Southern California is preparing for a significant change in weather, transitioning from a sustained period of high temperatures to cooler and wetter conditions. The National Weather Service is forecasting a 70% chance of precipitation, with rain expected from Thursday through Saturday in Los Angeles and Ventura counties. This follows a record-breaking heatwave in March, during which temperatures in Woodland Hills reached 102°F (39°C) and Lancaster hit 93°F (34°C). The recent heat was exacerbated by Santa Ana winds, contributing to local wildfires.
