Midwest & East Coast Heatwave: Summer's Scorching Arrival
Get ready for a summer sizzle! AccuWeather meteorologist Tom Kines confirms this week brings the first true taste of summer heat to the Midwest and East Coast, with temperatures soaring and humidity making it feel even hotter
Summer's scorching arrival: A heat dome will bring dangerously hot temperatures and high humidity to millions this week, making 90°F (30°C) feel like 110°F (43°C). Midwest and East Coast residents brace for extreme heat as AccuWeather meteorologist Tom Kines warns, "Buckle up, because summer is coming!
Heat dome forming
Heat Dome to Bring Dangerous Temperatures and High Humidity Across the US: A large high-pressure system in the upper atmosphere will trap heat and humidity, creating a "heat dome" effect and causing dangerously high temperatures across much of the U.S., according to the National Weather Service. Expect extreme heat and humidity, particularly in the Midwest and East Coast this weekend and into next week
Extreme Heat Wave Sweeping Midwest & East Coast: 90s Fahrenheit (30s Celsius) Daytime Highs, Little Overnight Relief. Expect temperatures in the 90s Fahrenheit (30s Celsius) daily and only dipping to the mid-70s Fahrenheit (mid-20s Celsius) overnight from the Great Lakes to the East Coast through next week
Gulf of Mexico moisture fuels oppressive summer humidity across the US, causing temperatures to feel significantly hotter. This northward flow of moisture is a common occurrence during late spring and summer months
Extreme heatwave grips US: Denver hits 100°F (38°C), Chicago & NYC near 100°F next week. Expect scorching temperatures across the Midwest and East Coast, with Washington D.C. reaching 99°F (37°C) on Tuesday
Midwest Heatwave Warning: Extreme Heat Risk This Weekend. Nebraska and Kansas face a level 4 heat risk Saturday; Iowa, Wisconsin, Missouri, and Illinois on Sunday. Dangerous temperatures necessitate effective cooling and hydration to avoid health risks
Beat the Heat: High Humidity & Extreme Temperatures This Summer
Understanding Heat Index: How Humidity Impacts Temperature
Humidity, the amount of water vapor in the air, significantly impacts how hot it feels. The heat index combines air temperature and humidity to provide a more accurate "feels like" temperature, helping you understand the true impact of summer's sweltering conditions
Beat the Heat: How Humidity Impacts Your Body's Cooling System. High humidity hinders sweat evaporation, reducing the body's natural cooling process. This can be dangerous in hot weather, worsening existing health conditions and potentially leading to heat stroke. Stay safe during heat waves by understanding the effects of humidity on your body's ability to regulate temperature
Beat the Heat: Stay Cool During Extreme Temperatures. Minimize sun exposure, wear loose, light-colored clothing, stay hydrated, and seek air-conditioned spaces for relief from dangerous heat. National Weather Service (NWS) recommendations for extreme heat safety
Phoenix, Arizona's Dry Heat: Why the Desert Swelters Without the Humidity. Unlike humid summer heatwaves impacting the Midwest and East Coast, Phoenix and surrounding desert regions experience intense, yet dry, heat. This is due to their distance from large bodies of water, geographic features blocking moist air, and prevailing weather patterns resulting in minimal precipitation
Dehydration Danger: Why Humidity Impacts Heat Safety. Sweat evaporates more quickly in dry climates, leading to underestimated dehydration, a serious risk highlighted by Johns Hopkins University and Johns Hopkins Health System. Stay safe during this summer's heatwave!
Even the crops “sweat”
In places such as Iowa, crops can affect the humidity in summer months. Plants feel the effects of hot weather and some people in the Midwest are familiar with “ corn sweat,” which is when crops move water to their leaves and other surfaces so it can evaporate, according to the Ohio State University.
Madison County, Iowa, farmer Ryan Marquardt said corn sweat is “not as bad as a sauna, but it definitely would have a sauna effect. It’s humid in there (the cornfield), so you’re gonna sweat.”

Cornfield contributions to the overall humidity are much lower compared to the humidity winds carry from the Gulf, according to OSU.
