A chance of light rain teases this morning as forecasters predict a 20% chance of rainfall. This is the result of a cold front that brought rain to San Luis Obispo and Santa Barbara counties overnight, although it weakened as it headed south, “bringing only a chance of light rain showers to Ventura and Los Angeles counties,” said a statement on the National Weather website.
The same is expected beginning later today, with a second cold front forecast to bring rain to San Luis and Santa Barbara counties this afternoon and tonight, then later tonight to Ventura and Los Angeles counties, it said.
An expected mass of cold and unstable air will create a slight chance of thunderstorms north of Point Conception, said the statement, adding that any thunderstorm will have the potential to generate heavy downpours and small hail.
The two-day event is expected to produce between a third and two thirds of an inch of rain in San Luis Obispo County, between a tenth and a third of an inch in Santa Barbara County, but less than a tenth of an inch in Los Angeles and Ventura counties, according to the NWS statement.
