St. Louis, Missouri – The St. Louis metropolitan area is under an Extreme Heat Watch, with dangerous heat indexes expected to climb at or above 105 degrees Fahrenheit each afternoon from Saturday through Tuesday. Overnight lows in the 70s will offer little relief from the prolonged heat.
According to the National Weather Service Saint Louis Missouri, these extreme heat conditions pose significant health risks, particularly during peak afternoon hours. Residents should take precautions to stay safe, including using air conditioning and drinking plenty of water.
The hazardous conditions extend across the greater St. Louis region, impacting communities in both Missouri and Illinois, including St. Charles, St. Louis City, and surrounding counties. High humidity will contribute to the oppressive feel, increasing the risk of heat-related illnesses. Stay in air-conditioned environments, take frequent breaks in the shade if outdoors, and check on vulnerable neighbors. This heat event is similar to the prolonged heat experienced in the region during the summer of 2023.
Possible thunderstorms on Tuesday may bring some early relief from the heat. Until then, officials advise against strenuous outdoor activities during the hottest parts of the day and recommend charging all electronic devices in case of power outages. The Extreme Heat Watch remains in effect through Tuesday.
