Soggy Southern Californians who are begging for a change in the gloomy weather pattern will get a slight change next week: the current scattered light drizzle is predicted to morph into scattered showers and possibly even thunderstorms by Monday, forecasters said Saturday.
"It's just not looking like we'll get too much of a break in the clouds and drizzle," said National Weather Service forecaster Bonnie Bartling at the Oxnard office. An approaching low-pressure system will arrive late Sunday and possibly transform the current strong coastal airflow into an actual, but weak, storm.
"It's not really not really a 'storm' storm, like we think of a winter storm," Bartling said. "It just looks like a draggy blob of low pressure."
Local news from across Southern California
On Sunday, the coastal plain in Los Angeles and Orange counties will weather that is virtually identical to Friday and Saturday, with fog and drizzle in the morning. But as the storm moves in Sunday night, drizzle will be replaced by a 40 percent chance for rain for the coastal plain.
Inland valleys and the San Gabriel Mountains will have a 50 percent chance of showers Monday and Tuesday. And the approaching storm will have enough instability and energy to raise the slight possibility of unusual autumn thunderstorms on both days.
