Area Forecast Discussion National Weather Service San Francisco Bay Area 1003 AM PST Sat Dec 14 2019

SYNOPSIS. Another frontal system will drop southward over the region late in the day bringing a renewed chance for light precipitation. Cooler and drier conditions are then forecast from Sunday into early next week. Unsettled weather conditions are expected to return for the latter half of next week and will potentially continue into next weekend.

DISCUSSION. as of 9:20 AM PST Saturday . A band of high clouds is currently moving across the central part of the state, otherwise, look for mostly sunny skies today most areas. Current temperatures are running cooler than yesterday at this time, mainly across the North and East Bay areas where there was less cloudiness overnight. Current readings are in the upper 40s to mid 50s. A front will move onshore along the Oregon and northern California coasts by this afternoon. This will spread precip chances into the North Bay by this evening, petering out as it moves inland. Rain chances will extend down the coast to Point Sur, with QPF numbers on the low side with a quarter of an inch or less expected. Showers to end by Sunday morning with high pressure building over the state over the next several days. This will bring cooler nights and seasonably mild days through Tuesday. Much cooler overnight conditions are expected with widespread 30s likely across the interior valleys Sunday morning and more so by Monday morning when lower 40s to even upper 30s will be possible near the coast. Daytime highs are expected to be generally in the 50s.

The forecast models continue to indicate a shift towards an unsettled weather pattern by the middle of next week as a upper level trough and a cut-off low approach from the west. Meanwhile, a much deeper plume of moisture will advect inland over Oregon and far northern California by the latter half of next week. Thus, while details remain limited at this time, there will be the potential for periods of rain late in the week and into next weekend.

AVIATION. as of 10:03 AM PST Saturday . For 18z TAFs. Drier air at the surface has arrived with cigs rising. Skies are also clearing in the drier air with cumulus buildup over terrain, mainly south of the Golden Gate. Overall, cloud cover should continue to decrease through early this afternoon before clouds increase again late this afternoon and evening. A trough and weak front will pass through this evening with a few scattered showers developing. Any rain will be light and lift from the trough should keep cigs mainly VFR, but brief periods of MVFR are possible with showers.

Vicinity of KSFO . VFR conditions through the period. SCT cumulus may develop near the terminal, mainly to the south and west of the approach. Isolated showers will develop between 00z and 06z this evening with a BKN layer at 4000-5000 ft as the front moves through. Breezy northwest winds with gusts 20-25 kt through the evening.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . Mainly VFR conditions today with SCT to BKN cumulus clouds 2500-4000 ft. Scattered along a front will arrive around 03z and end overnight.

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.
