"Record-Breaking Heatwave Sweeps Across Southern California and Arizona for Fourth of July Weekend"

The Inland Empire and desert communities in Southern California are experiencing triple-digit temperatures as a heatwave settles over the region, prompting an excessive heat warning. The hot air mass is expected to linger until midweek, with Saturday and Sunday being the hottest days. While July 4th is forecasted to be sunny, coastal fireworks may be limited by evening clouds. This comes after an unseasonably cold June, where high temperatures failed to reach 80 degrees, breaking records for the least number of days above 80 degrees in the first half of the year.
