Eureka, CA – Light rain is expected to return to Humboldt County late Friday, bringing a brief wet stretch that could affect evening travel and weekend outdoor plans. Patchy fog will develop in some areas by Saturday morning, reducing visibility along coastal routes including U.S. Highway 101.
According to the National Weather Service, there’s a 30% chance of showers Friday night, with a stronger 40% chance Saturday morning before tapering off. Winds will be light, but damp roads and low clouds could slow drivers in Eureka, Arcata, and surrounding communities.
Most of Thursday and Friday will stay dry, with highs in the mid-60s, before clouds thicken ahead of the rain. Weekend conditions will shift between cloudy skies, occasional drizzle, and periods of fog. Sunday will bring a partial clearing, but early morning fog could persist.
Residents planning weekend events should prepare for shifting conditions, especially Saturday morning. Those traveling early should allow extra time and use headlights in fog-prone areas.
Rain chances diminish by Saturday night, with early next week expected to be partly sunny and seasonably mild.
