FXUS66 KEKA 022251 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 251 PM PST Mon Feb 2 2026 .SYNOPSIS...Dry weather is expected through the work week. Warm days and chilly mornings likely for much of the area. Rain possibly returns this weekend. && .DISCUSSION...High pressure has started to rebuild over the area, bringing mostly clear skies and dry weather. Some areas of valley fog have been observed in some of the river valleys with chilly overnight conditions also being observed with low temperatures in the 20s and 30s. This pattern is likely to continue for much of this week as high pressure remains overhead. High temperatures will likely trend upwards over the week, with mid 70s possible in some of the warmest valleys mid this week. The low sun angle and colder nights will prevent some of the valleys, like most in Trinity County, from seeing as warm of temperatures, with low to mid 60s forecast. Coastal stratus will keep temperatures moderated today and perhaps tomorrow, though once stratus scatters out in the afternoon, temperatures of high 50s to low 60s are likely. Offshore flow and a shallow marine layer will likely reduce coastal stratus by mid to late week, which could bring temperatures into the mid 60s, but also chilly temperatures in the mid to high 30s overnight. Long term ensembles are suggesting the ridge finally starting to break down by the weekend. Uncertainty is high with how this will develop. NBM is showing around 50% probabilities for over an inch of rain this weekend into early next week with higher probabilities in the higher terrain. However, NBM does show about a 20% chance for Mendocino and Lake Counties to remain dry. More detail will become clearer in the coming days. Stay tuned! JB && .AVIATION...VFR conditions prevail over most terminals in Northwest California through this afternoon. Another round of low clouds for coastal terminals may be possible tonight, but light offshore flow could reduce the coastal coverage. However, interior valleys will most likely see low clouds and fog overnight. KUKI could even see visibility reductions very early Tuesday morning. && .MARINE...A westerly swell will continue to move through the waters this morning with seas above 10 feet for most locations through late this afternoon. High pressure will build over the west coast this week with light winds expected over the coastal waters. Seas will subside on Tuesday into Wednesday with conditions likely to remain below small craft. Another large westerly swell will build into the waters Thursday into Friday with heights expected to be around 11-13 feet at 15 seconds. With winds remaining light to moderate, short period seas will remain small and westerly swells should be the dominating wave through the forecast period. /RPA && .BEACH HAZARDS...A long period westerly swell train continues today with heights between 10 and 13 feet with periods near 15 seconds. This swell may be too large for sneaker waves, though it could still pose a threat to beachgoers. Breakers up to 16 feet for west and northwest facing beaches are forecast based on average beach slope profiles today. Beachgoers venturing near or in the surf zone should remain vigilant. Avoid rocks, jetties and steep beaches. Another large swell may bring slight sneaker wave threat Thursday into Friday. /RPA && .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS... Small Craft Advisory until 4 PM PST this afternoon for PZZ450-455-470-475. && $$ NOTE: The full forecast discussion is now regularly issued between 10 am/pm and 1 pm/am.
