AREA FORECAST DISCUSSION National Weather Service Eureka CA 559 AM PST Tue Nov 28 2023

SYNOPSIS
Dry conditions today will be followed by light to moderate rain tonight into Wednesday, mostly south of Cape Mendocino. An active period in the latter half of the week will bring more chances for precipitation in northern zones with some interior mountain snow.
Potential for more impactful rainfall is possible next week.



DISCUSSION
Cold temperatures remain prevalent in the inland valleys with some locations already seeing lows in the 20's early this morning. Coastal zones are not expected to dip below freezing as light easterlies promote relative downslope warming. High cirrus are beginning to stream onshore ahead of a weakening upper low that has slowly been approaching the region. Cloud cover will rapidly fill in this evening as the low pushes onshore, bringing the likelihood for beneficial rain showers to the southern zones of the CWA, mainly south of Cape Mendocino, through Wednesday morning.
Limited clearing will occur in its wake as we enter an active period dominated by a series of upper level shortwaves. More precipitation is expected Thursday and Friday in quick succession with most of the moisture concentrated in regions of Del Norte, Trinity and Humboldt counties, with interior mountain snow likely at around 4,000 ft.
Snow levels will continue dipping into the 2,000 to 3,000 ft Friday as a colder airmass remains consistent over the PNW.

This active period will drive additional waves of precipitation through the weekend and into early next week. The impacts of more significant rainfall are still being determined as the location of an offshore ridge remains uncertain across model guidance. The positioning of this high pressure will steer subtropical moisture into the PNW, but could remain concentrated north of California.

AVIATION
Scattered high clouds stream over NWRN CA this morning, and VFR is expected to continue through the day today. A closed upper low slowly approaches the coast this afternoon, slowly bringing more high cloud through the day. This low is expected to bring light rain showers to primarily Mendocino, Lake, and southern Humboldt counties late this evening through early Wednesday, although a few showers may stray north of Cape Mendocino. Impacts to aviation from this system are expected to be minimal, with possibly broken MVFR ceilings developing late tonight for areas south of Cape Mendo. Otherwise VFR is expected to persist for areas to the north.

MARINE
A closed upper low approaches the west coast today, bringing southeasterly winds in the mid 20 kts range in the outer waters this afternoon and tonight, primarily in the southern outers.
Winds weaken and turn northerly as this system moves onshore Wednesday morning, then northerlies strengthen further late Thursday behind another weak frontal passage. Short period SE seas briefly build tonight in the outers then weaken with the winds early Wednesday. Otherwise, a series of small W swells trickle in over the next couple of days, with relatively benign seas expected until the northerlies strengthen late Thursday. The first in a series of larger, fresh NW swells is then expected to fill in Friday and be continually reinforced through the weekend...with seas possibly remaining at or above 10 ft into early next week.

Tides/Coastal Flooding...The current full moon phase is bringing higher than usual tidal swings, while local southerly winds are contributing to a slowly increasing tidal anomaly. The North Spit tide gauge is currently running around a 0.9 ft tidal anomaly, and the forecasted high early this afternoon is 7.98 ft. If the tidal anomaly persists, tides should be just barely over the 8.8 ft or greater tidal level required for a Coastal Flood Advisory. Very minor coastal flooding is possible around the usual spots around Humboldt Bay around noon, particularly in King Salmon and Jackson Ranch Rd in the Arcata Bottoms.
