Cooler temperatures are on the way to the Southland this week, along with some rain, forecasters said Sunday.
An unseasonably cold storm system will move over the region between Tuesday and Thursday, bringing rain and mountain snow, gusty winds and slight chance of thunderstorms, according to the National Weather Service.
Drizzle and light rain was forecast for Los Angeles and Orange counties Sunday night and Monday morning, with the potential for heavier rainfall Tuesday through Thursday, especially Thursday.
“We are still looking at a big change in the weather this week, with a storm system bringing rain & mountain snow Tue-Thu,” the NWS’ Los Angeles office tweeted Sunday afternoon. “Rain amounts between 1/3-1” and 4-8” snow above 5,000′.”
The weather service also reported a slight chance of thunderstorms Wednesday and Thursday.
In the Antelope Valley, a wind advisory was in effect until 10 p.m. Sunday, with gusts expected to reach up to 50 mph.
Sunday’s high of about 70 degrees in downtown Los Angeles was expected to drop to 62 Monday and 59 on Tuesday, with highs of 62 forecast Wednesday and Thursday. Highs were expected to linger in the low 60s in much of Los Angeles and Orange County through at least Thursday.
The NWS predicted a “good chance of a warming and drying trend for late week.”
