Area Forecast Discussion National Weather Service San Francisco Bay Area 1013 PM PST Tue Jan 21 2020

SYNOPSIS. Mostly dry and warmer conditions will return mid week with rain likely to return over the upcoming weekend.

DISCUSSION. as of 9:23 PM PST Tuesday . The cold front has generated mainly light rain and drizzle and continues to fizzle out as it moves southeast this evening. However, over the North Bay localized amounts of over 1 inch have been measured, for example Mt Veeder with 1.30 inches, 1.28 inches in Angwin, 1.49 inches Mill Valley/Mt Tam (locally higher amounts nearby) and 1.70 inches in Kentfield. To the south amounts dropped off fairly quickly with a few hundredths to locally a couple tenths of an inch to isolated amounts near one third to seven tenths of an inch over the East Bay to the Santa Cruz Mountains. Only a few hundredths of an inch have been measured on the North Central Coast.

Drier weather returns Wednesday and Thursday with warmer temperatures as an upper level ridge builds in from the west, patchy valley fog is likely at night and early morning hours. For additional information please see previous discussion.

PREV DISCUSSION. as of 2:33 PM PST Tuesday . Rain chances will decrease from north to south overnight with perhaps a few lingering showers around sunrise in parts of Monterey County. An upper level ridge will build over the the West Coast on Wednesday and Thursday, allowing for dry and warming conditions region-wide. There will likely be some overnight valley fog development, so there is some uncertainty in regard to maximum temperatures if, for example, low clouds/fog linger through the day in the North and East Bay Valleys. Locations with mostly clear skies in the afternoon will likely warm into the 60s with potential for middle and even upper 60s in parts of southern Monterey County.

Forecast guidance indicates another round of wet weather to return over the weekend to parts of northern and central California. At this point in time it appears to be a bit wetter than today's system, but the heaviest precipitation will be focused north and of our area. Looking ahead to next week, high pressure over the eastern Pacific will keep the storm track directed at the Pacific Northwest with northern California on the southern edge of these systems. The latest precipitation outlooks from the Climate Prediction Center gives much of the Bay Area and central California coast slightly favored odds of experiencing drier than normal conditions for both the 6-10 day and 8-14 day periods.

AVIATION. as of 9:55 PM PST Tuesday . For 06z TAFs. A weak frontal boundary continues to slide south across the forecast area bringing lower cigs, lower vsbys, as well as light rain to the Bay Area southward. Lingering low level moisture will keep patchy fog over Santa Rosa through tonight. Moderate southerly winds are expected ahead of the front. Winds will not see they typical switch to the west or northwest behind the front but rather turn variable or stay southerly. Winds will return to a more westerly direction Wednesday afternoon.

Vicinity of KSFO . MVFR/VFR conditions will prevail tonight with vcsh then tapering overnight. Moderate and locally gusty southerly winds will ease this evening becoming light and variable overnight then veer to the west Wednesday afternoon.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . MVFR/VFR cigs will prevail tonight with rain showers expected by this evening then tapering overnight. Light southeasterly winds will prevail overnight then veer to the west Wednesday afternoon.

MARINE. as of 8:56 PM PST Tuesday . Moderate to locally gusty southerly winds will persist ahead of a cold front that will continue to move through the region tonight. Winds will generally be light in wake of the frontal passage. A longer period northwest swell will peak midweek generating hazardous seas conditions for smaller vessels. Another long period northwest swell will then arrive later this week.

MTR WATCHES/WARNINGS/ADVISORIES. Tngt. SCA . Pt Arena to Pt Reyes 0-10 nm SCA . Pt Reyes to Pigeon Pt 0-10 nm SCA . Pigeon Pt to Pt Pinos 0-10 nm SCA . Pt Pinos to Pt Piedras Blancas 0-10 nm SCA . Pt Arena to Pigeon Pt 10-60 nm SCA . Pigeon Pt to Pt Piedras Blancas 10-60 nm

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.
