Marine Weather and Tide Forecast for Little River, CA

FXUS66 KEKA 090733 AFDEKA

AREA FORECAST DISCUSSION National Weather Service Eureka CA 1233 AM PDT Sat May 9 2026

SYNOPSIS...Temperatures will slowly warm for the interior into the weekend. Coastal clouds may limit sunshine and warmer temperatures for the coast through the weekend, with chances for fog.

KEY MESSAGES...

-High pressure building into the weekend will warm interior temperatures. High temperatures will peak Monday with minor to moderate heat risk for interior valleys.

-Cooler temperatures and slight thunderstorm potential late next week.

DISCUSSION...Weak high pressure has started to spread over the area today. This has enabled slight warming int he interior with some highs breaking above 80. Meanwhile, a still strong but shallowing and drying marine inversion has allowed for gradually clearer scattering skies along the coast, with Humboldt Bay currently the last refuge of clouds. Similar conditions will continue into the weekend. Marine influence will be strongest in the sheltered areas of Humboldt Bay, with more reliable day time clearing elsewhere.
Moderate north wind will push on to shore each afternoon this evening and may help mix some low clouds away.

High pressure will continue to build through Sunday and into early next week. High temperatures will most likely peak around Next Monday. Interior highs will most likely reach the low to mid 90s.
Solidly above average temperatures will promote generally minor to moderate Heat Risk with the greatest risk in Lake County due to warm conditions continuing overnight. A shallow marine layer along shore will likely make for more scattered skies in the afternoon. Should skies clear enough, coastal temperatures could reach into the mid 60s on Monday.

Most model ensemble members show a cutoff low forming up along shore mid to late next week. This low will help slightly weaken high pressure and drop interior temperatures. This low could bring a threat of thunderstorms, but most models show it staying too dry and too far offshore to bring much risk. Most thunderstorm potential late next week is no more than 10% at the moment in most models.

Building high pressure is contributing to lower ceilings and visibility for the coastal terminals. LIFR ceilings are forecast to take hold, with a low chance for fog (10-20%). Similar conditions are possible at CEC. Though ceilings are shallow, latest guidance resolves a southerly return eddy to form and remain present into Saturday afternoon. This pattern favors stratus to remain locked to the coast longer than modeled.
There is some question as to how much lifting can occur through the afternoon hours. Probabilities for IFR levels to remain at ACV only lower to 40% through the afternoon, with a 20-30% chance for at least TEMPO LIFR ceilings throughout the day. That said, confidence is currently low on the flight categories through the afternoon hours, which may include some full scattering. If scattering does occur, the stratus should quickly fill back in through the evening hours to IFR and potentially LIFR levels.
Farther south through UKI, conditions are forecast to remain VFR with light winds that occasionally gust from the NW up to 18kts through the afternoon.

MARINE...Northerly winds will trend stronger Saturday afternoon, particularly south of Cape Mendocino where near gale to gale conditions will be likely. Northerly winds will further strengthen in all zones Sunday afternoon, up to 25 kts through Sunday night. Winds will ease throughout the day Monday, but the steep seas of 6 to 9 ft will take longer to subside into Tuesday morning. Thereafter an extended hiatus in northerly winds may last into mid next week, with no sizable swells of interest.
