A storm system will slip along the coast tonight bringing central California a 40% chance of very light rain showers early Saturday morning. The Sierra will have light to moderate snow showers as low as 3,500-feet. As the storm drops farther south and inland Saturday night into Sunday there will be a slight chance of snow showers continuing in the high Sierra. As always after storms pass by there is a chance of overnight fog in the valley so watch for that from Sunday through Wednesday. Another storm system will bring a chance of rain again Wednesday night.
