Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Light split flow winds through the early afternoon, with increasing southerly winds in the northern waters and weakening northerly winds in the southern waters. Winds shift to become south to southwest across the waters by this evening ahead of a surface frontal boundary before shifting to become northerly by Sunday morning. A long period west to northwest swell will continue to impact the waters through Saturday. This will create conditions hazardous to small crafts. Additional long period northwest swells will arrive this weekend and early next week.

Area Forecast Discussion National Weather Service Sacramento CA 257 AM PST Sat Jan 25 2020

Synopsis. Patchy valley fog possible this morning. Light showers possible Saturday, with a wetter Pacific storm tonight through Sunday. Unsettled weather continues early next week.

Discussion. Brief upper level ridging has built over NorCal overnight. Radar has shown light warm air advection precipitation in Shasta County throughout the night. Showers are expected to linger through the morning for Shasta County and the northern mountains. Areas of Valley fog, locally dense, are possible through mid morning. Visibilities are beginning to lower in the northern San Joaquin Valley early this morning and are expected to continue lowering this morning.

A Pacific frontal system approaches NorCal today bringing more widespread precipitation tonight through tomorrow. The heaviest precipitation will be overnight tonight through early Sunday morning, with showers lingering mainly over the mountains and northern Sacramento Valley throughout Sunday afternoon. Liquid precipitation amounts look similar to previous forecast and will range from 0.2 to 1 inch in the Valley to 0.5 to 2 inches in the foothills and mountains. There is a chance of one or two weak post- frontal thunderstorms in the foothills Sunday morning through mid afternoon, though CAPE looks fairly weak even for CA standards. Heavy rain and accumulating small hail would be the main threat with heavier cells.

In terms of precipitation type, this begins as a warm storm with snow levels above 8,000 feet Saturday evening when the storm moves in. Snow levels will slowly fall overnight to around 6,000 to 6,500 feet by early Sunday, then they will fall slightly more Sunday morning to 5,500 to 6,000 feet after the front moves through. Because of the higher snow levels during the time of heaviest precipitation, snow amounts are not likely to be very high and snow accumulation is not expected until late Saturday night/early Sunday morning. General forecast remains around 1 to 4 inches over the major Sierra passes (I-80 and Highway 50) with around 6 to 8 inches for elevations above 7,000 feet south of Highway 50. Therefore, significant mountain travel impacts are not expected with this system.

Precipitation from this system is expected to move out of the area by Sunday night and the upper trough moves east into the Great Basin region. Upper level ridging builds once again for Monday with the potential for warm air advection bringing light showers to Shasta County. Areas of dense fog are also likely to form in the Valley Monday morning.

Ensembles continue to show an upper trough moving through the PacNW late Monday into Tuesday. This will likely just clip NorCal with the main impacts remaining well north of the forecast area. Precipitation chances remain mainly limited to the mountains and northern Sacramento Valley with a few stray showers possible in the rest of the Valley. Precipitation accumulation is forecast to be fairly minimal at this time. HEC

EXTENDED DISCUSSION (Wednesday THROUGH Saturday). Ensemble means and latest ops runs indicate strong ridging along the West Coast during the second half of next week resulting in dry weather with above average temperatures across the region. Weak systems moving over the ridge will bring occasional cloudiness along with a slight chance of showers at times across the far northern portion of the forecast area.

AVIATION. MVFR conditions predominate with a few showers thru about 18Z- 20Z, then mainly VFR over the Central Valley with MVFR/local IFR over the mountains. Widespread MVFR with local IFR after 00Z Sunday as Pacific frontal system moves inland across NorCal. Areas southerly wind gusts 15-25 kts develop after 08Z Sunday.

STO WATCHES/WARNINGS/ADVISORIES. None.
