This means that one-third of the US population is subject to heat advisories and excessive heat warnings today and tomorrow, and that more than 80% of the US population (approximately 265 million Americans) will see a maximum above 90 degrees over the next seven days.
The highest temperatures, pushing well into the triple digits, will again be centered over the southern plains.
More than two dozen records are possible today and tomorrow for the southern United States, including Texas, Oklahoma and New Mexico, and the east coast is also about to enter the mix. .
Parts of the northeast will also have temperatures near daily records on Wednesday and Thursday.

After a day of record heat yesterday, the southern plains are once again facing dangerous heat.
Dallas came close to its daily high of 110 degrees yesterday but hit 109 degrees, making it the hottest day of the year so far.

Oklahoma City could see highs near 110 degrees today, which would shatter its daily record of 109 set in 1936.
“The last time we had a significant warm spell was in 2011, when we had 63 days at or above 100 degrees,” said Vivek Mahale, a meteorologist with the Norman National Weather Service.
Mahale expects the above-average heat to continue through at least Sunday, with each day hitting the triple digit mark. Will Rogers World Airport in Oklahoma City experienced nine days above 100 degrees this month.
