The temperature in Long Beach reached a high of 108 degrees Sunday, breaking a heat record of 107 degrees set in 1988, according to the National Weather Service.

Record temperatures were also recorded Saturday in Lancaster, Palmdale and Sandberg. Lancaster’s 109 was one degree higher than the previous record of 108 set in 1955. Palmdale’s 106 tied the record set in 1947 and in Sandberg, near the Grapevine, Saturday’s 99 degrees broke the previous record of 97 degrees, set in 1955.

Excessive heat warnings were extended until at least 8 p.m. Wednesday for the mountains and the Santa Clarita, San Fernando and San Gabriel valleys, along with the inland coastal area, including downtown Los Angeles.

The warning in the Antelope Valley will last until 9 p.m. Wednesday, with temperatures anticipated up to 113 degrees.

In Orange County, excessive heat warnings are also in place through 8p.m. Wednesday for coastal and inland areas and the Santa Ana Mountains and foothills.

Orange County beaches were in the upper 80s on Sunday, with Anaheim reaching 105, Santa Ana expected to reach 103 degrees and Fullerton 107.

Overnight lows are not offering much relief either, staying in the 70sand even in the low 80s in some of the hotter areas.

“A prolonged period of very hot conditions with minimal coastal clouds is expected as high pressure aloft remains anchored over the West,” according to the National Weather Service.
