Mostly clear sky conditions are expected by this afternoon across all of the Bay Area and north Central Coast as high pressure over the eastern Pacific builds and shifts eastward. However, the presence of the exiting trough will keep conditions slightly below seasonal averages. As a separate mid/upper level cut-off low moves into the northern portion of the Intermountain West, we will have a brief period of moderate offshore winds (locally strong in the highest peaks) across the North Bay Interior Mountains with northeasterly gusts to around 30-40 MPH late this evening and into Saturday morning. Again, the highest peaks have the potential to exceed 50 MPH. Elsewhere across the Bay Area, offshore winds will be weaker but still exist in elevations generally above 1,000 feet. Given the offshore flow aloft over much of the Bay Area, have lower confidence of fog development again overnight. That said, cannot rule out fog again over the North Bay Interior Valleys just before sunrise Saturday morning.
Saturday and Sunday afternoon maximum forecast temperatures will warm to near to slightly above seasonal averages as high pressure continues to build over the eastern Pacific. However, minor coastal flooding looks to return to bayshore locations along the San Pablo Bay, San Francisco Bay, and Monterey Bay on Saturday and then low- lying areas along the Pacific Coast Monday during and around times of peak high tide. This is due to thermal expansion of the warm waters generated by El Nino and astronomical high tides through at least the middle of next week.

Temperatures drop to slightly below normal for much of next week as a series of troughs impact the Pacific Northwest. Thus, we are not expecting any precipitation until late in the week and into the following weekend (October 30th-November 1st). This is the time frame in which the Climate Prediction Center's 6-10 and 8-14 Day Outlooks give the Bay Area and north Central Coast a 50-60% probability of above normal precipitation which is more typical for a strong El Nino year as the Pacific jet stream drops farther south over southern California. Be sure to stay up-to-date with the latest forecast information from trusted sources.

Surface high pressure will build into the Great Basin tonight and Saturday morning. The WMC-SFO pressure gradient will steepen to near 10 mb while the RDD-SAC pressure gradient will steepen to around 3 mb. Offshore winds will develop in response to these gradients, bringing in additional drying tonight and Saturday. Decreasing water vapor will allow nocturnal radiational cooling to steepen and residual humidity in the boundary layer from recent rain may cool to saturation producing patchy low clouds and fog /IFR-LIFR/ tonight and Saturday morning. Radiative cooling will also produce cool air drainage winds to the coastline tonight and Saturday morning. Onshore winds closest to the coast will redevelop Saturday, but not until later in the afternoon. Otherwise VFR is forecast.
Vicinity of SFO, VFR. Northwest wind shifting to light northeast wind by early Saturday morning. West to northwest wind near 10 knots late Saturday afternoon and evening.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, VFR. West to northwest winds 5 to 10 knots shifting to east to southeast winds 5 to 10 knots tonight and Saturday morning. Northwest winds near 10 knots late Saturday afternoon and early evening.

Fresh to locally strong northerly winds will continue this afternoon and evening. Near gale force to gale force gusts remain possible across the far northern outer waters, with strong gusts south of Pigeon Point. Northerly winds will continue to decrease and become moderate by Saturday morning and then prevail through the upcoming week. Rough seas are expected today and tomorrow across the outer waters with wave heights peaking between 10 to 13 feet. Moderate seas prevail Sunday through much of next week.
