St. Louis, MO, August 9, 2026 —
St. Louis is preparing for a significant stretch of extreme heat and humidity, prompting the issuance of “First Alert Weather Days” from Sunday through Wednesday.
During this period, “feels like” temperatures are predicted to soar, reaching between 100°F and 109°F. This combination of high temperatures and humidity poses a health risk, particularly for vulnerable populations.
The intense heat is expected to persist until late Wednesday, when a cold front is forecast to move into the region. This front is anticipated to bring much-needed rain, offering a potential break from the oppressive conditions.
Following the passage of the cold front, a notable shift in weather is expected. Milder temperatures, in the 80s, are forecast for the following weekend, signaling the end of the current extreme heat event.
Residents are advised to take precautions during the “First Alert Weather Days” to stay safe and hydrated in the high temperatures.
