Area Forecast Discussion National Weather Service San Francisco Bay Area 411 PM PST Fri Jan 24 2020

SYNOPSIS. Another weak front will pass over the region tonight with some sprinkles possible for the North Bay but mainly dry conditions are expected overall. A warm front will bring some light rain chances to the North Bay late Saturday, spreading south across the rest of the Bay Area Saturday night into early Sunday. Rain amounts will be light overall with a drying trend Sunday afternoon through early next week as temperatures trend to above normal.

DISCUSSION. as of 1:42 PM PST Friday . Fog finally cleared but it was stubborn in a few locations, not clearing until late morning. Satellite imagery shows mostly clear skies from about the San Francisco Bays southward, with increasing clouds across the North Bay. Current temperature trends are similar to or slightly warmer than those from yesterday at this time with upper 50s to mid 60s across the area. A weak impulse is progged to bring rain chances to mainly the North Bay tonight, otherwise areas of valley fog are expected to form again tonight. Overnight lows will be mild, with mid 40s to lower 50s expected.

High pressure will briefly rebuild over the area allowing for another round of night/morning fog followed by mild afternoon temperatures on Saturday with highs in the 60s. The ridge will weaken later in the day as a weak front approaches. Light rain chances will return to the North Bay late in the day Saturday. Rain chances increase and eventually spread southward Saturday night through Sunday. Rainfall amounts over the weekend will generally be a few hundredths to a tenth or two. Highest rainfall amounts will be over the North Bay and up to nearly three quarters of an inch there at most.

Another very weak impulse will bring another chance for light rain to the North Bay late Monday into Tuesday. Dry weather is then expected for the rest of the week and possibly beyond as a blocking ridge pattern sets up over the west. The latest 8-14 day climate outlooks from the Climate Prediction Center indicate moderate-to-high probabilities of above normal temperatures and below normal precip for the period of January 31 through February 6th.

AVIATION. as of 4:10 PM PST Friday . For 00Z TAFs. VFR conditions are anticipated across most of the area this evening. Mid to high clouds are increasing ahead of another weak boundary moving into the Bay Area tonight. Clouds will lower overnight, becoming MVFR. IFR cigs are anticipated across much of the area early Saturday morning as low level moisture increases. Fog is also possible as models indicate the near surface conditions will be nearly saturated. Locally dense fog is possible across the North and East Bay as well as around Monterey Bay. Lower confidence on dense fog potential around the Bay Area terminals. Scattered showers are likely this evening across the North Bay and a few isolated showers may make it south into the Bay Area. VFR conditions are generally expected Saturday afternoon, with SCT to BKN clouds between 3,000 and 5,000 ft AGL. Winds should remain generally light with typical terrain and diurnal patterns through Saturday afternoon.

Vicinity of KSFO . Onshore winds will continue through the evening and gradually decrease. An isolated shower is possible this evening. MVFR cigs returning around 07z to 08z lowering to IFR around 12z. Potential is there for fog Saturday morning and dense fog cannot be ruled out. Periods of LIFR cigs are also possible. Conditions will improve Saturday afternoon, but SCT to BKN clouds 2,000-4,000 ft AGL will persist. Light northeast winds Saturday morning becoming onshore in the afternoon.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR will continue through the early evening. Low clouds will increase later this evening and overnight with mainly MVFR cigs prevailing, however periods of IFR are also possible. Patchy fog will redevelop Saturday morning and may impact the terminals. VFR conditions expected Saturday afternoon. Generally light winds through the period with offshore winds tonight and onshore Saturday afternoon.

MARINE. as of 8:48 AM PST Friday . Generally light winds today with southerly winds over the northern waters and north to northwest winds over the southern waters. Locally breezy winds are expected along the Big Sur Coast today south of Point Sur. Winds will then become west to southwest late Saturday and into Sunday as the next system approaches. A long period west to northwest swell will move through the waters peaking today and tomorrow. This will create conditions hazardous to small crafts. Additional long period northwest swells will arrive this weekend and early next week.

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.
