Over the coming week, about 70% of the US population will experience temperatures in the 90s, and nearly 20% of the country’s residents will experience temperatures above 100 degrees. Many major metropolitan areas including Minneapolis, Chicago, Nashville, Memphis, Dallas, New Orleans and Atlanta can experience temperatures near or above 100.
More than 100 high temperature records could be broken this week, mostly in southern and eastern parts of the United States.
In Minnesota, where cities like St. Paul and Minneapolis are under extreme heat warnings, roads are already beginning to warp in the heat, including two in the Minneapolis area, UKTN affiliate KARE reported.
Many regions expected to set records were also hit by extreme heat last week when a massive heat dome brought triple-digit temperatures to the eastern US and Midwestern states, beating daily records in several cities.
Last weekend saw several new daily high temperature records, including New Orleans, which hit a high of 97 degrees, and Mobile, Alabama, which surpassed its 1913 record by 100 degrees when it reached 101 degrees on Saturday.
As of Monday morning, more than nine million people were under heat alert in eight states in the northern and central United States, including Minnesota, Iowa, North Dakota, South Dakota, Michigan, Wisconsin, Nebraska and Kansas.
But that number is expected to rise throughout the week as heat continues to build across the Northern Plains, Midwest and Gulf Coast on Monday, potentially bringing triple-digit temperature records as it progresses. in the Southeast and Mid Atlantic on Tuesday.
Electricity providers in the southeast told UKTN they were ready for the second heat wave in a week.

Many communities battling the heat might not get much relief at night either, as 100 overnight low temperature records are expected to be broken throughout the week.
The lingering heat follows a week in which extreme weather conditions hit millions of people across the United States. In addition to the massive heat dome, historic flooding inundated Yellowstone National Park and its surrounding communities, wildfires erupted in Arizona and New Mexico, and severe storms in the upper Midwest and the River Valley. Ohio caused widespread power outages.
Hundreds of thousands of people, including about 180,000 in Ohio, endured a heat wave without power due to the outages.
Heat-related illnesses are a major concern
Although most heat-related illnesses are preventable through awareness and intervention efforts, they remain the leading cause of weather-related deaths in the United States, according to the U.S. Environmental Protection Agency. environment.
Extremely high temperatures can lead to common heat-related conditions, such as heat stroke and heat exhaustion, which occur when the body is unable to cool itself properly. It can also put significant pressure on the heart and make it harder to breathe.
Infants, children, the elderly, and people with chronic illnesses or mental health conditions are particularly vulnerable to heat-related illnesses, although young, healthy people can also be affected if they engage in activity. intense at excessive temperatures, according to the CDC.
Although children don’t die as much from heat-related illnesses as the elderly, a study published in January found that ‘climate shocks’ like sweltering heat waves can cumulatively affect a child’s long-term health. . Over time, such events can contribute to significantly higher rates of substance abuse and health problems like cancer and heart disease, the researchers said.
As climate change drives temperatures up, scientists expect the heat to make even more people sick, especially as heat waves become more frequent.
In the 1960s, Americans experienced an average of two heat waves per year, but in the 2010s the average rose to six per year, according to the EPA.
