Storm system expected to bring widespread rain, strong winds, and mountain storm to SoCal

A storm system is set to bring widespread rain, mountain snow and strong winds to parts of Southern California as early as Monday. 

Rain is expected to develop over Santa Barbara County by 6:15 a.m. and will move into Los Angeles County by 6:30 p.m., as well as into portions of the Inland Empire and Orange County. 

The rain is expected to continue through Tuesday evening to early Wednesday. Snow levels are expected to drop down to as low as 3,500-feet across the major mountain passes, causing a potential hazard for drivers in those areas. 

The storm system is expected to move out of the area by Wednesday evening, though showers will be intermittent during the day. 

As well, forecasters predict wind gusts of up to 40 mph Sunday night and Monday in the mountains and high desert, increasing to 55 mph Tuesday. 

The wet weather will be accompanied by chillier days and nights. Daytime temperatures are expected to drop into the low 60s in the valleys and the downtown Los Angeles area Monday through Wednesday, with lows in the 50s Monday and Tuesday and the lower 40s Wednesday, Thursday and Friday.

Wednesday's highs are only expected to reach 58 degrees in Pasadena and Santa Clarita and 53 degrees in Lancaster. The Antelope Valley will see overnight temperatures below freezing level later this week, with lows of 33, 30 and 31 degrees expected Wednesday through Friday.
