A stubborn marine layer brought light drizzle to Southern California's coast and valleys Tuesday, a precursor to an incoming cold front that likely will dump rain on the region this week.
The system will bring a 20% chance of light rain to Los Angeles around 8 p.m. Tuesday, said National Weather Service meteorologist Kathy Hoxsie. The chance of rain will increase to about 50% by Wednesday.
The rain is expected to linger into Thursday and clear up by Friday, when Hoxsie said temperatures are expected to warm from the 60s into the 70s.
"We welcome the rain, whatever we can get, but it's nothing on the order of what we had last month," she said. "We're not expecting much – it should be less than a tenth of an inch."
Hoxsie said there should be enough rain to get the ground wet. But if the rain is too light, oil will be lifted off roads but not washed away, creating slick conditions, she said.
The marine layer will likely remain through much of the day and is expected to return Wednesday as the rain rolls in.
