Cooler weather, clouds and more rain are expected this afternoon and Friday as the low pressure system moves across northern Baja California and the most southern reaches of California, Russo said.
Bands of heavier showers Friday afternoon into evening could drop from a half-inch up to an inch of rain over a six-hour period.
Lighter amounts of rain and possibly some snow, mainly near the mountains, could fall as a colder system approaches from the northwest late Saturday through early Sunday, Russo said. Gusty winds in the mountains and deserts are also expected.
The showers should decrease late Saturday through early Sunday, but more rain along and west of the mountains is expected through Monday night.
In all, the two systems could drop from .5 to .75 inches of rain along the coast and up to 1.5 inches of precipitation in the mountains, Russo predicted.
