Here is a little weather info I needed to understand better. We are getting that horrible heat that hit Arizona a few days ago and there are differences for us in central Texas due to high humidity and high dew points. Found this helpful info in my search to understand "dew Point" from Wikipedia. Today, at 1pm CST, it is 92 degrees, dew point at 70, humidity at 50%
Warnings are out and it is like walking under water and trying to breathe. Keep cool and safe y'all... From Wikipedia:
When the air temperature is high, the human body uses the evaporation of sweat to cool down, with the cooling effect directly related to how fast the perspiration evaporates. The rate at which perspiration can evaporate depends on how much moisture is in the air and how much moisture the air can hold. If the air is already saturated with moisture, perspiration will not evaporate. The body's thermoregulation will produce perspiration in an effort to keep the body at its normal temperature even when the rate it is producing sweat exceeds the evaporation rate, so one can become coated with sweat on humid days even without generating additional body heat (such as by exercising).
