Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
stronger northerly winds are arriving. Gale force gusts will begin to spread southward through the rest of the weekend. Expect hazardous conditions and steeper wind waves from these building winds throughout the next work week.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 445 AM PDT Sun May 19 2024

SYNOPSIS
Afternoon gusty winds will continue through midweek as the coastal jet pushes onshore. Slightly below normal temperatures expected through the week amidst a series of upper shortwaves and associated weak fronts. More substantial unsettled pattern possible late week into next weekend.



DISCUSSION
Gusty northerly winds continue just offshore as the meridional coastal pressure gradient tightens. Winds have effectively eroded the coastal stratus, leaving only the Eel River Valley, coastal Humboldt and the Russian River Valley with low level cloud cover. As a broad upper level troughing pattern dips into the PNW, temperatures will begin to trend down below seasonal norms over the next several days. Saturday's interior heating has so far mitigated frost potential across the CWA - that said, daytime highs are forecast to fall into the upper 60's and low 70's with <30% RHs across the interior today, posing greater potential for interior frost Monday morning. HRRR indicates a 30-40% probability for <36 degrees in eastern Trinity and interior Humboldt counties, although probabilities for temperatures <40 degrees are more widespread from interior Del Norte to northern Mendocino counties.

The coastal jet will continue to enhance northerly flow through mid- week as upper shortwaves progress into the Great Basin. Mid to high level cloud cover will accompany these disturbances but carry little chance for precip - the greatest chance for passing shower in Del Norte Tuesday into Wednesday is still very marginal. Cooling aloft in addition to strong winds should keep coastal stratus to a minimum through mid-week. Daily afternoon surges of northerly wind gusts 25- 35 mph are expected across coastal areas and windward ridges through Tuesday, when the wind field is likely to shift into the southern waters and further offshore. Gales have been persistent across area waters, but expected to remain below advisory criteria over land.

More persistent WNW flow is forecast by mid-week, enhancing BL moisture and allowing for potential redevelopment of the marine inversion as a transient ridge builds into the coast. Long range models indicate a more progressive troughing pattern expected for late this week into next weekend.



AVIATION
Marine stratus limited to Humboldt Bay and Eel River Valley amidst strong northerly winds offshore. MVFR ceilings expected to persist at ACV through the morning with no significant reductions in visibility as the marine layer weakens. Weak winds at CEC early this morning allowed some scattered stratus to move in, but gusty northerlies expected to resume mid-morning. Coastal terminals will likely see 20-30 knot gusts again this afternoon as the coastal jet pushes onshore. UKI remains VFR this morning as south winds are too weak to advect stratus up the Russian River Valley. A similar pattern is expected for Monday.

MARINE
A thermal trough along the coast will produce a strong pressure gradient that will persist through Monday. This will result in gale force winds and large steep waves in all waters. Current model guidance indicates the strongest winds and wave response shifting to the southern waters by Wednesday. Gales are expected to finally cease by mid next week as the coastal pressure gradient weakens.
