Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
moderate to fresh northwesterly winds continue through the middle of the work week before diminishing to gentle to moderate beginning Wednesday. Occasional near gale force to gale force gusts are possible across portions of the northern outer waters overnight Monday into Tuesday morning. Winds will become more west to southwesterly and gusts are expected to strengthen across the northern outer waters heading into the late week and weekend. Overcast conditions and widespread stratus continue across the coastal waters as surface high pressure builds. Significant wave heights across the central and northern outer waters will build to 10-14 feet by mid- week before seas diminish by late week.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 242 PM PDT Mon May 13 2024
SYNOPSIS
After the passage of a trough, temperatures will begin trending much higher through late in the week as a strong ridge of high pressure builds back in, bringing much above normal temperatures. Temperatures along the coast will continue to be suppressed by persistent stratus through today but will see warming as well. Strengthening northerly winds will create breezy conditions this week.
DISCUSSION
Afternoon mid-level water vapor imagery reveals a broad, weak cyclonic circulation off the CA coast around an upper low, and a subtle frontal boundary pushing southward through N CA ahead of a passing shortwave trough. Despite the slight increase in mid level moisture, subsidence will increase behind the passing trough during peak heating and this will suppress chances for isolated showers for the mountains of Trinity County today. From a 25% forecast yesterday, SREF chances for thunder have whittled down to 5% in east Trinity today. Cumulus over far SE Trinity is making good effort to break the cap this afternoon. Visible satellite exposed a vast expanse of stratus, including locked in over portions of the coast. The observed upper-low will slide into S CA on Wednesday and will influence the pressure gradient against the ridge, increasing the N to NE winds. Northerly winds are already on the increase and will be gusty along northerly exposed portions of the coast in the afternoons this week.
Warming is underway, and will continue as the expansive ridge of high pressure strengthens into mid week. This will bring another early dip into summer-like conditions, with temperatures warming to 10 to 15 degrees above average, especially on Wednesday. The mid to some upper 90s for the inland valleys will create a Moderate heat risk. Regarding coastal temperatures, this setup is not as favorable as the last warming that included deep-layered offshore flow. There is also the question of low-level cloud cover, with indications of southerly return flow south of Cape Mendocinco and the potential for a weak stratus (and potential fog) push near or around the cape Wednesday. The offshore flow will be most pronounced in Del Norte County. Temperatures will begin a moderating trend late in the week as broad trough to the north deamplifies the ridge. JJW
AVIATION
LIFR and IFR ceilings have been slowly diminishing this afternoon. MVFR to VFR conditions are expected for mostly CEC as northerlies increase, scouring out the stratus this afternoon and evening. Northerlies will force cool-damp marine air and low clouds into the Humbodlt Bay area and Eel delta, however. Thus, expect stratus to quickly redevelop around and over KACV while CEC remains VFR longer before LIFR returns overnight. HRRR indicates robust NE flow aloft over Del Norte County tonight which may suppress the marine layer and keep the stratus out of CEC. On the other hand, CLIPEREX model and statistically derived guidance indicates stratus building back over CEC. UKI is forecast to remain VFR through the period, though a few low clouds from Sonoma County may creep in around daybreak Tue, but that is not likely. DB
MARINE
Northerlies are forecast to strengthen tonight through Tuesday with the strongest winds in the outer waters. A full gale is expected for the northern outer waters (PZZ470) Tuesday with combined seas approaching 20 ft by late Tue night. Closer to shore northerly winds are expected to remain below gale except for localized regions of gale gusts, like around Pt St George and Cape Mendocino during the afternoons and evenings. Primary hazard for inners (450) will be very steep northerly waves propagating inside 10NM, mainly north of Cape Mendo Tuesday night and Wednesday morning.
The mean sea level surface pressure pattern generating these strong northerly winds is forecast to persist for the remainder of the week.
GALE FORCE WINDS in the northern outers are highly probable with large steep northerly wave propagating downstream into PZZ475 through the end of the week and perhaps into next weekend.
Now closer to shore, winds are generally forecast to remain much more subdued with the usual wind prone points like Pt St George and Cape Mendo gusting to 30-40kt. Winds may even start to shift to southerly nearshore along the Mendocino coast or south of Shelter Cove as early as Tuesday. Otherwise, small NW and S swells are forecast to move through the waters during the week. Seas will remain dominated by short-period northerly waves generated from gale or near northerly wind cores in the outer waters. DB
