Heat Dome Traps Central US, Millions Under Extreme‑Heat Alerts
A persistent high‑pressure heat dome is covering much of the central United States, keeping temperatures above 100 °F from Dallas to North Dakota and driving heat‑index values as high as 114 °F in central Kansas and 113 °F in Mason City, Iowa. The dome is expected to affect roughly 70 million people, with heat advisories spanning from the Gulf Coast through the Midwest to the Great Plains. In the Southwest, temperatures could climb toward 120 °F. High humidity prevents night‑time cooling, heightening the risk of heat‑related illness for children, the elderly and people with medical conditions. An Extreme Heat Warning remains in effect for Kansas through 9 p.m. CDT on Monday, July 27, and a Heat Advisory follows through Monday night. Forecasts indicate the heat will persist through the week, with only possible relief by the following weekend. In addition to the heat, the National Weather Service warns of severe thunderstorm potential overnight in northern Minnesota, Wisconsin and north‑central Iowa, with the main hazards being damaging wind gusts and large hail. Authorities advise staying hydrated, using cooling centers, limiting outdoor activity during peak heat and monitoring local alerts for both heat and storm threats.
