Synopsis for the Central California Coast and Bays Including the Monterey Bay, Greater Farallones and Cordell Bank National Marine Sanctuaries - PZZ500
Breezy and gusty northwest winds to last through early work week. These winds will generate steep hazardous wind waves which can be hazardous to smaller vessels. A low pressure system will move southward across the offshore waters bringing a chance of rain to our coastal waters Monday night and Tuesday morning. A weakening northwest swell will likely be dominated by wind generated waves through the coming days. These wind waves will eventually build to periods of 8 to 10 seconds through the work week.

Synopsis
Breezy in the hills tonight into Monday. Light rain showers Monday night into Tuesday with light accumulations at best. Quiet through mid week with rain chances returning by Thursday. Cooler temperatures for late week into the weekend.

As of 2:35pm PST Sunday... Today through Wednesday:

High pressure at the surface and aloft will center west of the area today promoting drier north to northeast winds. After a cloudy and foggy start expect continued erosion/thinning of cloud cover through the afternoon. Temperatures should rebound nicely in the interior valleys with highs in the mid to upper 60s. However given slower clearing expect cooler temperatures for the coast and bays, with readings in the upper 50s and lower 60s.

For tonight into Monday high pressure should shift away to our southwest as a shortwave trough drops southeast across the eastern Pacific and CA. Of the 05.12z deterministic guidance the ECMWF (European Centre for Medium-Range Weather Forecasts) is a bit more supportive of light precipitation by Monday evening with the upper wave/vort max tracking a bit closer to the Central Coast. In contrast, the GFS is more offshore with the upper feature and corresponding large-scale forcing for ascent. Regardless of track, ensembles suggest only light rain accumulations generally on the order of .15" or less (ECWMF) to a few hundredths (GFS), so this won't be a washout by any stretch of the imagination.

Winds should increase tonight into Monday in the hills as northerly 925 mb magnitudes peak around 30-40 kt. Gusty conditions are likely around and above 2500 ft. Some of the high resolution guidance members suggest limited downward momentum transfer into the surface layer and resultant fog development late tonight into Monday. Others suggest more of a BR/stratus mix. Given expected winds/mixing am more supportive of the stratus scenario, but couldn't rule out some fog here or there.

Temperatures should be pretty close to seasonal averages with highs generally in the 50s to lower/mid 60s (warmer in the southern valleys) and lows mostly in the 40s.

Transient high pressure will bring quiet conditions and seasonally warm temperatures for Tuesday followed by cooling by mid week.

Wednesday Night through Sunday:

A more progressive pattern should take shape as upper troughing sharpens along the west coast on Wednesday into Thursday. Rain chances should accompany this system Wednesday night into Thursday. In general it appears that this system should remain progressive with light rain amounts, but there's time to fine tune this going forward. With thicknesses and snow levels dropping it's possible that precipitation may end as light snow for peaks above 3000 ft. That said, the latest model trend delays the cooling just enough that precipitation may be over before the coldest air arrives.
