Hi there! anyone familiar with weather science? Extreme wasn't used before a few years . word that was used was advisory at around 117f. 110f is normal and 113f common. Only 117f or higher use different language I think Danger? Is this due to the drought? Thank you for the help!

I'm just a layman & not sure if this is apropos, but one concept I've learned via climate change in central TX is "wet bulb temperature." This is an intersection of heat & humidity where the body literally can't cool itself by sweating. Maybe "extreme" is flirting w/ that level?

Your body cools itself via sweat evaporation; if the air is hot & already saturated, sweat can't evaporate. At or above the wet bulb temperature, you *will* die being outside, just a question of how long en.wikipedia.org/wiki/Wet-bu…
