Area Forecast Discussion National Weather Service San Francisco Bay Area 116 PM PDT Tue Apr 7 2020

SYNOPSIS. Isolated to scattered rain showers will be possible over the Central Coast through midweek while mainly dry conditions prevail to the north. Temperatures will begin a gradual warming trend late in the week and into the upcoming weekend as conditions dry out region-wide.

DISCUSSION. as of 01:14 PM PDT Tuesday . Very light rainfall occurred over the far northern portions of Sonoma and Napa Counties earlier this morning as moisture continued to wrap around the mid/upper level low offshore. However, much of the region remains dry at this hour with an increase in cumulus given some daytime heating. Expecting some showers to begin to develop over interior portions of Monterey and San Benito Counties through the afternoon and potentially into the evening. Showers that do develop will move westward toward the coast and may impact valley and coastal locations. Thus, will continue to carry a slight chance of showers over much of the Central Coast through the afternoon, evening and even into late tonight.

Isolated to potentially scattered showers will remain possible over the southern portion of the region again on Wednesday and potentially into Thursday as the mid/upper level low off of the central and southern California coast slowly approaches the coast. This will also allow for seasonably cool conditions to persist over the southern areas while places such as the North Bay begin to experience a gradual warming trend through midweek. Mostly dry conditions will also prevail over the northern portion of the region through midweek.

The aforementioned mid/upper level low will push inland over southern California late in the week with conditions beginning to dry out region-wide. As it shifts inland this weekend, a warming trend is likely with more widespread mid/upper 60s near the coast and low/mid 70s over the interior. This trend is likely to extend into early next week as an upper level ridge builds just off of the West Coast.

AVIATION. as of 10:32 AM PDT Tuesday . for 18Z TAFs. This morning's low clouds have cleared out leaving some higher level clouds across the North Bay at about 10,000 ft AGL. Current obs show VFR conditions at all sites. Expecting VFR to prevail through this evening before models show a region wide increase in low level moisture overnight. MVFR/IFR cigs then forecast to prevail for most if not all sites through the rest of the taf period. Guidance suggests these low clouds may linger around the Bay Area into the early afternoon. Additionally, patchy fog may also return to the North Bay and portions of the East Bay. Generally light winds this morning turning onshore in the afternoon around 10-15 kt.

Radar shows some lingering showers over portions of Sonoma County this morning, though most areas should remain dry most of today. High res models show some possible showers returning tonight in the Monterey Bay Region south of San Jose.

Vicinity of KSFO . VFR through the evening before low clouds are expected to develop across the Bay Area and then persist through tomorrow morning. Low confidence on exact timing of cloud development. May be a few stray showers in the vicinity but otherwise dry conditions forecast. Variable winds again this morning to turn onshore this afternoon around 10-15 kt.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR into this evening before low clouds are forecast to develop over the Monterey Region. MVFR/IFR conditions then expected through the rest of the taf period. Additionally, high res models are showing showers developing late tonight and into early tomorrow morning. Light winds this morning with locally breezy SE winds down the Salinas Valley. Onshore winds this afternoon 10-15 kt.

MARINE. as of 08:29 AM PDT Tuesday . Northwest winds will increase across the coastal waters this afternoon and into tomorrow as an upper low slowly exits the region. Locally breezy winds are expected this afternoon and evening over the Monterey Bay and along the inner coastal waters from Pigeon Point to Point Pinos as well as overnight north of Point Reyes. A long period southwest and a long period west to northwest swell will arrive this morning and continue into tomorrow before decreasing.

MTR WATCHES/WARNINGS/ADVISORIES. Tngt. SCA . Mry Bay until 9 PM SCA . Pigeon Pt to Pt Pinos 0-10 nm until 9 PM SCA . Pt Arena to Pigeon Pt 10-60 nm from 9 PM SCA . Pt Arena to Pt Reyes 0-10 nm from 9 PM

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.
