AREA FORECAST DISCUSSION National Weather Service Eureka CA 229 PM PST Sat Mar 6 2021

SYNOPSIS. Light showers will be possible tonight across portions of Del Norte, Humboldt, and Trinity Counties, while frost and freeze conditions occur over Mendocino and Lake Counties. Thereafter, a brief period of dry weather will occur across the region during Sunday. That will be followed by a period of wintry weather Monday through Wednesday.

DISCUSSION. A frontal boundary will weaken as it moves east- southeast across northwest California tonight. An increase in cloud cover accompanied by light showers will occur with the front over portions of Del Norte, Humboldt, and Trinity Counties. Farther south, skies will generally be clear across much of Mendocino and Lake Counties. That will favor stronger radiational cooling supportive of frost and freeze conditions during Sunday morning. Generally dry conditions are expected during Sunday afternoon. That will be followed by increasing cloud cover downstream from a deepening upper trough. The trough will evolve into a large upper low on Monday. In addition, an expansive area of cold midlevel temperatures (-30 to -35 C at 500 mb) will accompany the upper low. As the cold midlevel airmass spreads east, lapse rates will steepen, and buoyancy profiles will become sufficient for isolated thunderstorms in the vicinity of the coast Monday afternoon through Wednesday. Showers and storms may also yield accumulating small hail near sea level.

Otherwise, freezing levels are forecast to fluctuate between 2000 and 3000 feet MSL Monday afternoon through Wednesday morning. The low freezing levels combined with waves of ascent embedded within the upper low will aid in periods of heavy snow showers across the mountains. Travel across mountain roadways and highway passes may be impacted as a result. Showery wintry weather is forecast to clear the region Wednesday night as the upper low moves south toward SRN CA. Post-trough upper ridging will favor dry weather Thursday through Saturday. Thereafter, a return to showery weather may occur by late next weekend.

Garner

AVIATION. Soon after sunrise, the remnant MVFR ceiling gave way to sunshine; however, the abundant surface moisture from overnight rains led to a plethora of cumulus clouds which began drifting north in the light southerly flow. The Spanish Mountain webcam captured this evolution over KUKI when cumulus briefly blossomed with a 1600 ft base before drifting on and lifting. Afternoon westerly breezes pushed some harmless patchy mid level cumulus back over the terminal. VFR conditions will prevail through midnight, when soon after a quick-moving weak front will increase southerly winds and bring periods of MVFR CIGs and VIS with light rain. Conditions should quickly improve tomorrow morning.

MARINE. Light to gentle breezes are persisting over the waters today, positioned in a quiet interlude between weather systems. A northwest swell is fading on track to allow most Small Craft Advisories to expire as the swell is dropping below 10 ft. Advisory level conditions will persist across the northern outer waters as another weak front brings a temporary uptick in southerlies this evening, with gusts 25 to 30 kts. These wind will quickly back off in the early morning hours Sunday; however a larger swell builds in to around 17 ft at 16 seconds by Sunday afternoon. Hoisted Small Craft Advisories for the swell. Intermittent periods of stronger southerlies will persist across the waters through early next week as a series of fronts continues to move through the area.
