Synopsis for northern california waters - Dense marine fog is currently hugging close to the coast and should persist throughout the night. Northerly winds and seas have begun to increase late this afternoon as a high pressure gradient builds along the coast, with northerly gales expected in the outer waters by late tomorrow. 14 to 16 foot steep seas are possible through mid- week, with the highest wave heights gradually shifting to the northern outer waters alongside the highest wind gusts Wednesday and Thursday.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 319 PM PDT Sun May 12 2024

SYNOPSIS
After brief moderation from a passing trough today, temperatures will begin trending higher through late next week as a strong ridge of high pressure builds back in. Temperatures along the coast will continue to be suppressed by persistent stratus through Monday. Strengthening northerly winds will create breezy conditions next week.



DISCUSSION
Afternoon visible satellite reveals abundant stratus along and over portions of the coast, with cumulus clouds popping up over interior Trinity County. There will be a slight chance for a thunderstorm this afternoon over far eastern Trinity County. A shortwave trough is passing through the region, and has been responsible for weakening the persistent ridge. This will only be short-lived as the Pacific ridge will quickly amplify in the departure of the trough. The cumulus growth this afternoon is yet to break the cap, but a stray shower of perhaps a thunderstorm may develop over E Trinity County into the evening. The passing trough will deliver a weak frontal boundary which may act to further enhance forcing over the Yolla Bolly areas and into N Trinity tomorrow afternoon for another shot of isolated showers or a thunderstorm; however, available moisture is in question.

Northerly winds will begin increasing on Monday afternoon. The exposed coastal spots will see some gusts from 20 to 30 mph in the afternoons, with stronger gusts in coastal Del Norte. As the ridge strengthens Tuesday, a weak upper low will move into S CA. Similarly as was seen over the last several days, the combination of features will create above normal temperatures, including warm advection to the coast from offshore winds. Inland temperatures in the valleys do look to to be warmer than what was recently observed, with widespread low to mid 90s.

AVIATION
IFR coastal stratus capping a deep marine layer is expected to break out a bit this afternoon with strong diurnal heating and northerly winds offshore. ACV is most likely to experience MVFR scattering this afternoon while a persistent eddy south of Pt Saint George maintains the stratus deck in CEC, although brief breaks are possible. Otherwise, visibilities should remain mostly clear through early evening even beneath <1000 ft ceilings.
Deeper inland extent and lowering of marine stratus is expected to resume around sunset, likely reducing visibilities and ceilings back to IFR conditions at the coast overnight. Northerly winds will rapidly increase offshore Monday afternoon as the coastal pressure gradient tightens, helping disperse coastal stratus as high pressure builds into the region.



MARINE
Satellite data beginning to indicate the development of expansion fans cutting through the marine stratus layer downwind of southern Oregon and Cape Mendocino. Northerly winds will gradually increase to small craft criteria in the outer waters overnight into Monday, initiating wind wave responses to 10-12 feet. Gales and steep seas are expected to rapidly develop Monday evening through Tuesday, with gusts exceeding 40 knots through late this week. As 30- 40 knot gusts shift to the northern outer waters late Tuesday into Wednesday, wave heights are forecasted to reach and potentially exceed 17 feet. With seas largely driven by local winds, the southern waters are expected to drop below gales by midweek wile the inner waters maintain some geographic shielding.
