HEAT INDEX
If the thermometer reaching 100 degrees wasn’t bad enough, humidity will remain high over the holiday weekend. Humidity delays our bodies from cooling, so it ends up feeling hotter than it actually is.
Heat index values are forecast to range from 105 to 110 degrees. Here’s a look at the forecast afternoon heat index Monday afternoon:
HEAT SAFETY
While we’re used to hot summers in the Alamo City, this is the first heat wave of the year, so our bodies are not yet acclimated to the triple digits. Take some time to make sure you’re prepared for the heat during outdoor activities this weekend.
