Los Angeles, CA – A building ridge tied to a migrating heat dome is set to push temperatures into the upper 70s and mid-80s across Southern California within days, while dry conditions increase wildfire and drought concerns through early April.
According to the National Weather Service Climate Prediction Center, Southern California falls within a 50 percent probability of above-normal temperatures from April 3 through April 9, paired with a 50 percent chance of below-normal precipitation. Highs in Los Angeles, San Diego, and Riverside are expected to run 5 to 10 degrees above seasonal averages, with inland valleys seeing the warmest conditions.
Unlike the stormier pattern east of the Rockies, Southern California sits firmly under the western edge of the heat dome, where sinking air suppresses cloud formation and limits rainfall. This setup supports extended dry periods with only occasional marine layer clouds near the coast.
Rain chances remain minimal across the region, with little to no measurable precipitation expected along major corridors including I-5, I-10, and U.S. 101. Dry fuels and warming temperatures could elevate fire weather concerns, especially in inland and foothill areas.
Residents are urged to conserve water, avoid activities that could spark fires, and prepare for warm afternoons with limited overnight cooling inland.
This pattern is expected to persist through April 3–9, with additional updates likely if fire weather concerns increase.
