| Area Forecast Discussion National Weather Service Eureka CA 149am PDT Monday Mar 16 2026 Synopsis A warming trend is expected to continue through the end of the work week. Increasing heat across the interior, with interior widespread Minor HeatRisk. Expect unseasonable, very warm temperatures across all of NW California with a chance of record breaking heat for inland areas of Mendocino County. Strong high pressure over the Pacific will build into the region promoting dry weather and above-seasonably temperatures across NW California. Despite some high level clouds streaming around the northern periphery of the ridge, there should be enough radiational cooling to facilitate the formation of low clouds and patchy fog around the Humboldt Bay and vicinity. There is very high forecast confidence that ridging will remain dominant over the western CONUS through the work week, continuing to promote dry weather and warming trend pattern. High temperatures will warm to around 10-20F above the seasonal average across the interior through Friday. By mid week, the high pressure will stall over the desert southwest. This will force offshore, easterly winds that will reinforce the anomalous temps Thursday and Friday. NBM shows the probability for high temperatures exceeding 90F around Ukiah at 50% on Tuesday, diminishing to 20-25% Wednesday and Thursday, before increasing again to 50% on Friday. Even higher percentages are displayed for SE Lake County through this week for temperatures over 90F. Expect a widespread Minor HeatRisk across the interior. The heat will primarily impact those who are extremely sensitive to heat and those without cooling or hydration available. Even the coastal areas are expected to warm up to mid to upper 60s this week before afternoon seas breezes develop. Over the weekend, medium range forecast models show the ridge beginning to weaken and shift eastward. That said, confidence remains high in a continuation of dry weather through the weekend. DS Marine Monday the northerly winds are expected to persist around 10 to 20 kt with the strongest winds south of Cape Mendocino and especially just downwind of the Cape. There may be some local gusts to 30kt just downwind of Cape Mendocino. Monday a southerly swell is also expected to build into the waters. Initially it looks like it will be around 2 feet at 18 seconds. It looks it may peak near 3 feet at 16 seconds Tuesday afternoon and overnight. On Tuesday a northwest swell is expected to build to around 4 t 6 feet at 14 seconds Tuesday night and persist into Wednesday. This will then gradually diminish. Monday night and Tuesday the winds continue to diminish to around 5 to 15 kt with the strongest wind still just south of Cape Mendocino. Fairly light winds are expected to continue Wednesday and Thursday. Friday the models are showing the northerly winds increase through the day. Friday night and Saturday the winds increase to gales and may persist into Sunday. MKK .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS...
