Eureka, CA – Drivers along the Humboldt County coast could face foggy roads and light rain through Saturday morning as a damp Pacific air mass lingers along Northern California’s shoreline.
According to the National Weather Service office in Eureka, a 30% chance of rain continues overnight with patchy fog and lows near 48°F, creating reduced visibility in coastal communities. Light showers remain possible into Saturday morning before gradually tapering off late morning.
Rain chances increase slightly to 40% early Saturday, mainly before 11 a.m., with cloudy skies and highs near 57°F across the Eureka area. Roads along U.S. Highway 101, State Route 255, and local coastal routes near Humboldt Bay could see slick spots during the morning commute as mist and drizzle move inland.
Conditions begin improving Saturday night as fog redevelops but rain tapers off. By Sunday, skies clear across Eureka, Arcata, McKinleyville, and surrounding Humboldt County communities, allowing temperatures to climb to around 63°F with sunshine returning to the North Coast.
The warming trend continues early next week with calmer weather and mostly sunny conditions expected Monday and Tuesday. Officials advise drivers to slow down in fog-prone coastal areas overnight and early Saturday as visibility may briefly drop below one mile.
