| Area Forecast Discussion National Weather Service Eureka CA 147pm PST Tuesday Feb 3 2026 Synopsis Dry weather continues through at least Friday. Unseasonably warm afternoons and chilly mornings are likely through Thursday. Rain and high elevation snow likely returns this weekend. High pressure continues to build over the area. Offshore flow is promoting dry conditions and keeping skies mostly clear. Temperatures have already reached the 60s along the coast early this afternoon. High temperatures in the 70s are likely in the warmest valleys, including Ukiah and Lake County, and a few higher elevation areas, including Kneeland. Tonight, the same valleys seeing clouds and fog are likely to see it again, though it might be less expansive than previous nigheights with more dry air in the area. Lower dewpoints are likely to bring similarly chilly temperatures in the 20s or 30s for much of the area. Coastal stratus will likely remain offshore as offshore flow brings dry air. Despite the chilly morning, another warm day is likely Wednesday, and likely the warmest day. NBM is showing low chances for any record-breaking temperatures across the area with the highest, at 15%, being in Ukiah where the record is 78. Even coastal areas could see 60s or even low 70s. Kneeland, with sustained offshore flow, could exceed 80 degrees. Temperatures are forecast to be similar Wednesday night and Thursday with another chilly morning and another warm afternoon. High temperatures will be similar, if not a few degrees cooler. Agreement is growing on the ridging pattern ending Friday and deep, elongated trough moving through the area. Increased cloud cover and more moderated temperatures with a deep marine layer are the main impacts, at first, Friday and most of Saturday. Rain arrives sometime between Saturday night or Sunday morning. Generally rainfall amounts are likely to be minor and light. NBM is showing around a 30 to 50% chance for over an inch of rain from Sunday morning to Tuesday morning. Higher elevations in Humboldt and Del Norte have over an 80% chance for 1 inch, and around a 30% probability for 2 inches. There is still around a 20 to 30% chance that southern Mendocino and Lake sees no precipitation. Low end precipitation amounts are around 0.25 to 0.50 inches in Del Norte, Humboldt, and Trinity Counties with less than a tenth south of Cape Mendocino. High end amounts around around 1 to 2 inches north of Cape Mendocino and a half inch to an inch south of Cape Mendocino. Winds do not currently look to be very impactful, with only a 10 to 20% chance for southerly wind gusts greater than 40 mph. Though there are higher probabilities for winds gusts greater than 30 mph, especially in wind prone areas. Snow levels are also likely to remain above 5,000 ft until Sunday night, though could drop to 3,000 to 4,000 ft Monday morning, bringing light snow to the highest passes on Highway 3 and Highway 36. Uncertainty grows going into early to mid next week. Some ensemble members are showing a break in precipitation, while others are showing continued pulses of precipitation. Deep troughing will bring much colder temperatures, and if there is more precipitation, more lower elevation snow. The colder scenarios have snow levels as low as 2,000 to 3,000 ft. Uncertainty is very high with low end precipitation amounts of 0 and high end amounts of 1 to 2 inches. Stay tuned. JB Marine Westerly swells will continue to subside through the rest of today. High pressure over the region will keep winds light across the coastal waters today and again on Wednesday. The next westerly swell will build into the waters late Wednesday and continue into Friday, allowing seas to build back to around 10 feet. There is potential for this swell to build to about 11-12 ft at 16 seconds by Friday. .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... None.
