A low pressure system moving inland across southern California and northern Baja will bring rain and higher elevation this morning, then periods of showers for this afternoon through tonight with a slight chance of thunderstorms for this afternoon and evening. Rainfall and liquid-equivalent above the snow level is expected to range from one-third to two-thirds of an inch with local amounts exceeding one inch in the mountains.

A second low pressure system from the west will bring additional precipitation for Wednesday into early Friday with the most likely time for more widespread and heavier precipitation with the cold front for late Wednesday night into Thursday morning. For Wednesday through early Friday, rainfall could range from around one inch near the coast to 2 to 3 inches in the mountains with local amounts to around 4 inches for the coastal slopes of the San Bernardino County mountains. A snow level around 6500 feet will begin to lower from the northwest by Thursday morning, falling to 4000 to 4500 feet for Thursday afternoon and 3000 to 3500 feet by Friday morning. For the eastern San Gabriel Mountains for Wednesday morning through Thursday night, there is around an 80 percent chance for local rainfall and liquid-equivalent of 3 inches or more and a 20 percent chance for rainfall and liquid-equivalent of 5 inches or more.
