More than 100 million people in the United States face excessive or heat warnings as the dangerous heat wave continues

“Dangerous heat will continue to affect much of the United States this week, with more than 100 million people currently under severe heat or heat warnings,” the Weather Forecast Center said.

This means that a third of the US population is subject to heat and overheat warnings today and tomorrow, and more than 80% of the US population (about 265 million Americans) will see a rise above 90 degrees within the next seven days.

The highest temperatures, which rush well into the triple digits, will again be centered over the southern plains.

More than twenty record highs are possible today and tomorrow for the southern United States, including Texas, Oklahoma and New Mexico, and the East Coast are about to get into the mix, too.

Parts of the northeast will also see temperatures approaching daily records on Wednesday and Thursday.

“Heat warnings are now in effect for parts of the Northeast, including the I-95 corridor from Philadelphia to Boston, where Heat Index values ​​are expected to reach nearly 100 degrees,” the Weather Prediction Center said.

After a record-breaking hot day yesterday, the Southern Plains faced dangerous heat once again.

Dallas approached its daily record of 110 degrees yesterday but passed 109 degrees, making it the hottest day of the year so far.

But today it will be worse.

Temperatures are expected to reach 111 degrees in the region, breaking the daily record of 108 degrees.

Severe heat has strained Texas’ power grid, as the state expects another day of record power demand.

Excess heat and heat warnings are in effect through Wednesday in North and Central Texas.

“Air temperatures will rise to 105 to 110 degrees in the warning area, with heat index values ​​over 105 degrees in the advisory area,” the Fort Worth National Weather Service said.

With high temperatures, low humidity, and wind speed, critical fire danger is also in place in North Texas and Central Oklahoma.

Oklahoma City could see highs close to 110 degrees today, which would break the daily record of 109 degrees set in 1936.

“The last time we saw a big spike in heat was in 2011, when we had 63 days of greater than or equal to 100 degrees,” said Vivek Mahal, a Norman National Weather Service meteorologist.

Mahale expects the above-average heat to continue until at least Sunday, with each day hitting the three-digit mark. Will Rogers International Airport in Oklahoma City saw nine days above 100 degrees this month.

He advised that the best thing you can do to prepare is to check for vulnerable populations where temperatures will be five to seven degrees above normal.

How to keep cool without air conditioning

“We really want to make sure that you want to check in with your friends, family and neighbors during the heat wave, especially vulnerable groups like the elderly,” Mahal said.

In the Far North, the Michigan Occupational Safety and Health Administration has encouraged employers to be aware of the dangers of heat and to help prevent heat illness.

“Whether you work indoors or outdoors, hot and humid conditions can pose serious health risks to workers, but heat-related illnesses are preventable,” Bart Beckelman, director of the Michigan Department of Occupational Safety and Health, said in a news release.

She added that employers should develop detailed procedures for monitoring the temperature index, saving water and caring for a sick employee.

New York, Boston and Philadelphia are preparing for a tough week ahead

BOSTON, MA - Warm weather brought people to the Esplanade in Boston in June.

Heat warnings are in effect tomorrow in the Northeast, including New York City, Boston and Philadelphia.

“The oppressive heat and humidity are back this week,” The Boston National Weather Service tweeted.

Heat index values ​​- the temperature you feel when you combine heat and humidity – can exceed 100 degrees in some areas, generating dangerous conditions for residents of the mid-Atlantic and New England.

Heat and humidity won’t just hug the coast. Northern New York State can also experience temperatures well above average.

Albany, New York rises above its average of 84 degrees this time of year, and the city could approach its record of 97 degrees tomorrow with the stifling heat.

To make matters worse, the humidity and heat make some areas feel 5-10 degrees high.

“This is going to be a little bit warmer than just the usual hot, humid weather we get in July,” Mike Evans, a meteorologist with the National Weather Service’s office in Albany, New York, told CNN.

Dew points could rise as much as 70 degrees tomorrow, Evans said, when the humidity becomes “very noticeable.”

Parts of Massachusetts will hit record highs as soon as Wednesday, as temperatures hit the high 90s, and will continue through the rest of the week in the Northeast.

“This is going to be our hottest day yet, this summer,” Evans said. “We haven’t had a very hot summer here, at least in the Northeast.”

The US is not likely to see much relief over the next week. The Climate Prediction Center expects above-average temperatures likely to persist into next week for most of the 48 lowest temperatures.
