Map shows which states are facing dangerous heat
Multiple states are under extreme heat warnings, advisories or watches on Wednesday, July 23 due to a heat dome that is expected to slowly spread east, according to the National Weather Service. The NWS said the remainder of the week features a "strengthening heat dome over the Mississippi Valley today that gradually builds east towards the East Coast by week's end." The weather service said a combination of mid-upper 90s temperatures and humid conditions are a recipe for "oppressive heat indices that range between 110-115 degrees for many areas along and east of the Mississippi River" on Wednesday. By Thursday, July 24, the NWS says the footprint of heat is expected to move east into the Great Lakes and Northeast regions. "While this is not really a record-breaking air mass in terms of high temperatures, some towns and cities will struggle to drop below 80 degrees at night due to the high humidity levels and retention of heat by vast areas of concrete and pavement," AccuWeather Senior Meteorologist Brett Anderson said Wednesday. "For those that only have a fan or open window to keep cool, sleeping will be difficult for some, with a high risk of dehydration." AccuWeather says temperatures will reach 100 degrees from Texas to western Tennessee "just about every day" for the next week or two. See which areas are facing heat and humidity this week.

The heat index measures how hot it actually feels when factoring for humidity. Prolonged exposure to a 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. What is an extreme heat advisory? The weather service issues an Extreme Heat Warning when "extremely dangerous" heat conditions are expected or occurring. People in those areas are urged to avoid outdoor activities, especially during the heat of the day, and to check on family and neighbors. An Extreme Heat Watch is issued when conditions are favorable for an extreme heat event but its occurrence and timing are uncertain. People are warned to suspend all major outdoor activities if a warning is issued. 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." Gabe Hauari is a national trending news reporter at USA TODAY.

Temperatures forecast to be in 100s this weekend bringing ‘dangerously hot conditions' to Bakersfield, surrounding areas in Kern County
BAKERSFIELD, Calif. (KGET) — As temperatures are expected to reach 100 degrees and over in parts of the Central Valley, the National Weather Service has issued an Extreme Heat Watch for the weekend. The Extreme Heat Watch is in effect between May 30 at 11 a.m. through June 1 at 7 a.m. for much of Kern County including the Kern River Valley, the National Weather Service in Hanford said. The Old Farmer's Almanac predicts a 'very hot summer' in 2025 17 News Chief Weather Forecast Kevin Charette said temperatures in Bakersfield are expected to be in the low 100s on Friday and Saturday. The hottest recorded temperature this year was 102 degrees on May 10, he said. The average temperature for the time of year is 88 degrees, according to data from the National Weather Service. The National Weather Service's advisory says the 'dangerously hot conditions' could bring temperatures to 105 degrees in some areas. RELATED: Kern County doctor shares tips on staying safe amid rising temperatures The record high temperature for May 30 is 108, while the record high temperature for May 31 is 110. Both were recorded in 1910. Residents are encouraged to drink plenty of fluids, check on elderly relatives and neighbors and stay indoors in air conditioned rooms. Copyright 2025 Nexstar Media, Inc.

Why ‘excessive heat warnings' won't be part of the forecast
(NEXSTAR) — It may be hard to think about sweltering temperatures in early March, but the National Weather Service (NWS) is already rolling out changes to the weather alerts used to inform the public of the dangers of impending heat. Americans may be familiar with 'Excessive Heat Watches' and 'Excessive Heat Warnings,' issued when potentially dangerous heat conditions are in the forecast. Starting this month, those alerts will be no more — sort of. Like it did with wind chill alerts in fall, the NWS is adjusting the names of its heat watch and warning alert. Instead, dangerous heat conditions will trigger an 'Extreme Heat Watch' or an 'Extreme Heat Warning.' Why you'll no longer see 'Wind Chill Warnings' this winter The guidelines are the same as when they were considered 'Excessive' alerts. An Extreme Heat Watch can be issued when 'conditions are favorable for an extreme heat event but its occurrence and timing is still uncertain.' Guidance from the NWS encourages rescheduling outdoor events and ensuring the most vulnerable — children, the elderly, and pets — have a place to stay cool when watches like this are issued. When 'extremely dangerous heat conditions are expected or occurring,' an Extreme Heat Warning is issued. You may be encouraged to avoid outdoor activities, remain hydrated, and stay in air-conditioned spaces as much as possible. Renaming the heat watch and warning is part of NWS's Hazard Simplification Project, which is intended to 'better convey that heat is dangerous.' A total lunar eclipse and blood moon will be visible in March: How and when to watch Another heat-related alert, the Heat Advisory, will not be renamed. These are issued when dangerous heat conditions are likely but not severe enough to trigger a watch or warning. The specific conditions that prompt any heat alert vary by area. The NWS points to Florida, where residents are better prepared for 90-degree heat than in, say, Alaska. In Wisconsin, for example, daytime heat index values between 100 and 104, or heat indices between 95 and 99 for four consecutive days, can activate a heat advisory from the local NWS office. An extreme heat warning can be activated if the daytime heat index will be 105 or higher or 75 or higher at night for at least 48 hours. The NWS also provides a HeatRisk tool, a five-point scale that ranks the risk of heat-related impacts nationwide. It takes into account how unusual the high temperatures are for the time of year, how long the heat will last through the day and night, and if the temperatures 'pose an elevated risk of heat-related impacts' according to data from the Centers for Disease Control and Prevention.
