| Area Forecast Discussion National Weather Service Eureka CA 1231am PDT Thu Oct 30 2025 Synopsis General high pressure continues over the area creating a dry weather pattern for the remainder of the work week. Warmer than average temperatures are likely for the interior, while there's also a potential for overnight chilly temperatures in the coldest interior valleys. Chance for rain this weekend and mid next week. High pressure continues over northwestern California this week. Warmer than average maximum temperatures are forecast for the interior through the week as high pressure continues with mostly clear skies. For interior valleys that remain cloud free overnight, radiational cooling could bring chilly early morning temperatures, especially for the colder interior valleys. However, for the rest of the week, overnight temperatures should still remain above the threshold for frost to develop. Despite the chilly mornings through the end of the work week, high temperatures are forecast to be mostly in the mid 70s with some of the warmest valleys possibly near 80. Average temperatures are expected along the coast with coastal stratus expected overnight each day into the weekend. High clouds are expected to move over the area Thursday. Ridging is forecast to weaken later in the week and into the weekend as a series of troughs approach the Pacific Northwest. Confidence is low on if any of these troughs will reach far enough south to bring us precipitation. The placement of the trough currently far to the northwest of our region will determine if we receive rain early this weekend. Models are still not in agreement with NBM probabilities of greater than 0.1 inch of precipitation over a 6 hour period decreasing for our area early Saturday with the latest model run. Ensemble clusters are fairly confident in keeping us with above normal 500 mb heigheights through the weekend. The CPC 8 to 14 day precipitation outlook highligheights northwestern California for above normal precipitation and the NBM and Global Models are starting to align to agree with this as well. Marine Northerly winds have picked up this afternoon to around 15 to 20 kt offshore and slightly lower near the coast. This is building wind driven seas to around 7 to 10 feet. A new northwest swell has also started to build into the waters. Initially this is around 18 seconds at 3 feet. This is combining with the current swell which is around 5 feet at 10 seconds. This new swell continues to build and is expected to combine with the old swell for around 8 to 9 feet at 14 seconds tonight. Thursday the winds remain fresh to strong, with the strongest winds in the southern outer waters. Thursday night and Friday a frontal boundary is approaching the area and the winds are expected to shift to southerly. These are expected to start becoming southerly in northern waters Friday morning, but not make it all the way to the southern waters. Saturday afternoon this frontal boundary is expected to move past the area and high pressure builds back into the area and rapidly strengthens the northerly winds. Northerly winds persist through Sunday night. Monday another weather system is expected to bring more widespread and stronger southerly winds. The next notable swell is expected to move into the area on Saturday. This is initially expected to quickly build to 4 to 6 feet at 18 seconds. Saturday evening and overnight this combines with the current swell and builds to around 13 feet at 16 seconds. MKK .BEACH HAZARDS...Currently there is a long period swell building in and it is around 3 feet at 17 seconds. This is expected to quickly drop to 14 seconds and combine with the existing swell therefor limiting the sneaker wave potential. The next notable swell is expected to arrive on Saturday. This could pose a sneaker wave threat. Initially wave periods are expected to be around 20 seconds with waves building to around 4 to 6 feet at 18 seconds. Winds will still be southerly and fairly light. So expect we will need to highlight this as it gets closer. MKK .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... Small Craft Advisory until 5am PDT Thursday for PZZ450-455. Small Craft Advisory until 10pm PDT Thursday for PZZ470. Small Craft Advisory until 4am PDT Friday for PZZ475.
