Area Forecast Discussion National Weather Service San Francisco Bay Area 344 AM PST Sun Jan 19 2020

SYNOPSIS. High pressure building over the West Coast will result in dry and seasonably cool weather conditions through the weekend. Light rain is possible starting Monday, with higher chances of precipitation developing by Tuesday. Mostly dry conditions are then expected for the remainder of next week, with rain possibly returning next weekend.

DISCUSSION. As of 3:39 AM PST Sunday . High clouds continue to stream over the area, and temperatures are running a few degrees warmer than yesterday at this time with readings ranging from the upper 30s to upper 40s. Currently, the only observation indicating fog is Byron, in the East Bay, reporting a visibility of less than 1/4 of a mile. Highs today are expected to be a few degrees than yesterday as the upper ridge axis moves over the state. Highs from the mid 50s to mid 60s are expected.

An approaching upper level trough will bring increased cloudiness to the area on Monday leading to rain chances later on Monday. This trough is forecast to bring light rain to most of the forecast area late Monday night through Tuesday. A separate disturbance is forecast to bring moisture into Southern California ahead of the upper trough, and the ECMWF still indicates some precip chances across the southern counties including Monterey and San Benito by Monday afternoon, before the upper trough arrives. Rain chances will then increase from north to south late Monday night and Tuesday morning as the main frontal system arrives. Rainfall is forecast to be mostly light, but may be moderate at times in the North Bay. Most rain should end by late Tuesday, although a few showers may linger into Tuesday night. As much as three-quarters of an inch or rain is forecast in the North Bay through late Tuesday, with generally a third of an inch of less expected elsewhere in our forecast area.

Mostly dry conditions are expected through the remainder of the week with an upper ridge pushing the moisture to the north. The next rain chances look to be late next weekend when another trough approaches the area.

Generally light winds this morning with locally breezy conditions down the Salinas Valley. NW to NE winds this afternoon.

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.
