AREA FORECAST DISCUSSION National Weather Service Eureka CA 342 AM PST Sun Dec 10 2023

SYNOPSIS
A weak front will bring light rain this afternoon and tonight 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. More rain is possible next weekend.

DISCUSSION
A weak frontal boundary will bring some light rain to Humboldt and Del Norte counties. This morning the inland valleys are likely seeing some fog, but confidence is low on this due to high clouds moving overhead and obscuring the low clouds on the night satellite. This front is expected to continue to dissipate as it moves farther south and east. Models continue to slow down the progression of this frontal boundary. Rain is expected to move onshore into Crescent City around midday and then make it to Humboldt Bay by mid to late afternoon. Rainfall amounts look to be between a half inch and an inch in Del Norte county with only a tenth of an inch expected in Eureka and only a trace to a few hundredths by the time it reaches Garberville. In Trinity county the rain is only expected to make it as far east as about Burnt Ranch. By Monday morning only a few showers are expected to linger over Humboldt and Del Norte counties. The inland valleys will likely see fog and low clouds again.

Monday afternoon through Wednesday afternoon high pressure is expected to build over the area bringing dry conditions. Valley fog is likely each night and may linger through midday in some of the more protected valleys. Coverage is still uncertain and may gradually diminish without recent rain. Wednesday night through Thursday morning a weak weather system may bring some light rain to Del Norte and Humboldt counties again. Amounts look very light and there is uncertainty on whether any rain will even make it into California. Thursday night and Friday high pressure is expected to bring dry weather to the area again. The potential for rain increases again through the weekend, however some of the models show a closed low developing off the coast and keep the coast dry through the weekend. MKK

AVIATION
IFR or LIFR condition in low clouds and fog have been occurring over the interior valleys overnight. The fog and low clouds will likely dissipate by late morning. Otherwise, VFR conditions will continue to prevail at forecast terminals today with variable high clouds and some mid cloud decks near the Oregon border over KCEC. A decaying frontal system will move toward coastal areas this afternoon and may produce light rain and MVFR cigs/vsbys for the Del Norte coast. Shallow moist air with the remnants of the front will push onshore late in the day or as late this evening.
MVFR cigs and vsbys in light rain and drizzle are expected for coastal terminals. IFR conditions are also anticipated later in the night for coastal terminals.

MARINE
Steep westerly swell and southerly wind waves will combine to yield seas around 9 to 11 ft in the northern outer waters today. Otherwise, coverage of gusts over 20 kt is well below 50% to warrant an advisory for small craft. Relatively light winds and low seas are forecast for the remainder of the forecast period. Northerly breezes may hit 20 kt in the lee of Cape Mendocino late Monday, but once again coverage of gusts over 20 kt remains below 50% and does not warrant an advisory. After Tue, a light (15kt or less) easterly wind regime will unfold as high pressure moves inland and menders eastward toward 130W. Seas will remain relatively tranquil as well.
