Area Forecast Discussion National Weather Service San Francisco Bay Area 913 PM PDT Tue Mar 31 2020

SYNOPSIS. Dry weather conditions with seasonable temperatures are forecast for the remainder of the week. Rain chances and cooler temperatures return by the upcoming weekend and will potentially continue into early next week.

DISCUSSION. as of 9:10 PM PDT Tuesday . An upper low near Vancouver Island ushered in a moderate northwest flow over northern California. Upper level high off the central and southern California coasts brought lighter winds and warm temperatures to the southern half of the state. Inland highs today warmed into the low to mid 70s from the Santa Clara Valley south. Low clouds kept things cooler around the Bay Area except for some adiabatic warming in the North Bay valleys.

The upper low will shift south tonight and Tuesday. This will strengthen the northwest flow which will help to clear out the low clouds later tonight. Cooler temperatures are expected Wednesday followed by warmer weather Thursday and Friday as the low moves inland.

Models continue to indicate a fast moving storm system on Saturday followed by a stronger system on Sunday. Models coming into better aggreement on timing of the first system with rain spreading into the North Bay Saturday morning and into the Monterey Bay Area Saturday afternoon. There could be a short break Saturday night before the second system arrives on Sunday with unsettled weather into Monday. In terms of total QPF amounts The GFS is a little wetter than the ECMWF. Forecast amounts Saturday through Monday are 1/2 to 1 inch across the area with 1-2 inches in the mountains and parts of the North Bay . and less amounts in southern Monterey and San Benito counties. Beyond that longer range models show dry weather returning.

AVIATION. as of 4:42 PM PDT Tuesday . for 00z TAFs. A few midlevel clouds around 2,000 ft AGL, but otherwise VFR around the Bay Area. Strong onshore winds with occasional gusts persists. Expect winds to ease overnight for inland terminals, but will remain breezy along the coastline. Skies should remain mostly clear. Winds will remain onshore through the TAF period, with Wednesday seeing stronger winds and wind gusts in the afternoon with mostly MVFR/VFR cigs.

Vicinity of KSFO . Winds remain onshore around 12-15 knots this evening. A few clouds pass through around 2,000 feet, but otherwise VFR, which is forecast through the night. Winds will ease, but only slightly and remain breezy through the evening. As conditions remain VFR on Wednesday, onshore winds prevail and once again strengthen in the afternoon with gusts 20-25 kts.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR with breezy onshore winds. Winds will ease overnight. MVFR/VFR conditions forecast, but possible periods of low cloud build up in the Salinas Valley overnight. Wednesday is forecast to be VFR with stronger onshore winds, particularly closer to the coast where KMRY is expected to have gusts over 20 kts.

MARINE. as of 08:23 PM PDT Tuesday . Northwesterly winds strengthen Wednesday as a low pressure system over the Pacific Northwest moves inland, providing gale force winds. A prevailing mixed swell with a building short period and steep northwest swell and a light southwesterly swell will continue through the 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.
