A heat dome will bring scorching temperatures and high humidity to much of the U.S. this week, especially the Midwest and East Coast. Forecasters warn of extreme heat impacts, with temperatures in the 90s Fahrenheit (30s Celsius) and heat indices potentially 20 degrees higher. The heat wave, fueled by Gulf moisture, is expected to last into next week, with cities like Denver, Chicago, Washington D.C., and New York City facing dangerously high temperatures. The combination of heat and humidity makes it difficult for the body to cool down, posing health risks, especially for those without access to effective cooling or hydration. Experts advise minimizing sun exposure, staying hydrated, and seeking air-conditioned spaces.
