On Saturday alone, most of the continental United States will see heat of 90 degrees or more.
In the past week, more than 1,200 heat records and 159 July heat records have fallen across the country. Dozens of the highest temperatures of all time have also been recorded.
More records are expected as the heat wave spreads over the weekend and into next week.
Northeast
After a relatively mild week, the intense heat is expected to creep north this weekend. Boston and New York City expect high temperatures of between 90 and 90 degrees, between 15 and 20 degrees from earlier this week.
Philadelphia and Washington, DC, will see temperatures near 100 degrees early next week, continuing the scorching heat stretch in the region.
Dulles International Airport, just outside Washington, DC, had measured 20 consecutive days at more than 90 degrees through Wednesday, challenging its 21-day record.
And Pittsburgh, which expects temperatures in the mid-90s this weekend, has just had its longest 90-degree streak in 25 years.
The Northeast will continue to see intense heat until a cold front moves next Thursday.
South
Parts of the south will see heat rates near 110 degrees on Thursday, prompting the National Weather Service to issue heat warnings to about 10 million people.
Amarillo, Lubbock and San Antonio, all in Texas, set their July heat records in recent days. Borger, Texas, broke its historical record on Saturday by reaching 116 degrees.
This weekend will not be as intense as the record heat earlier this week. However, the region will still see stifling temperatures. Dallas expects high temperatures in the mid to upper 90s. And Oklahoma City could outshine 100 degrees on Friday.
Midwest
Chicago will see temperatures rise this weekend, reaching the mid-90s on Sunday, 10 degrees above normal.
Detroit will rise from the mid-70s on Thursday to the lowest 90s on Friday, and Minneapolis will see a high in the mid-90s on Saturday.
St. Louis will see highs near 100 degrees on Saturday and Sunday. The high temperature is not forecast to drop below 90 degrees for almost the rest of the month.
South west
Record heat in the southwest has slightly decreased in some places. However, the region is still forecast to be extremely hot.
Phoenix ended a streak earlier this week of not falling below 90 degrees for seven days and 22 hours, tying its all-time record. She also saw 11 days in a row with a high temperature above 110 degrees.
High temperatures in Phoenix are not expected to drop below 109 degrees for at least five days.
Extreme heat is also affecting southern California. Palm Springs, which set a daily temperature record of 121 degrees on Sunday, is forecast to hit 113 degrees on Sunday and Monday.
Last Sunday, Death Valley reached 128 degrees, the highest temperature on the planet since 2017.
Northwest
Most of the northwest will see above-average temperatures in the coming days. Portland will manage to avoid the higher temperatures until Saturday. However, its temperatures will rise to the lowest 90 degrees on Sunday and the mid-90s on Monday as the intense heat moves north.
Seattle will be one of the few places in the country to avoid the heat wave and will manage to stay in the 70s and 80s next week.
