AREA FORECAST DISCUSSION National Weather Service Eureka CA 300 PM PST Tue Mar 2 2021

SYNOPSIS. Dry weather, along with near-normal daytime and cool nighttime temperatures, will occur across northwest California through Wednesday. There is the potential for strong winds late Thursday and early Friday with rain moving in Thursday night and Friday morning. The potential for rain and mountain snow will continue into early next week.

DISCUSSION. An upper low off the S CA coast will gradually fill as it moves ENE. As this feature exits toward the rockies, a broader trough of low pressure will dig S over the E Pacific. Skies across the area have been mostly sunny this afternoon with just some lingering wisps of cirrus rotating around the NE periphery of the S CA upper low. Cold overnight temperatures are expected tonight with frost across portions of the North Coast, Mendocino, and Lake counties. A few of the normally colder locations may reach near or just below freezing again. For now, have just gone with another Frost Advisory for the aforementioned areas.

Dry weather is forecast to persist through mid-week. Thereafter, model guidance shows the cold upper trough over the E Pacific moving eastward across the West Coast Friday and Saturday. A period of moderate to locally heavy frontal rain will be possible Friday afternoon and evening. There are still precip timing and QPF total discrepancies among the long range models. It appears rainfall amounts of between 1 and 2 inches are likely for portions of the North Coast. However, there is the potential for more rainfall, particularly across Del Norte County. Pre-frontal advisory level southerly winds may occur across exposed ridges and coastal areas late Thursday and early Friday. Light mountain snow also appears possible during Saturday as a cold post-frontal mid- level airmass spreads east across the region. Periods of snow may continue across the mountains into early next week, with snow levels occasionally dropping to near 2000 feet. /SEC

AVIATION. At daybreak, most areas were VFR with interval high clouds moving across the Region. Patchy fog developed over a few inland river valleys, and CEC very briefly dipped into IFR due to CIG and HZ obstruction. Minor HZ obstructions expected to continue along the coast through the day. Stratus may develop along the coast this evening although there is room for some uncertainty since no coastal stratus was observed on Visual Satellite by mid- afternoon. Also, none was observed near coastal hills or Eel Delta; model data is showing no significant low level moisture advection/development. VFR and light winds will continue through the TAF period for inland areas. /TA

MARINE. Light northerly winds around 5 to 15 kt continue today, with a local max in the high teens developing off of Cape Mendocino late this afternoon. A mid period NW swell continues to fill in through tonight, when it should peak around 12 ft at 14 seconds, then decay through Wednesday.

A front is expected to approach the coast late this week, bringing a slow moving, wide and robust band of southerly winds starting early Thursday. These winds should efficiently build up short period southerly seas by Thursday night, with heights in the low to mid teens currently forecasted for the outer waters. Meanwhile, another slightly longer period 10 to 12 ft NW swell should arrive on Thursday and last through the weekend, bringing a chance of chaotic combined seas in the high teens to low 20's for Friday. /TDJ&EYS

EKA WATCHES/WARNINGS/ADVISORIES. CA . Frost Advisory from midnight tonight to 9 AM Wednesday for CAZ101-103-109>115.

NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until 6 AM Wednesday for PZZ450-470. Small Craft Advisory from 6 PM this evening to noon Wednesday for PZZ455. Small Craft Advisory until noon Wednesday for PZZ475.
