Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... A large storm classified as an atmospheric river will move across the region late today through the coming days. Strengthening southerly winds will rapidly strengthen to gale to storm force as the front approaches and passes over the waters, with peak gusts in excess of 55kt across the waters. These winds will generate extremely steep fresh southerly seas at a periodicity of 7 to 9 seconds through tonight and will mix with a moderate northwest swell.

Area Forecast Discussion National Weather Service Sacramento CA 357 PM PST Tue Jan 26 2021

SYNOPSIS. A long duration, high impact winter storm this evening into Friday bringing periods of gusty winds and moderate to heavy rain and mountain snow, and blizzard conditions over the Northern Sierra. Potential for significant low elevation snow and damaging winds tonight and Wednesday as well as burn scar impacts to the LNU Complex and SCU Complex burn scars.

DISCUSSION. The highly advertised strong winter storm is beginning to move into Northern California this afternoon as the upper level trough begins to move onshore. Current radar imagery shows showers moving into the forecast area along the western edge, and they are expected to expand to the east through the afternoon. Precipitation will quickly become heavy tonight. NAM 3k and HRRR are both indicating the formation of a NCFR (narrow cold frontal band) along the cold front as it moves through the area, generally after 8pm tonight through 8am tomorrow. This is expected to produce very heavy precipitation with high rain and snow rates. HREF suggests hourly snow rates with this band of 2 to 6 inches in the Sierra, including over Interstate 80 and Highway 50. Winds will also become extremely strong as the cold front passes through with damaging gusts up to 50 to 60 mph expected in the Valley up through the mountains, locally up to 70+ mph winds over higher mountain peaks. These extreme snowfall rates plus strong winds will produce extreme weather conditions and near zero to zero visibility over the Northern Sierra. Therefore, a Blizzard Warning has been issued for the Northern Sierra for elevations above 3000 feet. The Winter Storm Warning remains in effect for the remainder of the mountains, foothills, and Northern Sacramento Valley. Winds these strong plus heavy mountain snow are also likely to cause downed trees or tree branches and powerlines. Widespread power outages are possible tonight through tomorrow morning.

In the Valley, rain rates around 1 to 2 inches per hour are possible overnight tonight. HREF is suggesting the best chances for the rain rain rates greater than 0.50 to 1 inch per hour will be over western Yolo County into Solano County and south into western San Joaquin and Stanislaus County, including the LNU Complex and SCU Complex burn scars. Impacts such as debris flows are definitely a concern overnight with this pattern. A Flash Flood Watch remains in effect for both of those burn scars.

This will be a cold storm to begin with as the trough is dropping down from the Gulf of Alaska. Snow levels will begin very low this evening through tomorrow morning, generally 500 to 2000 feet, dropping to the valley floor in the northern Sacramento Valley. Several inches of snow is forecast to the valley floor in Shasta County and Tehama County. This snow at these low levels could cause major travel delays as well as downed tree branches and localized power outages. Snow levels will rise to around 3000 feet by tomorrow afternoon, remaining locally down to 2000 feet in Shasta county.

The trough axis will continue to deepen just off the California coast tomorrow, stalling the cold front over the area. Precipitation will continue through the day, though it will be lighter than overnight. Then precipitation is expected to pick up again overnight Wednesday into Thursday, heaviest along and south of Interstate 80. This could bring renewed concerns for the LNU Complex and SCU Complex burn scars, which is why the Flash Flood Watch is through 4pm Thursday. Snow levels will generally be between 3000 to 4000 feet, rising above 4000 feet during the day Thursday. Showers will continue overnight Thursday and lighter through the day on Friday, mainly over the higher elevations. -HEC

EXTENDED DISCUSSION (Saturday THROUGH Tuesday). Cluster analysis is in good agreement troughing off the Pacific Northwest Coast will continue into next week. This unsettled synoptic pattern is typical for this time of year and will bring beneficial moisture to the area. Another more impactful winter storm could reach Northern California by early next week. Preliminarily, we could see over an inch of rain for valley locations as well as several feet of snow for higher elevations. The euro ensemble is indicating a 100% chance of snow exceeding 3 feet for a large region over the higher elevations of the Sierra including mountain passes. Anomaly tables are also hinting at the possibility for some gusty winds with this system as well. There is still uncertainty in the forecast so check back for updates.

AVIATION. Widespread MVFR/IFR conditions develop across the Central Valley between after 00Z Wednesday with IFR/LIFR developing over the mountains associated with heavy rain and snow moves into the area. Low snow levels with accumulating snow likely at KRDD and KRBL beginning this evening. Increasing southerly surface wind gusts 35-50 kts, locally higher, after 03Z Wednesday.

STO WATCHES/WARNINGS/ADVISORIES. Winter Storm Warning until 2 AM PST Friday for Burney Basin / Eastern Shasta County-Central Sacramento Valley-Motherlode- Mountains Southwestern Shasta County to Western Colusa County- Northeast Foothills/Sacramento Valley-Northern Sacramento Valley- Shasta Lake Area / Northern Shasta County-Western Plumas County/Lassen Park.

Blizzard Warning until 2 AM PST Friday for West Slope Northern Sierra Nevada.

High Wind Warning from 8 PM this evening to noon PST Wednesday for Carquinez Strait and Delta-Central Sacramento Valley- Motherlode-Mountains Southwestern Shasta County to Western Colusa County-Northeast Foothills/Sacramento Valley-Northern Sacramento Valley-Northern San Joaquin Valley-Southern Sacramento Valley.

Flash Flood Watch through Thursday afternoon for Northern San Joaquin Valley-Southern Sacramento Valley.
