Eureka, Calif. – Patchy fog and cooler evenings will keep Humboldt County residents cautious into Friday night, before brighter skies and gusty breezes take over the weekend. The National Weather Service in Eureka reported Thursday night’s low near 51 with clouds lingering, but a steady clearing trend arrives by Friday.
According to the National Weather Service Eureka office, skies will gradually brighten Friday with highs near 60. Overnight, patchy fog could develop after 2 a.m., reducing visibility on U.S. 101 near Arcata and Fortuna. Drivers should allow extra time and use low beams in fog-prone areas.
Saturday and Sunday bring the sun back, though breezes will pick up. NWS forecasters expect north winds of 10 to 14 mph Saturday, with gusts reaching 20 mph. Afternoon highs should climb into the low 60s, while coastal valleys dip into the upper 40s at night. Utility crews do not anticipate major outages, but light outdoor items should be secured.
