High schools in Missouri monitoring extreme heat ahead of football games

As high school football teams are getting ready for Week 1, MSHSAA has guidelines in place for practices and start times. 

Schools use what’s called a wet bulb thermometer which measures heat and humidity, sunlight, and wind speed. 

When the wet bulb pumps out a reading of 92 or higher, MSHSAA recommends schools take action. 

Many games have been moved to 8 p.m. kickoffs.
