No update to the forecast this evening. Slight rain chances persist in far northern Sonoma County near the coast as an upper level trough axis begins pushing through overnight and the associated surface cold front begins pushing south through our area. Surface winds will begin to increase after sunset especially along the North Bay coast at first and higher elevations inland. The stronger surface winds will persist through Friday, however the spatial and temporal extent of the winds aren't quite there for a wind advisory attm, though some isolated inland peaks and coastal locations may see occasional gusts of 45 MPH or higher by tomorrow afternoon into the evening hours.

Mostly sunny skies have returned to the region this afternoon, except for coastal locations of Marin County and the San Francisco Peninsula. As such, temperatures are forecast to warm up to around 10 degrees F above seasonal averages in the warmest interior valleys has a short wave ridge builds ahead of an approaching mid/upper level trough.
A rather dry cold front is forecast to move through the region on Wednesday morning with increasing north to northwest winds developing by the late morning and more so by the afternoon. There remains a slight chance for light rain across far northern Sonoma County, yet not expecting much if any measurable rainfall. The strongest winds tomorrow will remain over the coastal waters, along the coastline, and in the higher terrain with gusts up to 35-45 mph. However, at this time, we do not anticipate a Wind Advisory as widespread coverage does not appear to be great enough. Temperatures Wednesday afternoon will be near seasonal averages in wake of the frontal passage with clearing skies.

Moderate winds are forecast to resume Wednesday night into Thursday and will limit the cooling potential. As such, expecting upper 30s to lower 40s across the interior with low to upper 40s across the remainder of the region. Winds increase once again Thursday afternoon with similar directions and speeds as previously mentioned in the short term discussion.
Friday and Saturday will begin a warming trend as the mid/upper level low pressure moves from the Great Basin into the Intermountain West. This will result in offshore flow, especially for the higher terrain across the region. By Sunday afternoon, temperatures are forecast to be between 10 to 20 degrees above normal resulting in more widespread Minor HeatRisk. This will be as a mid/upper level cut off low develops off the coast of Baja California.
The forecast ensembles show continued ridging across the region which supports the Climate Prediction Center's above normal temperatures and below normal precipitation in the 8-14 Day Outlooks.

A moderate northwest breeze tonight increases to a strong northwest breeze on Wednesday and near gale force winds by Thursday. These winds will build very rough seas of 12 to 15 feet across exposed waters Thursday through Friday. Both of these impacts will result in widespread hazardous conditions across the coastal waters. Seas and winds will abate for the coming weekend, but hazards to small craft persist in the northern outer waters with strong north winds and rough seas.
