This week, the U.S. will experience a significant heat wave due to a “heat dome,” bringing oppressive temperatures and humidity, particularly affecting areas in Wisconsin and Iowa. Meteorologist Tom Kines of Accuweather notes that this marks the arrival of true summer conditions, with temperatures expected to soar into the 90s°F (30s°C) and high humidity making it feel even hotter.
The phenomenon occurs when high-pressure systems trap heat and moisture, with humidity from the Gulf of Mexico exacerbating the situation. Cities like Denver, Chicago, and Washington, D.C., are predicted to reach extreme temperatures, raising health concerns, particularly in regions rated high in risk for heat exposure.
The article also discusses the physiological impacts of humidity on the body’s ability to cool itself through sweat, alongside advice for coping in the heat, such as staying in air-conditioned areas and hydrating. Additionally, it mentions the role of “corn sweat” in affecting local humidity levels, illustrating how crops can contribute to overall moisture in the environment.
In summary, the combination of high temperatures and humidity poses significant health risks as summer arrives in the U.S.
