Southern California braces for a multi-day heat wave with temperatures soaring into the 100s

After a brief respite, Southern California is slated for another intense heat spell starting Tuesday, according to one outlet Weather Service. Forecasts call for daytime highs climbing into the 90s and low 100s across inland communities, while coastal locations will see more modest rises. A heat advisory will cover most of the region through Thursday, with nighttime lows lingering in the 70s in Los Angeles County valleys and not dropping below the 80s in some foothill and mountain areas.

Woodland Hills and Santa Clarita are projected to top the regional temperatures at 103 degrees, with Palmdale, Burbank and downtown Los Angeles also reaching near-100-degree marks. The ridge of high pressure over the desert Southwest is responsible for the heat, which is also prompting extreme warnings in Nevada, Arizona and southeastern California, where nearby cities such as Las Vegas and Phoenix are forecast to exceed 100 degrees.
