Southern California is set to experience a significant heatwave this week, with the hottest conditions expected from Wednesday through Friday. High pressure building over the region will drive temperatures up each day, with major to locally extreme HeatRisk anticipated away from the coast. Even coastal areas won't escape the heat, with moderate HeatRisk expected on Thursday and Friday.

While some cloud cover was seen over the mountains, any chances of rain remain minimal, with dry conditions forecast for the rest of the week. The marine layer will become shallower, leading to patchier low clouds, mainly along the coast. With elevated nighttime temperatures, residents should prepare for limited relief from the heat, stay hydrated, and avoid strenuous outdoor activities during peak heat hours.
