A late-summer ridge over the central United States is sustaining dangerous heat in the St. Louis forecast area. The National Weather Service forecast on Sept. 2 called for mid- to upper-90s highs and heat-index values generally from 100 to 105 degrees, with some locations above 105. St. Louis reached 100 degrees on Sept. 1, an uncommon September occurrence that did not exceed that date’s 104-degree record. Forecast guidance indicated some modest cooling beginning Sunday, although temperatures would remain hot.

What St. Louis is talking about
Southern Missouri experienced severe flash flooding and storms from July 9-11, 2026, with more than 12 inches of rain reported in some locations. The flooding triggered hundreds of water rescues, including a National Guard helicopter evacuation of children and counselors from Camp Taum Sauk. After joint damage assessments, Missouri sought a federal major-disaster declaration for public infrastructure and emergency-response costs.
Gateway Regional Medical Center in Granite City, Illinois, is facing a potential loss of its Medicare provider agreement after a federal compliance review identified multiple deficiencies. CMS’s enforcement process permits termination when a provider is not in substantial compliance with Medicare participation requirements, though providers may submit corrective plans and seek a resurvey.
Missouri’s HB 3231, the Missouri Innovation, Public Safety and Accountability Act, expands several economic-development incentive programs statewide, including tools intended for downtown and main-street investment. The Department of Economic Development’s MODESA 2.0 program makes state tax-increment-financing support available for qualifying redevelopment projects in St. Louis and Kansas City. A Sept. 2 downtown St. Louis event was described by local and business-group sources as a ceremonial bill-signing celebration for HB 3231 and HB 3080, although the governor’s office records HB 3231 as having been signed into law on July 13.
Automated license-plate-reader systems capture and search vehicle-plate data for law-enforcement investigations, but their use has drawn scrutiny over privacy, data sharing, and misuse. St. Louis County Police Department says it has used its own camera network for more than five years, distinguishing its system from jurisdictions that contract with Flock Safety.
The Missouri Supreme Court heard arguments Sept. 2 in challenges to Secretary of State Denny Hoskins’ decisions rejecting multiple citizen-petition measures from the Nov. 3 ballot. One case concerns the proposed Respect Missouri Voters Amendment 6, which would restrict the General Assembly’s ability to alter voter-approved initiatives and impose an 80% legislative threshold for certain changes. Supporters rallied in Jefferson City while the court considered the appeal.
Missouri voters will decide Amendment 3 at the Nov. 3, 2026 general election. The measure would repeal the reproductive-healthcare-rights amendment approved by voters in 2024 and would allow abortion restrictions, while also addressing minors’ gender-transition procedures. Attorney General Catherine Hanaway’s office aired a statewide women’s-health PSA in August and September that her office says is consumer education; abortion-rights opponents characterize it as publicly funded messaging connected to the ballot campaign.
