Heat Dome Merge Brings Deadly Heat

A massive heat wave is barreling toward millions across the U.S., from the Plains to the Southeast, with heat index values soaring to 100–110°F—and possibly 115°F in the Mississippi Valley. Two heat domes—one over the Southwest, another over the Atlantic—are merging into a giant pressure bubble, trapping sweltering heat and humidity. Cities like Houston, Dallas, Memphis, Chicago, and Pittsburgh will feel stiflingly hot, with record highs likely to fall daily. Even overnight lows will stay dangerously warm. This isn’t a short-lived blast—it’s a prolonged, dangerous heat event demanding caution, hydration, and cool refuge. Support the show:Get a discount at https://solipillow.com/discount/dnn.
