Cape Girardeau, Mo. – Triple-digit heat is currently gripping the Missouri-Illinois border, with heat index values reaching as high as 106°F through Friday evening. This extreme heat has prompted an urgent Heat Advisory for millions of people across the region.
According to the National Weather Service in Paducah, the Heat Advisory remains in effect until 7 p.m. CDT Friday for areas including southeast Missouri, southern Illinois, southwest Indiana, and western Kentucky.
Cities such as Cape Girardeau, Carbondale, Paducah, and Evansville are experiencing the first prolonged stretch of heat and humidity this summer, which increases the risk of heat-related illnesses.
Affected Areas and Heat Index Values

Health Risks and Precautions
Health officials warn that the effects of heat stress will compound each day of exposure, making it critical to take necessary precautions. Individuals are advised to:
Wear light clothing to stay cooler.
Avoid direct sunlight during midday when the heat is most intense.
Seek air-conditioned spaces whenever possible to reduce the risk of heat exhaustion or heat stroke.
Heat Advisory Extensions and Updates
The Heat Advisory may be extended into the weekend if dangerously high temperatures persist. Emergency managers emphasize the importance of staying updated on local emergency alerts and preparing for possible additional heat-related advisories.
