Synopsis for northern california waters - Northerly gales in the outer waters will continue through the weekend and into early next week as large, short- period seas persist across all zones. Winds and seas are expected to subside slightly before increasing again tomorrow afternoon with a concentration in the southern waters. Gale or near- gale force winds and hazardous seas remain likely late this weekend through early next week.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 239 PM PDT Sat May 18 2024

SYNOPSIS
Temperatures will be near normal to slightly below normal over the next week as weak fronts move through the region.
Northwesterly winds will be gusty each afternoon particularly at coastal areas and ridges as the sea breeze pushes inland.



DISCUSSION
A cloudy overcast morning quickly gave way to clearing by the afternoon and will last through to the evening as winds build. Model soundings show dry air aloft, mixing down well to the PBL and minimizing overnight fog and stratus effects for most areas overnight, except for Humboldt county. HRRR shows low cloud cover from the north and interior as well as the coast and southern Humboldt. Clearing is expected by Sunday afternoon for the CWA with some high cloud cover over Trinity and southern Humboldt early Sunday morning.

Gusty winds are building presently at the time of this forecast and expected to continue through the evening. A brief reprieve from gusty northerlies will be isolated north of the 40.5N latitude, with gusty northerlies returning Sunday evening. No wind products have been issued as thresholds on land are approaching advisory criteria or are not lasting long enough to warrant products over land. As upper level shortwaves and weak surface reflections of these shortwaves move through the region, the winds will fluctuate slightly with a stronger period of winds Sunday into the first half of the week. On land these winds will be reflected as gusty north- northwesterlies each afternoon into the early evening. Winds will be strongest along ridgelines and northwest to southeast oriented valleys and coastal headlands.

The King Range will likely remain persistently windy throughout the day and night with a more north-northeasterly orientation overnight into the morning hours.

This well mixed lower atmosphere will likely result in limited coverage of the coastal stratus through at least Monday. Moisture within the marine layer will increase by mid-week potentially resulting in higher status coverage in the morning hours despite the continued northerly winds. /RPA /EYS

Aviation
Gusty northerly winds will help keep the terminals in VFR throughout today. Gusts from 25 to 30 kts could be possible along the coast with higher gusts more likely for coastal Del Norte County. For most terminals, winds will calm into this evening allowing the potential for MVFR to IFR ceilings to develop. At CEC, winds are expected to remain elevated making it less likely for cloud cover to develop through this TAF period.

Marine
Northerly gales are expected to persist across the outer waters today, producing hazardous 10-12 foot short period waves across all zones. The highest winds and gusts occurred last night with winds easing a bit today, but still gale force in the outer waters. Significant wave heights to 15 feet at 10-11 seconds are expected in response. Steep and dangerous seas will continue into early next week as gales persist in the outer waters. Current model guidance indicates the strongest winds and wave response shifting to the southern waters by tomorrow before another resurgence of gales early next week. Gales are expected to finally cease by mid next week as the coastal pressure gradient weakens.
