COLUMBIA — An excessive heat warning for parts of Missouri and Illinois, including Columbia, will be in effect until late Thursday.
Peak heat index values during the afternoon and early evening are expected to climb above 105 degrees and as high as 109 degrees Fahrenheit, according to the National Weather Service of St. Louis. An excessive heat warning is issued by the National Weather Service when high temperature and humidity levels are expected to make it feel like it is 105 degrees or greater.
Actual temperatures will be in the lower- to mid-90s, accompanied by high humidity levels. The warning will remain in effect until 8 p.m. Thursday.
The likelihood of heat-related illnesses increase the longer a dangerous heat wave lasts. Precautions suggested by the National Weather Service include:
- Avoiding poorly-ventilated areas
- Avoiding prolonged work in the sun
- Using air conditioning or keeping your home or apartment well ventilated with fans
- Spending time in an area with working air conditioning to give your body a break from the heat
The National Weather Service advises to not leave children or pets unattended in vehicles, because car interiors can reach lethal temperatures in a matter of minutes.
