| Area Forecast Discussion National Weather Service Eureka CA 252pm PST Wednesday Jan 21 2026 Synopsis Dry weather and above normal daytime temperatures will continue through the early next week. Overnight and morning temperatures will remain chilly with patchy dense fog along the river valleys and around Humboldt Bay. Chance of precipitation increase by mid next week. Partly to mostly cloudy skies are observed across NW California this afternoon, with mid- to high-level clouds streaming northward. This moisture is associated with a cut-off low approximately 330 miles off the Central California, which continues to track southward. High pressure will rebuild in the wake of this low tonight through Friday, leading to drier offshore flow. This will promote improved sky conditions on Thursday, with clear skies across much NW California Friday and into the weekend. A dry offshore flow will most likely reinforce chilly overnight lows, bringing a chance of near-freezing or freezing temperatures to coastal areas and adjacent valleys Friday night into Saturday morning. Granted places where winds stay up all night, temperatures probably will not even fall below 50F. Lower dewpoints, clear skies and light winds at night will allow for ideal long wave cooling again. Freezing or near-freezing temperatures are probable Friday and Saturday morning, both along the coast and in the wind- sheltered coastal valleys. Sub-freezing temperatures are a sure thing in interior valleys, especially Trinity and northern Mendocino. Dry weather is expected to persist through the weekend and into early next week as the high pressure persist over the Eastern Pacific, though the ridge weaken. A weak shortwave trough will bring increasing cloudiness Saturday night and Sunday. Coastal stratus are anticipated to redevelop, with a slightly deeper marine layer along the North Coast. Aside of some patchy coastal drizzle, generally dry conditions and above normal daytime temperatures are expected to continue through the early next week. Long-range models continue to suggest an increasing chance of precipitation from mid- to late next week. Uncertainties remain high in the details. Stay tuned for updates as the timing of this shift become clearer. /ZVS Marine Northerly winds will increase slightly tonight as a weak low approaches the central and southern California coast while high pressure noses toward the Pac NW coast. Surface wind fields do not appear strong enough to warrant an advisory for small craft tonight with gusts up to 18-22 kt and short period waves 5 ft or less for the outer waters. Northerly pressure gradients tighten on Thu as a mid level shortwave trough in NW flow aloft moves across the Pac NW. High resolution ensemble guidance indicates high chances for gusts to 25-30 kt (80% chance or more) with gale gusts over 34 kt much more probable (>60% chance) for the northern portion of pzz470 by 4 to 8pm Thursday. Gale gust coverage increases after 8-10PM with very steep seas building to 9-11 ft overnight into Friday. Thus the watch for gales has been upgraded to warning as combined seas build to 12 to 15 feet in the outer waters by Fri afternoon. Ocean conditions will also deteriorate Thu night and Friday for the inner waters. Gale gusts are certainly probable around notorious wind prone locations such as Cape Mendocino and perhaps around Pt St George. Primary hazard for the waters appears to be large steep waves arising from the strong northerlies offshore. Confidence seas will be sufficiently elevated and very steep for a warning across the inner waters is not high. Perhaps buoys on the outer fringes of the inner waters will be report warning criteria. For now, a small craft advisory will be sufficient to let mariners in small craft know about deteriorating marine conditions and plan accordingly. Now conditions look to gradually improve over the weekend as the axis of strong north wind shifts outside of NW California waters and steep wind waves gradually subside. In this mix of steep short period waves will be a long period (>16 seconds) westerly swell on Thu that will decay through Fri. A mid period swell near 14 second follow on Fri, followed by third mid period group on Sat. None of these appear to pose a risk for sneaker waves at this time. .EKA WATCHES/WARNINGS/ADVISORIES...
