NWS called the heat wave \u201chighly unusual and potentially record-breaking\u201d and said it \u201cwill bring a major to extreme risk for heat-related impacts\/illnesses.\u201d<\/p>\n
A \u201cmajor\u201d risk is labeled by NWS as affecting \u201canyone without effective cooling or adequate hydration.\u201d An \u201cextreme\u201d risk also affects those without cooling or hydration, but it also includes \u201cextreme long-duration heat with little to no overnight relief.\u201d<\/p>\n

CBS News<\/a> reported the weekend will feel hotter \u201cbecause of the high humidity that\u2019s arriving with it.\u201d <\/p>\n In the article, Nikki Nolan, CBS News meteorologist, said, \u201cMore than 100 record-high temperatures are expected through Saturday night.\u201d These high temperatures will be in places like New York City, Washington, D.C., Philadelphia, Baltimore, Chicago, St. Louis, Detroit, Dallas, Little Rock, Arkansas and Memphis, Tennessee, CBS said.<\/p>\n According to NPR<\/a>, the heat wave is from a heat dome, which \u201coccurs when a very hot air mass parks itself over a region and gets trapped under a \u2018lid\u2019 above the Earth\u2019s surface,\u201d it said. <\/p>\n How to beat the heat The National Integrated Heat Health Information System<\/a> has suggestions to stay safe in the extreme heat this weekend. <\/p>\n Its website said, \u201cExtreme heat illness and death are largely preventable with proper planning and preparing at all levels.\u201d<\/p>\n The advice includes staying inside with air conditioning on extreme heat days. When that\u2019s not possible, one should hydrate, seek shade and wear clothing that protects from the sun. When working or playing in the heat, the health information system says to take adequate breaks and avoid strenuous activity.<\/p>\n The severe temperatures can cause heat cramps, heat exhaustion and heat stroke, according to NIHHIS. If symptoms of those illnesses occur, such as dizziness, heavy sweating, nausea or confusion, people should take breaks or seek medical help if needed.<\/p>\n The U.S. isn\u2019t the only place experiencing unusually high temperatures. Another heat dome has been breaking records in Europe as well. <\/p>\n According to The New York Times<\/a>, the phenomenon started in Western Europe but moved east over the weekend. <\/p>\n One major difference between America\u2019s and Europe\u2019s heat waves are how people find respite from the weather. Air conditioning is a rare commodity in Europe; according to CNN<\/a>, 90% of U.S. homes have air conditioning, while only 20% of homes in Europe do.<\/p>\n \u201cIn Europe\u2026 we simply don\u2019t have the tradition of air conditioning\u2026 because up to relatively recently, it hasn\u2019t been a major need,\u201d said Brian Motherway, head of the Office of Energy Efficiency and Inclusive Transitions at the International Energy Agency, per CNN.<\/p>\n![\"\"](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2026\/06\/XOW6DAJSDVC7DP63ATQWHJNLYA.jpg\")
