Heatwave Alert: Dangerous Temperatures Sweep Across Midwest Cities

The St. Louis area is expected to experience dangerously high temperatures, with daily highs around 100 degrees and heat indexes reaching up to 115, starting on Sunday and lasting throughout the week. This prolonged heatwave may be the first of its kind in nine years. The National Weather Service has issued an excessive heat warning, advising people to stay in air-conditioned rooms, drink plenty of water, apply sunscreen, wear lightweight clothing, and take regular breaks in the shade. The high humidity will provide little relief, with overnight temperatures dropping only to the mid-70s to 80.
