Synopsis for northern california waters - Winds and seas will continue to diminish from south to north through late this afternoon and evening. Wave heights are expected to fall to 5-6 feet by Friday beneath light northerlies. Northerly winds will then rapidly increase Saturday behind a front. These winds will further increase on Sunday when gale conditions will be likely in portions of the waters.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 210 PM PDT Thu Apr 18 2024
SYNOPSIS
Dry weather and mild temperatures are expected to continue through Friday. A weak cold front will bring a slight chance of light rain and drizzle to the North Coast on Saturday followed by breezy northerly winds on Sunday.
DISCUSSION
It was another pleasant day across NW California today with above normal high temperatures (mid 70s to mid 80s) for the interior valleys after another chilly start (low temps in the mid 30s to mid 40s). Coastal areas were near normal; a couple degrees either side of 60F. Upper ridge offshore extending northward into western British Columbia will slowly shift eastward Friday through Saturday. Large scale sinking associated with the upper ridge coupled with light offshore wind flow will result in another stellar day with pleasant interior high temps on Friday.
The one downside is the potential for stratus and fog along the Mendocino coast on Friday. Signature for a southerly wind reversal and stratus north of Cape Mendocino in not as pronounced. Low stratus clouds will probably form offshore over the waters and spread onto the North Coast Friday night in advance of a weak front.
A weak front associated with a transient shortwave trough will bring a push low level moisture and perhaps some light rain and drizzle to Del Norte and northern Humboldt counties, primarily during the afternoon on Saturday. Otherwise, dry weather and some cooling of interior high temps are expected in response to breezy west-northwest winds and greater cloud cover across the interior.
Surface high pressure will build in quickly over the Pacific Northwest Saturday night and Sunday in the wake of the front.
Breezy northerly winds are forecast to redeveloped over mostly coastal areas as surface pressure gradients tighten on Sunday.
NBM probabilities indicates a 60-80% chance for wind gusts from 30-40 MPH along the exposed ridges and coastal headlands of Del Norte/Humboldt Counties on Sunday. Also, gusty west-northwest winds will most likely develop through channeled terrain in the interior behind the front Saturday evening.
After a brief period of interior warming and upper ridging, interior temperatures are forecast to trend down mid to late next week as another upper-trough-complex impacts the west coast. The magnitude and rate of cooling remains highly uncertain at this point with 25-75th spreads on the order 10F for high temps and 5F for low temps. Current forecast is for near normal temperatures; highs in the 60s and lows mostly in the 40s. There are subtle indications for convection across mainly Trinity County on Tuesday as an upper trough with limited moisture generates instability.
Potential for precip (showers) will also increase mid to late next week, though amounts will most likely wont be very much with RAW ensemble probabilities of 20% to 30% for > 1 inch of rain in 24-hours for the western slopes of Del Norte and northern Humboldt. Stay tuned. DB
AVIATION
VFR conditions prevail this afternoon at all terminals. Mid to high level clouds will increase from the west throughout the day. Though the northerly winds have relaxed today, a dry, well-mixed boundary layer continues to thwart stratus formation through this TAF period. Further easing of the northerly winds, along with developing coastal return flow eddies, will begin to increase stratus chances starting later Friday. /JJW
MARINE
Northerly winds will continue to trend lower today. Steep seas are also on the way down, and will drop below 7 feet in all zones into early Friday morning. Winds will become light and variable in the nearshore inner zones tonight, with periods of southerly return flow. The northerlies will sharply increase Saturday afternoon behind a passing front. The northerly winds will further increase Sunday into Monday when Gale conditions now seem probable. There is currently 85 to 95% for gusts over 34 kt over the southern outer waters, and 65 to 75% for the northern outer zone Sunday afternoon. Other than small 2-3 foot long-period southerly swells, and a small, mid-period swell over the weekend, the sea state will be dominated locally generated short-period seas. /JJW
