Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
a strengthening low pressure system over the eastern pacific will continue moving toward california resulting in southerly gales and moderate to heavy rain developing today. Cold, unstable air aloft with the low will also result in a slight chance to chance of Thunderstorms later today, tonight and Saturday. A high pressure system will build in behind the low late in the weekend and early next week bringing drier, milder conditions to the area.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 325 PM PDT Thu Mar 28 2024
SYNOPSIS
Showers activity will continue to wind down this afternoon and evening. A second round of wind and gusty showers will hit the southern half of the area on Friday with cool and clearing conditions through the weekend.
DISCUSSION
Post-frontal scattered showers and isolated thunderstorms continue moving east-northeast across the area this afternoon, especially over areas farther north of Mendocino County. Snowfall amounts as of 3500 feet have been very light feet on highway 36 this afternoon. Showers activity are expected to wind down late this afternoon and evening.
IR satellite imagery depicts an amplifying upper level trough/deepening cutoff low stalled over the NEPAC this afternoon, while a secondary and stronger Pacific Storm rotate around the cutoff. This secondary low system will continue to move southward and quickly strengthen as approaches the California Coast Friday afternoon, absorbing the current cutoff low. Showers will begin to increase in coverage Friday morning becoming stratiform precipitation Friday afternoon along the warm sector of the low. Moderate to locally heavy periods of rainfall is forecast for the southern portion of the CWA Friday afternoon and evening. While light precipitation is expected for the rest of the forecast area. Additional rainfall ranging from 0.3 to 1 inch is most likely from this system, with heavier amounts farther southern portion of Mendocino and Lake County. Wind turning east through the event will generally focus rain along higher terrain and rain shadow lower elevation areas such as Clear Lake itself.
Increasing east-southeast winds are expected Friday afternoon and evening, mainly focused over Mendocino and Lake counties. Gusts from 30 to around 40 mph are are expected over the coastal headland and exposed ridges as result. However, with the easterly winds may aid in funneling gusty winds in Lake County.
The National Blend of Models (NBM) 90-95th percentile (high end)
indicates gusts around 45mph in Lake County, with strongest winds over the higher elevation. Continued evaluation is needed for Wind Advisory criteria. /ZVS
LONG TERM
(FROM PREVIOUS DISCUSSION) 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
Post-frontal, on-going showers have continued to have lingering impacts at the Taf sites today. CEC to experience gusty surface winds today plus VCTS in the mid-late morning. Cig/Vis generally remained VFR. ACV continued with breezy winds and occasional bouts of MVFR from mid-late morning. UKI, through early afternoon, remained a little "Topsy-Turvy" as numerous showers moved across the terminal. Conditions briefly dropped into IFR. Basically, shower activity will taper through the evening...especially north of Cape Mendocino. Offshore, another low pressure system, and associated frontal boundaries, will dip south and have a greater impact over Mendocino and UKI Friday morning; lowering Cig/Vis can be expected with substantial precipitation. /TA
MARINE
A steep mid-period swell peaked this afternoon around 15 feet at 14 to 15 seconds. Combined with southerly wind wave energy, significant wave heights reached 18-19 feet. Winds and seas will diminish overnight before a shortwave drives a progressive surface low south along the CA coast. The trajectory of this low will dictate the enhancement and orientation of winds heading into the weekend. Winds will turn southeasterly and increase in the southern waters early Friday afternoon, likely generating a brief period of gale gusts in the outer waters. Winds will gradually turn to the east/northeast Friday night into Saturday as the low dips south of Point Arena, with wave heights persisting at 8-10 feet throughout. A tightening pressure gradient between the northeast quadrant of the low and an offshore ridge building into the waters will gradually generate increasing northerly winds on Saturday. Saturday night into Sunday holds the greatest chance of gale or potentially storm force gusts, beginning in the northern waters and extending south. Wind waves are expected to respond quickly with wave heights 15-17 feet possible early Sunday morning. Winds and seas will likely remain elevated through the weekend before a reprieve to start next week.
