130 million people on alert as hot, sticky weather expected from Texas to Maine
At least 130 million people from Texas to Maine are under alert for dangerous heat and humidity over the next few days. Hot and sticky temperatures will make it feel as high as 115 degrees in parts of the Mississippi River Valley. Even Niagara Falls will get no relief from the sweltering conditions; the tourist destination will feel like the mid-to-upper 90s on Thursday. The heat index in Chicago, which factors in humidity, will make it feel in the triple digits and nighttime and early-morning temperatures will provide little comfort. As of 4 a.m. Thursday, the actual temperature was 80 degrees, or 85 with the heat index. Texas will be just as hot on Thursday, as the heat index is expected to make it feel 107. Up north in Detroit, it's forecast to feel 102. Dangerous heat will spread to the Mid-Atlantic and Northeast as temperatures in the I-95 corridor from Washington, D.C., to Portland, Maine, will make it feel like it's in the mid-90s on Thursday. Maine is under a heat advisory mainly for Friday as the heat index will make Portland, Maine, feel like it's 100 degrees. New York City, Boston and Philadelphia are also bracing for extreme temperatures. On Friday, the feels-like temperature is expected to be reach 104 in New York City, 103 in Boston, 106 in Philadelphia and 109 in Washington, D.C., and Baltimore. Meanwhile, the Midwest and the Southeast is expected to see hot and humid weather stretch into the weekend and into early next, as the heat indices are expected to make it feel 110 degrees in some parts. MORE: Congressional committees push back on Trump administration's proposed NOAA budget cuts Most of the Southeast, including Atlanta, is expected to see a level four out four "extreme heat risk" on Monday and Tuesday as a potentially life-threatening heat wave continues in the region. Besides the heat, the Midwest, specifically Kansas and Missouri, is expected to see a summer flash flooding continue. Strong thunderstorms on Thursday could cause flooding across the region, which is still recovering from flash floods earlier this week.

Triple-Digit Heat Index Triggers Advisories in Nine States
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. Sweltering and "dangerous" heat with indices surpassing 100 degrees Fahrenheit across parts of nine states has prompted the National Weather Service (NWS) to issue warnings for millions of Americans. Newsweek has reached out to NWS for comment via email on Thursday. Why It Matters Extreme heat is the deadliest weather hazard in the United States, posing serious health risks nationwide. The National Center for Health Statistics found that between 2004 and 2018, an average of 702 people died in the U.S. due to "excess heat." In addition, NWS warns that "heat related illnesses increase significantly during extreme heat and high humidity events." Since 1979, more than 14,000 Americans have died from heat-related causes, according to the Environmental Protection Agency. Older adults, young children and people with chronic illnesses face the greatest risk from extreme heat. Prolonged heat waves can also strain local power grids as demand for air conditioning spikes. Extreme weather across the U.S. come amid the Trump administration's proposed cuts of nearly 25 percent to National Oceanic and Atmospheric Administration (NOAA) and staffing reductions at NWS. New Yorkers cross 41st Street and Fifth Avenue in Manhattan during a heatwave on June 25, 2025, in New York City. New Yorkers cross 41st Street and Fifth Avenue in Manhattan during a heatwave on June 25, 2025, in New York City. CraigWhat To Know The NWS has issued a slew of extreme heat warnings and heat advisories across much of the South and Midwest, as well as New Jersey and Pennsylvania. The weather agency warns that "dangerously hot conditions" are expected across portions of the states with some heat index values exceeding over 115 degrees Fahrenheit in Mississippi. Heat index values reflect how hot it feels when both temperature and humidity are factored in. Portions of Louisiana, Mississippi, Missouri, Tennessee, Kentucky, Arkansas, Illinois, New Jersey, and Pennsylvania are all under extreme heat warnings and heat advisories. Extreme heat has persistently baked the South and Midwest over the past few weeks, as well as flash flooding. Extreme heat warnings in the region advised people to "not leave young children and pets in unattended vehicles," noting that "car interiors will reach lethal temperatures in a matter of minutes." Warnings also note that "heat stroke is an emergency" and encourage those who are feeling "overcome by heat" to be moved to a shaded, cool location and call 911. The NWS encourages people to "drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors." In an update on Wednesday, the NWS noted that while the heat isn't necessarily surprising, "when triple digits during the day barely drop to 80 overnight, it becomes extremely dangerous. Extreme and record heat is likely throughout the South through next week with extreme impacts possible for those without adequate cooling or hydration." Heat advisories are in place across dozens of states on Thursday, with NWS in San Antonio, Texas, stating in a Thursday X post: "Today will be the hottest day for many locations in over a month." What People Are Saying Ben Noll, a meteorologist at The Washington Post wrote in a Thursday X post: "Extreme humidity and heat aren't going away — yet. Another surge of corn-effect humidity from Saturday to Wednesday could be even more intense than this past week." In another post he added: "It's not just central states that will feel extreme humidity and heat. The East will too — on Friday in the Northeast and Mid-Atlantic, before it settles into the Southeast, where there's an extreme risk (Level 4 out of 4) for heat-related impacts into next week." Representative Gabe Amo, a Rhode Island Democrat, said in an X post: "Trump is gutting @NOAA and @NWS while climate change is causing catastrophic extreme weather. @RepHuffman and I introduced my Stop NOAA Closures Act so the President can't close labs predicting storms & leave Americans vulnerable to disasters." What Happens Next The NWS Little Rock, Arkansas forecast warns that "Dangerous heat index values will persist through next week and perhaps longer as high pressure prevails over the mid south."

Tracking heat: Here's where it will feel like 110 degrees
Dangerous heat is peaking today for millions in the central United States as a heat dome in summer's hottest month lives up to its reputation — but sauna-like conditions are only just beginning for areas farther east. The heat index — how hot it actually feels given the temperature and humidity — will top out in the 100s from the Gulf Coast to the Midwest Thursday afternoon while it soars above 110 degrees in some parts of the Mississippi Valley. Memphis, Tennessee, had its hottest day of the year so far on Wednesday with a high of 97 degrees and a heat index of at least 106 degrees. The city could match that intense heat Thursday while just south in Greenville, Mississippi, the heat index could hit 110 degrees. Farther north, Chicago's high temperature of 94 degrees could come within a degree of its hottest day so far this year. That same roasting summer heat started creeping into the Mid-Atlantic and Northeast Thursday. High temperatures in the 90s are likely Thursday afternoon as far north as Burlington, Vermont – located about 30 miles from the Canadian border. The worst heat for the East arrives Friday with high temperatures in the middle to upper 90s expected from Washington, DC, to Boston. These temperatures are up to 10 degrees higher than the typical hottest conditions for this time of year and could challenge the high temperature record for the day in Baltimore, Philadelphia and New York City. The heat index will reach or surpass 100 degrees for many major metros: Washington, DC, and Philadelphia will feel more like 105 degrees Friday afternoon and Baltimore will feel nearly 110 degrees at times. Heat remains the deadliest form of extreme weather in the US. Globally, heat waves are becoming more frequent, more severe and lasting longer as the world warms due to fossil fuel-driven climate change. More than 60 million people in the eastern half of the US are under at least a Level 3 of 4 'major' heat risk on Thursday, with that total jumping to more than 90 million on Friday, according to the National Weather Service. Heat this severe impacts anyone without access to effective cooling or proper hydration, not just vulnerable populations, according to the National Oceanic and Atmospheric Administration. And for those without air conditioning, staying indoors can become deadly during the hottest parts of the day, the agency warns. Humid conditions will also prevent temperatures from cooling significantly overnight. It could still be close to 80 degrees in Washington, DC, by sunrise Saturday — nearly 10 degrees higher than a typical low for late July. When overnight temperatures don't cool down enough to offer relief for overheated bodies, people are at greater risk for heat-related illnesses. Nighttime temperatures are taking the hardest hit from climate change, warming faster than daytime highs. Climate change is making this week's heat wave at least three times more likely for nearly 160 million people, almost half the US population, when compared with a world without fossil fuel emissions, according to an analysis from the climate research nonprofit Climate Central. The heat dome will shrink Saturday, replaced by more typical, though still very toasty, late July conditions parts of the Northeast and Midwest. Sweltering heat will persist through the weekend, mainly in southern parts of the Ohio Valley and Mid-Atlantic on Saturday and in portions of the Southeast Sunday. That general trend of a hotter-than-normal South is expected to continue through next week, according to the latest Climate Prediction Center forecasts. CNN Meteorologist Briana Waxman and CNN's Luke Snyder contributed to this report.
