Area Forecast Discussion National Weather Service San Francisco Bay Area 356 AM PST Fri Jan 17 2020

SYNOPSIS. Isolated showers will end by around sunrise across the Central Coast. High pressure builds Friday leading to dry and seasonable weather. Quiet weather continues Saturday and Sunday with plenty of sunshine and daytime highs in the 50s. Increasing clouds by Monday leading to a chance of light rain later Monday into Tuesday.

DISCUSSION. as of 2:32 AM PST Friday . Isolated showers continue early this morning, mainly over the ocean and along the Central Coast. For the most part shower activity will end by 12-14z. Will watch and update the forecast by that time should isolated shower chances need to be extended. We are quickly transitioning to weak ridging behind yesterdays cold frontal passage. Look for filtered sunshine today with generally light winds as afternoon highs top out in the mid and upper 50s. After yesterdays active weather it will be a quiet end to the work week with some snow covered hills likely visible this morning.

Will have to be on the lookout for some dense valley fog formation tonight as the boundary layer is moist with inversions building. The flow at the surface may turn light offshore allowing for any Central Valley fog to flow towards the Delta by early Saturday morning. Outside of fog expect sunny and seasonably mild weather for Saturday and Sunday with highs 55-60 and overnight lows 35-45 on average.

Blended/ensemble models bring a chance of rain showers by Monday afternoon while deterministic models remain dry until later Monday night into Tuesday. Official forecasts will show some rain chances Monday afternoon but confidence is low with better chances for some light rain by Tuesday. The pattern is such that any fronts bringing rain early next week would mainly bring light rain with the best chances from the Bay Area northward.

Long range trends remain difficult to pinpoint. A few days ago the pattern was looking drier but latest trends show us returning to the pattern of earlier this month where weak systems skirt Northern California bringing light rain chances. Not seeing any strong storms in the extended but no persistent mid-winter ridge either. The PNA pattern is transitioning from strongly negative (cool and showery) but forecast to oscillate between neutral and slightly negative next week. The MJO is fairly active out in phase 6-7 but currently forecast to fade before making it into phase 8 by the gefs plumes so not expecting that to drive the long range trends. Will take what we can in terms of rainfall through the end of the month and see what February brings.

AVIATION. as of 3:57 AM PST Friday . Scattered showers have decreased and should not impact the terminals this morning. Low level moisture remains with FEW/SCT clouds with bases 2000-5000 ft AGL. Patchy dense fog has developed across the North Bay and will continue through the morning. Low level moisture will persist through the day with stratocu likely becoming a little more widespread under daytime heating. However the TAF sites are expected to remain VFR through the day. Light southeast to east winds are expected through tonight with a brief period of light onshore winds this afternoon. High clouds will increase tonight as a weak system passes to our north.

Vicinity of KSFO . FEW-SCT clouds with bases 3000-5000 ft AGL expected today. VFR anticipated through the day. May see stratocu expand some in coverage this afternoon. Southeast winds around 5 kt this morning through early afternoon becoming variable late this afternoon.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR conditions expected today. FEW/SCT clouds expected with bases 3000-5000 ft AGL through the day. South to southeast winds 10-13 kt at KSNS and 5-10 kt at KMRY this morning.

MARINE. as of 02:50 AM PST Friday . High pressure will build over the area today while a low pressure system spins over the Pacific Northwest offshore waters. This will bring light south winds to the northern waters and light north winds to the southern waters through Saturday. Breezy southeast winds will develop Monday as a frontal system approaches. A moderate northwest swell will arrive late Saturday and Sunday while a larger northwest swell arrives the middle of next week.

MTR WATCHES/WARNINGS/ADVISORIES. Tday. None.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
