3. After I asked for your locale, I checked your profile and updated my post.

I should have checked first. Duh!

But that's normal? Not the 101 but the 36. I'm in Mass. and it's been a much cooler summer than usual, but we usually have 80s/90s heat and sweaty, sweaty, sweaty high humidity.

4. High heat and high humidity is what we get.

It's all the moisture coming in from the Gulf. Unfortunately it gets too hot to rain, sometimes you can see the rain coming down but it evaporates before it gets to the ground.
And that 80 degrees this morning was with no breeze at all.

6. That's not a big change at all. Dewpoint dropped from 75 to 69.

Relative humidity as a percentage always drops significantly as the temperature heats up.

5. During the same day, the humidity will drop as the temperature rises.

The hotter air has much greater capacity to hold water vapor than the cooler air, and the air will no longer be saturated with moisture.
