Synopsis for northern california waters - A mid-period northwest swell peaks this morning as short period wind waves reinforce the sea state. These will combine to produce seas of 15 to 18 feet today. The small craft advisory is extended into Friday afternoon/evening as the swell decays. A closed low will drop down along the california coast Friday evening into Saturday with the potential to generate brief se gale gusts in the southern outer waters. Saturday evening has solid potential for northerly gales and hazardous seas in the outer waters (especially north), possibly pushing storm force, but this will highly depend on placement and timing of the low as it heads south. A long period northwest swell will build in for Monday, generated from the current low pressure system headed toward the gulf of alaska.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 309 AM PDT Thu Mar 28 2024
SYNOPSIS
Showers will gradually weaken through the day today. A second round of wind and gusty showers will hit the southern half of the area tomorrow with cool and clearing conditions through the weekend.
DISCUSSION
Showers and some isolated thunderstorms have continued to move onshore through the early morning hours. These showers have continued to drop mostly light rain with very light snow observed as low as 3500 feet along Highway 36. Convective allowing models consistently show another couple lines of showers crossing the area this morning and then progressively dwindling through the afternoon.
0.5 to 1.0 inches of additional rainfall is most likely through noon today, mostly restricted to Humboldt and Del Norte Counties. Current observations suggest snow levels just below 4000 feet along Highways 299 and 36. Further QPF this morning could translate to between 2 to 4 inches of wet snowfall on the very highest highway passes, particularly on the western portions of 36.
As showers dwindle later this afternoon, a secondary, parasitic low pressure system is expected to rotate around the cutoff low currently stalled off the coast of Oregon. This low will quickly strengthen and sweep south down along the coast. Small changes in the track of this low will substantially effect the forecast, but an increase of wind, mostly focused in Mendocino and Lake Counties is certain Friday. Winds will begin south and then shift east as the low progresses. The strongest gusts are most likely over the ridges of Mendocino and Lake Counties Friday afternoon with peak speeds of 40 to 50 mph. Chances of 45 mph wind gusts at Lake level remain low between 10 and 20%. A second round of rain showers will accompany the winds with 0.5 to 1.0 inches of rain most likely. Wind turning east through the event will generally focus rain along higher terrain and rain shadow lower elevation areas such as Clear Lake itself.
Cold air will advect alongside the low as it travels south, brining chilly nights in the 40s through the weekend. That said, stubbornly cloudy skies will inhibit widespread frost and valley fog formation until at least Sunday morning, when the coldest and clearest conditions are most likely. As the low moves east, it will help enhance the pressure gradient with high pressure building over the east Pacific. This will allow for strong northerly wind right along shore and just offshore Sunday into early next week. Thanks to the wind's consistency, NBM already show high confidence in northerly wind gusts of 25 to 35 mph hitting shore Sunday. That said, generally stable conditions and weak winds aloft (associated with the high pressure) will most likely inhibit any wind advisory level gusts (45 mph).
Model ensembles show high confidence (80%) of at least a couple days of high pressure dominated warm and clear days early next week with strong onshore flow in exposed areas. There is much more divergence by mid next week, however. Most (80%) of cluster ensemble members show a trough moving onshore sometime between next Wednesday and Friday, but the exact strength and impact of the trough varies widely. Only about 30% of ensemble members show the trough produce impactful rain and wind. (more than 1 inch and gusts over 45 mph)
/JHW
AVIATION
The biggest issue in the short term will be handling the variable ceilings and visibilities this morning into the early afternoon as showers and isolated thundershowers will be hit or miss. By late Thursday night a warm front/occluded front approaches from the west, shifting wind direction to the south southeast as a more solid shield of rain develops, and wind speeds increase by late Friday morning, especially for KUKI and points south.
MARINE
Combined seas of 16 to 18 feet build in today. A mid-period northwest swell continues to slowly decreases in period and increases in height over time as short period wind waves continue from the southwest and will decay by tonight/Friday morning. For wind direction, this can be essentially divided into three time sections due to the movement of the surface low heading south off the west coast. A perturbation from the west northwest will combine with the current low over the northeast Pacific and form a short- lived Fujiwhara type situation Thursday night into Friday morning.
The current wind direction is primarily southwest behind a cold front, but will shift to the southeast on Friday as the surface low(s) head south. The small craft advisory will likely need to be extended into Friday afternoon thanks to the forecast northwest swell, with southern outers holding on maybe into Friday evening a little longer thanks to the remnants of the short period waves from the south. By Friday night, most areas will develop a north component as the feature combines the lows into one closed low and continues south. The wind could become quite strong in this wrap around "back side" region of the low by Saturday evening, potentially giving us the strongest wind/wind gusts for the next seven days according to ensemble data. At this time, Saturday evening has solid potential for gales and hazardous seas in the outer waters (especially north), possibly pushing storm force, but this will highly depend on placement and timing of the closed low as it heads south. A long period northwest swell will build in for Monday, generated from the current low pressure system headed toward the Gulf of Alaska.
