Midwest and Gulf Coast Brace for Dangerous Heat Wave Next Week

A high‑pressure ridge is set to dominate much of the United States early next week, driving temperatures into the upper 80s to low 90s Fahrenheit across the Midwest, including Minnesota and Wisconsin, and the Gulf Coast. Heat‑index values are expected to reach 95‑108 °F in the Midwest and 108‑112 °F along the Gulf Coast, prompting heat‑advisories and possible extreme‑heat warnings. Minnesota’s Weather Authority has issued a Forecast First Alert, labeling much of the state a “major” heat‑risk zone, with severe health threats such as heat exhaustion and stroke for vulnerable populations. On the Gulf Coast, a Saharan dust plume will raise heat indices further and may degrade air quality for those with breathing sensitivities.

Local forecasts vary: West Virginia experienced a calm day after heavy rain, but flash‑flooding remains possible through the weekend. Boston and New England anticipate a stretch of sunny, mild weather with only occasional showers. The Midwest’s Northland region expects hot, humid days and scattered thunderstorms from Monday through Thursday, while isolated showers are possible in the Arrowhead and northern Wisconsin.

Overall, the combination of high temperatures, elevated humidity, and lingering moisture from recent rains creates a dangerous heat wave that could affect health systems, outdoor workers, and infrastructure across a broad swath of the United States.
