Afternoon fresh to locally strong northerlies are expected south of cape mendocino on Wednesday, before fresh breeze spread across the outer waters early Thursday in the wake of a weak shortwave. NEarshore are expected to continue light to gentle breezes. Steep short period seas will continue to promote hazardous conditions for small craft primarily in the outer zones for the rest of the week.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 421 AM PDT Tue Jun 18 2024
SYNOPSIS
Dry weather is expected for the foreseeable future.
Interior temperatures begin a slow warming trend through the work week with temperatures approaching 100 degrees in some interior valley locations Friday into Saturday.
DISCUSSION
Dry conditions are expected to persist for the next week as dry air remains in place within the mid-levels of the atmosphere over Northwest California. Troughing the next couple days will keep temperatures over the interior near normal through Wednesday. By Thursday the trough will begin to break down and 850 mb temperatures will warm across the interior allowing some interior valleys to approach 100 degrees Friday into Saturday. All while this is occurring, northerly winds and increasing low-level moisture at the coast will result in increasing chances of coastal stratus through the week with temperatures remaining near normal at coastal sites.
Temperatures will moderate a few degrees across the interior over the weekend into early next week but still remain several degrees above normal.
AVIATION
Like early yesterday morning, extensive coastal stratus is unlikely to form into this morning, however; unlike early yesterday morning, slightly more stratus is expected to form. As of now, low clouds are forming around Humboldt Bay and down the Eel River Valley creating MVFR to IFR conditions. Brief periods of coastal stratus may be likely along the Del Norte coast due to calm wind conditions into early this morning. Winds will not be as strong at the terminals today, but by late morning to early afternoon northwesterly to westerly winds are forecast to pick back up. Gusts will be strongest for Mendocino and Lake counties and along the Del Norte Coast with high resolution models indicating gusts to 20 knots. Chances for stratus increase tonight along the coast with a high pressure system building into the region through the rest of the week. /JLW
MARINE
Northerly winds have decreased from yesterday, but will remain in small craft criteria for all zones into mid morning. Winds will pull away from the coast north of Cape Mendocino by mid to late morning ending the small craft advisory for the northern inner zone.
Each afternoon there will be a slight uptick in northerlies with the highest winds (still below gale conditions) occurring in the lee of Cape Mendocino. Coverage for the expansion fan will be sufficient to keep a small craft advisory in the southern outer waters through the middle of the week; however, by Wednesday afternoon only a small portion of the southern inner waters, just south of the Cape, will have small craft winds. Due to this, the small craft advisory for the southern inner waters will expire by Wednesday afternoon. High resolution wind models and NBM indicate that the outer zones will remain in small craft conditions through the middle/end of the week with another slight increase in winds into this weekend. Seas will remain steep through the week due to the winds, especially in the outer waters. Two to three foot, long period westerly and southwesterly swells will continue through the waters into the end of the week. /JLW
