Heat dome is here: It will feel like 100 degrees-plus to 100 million of us
ARLINGTON, Va. − A heat dome expanding across much of the Midwest and South will envelop over 100 million Americans with temperatures at or above 100 degrees on an almost daily basis this week, forecasters say. AccuWeather says that almost 200 million people will experience the triple digit "RealFeel" temperatures on Friday alone. The National Weather Service early on July 22 already had issued extreme heat warnings, watches and advisories across a swath of the nation, affecting more than 70 million Americans. Many cities that have not seen actual 100-degree temperatures so far this summer will hit the mark this week, AccuWeather warns. Many areas from Nebraska and Missouri to Texas and Louisiana won't even see overnight temperatures drop below the mid-70s or even low 80s. "Kansas City, Missouri, has not hit 100 degrees since Aug. 25, 2023, but is positioned to do so on multiple days during the upcoming heat dome," AccuWeather Senior Meteorologist Chad Merrill said. Much of the East was exempt from the heat dome on July 22 as residents in this suburb of Washington, D.C., saw temperatures drift into the 60s overnight with little humidity. The high for July 22 was forecast to reach only the mid-80s. The respite, however, won't last − by Friday the humidity returns with a forecast high nearing 100 degrees. Heat dome to push extreme temperatures across much of US this week What is a heat dome? Heat dome is not actually a scientific term, according to which says the term does effectively describe the "oppressive" high-pressure atmospheric systems that cause warm air to be pushed to the Earth's surface and trapped there for long periods of time. "The dome traps high-pressure air in one place, like the lid on a pot," the website says. "These large zones of hot air result in a combination of blistering temperatures, devastating wildfires, and drought conditions." The symptoms of heat stroke: What to know amid extreme heat warnings How long will the heat dome last? Jonathan Erdman, a senior meteorologist at wrote that the heat wave may last until at least the last weekend of July in the Plains and South, while slowly expanding west toward the Rockies. "Our longer range outlooks suggest the Northeast has the best chance of eventually seeing some heat relief around that last weekend of July," Erdman said. 'Corn sweat' will add to punishing heat, humidity in Midwest this week Corn sweat adding to Midwest heat, humidity It's high summer in the Midwest and the corn is "sweating." Known as evapotranspiration, it's a healthy process for plants that can worsen stifling heat for humans by driving up humidity levels. The process is how plants release water vapor into the atmosphere. The released water combines with other water molecules, humidifying the air. In the Plains and Midwest regions, where there are millions of acres of corn and soybean crops, it makes a difference. In Iowa, corn pumps out "a staggering 49 to 56 billion gallons of water into the atmosphere each day" throughout the state, the National Weather Service said. That can add 5 to 10 degrees to the dew point, a measure of the humidity in the air, on a hot summer day. Read more here. − Doyle Rice

Heat dome to push extreme temperatures across much of US this week
A bulge in the jet stream is conspiring with a large high-pressure system to create a "heat dome," bringing temperatures approaching triple digits that could linger into August across a swath of the Midwest and East, forecasters say. The Kansas City, Missouri, area, which hasn't seen 100 degrees in two years, could reach the figure multiple times this week, AccuWeather Senior Meteorologist Chad Merrill said. Dallas could see 100 degrees for the first time in 2025. Almost 85 million Americans from South Dakota to Texas and North Carolina to Florida were already under National Weather Service extreme heat warnings, watches or advisories July 21. The heat will intensify July 22 and deep into the week − and possibly beyond. "By midweek, 90s will have spread from the South into the Midwest and Great Lakes," wrote Jonathan Erdman, a senior meteorologist at Parts of Texas, Arkansas and Louisiana will have highs peak at near or above 100 degrees, and a much larger area of the South, Midwest and Great Lakes will see a heat index surpassing 100 degrees, he said. "This has the look of a long-lasting heat wave with limited rainfall," Merrill said. "Drought will expand through the central Plains by mid-August and worsen in Kansas and Nebraska, where there are already pockets of moderate to extreme drought." Angry storms, 'heat dome': Threaten to fuel dangerous weather week Brief respite for Northeast before heat dome advances The Northeast will enjoy a few days of lower humidity and cooler temperatures before a "bubble" from the heat dome slips away from the Midwest and brings brutal heat east, AccuWeather forecasts. Temperatures will dip into the 60s in New York and Washington, D.C., the 50s in Boston and into the 40s in some areas of the Northeast's interior. The respite will wrap up by Friday, when the high temperature for Washington is forecast to reach almost 100 degrees. Detroit will reach deep into the 90s Thursday and Friday. Philadelphia will push close to 100 Friday and Saturday. "The late-week scorcher heading into the East will be a quick whiplash," AccuWeather Senior Meteorologist Chad Merrill said.

On This Date: An Early 19th Century Vermont Long-Track Tornado
Almost 200 years ago, an early July tornado tracked through a part of a northern U.S. state among the least visited by twisters in history. On July 2, 1833, 192 years ago today, the town of Holland in Vermont's Northeast Kingdom was struck by a "violent tornado," according to "A History and Description of New England." Said to be up to three-quarters of a mile wide, the twister "prostrated and scattered nearly all the trees, fences and buildings in its course." The tornado first developed over Salem Pond, then tracked northeast into Canada, according to the authors of the book published in 1860. They also wrote, "Its course could be traced through the forests nearly to the Connecticut River." If that was indeed one long-track tornado, rather than multiple tornadoes generated by a supercell, its path would have been over 30 miles long. Only 50 tornadoes have been documented in Vermont in modern records since 1950, according to NOAA. That's an average of one tornado at least every other year in the Green Mountain State. The strongest documented tornado damage in Vermont was F2, from 14 different tornadoes from 1955 through 2002. (MORE: How Many Tornadoes In Your State?)

Is your state one of the hottest today in this heat wave? See heat index map
About 160 million people are currently being affected by a record-setting heat wave that extends from the Lower Mississippi Valley and Midwest to the East Coast, the National Weather Service said on June 24. Heat warnings, which began over the weekend, remained in effect across much of the country. Local officials on the East Coast have said many areas could experience conditions that "feel like" 110 degrees as the heat combines with humidity. AccuWeather meteorologists said high temperatures approaching and even exceeding 100 degrees are expected over more than three dozen states stretching from the Plains to New England through at least Tuesday, challenging many long-standing records. "The most significant cumulative heat impacts are anticipated across the Mid-Atlantic through Thursday and eastern Ohio Valley into Friday, leading to several consecutive days of oppressive heat," the weather service said Tuesday morning, urging people to stay cool and hydrated and to take action when they see symptoms of of heat exhaustion and heat stroke. Dozens of locations, especially in the Northeast, will be within striking distance of daily record highs, especially through June 24, said meteorologist Jonathan Erdman. Here's a look at which states feel the hottest during the heat wave and how long the heat wave is expected to last. Live weather updates: Temperatures soar to triple digits as heat wave scorches millions The map embeds below identify areas where the heat index is forecasted to reach NWS-defined levels from "Caution" (80 degrees Fahrenheit) to "Extreme Danger" (above 125 degrees). Heat index measures how hot it actually feels when factoring for humidity. Prolonged exposure to heat index above 80 degrees can lead to fatigue, as previously reported by USA TODAY. As it gets hotter, the risk continues to increase − potentially resulting in heat stroke or even death. Older adults, children, and outdoor workers are generally at higher risk of heat-related incidents. Heat index map for Tuesday, June 24 The fierce heat is expected to last through the first half of the week before easing, according to forecasters. According to AccuWeather, some cloudiness and rain will enter the forecast in some areas near the Great Lakes and Northeast beginning Wednesday, and while temperatures will come down from their peaks on Monday and Tuesday, they will still likely run well into the 90s for most in the mid-Atlantic. There are multiple forms of heat illnesses, but heatstroke is the deadliest and most dangerous, according to the National Park Service. The following are symptoms of heatstroke, according to the Centers for Disease Control and Prevention: Body temperature of 103 degrees or higher Skins that is hot, red, dry or damp Fast, strong pulse Headache Dizziness Nausea Confusion Losing consciousness In the case of a heatstroke, the CDC recommends people do the following: Call 911 immediately Move the person suffering from heatstroke to a cool location Lower the person's body temperature with a cool cloth or bath Do not give the person suffering from a heatstroke water or anything to drink Contributing: Doyle Rice and Thao Nguyen, USA TODAY Gabe Hauari is a national trending news reporter at USA TODAY.
