US · Published Jul 24, 2026
A sprawling heat dome is set to expand across the central and western United States this weekend, bringing dangerously high temperatures to millions.
According to AccuWeather, temperatures near or above 100°F (37.8°C) are expected across much of the Dakotas, with even higher values forecast for parts of California, Arizona, and the desert Southwest.

Impact & Risks

The extreme heat poses significant risks to public health, particularly for vulnerable groups such as older adults, children, and outdoor workers. Heat-related illnesses like dehydration, heat exhaustion, and heat stroke are major concerns. Additionally, the heat wave could strain electrical grids as air-conditioning demand spikes, potentially leading to power outages. Agricultural stress is also anticipated in areas experiencing declining soil moisture, which could impact crop yields in the Plains and Midwest.
