The weather is about to take a big twist on the Central and South Coasts, going from near record high temperatures to rain. A trough along the West Coast could drop high temperatures five to 15 degrees Saturday. The marine layer will also return, brining the chance of drizzle.
But, the big change is coming Sunday, with an upper low bringing even cooler weather and rain to the region. Rainfall amounts will be light, so there are no warnings or watches for flooding or debris flows in brush fire burn zones.
Rain totals could be in the tenth to the quarter of an inch range. If the low slows down, there’s also a chance of some thunderstorm activity. Snow level could drop to around 3000 feet, creating some hazardous driving conditions for Ventura and Los Angeles County mountains, as well as for travelers on I-5 through the Grapevine.
