Zonal flow over the region tightens as an upper level low develops and slides into the Great Basin by Wednesday. Quiet weather is on tap, with light offshore flow today. Though winds increase late tonight and peak Wednesday morning for the North Bay, Bay Area, and Santa Cruz Mountains. These winds will have gusts around 30-45 mph, with locally higher gusts possible on higher terrain in the North Bay mountains. Conditions will dry out some; however, given earlier rainfalls this year fuel moisture should mitigate fire weather

Winds begin to wind down during the late morning and afternoon hours on Wednesday. After that fairly quiet weather remains on tap as upper level ridging noses into the region. Ensembles hold weak ridging through the weekend, perhaps even into early next week. This matches the Climate Prediction Center's 8-14 day outlook which has us leaning above normal for temperatures, with near normal or just below normal chances for precipitation.

It's a great day for VFR pilots to get up! Outside of some lingering patchy morning fog spilling over from the Central Valley, clear skies will dominate today. Winds will be gentle and shift from offshore to onshore in the afternoon. The synoptic pattern becomes drier through the TAF period. Strong high pressure is building over northern Nevada while coastal CA troughing strengthens. This offshore, high-to-low pressure gradient will bring dry offshore flow that will discourage any low level clouds. This dry air should also mix down to limit radiation fog Wednesday morning. Although even with low dew points that's not a guarantee with enhanced surface cooling under clear skies and long December nights.
Vicinity of SFO, Guaranteed VFR conditions through the day. The biggest question mark is when exactly surface winds will shift from offshore to onshore and back. The TAF currently has onshore winds driven by the sea breeze from 23Z to 10Z, but with weak forcing, there is a lot of wiggle room there.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, VFR conditions across the region today. Winds will remain light and variable at MRY. SNS will have moderate drainage flow continue through the early afternoon before a weak sea breeze should flip the wind direction. There is a better chance for ceilings to form at MRY and SNS overnight as the offshore wind is focused further north and a weak marine layer may have a brief chance to develop there.

Persistent high pressure over the Eastern Pacific will cause the moderate to strong northerly breeze to continue through the week. Rough sea heights will subside by Thursday as westerly swell abates.

A Beach Hazards Statement remains in effect for the coastline from Sonoma County to Monterey County through 10 PM PST Wednesday evening. Breaking waves 10 to 14 feet, with long lulls of 10 to 20 minutes or more between largest sets can be expected. Some of the favored break points may exceed 20 feet at times. Forerunners will be 18+ seconds with heights of 2-5 feet into tonight resulting in the greatest risk for sneaker waves. This combined with high astronomical tides in the morning hours will increase the aforementioned risk. Sneaker waves can unexpectedly run significantly farther up the beach than normal, including over rocks and jetties. Rip currents are typically more frequent and stronger in the vicinity of jetties, inlets, and piers.
