Late July’s oppressive heat forecast isn’t normal

As the clock progresses in the last days of July, the thermometers will climb most of the eastern half of the USA and will create a dangerous and long -term wave of heat that will risk millions of people at risk of heat and other diseases.

People on the path of heat wave should plan to take extra measures to stay cool at least on July 30th. Keep things cold by staying in air -conditioned areas, visiting friends with pools, saving Popsicles and lemonade and taking recipes for your favorite cold summer salad.

“This will be a long wave of heat that causes a long time, causing a danger,” the National Weather Service Weather Service Air Forecast Center, “This one night relief and high humidity levels are too little or not at all, causing a danger.

According to July 25 forecast at the forecast center by Jennifer Tate, the daily heights up to the last to 100 degrees of the 100s over the 90s are expected to unite with moisture to create conditions in which “similar” temperatures can exceed 110-115 degrees.

A high -pressure dome sitting in the eastern part of the country helps to capture the heat, while the abundant moisture in the air will make the real temperatures feel a few degrees warmer. Unusual heat and humidity can distract for several days and maintain the risk of heat in large categories by the end of the month in most of the Eastern United States.

Jennifer Tate at the weather forecast Center said on Friday, a dangerous heat, Tennessee Valley/Middle-South Region/Middle-South Region and Southeast Carolinas, he said. The lowest levels in the morning in the 70s “will not provide much relief.” To the north, the Middle West, the Ohio Valley and the Middle Atlantic can wait for warmer temperatures to 90s than usual.

Forecast maps from the Weather Service are covered in the United States in purple, red and orange warm tones and show intense heat. Until 30 or 31 July, Ohio is expected to help cool in the Valley area.

According to the American Red Cross, everyone should definitely take extra measures to stay outdoors and keep their bodies safe.

Heat is not the only danger presented by conditions dominating the high pressure area. The interactions around the heat dome in the atmosphere are estimated to trigger storms, storms and heavy rains.

‘Not the heat wave of your grandmother’

It has always been hot in summer.

“We’ve always experienced heat waves, M Max Holmes, Chairman and CEO of the Woodwell Climate Research Center in Woods Hole, said,” We’ve always experienced heat waves. ” “But more intensity, more time and more often are much more.”

“This is what we expect exactly to happen,” Holmes said. “As the world warms, we see more ends and the extremes that take us. They kill us. They make us sick.”

Heat can be the most obvious, but there are also others, including drought and excessive rainfall that caused the deadly flash flood in the country of Texas Hill on July 4th. These extreme ends can be seen in the existing heat wave for record crushing temperatures under the high pressure area and intense rainfall in storms around the heat dome.

June 2025 Seventh registered in the hottest JuneAccording to the data of the national ocean and atmosphere administration.

In the first two weeks of July 2025, temperatures throughout the country were 1.5 degrees warmer than the last 30 -year normal. Historical data from the weather service show that the average temperatures in July are about 2.7 degrees warmer since 1950.

If a human body temperature is normally 98.6 degrees and 2.7 degrees heating, it will be equivalent to having 101.3 fever. In nature, such an increase has a similar effect, explains scientists.

Weather service data shows that an average night temperatures throughout the country are higher than high temperatures during the day. This means that landscapes, trees and buildings have no chance of cooling, so they can warm up the next day.

Why is it so hot? If you live in a city, the answer may surprise you.

According to NASA, excessive heat stress has increased more than twice the last 40 years and this tendency is expected to continue.

An analysis made by Climate Central, Published on July 21, the last extreme heat of human -based climate change made at least three times more likely for almost half of the US population.

“This is not the heat wave of your grandmother, Kr said Kristina Dahl, Central’s Vice President of Central. “Yes, July is usually a warm month, but climate change makes this heat wave significantly warmer and more dangerous than the heat waves of the past.”

How hot for people?

Long -term exposure to warmer temperatures can cause serious, life -threatening complications such as dehydration, a rapid or irregular heartbeat and exacerbation of existing medical conditions.

In recent studies, scientists have shown that the hottest temperature that the human body can withstand the temperature regulating capabilities is lower than commonly believed.

They came to rely on a measure known as wet bulb temperature to determine the dangers. It uses a thermometer with a wet wick on the bulb and measures the effect of moisture on temperatures. Moisture can disrupt the body’s basic cooling mechanism – sweat does not evaporate.

Scientists have previously thought about the hottest temperature that a human body could receive before losing the ability to regulate its own warmth.

A 2022 studies written by scientists at Penn State The real maximum temperature that people can take for long periods has concluded that it is lower using a wet thermometer, and even for young and healthy people, it is approximately 87 degrees lower in 100% moisture. In the study, the maximum temperature is probably lower between those who are at more risky, such as elderly and young children.

What can you do to protect yourself and others from extreme heat?

In short, Red Cross recommends:

• Know who is at risk most – Pay attention to elderly adults, young children, pregnant women, disabled ones, or medications for chronic health conditions, lonely people and athletes.

• Watery – Even if you are thirsty and sugary drinks, caffeine and alcohol, for water every 20 minutes.

• Stay cool -If your house gets too hot, limits open -air activity and wear light, loose clothes. If your air conditioner goes out, it can be more cool in the shade than staying in the house.

• Rapidly – Cramps, heavy sweating, humid skin, dizziness, fainting or nausea and vomiting such as heat exhaustion or strokes such as developing measures to quickly cool measures. Move them to a cooler place, remove extra clothes and cool with a wet cloth or a cool bath and sip the water or sports drink, but “energy” drinks.

Where can you get more information?

There are resources to learn more about the dangers of heat -related diseases and how to help you and others safe, but not as before. A temperature risk that was protected by disease control and prevention centers to monitor heat and heat diseases has been excluded this year and is no longer active. The website is still available, but no new information is added.

Trump management officials took steps to prevent what they call climate alarmism, and now they changed their statements about climate change that was not included in the environmental protection agency’s home page and stopped protecting other websites, for example Climate.gov And Disease Control and Prevention Center to monitor heat risk and heat diseases. A tool on the CDC page now shows An error message.

The reporting of the administration by the government department of the government shows that more than 350 grants, which are mentioned in climate change, including dozens of heat mentioned, have ended.

NOAA’s budget for next year will no longer support the national integrated heat health information system, he said, Federal website about heat and heat -related diseases This brings together information from noaa and more than a dozen other departments and agencies. For now, the comprehensive guide initiated to try to reduce the rising rate of heat diseases in the United States during Biden management is still online.

For Holmes, most of the information is concealed, not political, but real.

“There are combinations of temperature and humidity that the human body cannot tolerate.” He said. “Trying to hide the truth will not help people.”

“I see zero justification because he tries to bury this information. It is embarrassing for our government to do so,” he said. “Partisan is not something, it’s something.”
