Marine Weather and Tide Forecast for Fields Landing, CA

DISCUSSION
An upper level trough remains offshore the Pacific Northwest early this morning, keeping a weak high pressure in place.
High temperatures are forecast to trend upward, with most interior valleys seeing mid to upper 80's by Sunday. Breezy afternoon winds are likely along the coastal areas again, with high NBM probabilities for over 20-25 mph peak gusts. The highest gusts remain on ridges and coastal headlands, where gusts above 30 mph are possible. The trough to our northwest will slowly move toward our area, with occasional shortwaves bringing a few high clouds and keeping interior temperatures moderated. The trough moves through Monday, but this continues to look dry. Thunder potential in the interior also is unlikely as instability looks meager.

High pressure builds back in Monday, returning the warming trend to the interior. NBM is showing over 50% probabilities for 90's in the warmest interior valleys (eastern Trinity, eastern Mendocino, and southern Lake) by Wednesday. Western Mendocino, including Ukiah, have lower probabilities (~20%) as marine air has a better chance of moderating temperatures. Clusters are starting to coalesce around a trough digging into our area by Friday. Precipitation chances remain low as NBM probabilities for measurable precipitation is around 25% over Del Norte for Friday and Saturday. The main impacts are likely to be temperatures trending downward late week into next weekend and perhaps increased winds. A few ensemble members do have this progressing as an inside slider type of system, moving to our north and east, which are usually indicative of offshore flow and perhaps gusty winds. This could be a fire weather threat and needs to be watched. JB



AVIATION
14/06Z TAFs...VFR conditions prevail across the TAFs aerodrome terminals. Stratus will continue to developed in the vicinity of Humboldt Bay and Eel River valley overnight, while increasing high level clouds from west-southwest stream across Northwest California. Low clouds are possible to bring high end IFR to MVFR ceiling to ACV early Saturday morning. There is a 35% chance for ceilings at or below FL010 at ACV. Otherwise, any low clouds are forecast to lift and mix out with the diurnal heating allowing VFR conditions across Northwest California. Gusty NW winds will redevelop again Saturday afternoon, especially at CEC where gusts up to around 27 mph is likely. Weaker occasional gusts between 15-20 mph for ACV and UKI.

Strong to near gale force gusts are forecast to continue through the weekend, with the strongest winds across the outer waters and southern inner waters. Locally gale force gusts downwind of Cape Mendocino and Point Saint George. The sea state will be largely dominated by steep short period wind waves. A small southerly long period swell around 2-3 feet at 19 to 20 seconds will arrive late Saturday night. Winds are forecast to gradually decrease and retreat to the southern waters early next week.
