Feels LikeWarm and Close

The air feels very moist and my skin is clammy. The pages of my book are warping from the moisture they are absorbing.
I had to wair a good while for a break in the clouds to pass in front of the Sun to be able to make an observation. The various densities of swirling cloud looked interesting passing in front of the Sun.
Most of the clouds dissipated down to scattered clouds after I had made my observation and was sitting there reading. The humidity seemed to decrease also and I don’t know whether to attribute that to a frontal passage or if it was just a perception thing with me sitting there in the bright, hot Sun.
