A cold low-pressure system from the north will bring strong winds, chilly temperatures, widespread rain, mountain snow and even a chance of thunderstorms through the middle of the week, the National Weather Service said Monday.
The storm system will create hazardous travel, especially through mountainous terrain.
The windiest and wettest day will be Tuesday into Tuesday night, according to forecasters.
High temperatures Tuesday are predicted to reach 58 degrees along the coast, 57 in the western valleys, 47 to 52 near the foothills, 40 to 46 in the mountains, and 62 to 67 in the deserts, the weather service said.
After this system comes through the region, there will be a slow warming trend into next weekend, along with dry weather.
A low-pressure system may move over the western U.S. and bring areas of light Santa Ana winds across the mountains and foothills, according to meteorologists.
