AREA FORECAST DISCUSSION National Weather Service Eureka CA 245 PM PST Sat Dec 9 2023

SYNOPSIS
A weak front will bring a chance for rain on Sunday to primarily Humbodlt and Del Norte counties. Dry weather is expected to return Monday and continue through much of the week with just a slight chance for rain Wednesday night.

DISCUSSION
High clouds have been streaming over Northwest California today as a warm front moves into the Pacific Northwest. Moisture will continue to increase over the next several hours with gradually thickening and descending clouds overnight into Sunday from north to south.
Guidance indicates a quick passing cold front will bring moderate to light rain to the northern half of the forecast area on Sunday, possibly spreading a few showers south of Cape Mendocino near the coast Sunday night into Monday morning. Northerly flow will return on Monday bringing an end to any shower activity.

Ridging will build back over the west coast Tuesday into Wednesday allowing temperatures to warm a few degrees across the region. A weakening trough will approach late Wednesday or Thursday bringing another shot of some light rain to northern portions of the area, but quickly rebuilding ridging behind this trough won't allow moisture to spread far inland. Dry conditions will then return for late week with increasing thickness values over the region. /RPA

AVIATION
A high pressure system will continue to affect Northwest California until a weak front approaches from the west. VFR conditions will prevail throughout today and overnight for most of the region as a result. Cloudiness will increase early tomorrow morning as the weak front moves overhead. The cloud deck will approach MVFR conditions at the same time along the coast.

MARINE
Northerlies will continue to turn southerly into this evening, being gentle at most. Mostly calm winds combined with a diminishing northwest swell will contribute to a largely quiet sea state. Southerly winds will briefly increase tomorrow along a weak front, but the strongest gusts will only reach 20 kts at most in the far northern waters. Another westerly swell will build in behind the front. This swell will also be steepest in the northern waters reaching 10 to 12 feet at 13 seconds. This could briefly lead to small craft conditions by early tomorrow morning. Besides a brief period of moderate northerly winds possibly generating short period seas near 5 feet on Monday, an unusually calm sea state is expected for much of next week.
