The heat dome has caused significant temperature anomalies across the Central states, with cities like Minneapolis, Chicago, and St. Louis experiencing 5-10°F (3-6°C) above average. Relief is expected for areas like Oklahoma City and northern Arkansas later this week, though humidity may persist. In the East, the warming trend could lead to localized flash flooding as showers and thunderstorms develop along a slow-moving front. Urban areas are particularly at risk for flooding due to heavy rainfall.
