Area Forecast Discussion National Weather Service San Francisco Bay Area 1031 AM PDT Sat Mar 28 2020

SYNOPSIS. Light rain showers on and off today for the Bay Area under cloudy skies. There may be a brief lull in showers tonight before the cold front arrives with another round of organized, mainly light rainfall Sunday morning into Sunday afternoon. Skies turn partly cloudy and showers end by Sunday evening. High pressure builds next week with a warming and drying trend.

DISCUSSION. as of 8:54 AM PDT Saturday . Radar continues to show widespread light rain across the region with most Bay Area locations reporting some light rain so far this morning. The system is weak and disorganized and we are currently in the warm advection region which is driving ascent and leading to the precip. There may be a brief lull in precip later this afternoon and evening but still need to hold onto light rain chances through tonight. Sunday morning the surface cold front and trough of cold air aloft will pass through the region. This will lead to a more organized period of rainfall for Sunday morning into early Sunday afternoon as the front moves through. Rain totals 0.25-0.50 on average with 0.10-0.25 for the interior valleys by Sunday evening.

The front is out of the region with dry conditions Sunday night. One fly in the ointment we'll have to monitor is the last few model runs of the NAM bring another shot of light rain to the North Bay on Monday. Will fine tune forecast on those details for this afternoon but high confidence for dry weather south of the Golden Gate on Monday with any North Bay rain on Monday being very light.

Increasing confidence that a prolong period of dry weather returns for the first week of April though longer range trends suggest more precip is possible beyond day 10.

AVIATION. as of 10:31 AM PDT Saturday . For 18z tafs. Radar is still picking up scattered showers across the region. Expect periods of showers to continue on and off throughout the day before another round of more steady precipitation arrives with a secondary boundary tomorrow morning. Borderline MVFR/VFR cigs expected today with current observations showing layers of SCT to BKN cigs between 2,000 and 7,000 ft AGL. S/SE winds expected this morning to remain generally under 10 kt, through short durations at or just above 10 kt will be possible. Latest guidance this morning has backed off on winds shifting to the SW/W this afternoon for some sites. S/SE winds may persist through tomorrow morning for those locations.

Vicinity of KSFO . Light scattered showers on and off throughout the day with borderline MVFR/VFR cigs. Current obs show BKN cigs between 3,500 and 5,000 ft. Periods of MVFR cigs will be possible today, though confidence is low on exact timing and duration. S/SE winds to persist today with winds now expected to increase to 10 kt this afternoon. Latest guidance has backed off on a transition to SW/W winds later today, but should conditions change the taf will be amended. Additional round of more steady showers expected tomorrow morning as a secondary boundary moves through.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR with periods of MVFR conditions and showers this afternoon. MVFR conditions expected this evening and overnight. Additional round of steady showers tomorrow morning. S/SE winds 5-10 kt this morning becoming W/SW in the afternoon. SE winds to return this evening and become locally breezy down the Salinas Valley in the morning.

MARINE. as of 08:20 AM PDT Saturday . High pressure will shift into the southern California waters as a low pressure system moves into waters off the coast of the Pacific Northwest. This will keep winds generally light through the weekend and into early next week. Mixed swell will persist with a moderate northwest swell and a light southwesterly swell.

MTR WATCHES/WARNINGS/ADVISORIES. Tday. None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
