Heat wave hits US: See where it will be the hottest
Millions of Americans are under extreme heat warnings on Friday, June 20, as sweltering temperatures are expected to reach the triple digits in some areas.
The National Weather Service (NWS) stated that heat could reach "dangerous levels" over much of the central and eastern United States, beginning on June 20 and continuing into the weekend.
Temperatures are likely to be hottest between the weekend and early next week, but there will still be a risk for extreme heat in the Mid-Atlantic at the end of next week, the agency said.
According to AccuWeather, up to 170 million people across the country are expected to experience temperatures at or above 90 degrees during the heat wave.
Here is a look at which areas will be hit the hardest.
Midwest to be hit with hottest temperatures on Friday, Saturday
According to NWS data, the central U.S. is expected to endure the hottest temperatures on Friday, June 20, and Saturday, June 21.
On Friday, major heat-related impacts are expected in most of Nebraska, Kansas and parts of Colorado, South Dakota and Iowa. Pockets of surrounding states, such as Minnesota, Oklahoma and Louisiana, will also get the worst of the extreme heat.
By Saturday, major heat will expand across the Midwest, and extreme heat impacts will begin in parts of Nebraska, where temperatures could reach triple digits. Extreme levels are defined as rare or long-duration heat with little to no overnight relief, according to the NWS.
Extreme heat will move east by later next week
Extreme heat will continue moving east across the Midwest through the weekend, reaching Illinois, Indiana and Michigan by Sunday, June 22, according to the NWS.
Much of the remaining eastern half of the U.S. will also be under moderate to major heat-related risks, with temperatures likely reaching the high 90s.
By mid-next week, extreme heat will mostly linger across Ohio, Pennsylvania and the East Coast, per the NWS. States as far west as Illinois, Missouri and Arkansas will still have a moderate heat risk by Thursday, June 26.
NWS has specific temperature forecasts for all the U.S. states available on its website.

Central Ave.: 6 a.m. to 11 p.m. June 20-23 ― Karen Madden, Marshfield News-Herald With heat index values expected to reach values of 95-105 degrees during the afternoon hours on June 21 and 22 and 90-95 degrees June 23 across central Wisconsin, the National Weather Service in Green Bay has issued a heat advisory until 7 p.m. June 23 for central and northcentral Wisconsin, including Marathon, Portage, Wood, Lincoln, Waupaca and Waushara counties. A separate heat advisory has been issued for Adams, Clark, Taylor and Juneau counties. The highest heat indexes will occur from central Wisconsin to northeast Wisconsin, according to the advisory. Low temperatures in the mid- to upper 70s Saturday and Sunday night will provide minimal relief from the heat and humidity. The National Weather Service urges people to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check on relatives and neighbors. Take extra precautions when outside, wear lightweight and loose-fitting clothing and try to limit strenuous activities to early morning or evening, according to the weather service. ― Jamie Rokus, Marshfield News-Herald Young and elderly people and people who are pregnant or who have chronic health conditions are most vulnerable to high temperatures, Mike Cellitti, meteorologist with the National Weather Service in Green Bay, told a Marshfield News-Herald reporter Wednesday. The National Weather Service recommends increased awareness of these vulnerable populations during these types of high temperature events. No one should be left behind in a closed vehicle when temperatures are this high, Cellitti said. Six children nationwide died due to pediatric vehicular heat stroke so far in 2025, according to data gathered by Jan Null at San Jose State University at In 2024, 39 children died by pediatric vehicular heat stroke. Humane World for Animals, formerly The Humane Society of the United States, also warns pet owners to never leave pets in unattended vehicles for any period of time. On warm days, the temperature in a car can exceed 120 degrees in a matter of minutes, even with the windows open and pets can suffer brain damage or die from heatstroke or suffocation, according to the animal welfare organization. High humidity, like that expected this weekend, amplifies the negative impact of high temperature on your pet. Other tips for hot temperatures include taking frequent breaks in shade, drinking plenty of water and wearing loose-fitting clothing, Cellitti said. Check in on vulnerable people. Pets also should be provided with shade and water when they are outdoors during heat waves, and exercise should be limited on hot days, according to the animal welfare organization. ― Erik Pfantz and Jamie Rokus, Marshfield News-Herald This article originally appeared on Marshfield News-Herald: Heat advisory issued for Marshfield area: Here's what to know

Millions of Americans Warned of 'Dangerous, Life-Threatening' Conditions
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. AccuWeather meteorologists are warning of "dangerous, life-threatening" conditions for millions of Americans as a heat wave is moving across large portions of the U.S. later this week, with temperatures expected to top 100 degrees Fahrenheit across several states. Millions of Americans are expected to face major or extreme heat risks in the coming days, with the National Weather Service projecting over 152 million affected on June 23. Why It Matters Extreme heat is the deadliest weather hazard in the United States, posing serious health risks nationwide. Over 200 people died of heat-related illnesses in the U.S. last year. Since 1979, more than 14,000 Americans have died from heat-related causes, according to the Environmental Protection Agency. A "heat dome" is moving through the U.S., later this week, with millions of Americans across a range of large cities to be impacted. Several extreme heat warnings and heat advisories have been issued across cities and states. The heat wave coincides with the longest days of the year, with Friday marking the summer solstice. What To Know "The highest temperatures so far this year will combine with increasing humidity and intense summer sunshine to create dangerous, life-threatening conditions for roughly 170 million people," AccuWeather meteorologists said about the upcoming heat wave. The NWS predicts that on June 21, 62.5 million will be under major or extreme heat risk, 141 million on June 22, 152 million on June 23, 144 million on June 24 and 105 million by June 25. The NWS Weather Prediction Center similarly warned that "extremely dangerous levels of heat" are likely over the Central and Eastern U.S. These levels "may exacerbate the heat health impacts, especially by midweek," a June 20 message from the center said. The sun rises behind the skyline of midtown Manhattan and the Empire State Building in New York City, a day ahead of the summer solstice and an expected heatwave on June 19, 2025, as seen... The sun rises behind the skyline of midtown Manhattan and the Empire State Building in New York City, a day ahead of the summer solstice and an expected heatwave on June 19, 2025, as seen from Jersey City, New Jersey. More Photo byAreas of particular concern include the Ohio Valley, eastern Great Lakes, interior South and much of the East Coast, according to a warning from the NWS. In addition to record-high temperatures, those regions are expected to "lack overnight cooling," which will "significantly increase the danger." Heat index values—how the temperature feels to the body when humidity is factored in—were expected to reach triple digits in some areas that have Extreme Heat Warning issued by the NWS. Large U.S. cities have begun issuing warnings to residents ahead of the heat wave. In Annapolis, Maryland, officials posted an alert on the city's website and announced the activation of cooling centers "to provide temporary relief from extreme heat conditions and help prevent heat-related illnesses," as temperatures are expected to exceed 100 degrees and may reach 110. What People Are Saying AccuWeather Chief Meteorologist Jonathan Porter said: "Extreme heat is tragically the leading cause of weather-related fatalities in America. There is an amplified risk of heat-related illnesses because this is the first heat wave of the year for millions of people, and their bodies are not yet acclimated to this type of heat and humidity." Ben Noll, a meteorologist for The Washington Post, said on X, Wednesday: "A heat dome will form over central states on Friday before expanding and intensifying. Heat domes are large and strong heat-trapping lids of high atmospheric pressure. This one will last around a week, with numerous temperature records expected to fall." AccuWeather Chief On-Air Meteorologist Bernie Rayno said: "It will be exceptionally warm at night with little relief once the sun goes down. Many urban areas may struggle to drop below 80 at night, and that can take a toll on the body without air conditioning." Kevin J. Simmons, Director of the City of Annapolis Office of Emergency Management said in a Friday statement: "Heat waves like this one pose a serious risk, especially for our most vulnerable neighbors. We are asking all residents to take this heat seriously. Check on your neighbors, stay hydrated, limit outdoor activity, and know where to go if you need to cool down. Our goal is to keep everyone safe and informed throughout this dangerous weather event." National Weather Service wrote in an X, formerly Twitter, post on Wednesday: "Triple-digit heat indices will be common through next week, with oppressive humidity. Record-breaking heat will be dangerous to those working and playing outdoors so take precautions." What Happens Next The NWS warns, "This level of heat can be hazardous to anyone without effective cooling and/or adequate hydration, especially those engaging in lengthy outdoor activities."

Extreme Heat Warning issued for Cook County, including Chicago; Heat Advisory and Watch in effect for rest of area
The National Weather Service upgraded Cook County and Chicago to an Extreme Heat Warning starting Saturday morning and lasting into next week for an early summer heat wave building in our area. Chicago can expect three consecutive days with a peak afternoon heat index over 100 degrees. The rest of the Chicago area is either under a Heat Advisory or an Extreme Heat Watch, also beginning Saturday morning. The Extreme Heat Warning takes effect at 10 a.m. Saturday, and lasts through 12 a.m. on Tuesday, June 24, and covers the entire county, including Chicago. A Heat Advisory has been issued for Boone, DeKalb, DuPage, Will, Ford, Grundy, Kane, Kankakee, Kendall, La Salle Lake, Livingston, McHenry, Ogle, and Winnebago counties in Illinois and Benton, Kasper, Lake, Newton and Porter counties In Indiana from 10 a.m. Saturday through 12 a.m. Tuesday, June 24. An Extreme Heat Watch has been issued for La Porte County in Indiana from 8 a.m. Saturday until 8 p.m. Tuesday, June 24. Under an extreme heat warning, outdoor activities should be canceled and you should try to limit your time outside. If you don't have air conditioning, make sure you know where your nearest cooling center is, and/or make arrangements to stay with friends and family who have air conditioning. You should also check on your elderly neighbors and people who may need help in their day-to-day lives. These warnings, watches and advisories stem from a heat dome in the Midwest that puts millions of people at risk with high temperatures and stifling humidity. The Chicago heat index over the weekend is supposed to be in the triple digits, feeling like 100 to 105 degrees. Climate change is making heat waves like this more frequent and more intense. Saturday is expected to be Chicago's first 95 degree day of the summer, coming several weeks earlier than average. Over the last 30 years, Chicago typically records its first 95 degree day July 8. Record high temperatures in the upper-90s are expected in the city Sunday and Monday. Overnight low temperatures are also expected to be record-setting, hardly dropping below 80 degrees in Chicago Saturday and Sunday mornings with high humidity in place. Summer nights in Chicago have gotten 3 degrees warmer than they were in 1990 as the climate warms. Nighttime heat can exacerbate a heat wave's impacts, not giving those without access to sufficient air conditioning a chance to cool off, and increasing the cumulative heat stress on the body. Climate Central found that all but one of 247 U.S. cities analyzed are seeing warmer summer nights as the climate changes How to stay cool during the Extreme Heat Watch Cook County and Chicago cooling centers are available for anyone who does not have air condition and needs to cool off. Chicago has six permanent cooling centers, including Garfield Center, which is open 24 hours. The other five locations are typically open 9 a.m. to 5 p.m. Monday through Friday, but their hours are often extended during heat waves in the city. Click here for more information. There are also 34 cooling centers around Cook County, many of which are open 24 hours during severe heat waves or if needed. Click here to see a full list of county cooling centers. Additionally, public libraries and police stations throughout the city of Chicago and Cook County are often open on weekends for anyone who needs access to air conditioning and water. Chicago Public Libraries have water fountains available for public use. All of Chicago's public swimming pools and splash pads open Saturday as well. Outdoor pools will primarily be open 11 a.m. to 7 p.m. but, for the first time since 2020, they are all open seven days a week. Heat exhaustion and heatstroke: Symptoms and how to treat Heat exhaustion and heatstroke are major risks during a heat wave, especially with high humidity. It is easy to become overheated and dehydrated in high temperatures, so it is essential to make sure you are drinking enough water. Heat exhaustion is milder than heat stroke. It can develop after several days of exposure to heat and inadequate or unbalanced fluid replacement. Heatstroke is a serious illness that happens when the body begins to lose its ability to regulate its own temperature and functions, and can result in permanent disability or death if not treated as quickly as possible. Heat exhaustion symptoms include headache, nausea, dizziness, weakness, irritability, thirst, heavy sweating, high body temperature and decreased urine output. If you or someone you know is experiencing heat exhaustion move into a cool indoor space or shade immediately, give them liquids to drink, remove unnecessary clothing including shoes and socks, used cold water or a cold compress to cool the person down on their head, face and neck, and frequently sip cold water. The CDC also encourages calling 911 or taking the person to an urgent care clinic or the emergency room for treatment. Heatstroke symptoms include confusion, altered mental status, slurred speech, hot and dry skin or profuse sweating, very high body temperature, loss of consciousness, and very high body temperature. If treatment is delayed, it can quickly become fatal, the CDC says. If you are with someone experiencing heat stroke, call 911 immediately and stay with that person until help arrives. Move them into a shaded, cool area and remove their outer clothing then work to cool them down as quickly as you can with cold water or an ice bath if possible. Wet the skin or place cold, wet clothes on the skin, or soak their clothing with cold water. You should also circulate the air around them by fanning to help cool them off. The CDC also recommends placing cold wet cloths or ice on the head, neck, armpits and groin to help cool them faster.
