Patchy to dense fog will develop tonight into early Friday from the coast to the valleys.
Visibility could be reduced to under a mile. Low clouds will extend farther east, as the marine layer deepens Sunday into Monday. Friday will be nearly as warm, before cooling begins this Mother's Day weekend.
A storm will pass to our north this weekend bringing cooler but pleasant weather for Mother's Day Weekend. The marine layer will spread farther inland and take longer to clear while gusty winds will target the mountains and deserts. Expect westerly gusts of 25 to 50mph each afternoon and evening in the mountains and deserts through Monday.
Mother's Day will bring mid to upper 60s at the coast, low to mid-70s inland, low-60s in the mountains and mid-90s in the deserts with morning clouds for the coast and valleys clearing to sunshine, though some coastal areas may only see partial clearing.
Greater cooling into next week with a deepening marine layer that may produce patchy drizzle to light rain by Tuesday and more of a May Gray type pattern. Temperatures will plummet 5 to nearly 30 degrees from today by Tuesday with the biggest drop in the mountains and deserts.
