| Area Forecast Discussion National Weather Service Eureka CA 129pm PDT Wednesday Mar 11 2026 Synopsis Slightly warmer conditions expected today and tonight. Coastal drizzle is possible tonight and again Saturday for Humboldt and Del Norte. More significant warming is likely late this weekend and next week. Mostly clear skies, light winds, and slightly warmer interior high temperatures are forecast for the area today. A weak system will clip the area tonight bringing increasing high clouds and perhaps some low clouds and drizzle to the coast early Thursday morning. Overnight low temperatures are likely to nudge upwards slightly, lowering the risk of widespread frost. Still, some areas in northern Mendocino County could see temperatures in the mid 30s. A dominant ridge of high pressure will also be building over the rest through the week. Another weak, clipping front will temporarily weaken the ridge and will bring more chances for light rainfall or drizzle late Friday and Saturday. Chances for a 0.1 inch or more of rainfall are a little higher for this system for coastal Del Norte (50-75%), but only trace amounts may be recorded elsewhere. There is high confidence the ridge will begin to greatly amplify through the end of the weekend and next week. Near record high temperatures will be possible with some of the warmest valleys in Mendocino and southern Lake possibly exceeding 90. By Sunday, NBM probabilities for high temperatures over 85 increase to around 40% for Mendocino and western Lake, and over 70% for southern Lake. On Monday chances increase to above 80% for all of southern Mendocino and Lake Counties. Chances for over 90 degrees are about 20% outside southern Lake, where chances are over 70%. Elsewhere, most interior valleys could see temperatures in the 80s, while coastal areas could see high temperatures in the high 60s to low 70s. Marine Short to mid period NW swell around 7 to 8 ft is forecast to steadily subside tonight-Fri. Long period SW swell is forecast to build to 2 ft Thu-Fri. Otherwise, steeper N-NW wind wave will continue to dominate the wave spectrum and pose the greatest hazard to small vessels. Wind waves will be borderline for an advisory south of Cape Mendo today-tonight, near 6 ft. North wind gusts from 25-30kt also appear localized downwind of Cape Mendo as well. Northerly winds and steep wind waves should increase in coverage Thu afternoon into Thu night. Coverage of seas and wind gusts > 25 kt looks sufficient to warrant an advisory for small craft. Otherwise, lighter winds and lower seas expected for the northern waters through Friday as a stalled out front meanders about north of the area, over NW Oregon. Stronger northerly winds are forecast throughout this weekend as the stalled out frontal boundary lifts out the NE and surface high pressure builds to the NW. Winds do not appear strong enough to warrant a gale watch, however local gale gusts downwind of Cape Mendocino is a common occurrence with these northerly wind patterns and is certainly possible. .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... Small Craft Advisory from 2pm Thursday to 3am PDT Friday for PZZ455. Small Craft Advisory from 2pm Thursday to 5am PDT Monday for PZZ475.
