Area Forecast Discussion National Weather Service San Francisco Bay Area 1003 PM PST Wed Dec 11 2019

SYNOPSIS. Lingering light rain continues over the North Bay tonight, after scattered showers passed over the Bay Area earlier this evening. Light rain tapers off Thursday afternoon, but chances for rain returns on Friday and Saturday. Mild temperatures undergo a slow cooling trend toward the weekend. Sunday and Monday morning temperatures will be in the low to mid 40s. By the middle of next week, the forecast shifts back to an unsettled and rainy pattern.

DISCUSSION. as of 08:50 PM PST Wednesday . With consistent moisture from the Pacific continuing to move over the region, a weak short wave that moved over the Bay Area provided enough forcing to bring light to moderate rain to the Bay Area, particularly in the North Bay. Stratus clouds will sit comfortably over the region through the night. The zonal flow will continue tomorrow, so we can't completely rule out the chance of isolated light rain on Thursday. However, better chances are in the early morning due to lingering moisture and then will taper off in the afternoon as a pocket of dry air briefly moves over the region. Temperatures will remain in the 60s and trend cooler into the 50s toward the weekend under cloudy skies.

Regarding Friday into Saturday, we expect rain again for much of the Bay Area. But being only two days out, there is still inconsistency between models on timing. The Euro has it moving in on Friday in the late morning, the NAM has it Friday afternoon, and the GFS has it late on Friday evening. What we do know is that the synoptic guiding pattern bringing subtropical moisture to our region will continue and steady rain through Saturday morning is expected.

Saturday night into Sunday sees the next upper level trough pass over. This will bring in more cold air advection from the northwest allowing low temperatures to drop on Sunday morning. Widespread low- to-mid 40s is forecast with isolated low lying valleys of the North Bay, East Bay and Southern Monterey County is expected to drop into the 30s. Similar chilly temperatures are forecast for Monday morning as well.

In the long range: an upper level ridge builds in the early part of next week helping to drive a slight warm up. As we get closer to the date, models will resolve the magnitude of the brief change in temps. The main story though is what's behind the ridge. Models are beginning to hint at the sign of the next system, that could bring widespread rain for the Bay Area and along the Central Coast for the middle to end of next week.

AVIATION. as of 10:04 PM PST Wednesday . A series of shortwave disturbances will keep abundant low level moisture over the area through Thursday. MVFR cigs will persist with occasional IFR cigs in the valleys and the MRY Bay Area. Occasional light rain and drizzle can be expected mainly from the SFO Bay Area north which is where most of the moisture is. Winds will be light and generally out of the east or southeast.

Vicinity of KSFO . MVFR cigs with bases around 1500-2500 ft. Light southeast winds under 10 kt. Occasional light rain or drizzle.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . Areas of MVFR cigs around the area becoming more widespread after 08Z. Cigs lowering into IFR category at times. Light east to southeasterly winds under 10 kt.

MARINE. as of 09:44 PM PST Wednesday . Light southerly winds will prevail through Thursday before switching to west to northwest. Northwest winds will increase on Saturday as a cool upper trough passes to the north of the area. Large long-period northwest swell will impact the waters Thursday night through Saturday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
