The contiguous United States just recorded its hottest summer (June-August) on record, surpassing even the Dust Bowl era, according to national climate data. In the Knoxville area, temperatures have climbed back into the low-to-mid 90s, prompting local churches such as Vestal United Methodist Church to open as cooling centers, including one running noon-6 p.m. on September 15. Forecasters say the heat will persist with sunny, dry conditions through much of the week and little chance of rain until the weekend. The extended heat has raised health concerns for vulnerable residents, driving community organizations to provide relief options as the region copes with an unusually prolonged hot spell.
