eh...I would even say like lower 90's with mid 60's dews for oppressive or mid 80's with lower 70's dews.
there is no signals screaming sustained "heat". Part of the issue with this trainwreck of a thread is terms are being used that don't have clear-cut definition. There have been no clear-cut signals suggesting sustained heat either...unless you're just rip and reading 180-hr 2M temperature forecasts. Sure...maybe in the medium-range we've seen some signals of ridging well north but once the models correct the idea is tossed away...all you have to do is understand the northern hemispheric circulation...as long as there is that low/trough signals to our north no sustained heat is coming.
In terms of oppressive humidity...not happening. Maybe a day or two hear and there but that is nothing uncommon and does not defined the summer as "oppressive". mT airmasses into our region are common during the summer. We are supposed to have conditons which are more humid than not and periods of oppressive humidity. What is uncommon, however, if to have sustained periods of oppressive humidity...and let's define oppressive as dews > 73F (it seems like the common threshold is 70-73).
Climo now across New England is probably upper 70's to lower 80's for highs and somewhere in the range of 50's for low (mid-to-upper?). In terms of temperatures we've seen nothing special. What has been "special" about this pattern is the frequent rainfall opportunities and anomalous blocking.
