The U.S. is experiencing an intense heat wave this weekend, with millions of people across the Midwest and East Coast facing dangerously hot temperatures.
The extreme heat is expected to last until midweek, affecting areas from Minnesota to Maine, as well as parts of Arkansas, Tennessee, Louisiana, and Mississippi.
The National Weather Service has issued heat advisories for these regions, warning residents to stay hydrated and avoid prolonged exposure to the sun.
What’s Causing the Heat Wave?
Meteorologists explain that a “heat dome” is behind the high temperatures. This phenomenon occurs when a large area of high pressure in the upper atmosphere traps heat and humidity, leading to dangerously high temperatures.
This heat dome is affecting nearly all areas east of the Rocky Mountains, making this heatwave especially widespread and unusual for early summer.
How Hot Is It?
On Sunday, the heat index—a measure of how hot it feels when humidity is factored in—reached over 100°F in cities like Chicago and Madison, Wisconsin.
This meant that even outdoor events like Madison’s annual naked bike ride became an uncomfortable experience due to the sticky, oppressive heat. In Philadelphia, the heat index was forecasted to reach a dangerous 108°F on Monday.
Heat Emergency in Philadelphia
As the heat continued, Philadelphia declared a heat emergency, which is expected to last until Wednesday evening. The city set up cooling centers in air-conditioned public places and a “heat line” for medical advice related to heat-related illnesses.
Fans attending Sunday’s FIFA World Cup match were allowed to bring a 20-ounce bottle of water to stay hydrated during the game.
Hot Conditions Across the East Coast
Across the East Coast, many cities are experiencing uncomfortable conditions. In Maryland’s Rehoboth Beach, beachgoers were trying to get outside before the heat made it unbearable. Even pets are feeling the heat, with some dogs reluctant to stay outside for long periods.
Cromwell, Connecticut, saw the heat index reach 105°F, making it especially challenging for golfers at the Travelers Championship. Fans at the event sought shelter under trees and air-conditioned benches, with some even lining up for water at hydration stations.
Impact on Sports and Health
The extreme heat is taking its toll on athletes as well. In St. Louis, Cincinnati Reds shortstop Elly De La Cruz fell ill from the heat during a game. Similarly, Seattle Mariners player Trent Thornton had to be removed from a game in Chicago due to the heat.
Forecasters warn that this heatwave will continue to impact daily life, including outdoor activities and sporting events.
The Heat Will Continue Into the Week
The heatwave is expected to shift eastward as the week progresses. Cities like New York, Boston, and Washington, D.C. are bracing for highs near or above 100°F, with heat indices pushing even higher. While such temperatures are common in mid-to-late summer, it’s unusual for this kind of widespread heat to hit so early in the season.
The ongoing heat wave is a reminder to stay prepared for extreme temperatures. Whether you’re outside for work or fun, be sure to take frequent breaks in the shade, drink plenty of water, and avoid strenuous activities during the hottest parts of the day.
As the heat dome persists, expect the high temperatures to continue impacting millions across the East and Midwest, with no immediate relief in sight.
