AREA FORECAST DISCUSSION National Weather Service Eureka CA 459 AM PST Sun Dec 8 2019

SYNOPSIS. Clouds and a few showers will linger across northwest California this morning in the wake of a departing storm system. High pressure will bring dry weather for Monday with gradually clearing skies after some valley fog. A weak front will then bring light rain in on Tuesday, with mild but showery weather continuing through much of the remainder of the week.

DISCUSSION. A weakening upper-level trough and associated surface low pressure has pushed inland and will track off to our southeast today, resulting in an end to our wet and windy weather. A few spotty showers will linger this morning, especially across the inland mountainous terrain, but additional rainfall amounts will be on the light side; mainly a tenth of an inch or less. Overcast skies cover most of northwest California this morning, and as winds have calmed down during the overnight hours, some patchy fog has developed. A highly amplified high pressure ridge and weak surface high will build into the West Coast later today and tonight. With that, drier air will filter in with subsidence, but lingering low level moisture will be capped under a strengthening inversion. Still think the low clouds will thin and scatter for many areas by the end of the day today, especially along the coast, but am not fully confident in too much sun this afternoon. Otherwise, expect a seasonably mild day with much lighter winds than the last couple of days.

By tonight while we should see clearing skies, low clouds and fog will likely be rather quick to redevelop in the valley areas and possibly along portions of the coastal plain as well. Expect a cooler night than the last few, with low 40s along the coast and 30s inland by Monday morning. Fog may be rather persistent across the inland valleys with plenty of low-level moisture trapped under a strong inversion. Otherwise, Monday may end up being one of the nicest days of the upcoming week, with a fair amount of sun and light winds, and no precipitation.

By Tuesday, the next front will be headed our way. This wave will be working through the broad ridge along the West Coast, and will thus lack much upper-level support or moisture . so only light rainfall is expected. A much stronger upper trough will then drop into the Gulf of Alaska, sending a series of shortwaves toward the Pacific Northwest through the end of the week. None of these waves look particularly strong, but rainfall may add up to some substantial amounts during the Wednesday night through Saturday time period, especially near the Oregon border. Rainfall will be lighter and more intermittent farther south into Mendocino county. Expect all of this rainfall to be beneficial, and do not see any periods of strong winds at this point, so impacts with this period of unsettled weather will be minimal. National Blend Model guidance has been consistent in cooler air eventually settling in next weekend with lowering snow levels; otherwise expect just rain at all our highway passes this week. /AAD

AVIATION. Low ceilings have formed overnight along the North Coast in the wake of a cold front. These should lift a hair by mid- morning for mostly MVFR ceilings through much of today. Stratus is building farther offshore as well, and when combined with the light northerly winds expected today, should continue to reinforce the low clouds. There is a chance that these may scatter out this afternoon, but confidence is currently low as to whether this will occur or not. Regardless, low clouds should return to the coast tonight for another round of impacted ceilings. For inland areas, scattered showers may continue to impact flying conditions through mid- morning, however widespread clearing is expected this afternoon as the front exits to the east and daytime heating mixes out residual low clouds. /TDJ

MARINE. Light northerlies have developed overnight and are expected to continue through tonight across all waters. Winds then go light and variable through Monday before accelerating from the south on Tuesday as another front approaches the coast, possibly reaching SCY levels in the outer waters. Seas will continue to decay today and tomorrow before slightly building again Tuesday in response to the southerlies and a new NW swell filling in.

Additionally, a significant NW swell is expected late in the week in response to a nearly basin- wide cyclone developing and tracking eastward across the Northern Pacific mid- week. Current guidance is showing this swell filling in Thursday and peaking around Friday morning somewhere in the region of 16 ft at 18 seconds, with a few pulses continually reinforcing each other through next weekend. However precise timing of these pulses will likely change as the system develops across the NWPAC. /TDJ
