Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Northwest winds remain moderate over the northern outermost waters. These locally stronger winds will generate hazardous conditions for small craft vessels. A moderate locally generated northwest swell will prevail through the end of the week. A building southerly swell will move through the waters alongside the chance for rain this coming weekend. Locally gusty winds will accompany these cold front as it sweeps through the waters early Sunday.

Area Forecast Discussion National Weather Service Sacramento CA 255 PM PDT Thu Apr 22 2021

SYNOPSIS. Dry and warm weather through the end of the week. Widespread rain and significant snow return by Sunday into early next week with mountain travel impacts possible.

DISCUSSION. Upper level ridging is building into the region today and that is bringing quiet weather with mostly clear skies. We are continuing to see good flow through the Delta and that is going to continue into the overnight. That is holding temps down some in the Delta and into the Sacramento area this afternoon. Some marine stratus made it into the Valley this morning and currently the Fort Ord profiler has a healthy marine layer of about 3000 feet. Given the deep marine layer, good flow through the Delta and what we saw this morning it seems very reasonable to see some low level clouds in the Delta and Sacramento area tomorrow morning. Any marine clouds that make it into the Valley should clear quick by the mid morning and Delta flow will keep temps cooler once again tomorrow. Also as we head into the afternoon and evening we will see high level clouds build into the region ahead of an approaching short wave trough.

Our weather will be changing as we head into the weekend with more active weather expected. A short wave trough will push over the northern part of the state Friday night into Saturday and will also push a cold front into the region. This will bring light shower chances mainly to the northern mountains. The front will stall out over the region on Saturday and a deeper stronger trough will push it south on Sunday. As this deeper trough approaches NorCal we will see showers increase from north to south Saturday evening into Saturday night and we can expected widespread rain and snow Sunday morning into the afternoon. Activity will become more showers over the Valley during the afternoon Sunday and over the mountains Sunday night. Models are building in some post frontal instability Sunday afternoon mainly form Sacramento north to Redding. With the trough axis approaching NorCal during this time some isolated thunderstorms are possible in this region of CAPE.

Shower activity will continue into Sunday night with the best chances over the mountains as troughing remains in place over the state. The majority of mountain snow accumulation can be expected on Sunday. Snow levels are looking to be between 4500-5500 but will fall to 3500-4500 feet for a time Monday morning. Despite the snow coming during the day on Sunday it will likely come down at a high enough rate for it to accumulate on road surfaces and cause travel impacts. A Winter Storm Watch has been issued for the southern Cascade and northern Sierra for Saturday night into Monday morning. Snow totals are looking to be 8-16" with locally higher amounts above 7000 feet. Rain totals in the Valley are looking to be between 0.15-1.15" and Foothill totals 0.75-2.15".

Breezy onshore winds are also expected on Saturday and Sunday. Valley gusts to 30 mph will be possible and we could see mountain ridge gusts up to 50 mph. This trough will also bring in much cooler air and we will see daytime highs as much as 25 degrees cooler Sunday compared to Friday and 15-25 degrees below average. These highs look to remain warm enough to not set any new cold highs for that day but we will likely be within a few degrees of these records.

-CJM

EXTENDED DISCUSSION (Monday THROUGH Thursday). While the bulk of this weekend's system will have wrapped up, some lingering rain and snow showers are expected into Monday afternoon. Best chance will be in the foothills and mountains where the National Blend of Models paints a 25 to 40 percent chance from Shasta County south to Yosemite National Park. Longwave trough axis will push inland on Tuesday as an upper level ridge starts to rebuild over the Pacific Northwest and far northern California. Ensembles generally favor ridging through the end of the next week with day-to-day warming. 80s will become more common in the Sacramento and northern San Joaquin Valley around Thursday. // Rowe

AVIATION. VFR conditions are generally forecast to prevail across northern interior California over the next 24 hours. The exception to this is around the Delta and the Sacramento area terminals where marine stratus may bring brief periods of MVFR/IFR-level ceilings around sunrise Friday. Locally breezy westerly winds with gusts up to around 25 kt will impact the Delta region; elsewhere, winds will generally remain at/below 15 kt through the TAF period.

STO WATCHES/WARNINGS/ADVISORIES. Winter Storm Watch from Saturday evening through Monday morning for West Slope Northern Sierra Nevada-Western Plumas County/Lassen Park.
