Another cold storm will hit the region today, generating light rain in the Greater Los Angeles area starting as early as this afternoon, followed by snow over Interstate 5 through The Grapevine, forecasters said.
Temperatures, meanwhile, will remain low, with highs around L.A. and its environs mostly remaining in the 50s.
The rain will start in San Luis Obispo and Santa Barbara counties then spread southeast to Ventura and Los Angeles counties, National Weather Service forecasters said.
The storm—the second Pacific storm this week—is expected to generally produce between a 10th and a quarter of an inch of rain in the Southland, but up to a half-inch along south-facing slopes in the San Gabriel mountains in both Los Angeles and Ventura counties, they said.
"It looks like this will be a fast-moving system as the rain should end by early Saturday morning,'' according to an NWS advisory, which said the snow level would fall to between 3,000 and 4,000 feet tonight.
"There could be an inch or two of snow across the Interstate 5 corridor through The Grapevine Friday night, which may affect travel over The Grapevine," according to the advisory.
Dense fog also may shroud mountain roads tonight and early Saturday, creating "wintry driving conditions,'' especially above 3,500 feet, while at lower elevations there could be ponding, "especially in areas where drains have not been cleared," it said.
The weather will remain unsettled next week, when "a series of storms" could target the region, it said. Showers are expected Sunday, and rain is in Tuesday's forecast. The NWS forecast highs today of 58 degrees in Moorpark. A gradual warming trend will begin Saturday, when the highs will be a few degrees higher.
