Area Forecast Discussion National Weather Service San Francisco Bay Area 1021 PM PST Mon Jan 20 2020
SYNOPSIS. Rain chances will increase from north to south late tonight into Tuesday as a weak cold front moves across northern California. Rainfall amounts will be light to locally moderate with no significant impacts expected. Mostly dry and warmer conditions are then expected for the remainder of the week, with rain likely to return next weekend.
DISCUSSION. as of 09:02 PM PST Monday . A low centered well off the coast of Baja California tapped into some subtropical moisture and brought light rainfall mainly south of the Bay Area this afternoon. The precipitation was not resolved well by most of the models and many of our southern locations, especially around Monterey and San Benito Counties, received measurable rainfall. In these areas several hundredths were common with up to 0.12 inches at Pinyon Peak in the Santa Lucia Mountains. Showers have cleared our area and the weather is expected to remain dry overnight ahead of an approaching cold front.
The cold front will move into the North Bay on Tuesday morning gradually shift south through the Bay Area and Central Coast during the afternoon and evening. The front will weaken as it progresses, so heavy rainfall is not expected and rainfall amounts will be highest across the north. Showers will end from north to south, with a chance of showers continuing through Tuesday night across the Central Coast as the front stalls and a weak secondary impulse approaches the coast. Rainfall totals of 0.25"-0.75" will be common across the North Bay, with 0.75"-1.50" over the North Bay coastal mountains. Elsewhere, rainfall amounts will generally be 0.25" or less, except for the Santa Cruz Mountains where up to 0.50"-0.75" will fall. Made some minor adjustments to PoPs tomorrow but otherwise forecast remains on track.
South to southeast winds will be breezy and locally gusty ahead of the front along the coast and hills through the day on Tuesday, but will not be strong enough to warrant advisories. Temperatures behind the front will not change much, with middle to upper 50s common throughout the district. Dry conditions and warmer temperatures are forecast Wednesday through the end of the work week as a ridge of high pressure builds overhead. High temperatures are forecast to warm into the lower to middle 60s Thursday through Saturday, while lows remain mostly in the 40s. The next good chance of rain will return over the weekend, as most of the ECMWF/GFS ensemble members depict wet weather late Saturday into Sunday. This system is likely to bring widespread rain, but unlikely to be strong enough to bring flooding or other significant impacts.
AVIATION. as of 10:21 PM PST Monday . For 06z TAFs it's VFR except local IFR visibilities developing due to fog are possible under a clearing sky; metar observations at Napa and Byron report lowering visibilities in fog/mist. Wet weather with lowering ceilings and visibilities develops Tuesday and Tuesday night as a cold front approaches from the west.
Vicinity of KSFO . VFR borderline MVFR ceilings. VFR forecast for tonight with light rain developing Tuesday then a few lingering showers Tuesday night.
SFO Bridge Approach . Similar to KSFO.
Monterey Bay Terminals . VFR-MVFR. Light SE winds tonight and Tuesday morning. Light rain mid to late Tuesday afternoon and evening.
MARINE. as of 8:10 PM PST Monday . Southerly winds will gradually increase tonight ahead of an approaching cold front that will push through the coastal waters on Tuesday. A longer period northwest swell will also begin to build over the waters tonight before peaking midweek. This will generate hazardous seas conditions for smaller vessels. Another long period northwest swell will then arrive late week.
