by wind climo heading west.   I think NW of a PSM-PVD axis ...despite the gradient, much of the wind will be confined to the fast motion of the clouds with just occasional tree leans.

That'd be my wind anatomy based upon this GFS run.

Are you thinking the 60-70mph gusts forecasts for BDL are overdone?
