AREA FORECAST DISCUSSION National Weather Service Eureka CA 252 PM PDT Tue Oct 3 2023

SYNOPSIS
Drizzle and low clouds along the coast will quickly clear this evening as dry offshore winds develop across northern California. In addition, offshore winds will aid in the development of warm temperatures through much of the remaining work week. A cooling trend is then expected this weekend, and wet weather will likely return early next week.

DISCUSSION
A prominent upper-level ridge was positioned over the NERN PAC this afternoon, with northerly midlevel flow present across the West Coast. A cold/dense low-level airmass will spread south beneath the eastern periphery of the ridge tonight and aid in the initiation of offshore-directed winds. Peak gusts to 30 mph are expected across many ridges during Wednesday morning, with locally higher gusts possible in the lee of north-south oriented ridges due to possible mountain wave development. Otherwise, the easterly low-level winds will favor warming temperatures that will lead to highs ranging from around 70 at the coast to the 80s/90s across inland valleys Wednesday and Thursday afternoon.

The previously mentioned ridge over the NERN PAC is forecast to break down over the weekend. Falling midlevel heights will aid in a cooling trend across NRN CA, and also support increasing precipitation potential. Precip may initially arrive in the form of coastal drizzle in the vicinity of Humboldt/Del Norte Counties Saturday and Sunday. That will be followed by a frontal rain band moving east across the region early next week.

AVIATION
North winds will continue to increase and become gusty throughout the region with gusts to 30 mph possible, particularly around Crescent City. The stronger winds and gusts will generally occur along the coast and at higher elevations through this evening. Late this evening as winds die down at the surface, winds aloft will remain elevated, especially around the Del Norte Coast. This will make low level wind shear a concern as surface level winds decrease. Offshore flow overnight tonight should keep coastal stratus at bay along the coast, but trapped moist air in coastal river valleys and interior valleys may cause some patchy fog into tomorrow morning. This means mostly VFR for the area and potentially IFR ceilings for those valleys mentioned.

MARINE
Gale force northerly winds are expected for mostly the outer waters this afternoon and through tonight as high pressure strengthens offshore. A few gale gusts may occur closer to shore near Pt St George and downwind of Cape Mendocino, but areal coverage is well below 50%. Gale force winds are forecast to persist north of Cape Mendocino through tomorrow evening, mainly in the outer waters and around Point St. George. Gale force gusts in the Northern outer waters are expected to diminish in coverage early tomorrow morning, but then expand by the afternoon and evening. Seas will be borderline for a hazardous seas warning north of Cape Mendocino tonight, with wind waves around 10 feet at 8 seconds across the outer fringes of the northern inner waters.
For areas south of Cape Mendocino, wind conditions are forecast to ease up tomorrow, though seas will remain elevated. As a result, a hazardous seas warning has been issued with sufficient coverage of the zone but marginal wave heights. Northerly winds and steep waves will diminish into Thursday for much of the area and then remain light and variable Friday through Saturday. Steep northerly waves will probably remain sufficiently elevated on Thursday for the northern outer waters. NW swell is forecast to peak near 6 feet today and then steadily subside for the remainder of the week.

FIRE WEATHER
Low-level cold air advection developing south across the Great Basin and adjacent NRN CA will force the occurrence of offshore winds tonight. Ridges will become gusty as a result, with peak gusts averaging around 30 mph. In addition, locally higher gusts will be possible in the lee of north-south oriented ridges due to mountain wave development. However, relative humidity values will be marginal, with overnight values ranging from 40-60 percent, and daytime values in the 20-30 percent range. The marginal dryness will preclude the issuance of a fire weather watch/red flag warning.
