Synopsis for northern california waters - Northerly winds will shift to southerly over the next 24 hours ahead of an approaching front. Moderate to fresh breezes can be expected on Wednesday as the front moves through the waters and also in it's wake. Stronger southerlies are likely late week as a more potent low moves through the region. A long westerly fetch on the south side of this low will build a fresh westerly swell into the waters over the weekend.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 523 AM PDT Tue Mar 19 2024
SYNOPSIS
Unseasonably mild weather continues inland for one more day today, while at or near seasonably coastal temperatures with persistent stratus. Unsettled weather and cooler temperatures return late in the week.
DISCUSSION
Latest GOES-West satellite imagery shows a widespread and deepening marine layer blanketed the coastal waters and extended well inland up the adjacent river valleys. The McKinleyville profiler indicates a marine layer depth up to around 2,000 feet MSL, while 1,500 feet MSL per Bodega Bay profiler. Low clouds will burn off with the daytime heating across the interior, although stratus along the coast are expected to persist with the sea breeze.
Unseasonably mild weather continues inland for one more day today as the high pressure dominates the synoptic pattern over interior Northern California. Interior temperatures are expected to slightly cool across the interior Today. However, highs will be likely to remain above normal.
The ridge aloft begins to weaken and shift eastward during Wednesday, while an upstream shortwave trough approaches the area.
This will bring a cooling trend across the interior, with highs at or near normal. The aforementioned shortwave will swing northeastward toward the Pac NW and Northern California, and bring a slight chance (15-25%) of 0.01" of rain for Del Norte County early Wednesday night. Otherwise, expected a mostly cloudy day across the forecast area. Any lingering light showers are expected to taper off early Thursday morning as a brief shortwave ridge builds in over the region.
Finally, unsettled weather is expected late this week as a cutoff low separates from the jet to our north and approaches the region. An associated frontal boundary, along with a plume of subtropical moisture ingested in the southwesterly flow, will move onshore early Friday morning. This may bring moderate rainfall somewhere along the coast between the Bay Area and OR border, although location will depend on where this plume of moisture makes landfall. A low-level jet in advance of the approaching front will bring warm air advection in from the southwest and aiding in snow levels rise, resultant in stratiform precipitation.
As the low approaches, instability could increase and bring slight chance of thunderstorms near the coast late Friday and Saturday.
While the surface low lift out northward toward Oregon Friday afternoon and evening, becoming in a positive tilted. This will bring a second wave impulse across the area.
In addition, southerly winds are expected to gradually increase early Friday morning and become strong Friday afternoon with the low level jet along the front. Gusts from 25 to 40 mph is expected to develop in response, mainly along the coastal headlands and exposed ridges in Humboldt and Del Norte counties...with locally stronger winds possible in the King Range. NBM probability for wind gust over 45 MPH remain around 20-40% for Friday into Saturday.
The broad upper level trough will moves over the region through the weekend. Snow levels will come down as the upper level trough moves through and brings cold air aloft, generally to around 3,500 to 4,500 feet MSL. Scott Mountain Pass on Hwy 3 will see some snow, up to 3 inches.
VELEZ
AVIATION
Widespread stratus remains in place across the coastal waters early this morning. Some lowering of the ceilings has occurred at the coast with a period of drizzle reported at ACV. But overall ceilings have remained off the surface and visibilities have not reduced much at the terminals. More of an onshore component in the wind fields today will likely result in more persistent stratus at both ACV and CEC today and tonight. VFR will persist for areas inland of the stratus today and again tonight. /RPA
MARINE
Light northerlies will transition to southerlies over the next 24 hours as a front approaches the waters. Moderate to fresh breezes are expected with this first front on Wednesday and following behind the front on Thursday. A more potent area of low pressure will approach the region on Friday bringing small craft southerlies to most of the waters. Winds with turn back to out of the northwest as this area of low pressure moves inland Saturday into Sunday and could also be strong enough winds to meet small craft criteria. In addition to the short period seas building in response to the local winds, a fresh westerly swell will build into the waters over the weekend, potentially peaking near 10 feet late in the weekend, however the magnitude of the swell will greatly depend on the exact track of the low pressure system as it passes through the region. /RPA
