Thursday is when the pattern shifts again. The latest model runs slide the storm system west toward the Central Coast by Thursday morning. That should result in more clouds, gusty winds and an uptick in humidity on Thursday. It also likely means a more widespread risk of pop-up showers across the region, but that outcome depends greatly on the exact track of the storm system.<\/p>\n
Wednesday breakdown<\/p>\n
San Francisco: Wednesday should start with sunny skies across the city and lighter winds. By midmorning, clouds will start to build back in, leaving a mix of sun and clouds for the second half of the day. Temperatures should reach the upper 50s to low 60s in the Sunset and Richmond districts, with slightly chillier conditions at Ocean Beach and the Presidio. It won\u2019t be much warmer downtown, with highs in the mid-60s east of Twin Peaks and toward Mission Bay. Winds will generally be out of the west at 5 to 15 mph. Overnight should turn overcast, mild and a bit humid, with a chance of spotty showers and lows in the 50s.\u00a0<\/p>\n

North Bay: The North Bay should end up with the most sunshine in the region on Wednesday, courtesy of a drying offshore wind early in the day. The wind direction will become more onshore by afternoon, allowing more clouds to appear. Scattered showers will pop up again in Napa and Sonoma counties, where cloud cover is also likely to be a bit more widespread. Temperatures will generally be in the low 70s in Petaluma, Santa Rosa, Napa, Vallejo, Vacaville and Novato. San Rafael and Sausalito will be slightly cooler, with highs in the upper 60s. The shower threat will end after sunset, with partly cloudy, somewhat humid conditions overnight. Pockets of fog are possible, with lows in the low 50s.<\/p>\n
East Bay: \u00a0Wednesday\u2019s weather on the bayside part of the East Bay will be similar to conditions in San Francisco. A bright start will be muddled somewhat by increasing cloud cover during the afternoon. Temperatures will be slightly warmer than in San Francisco, with highs in the mid- to upper 60s in Richmond, Oakland and Hayward. An afternoon bay breeze will cool things a bit in Berkeley and Oakland. The interior East Bay should be warmer, with temperatures in the low to mid-70s in Walnut Creek, Dublin and Livermore. That area will also be more exposed to showers sliding down from Napa and Sonoma counties, especially around Martinez and Antioch. Clouds will build across the region overnight, with a chance of scattered showers and lows in the low 50s.<\/p>\n
Pacific Coast and Peninsula: The immediate coast should start Wednesday with sunshine, like much of the region. But onshore flow will help build cloud cover by early afternoon, leaving a mix of sun and clouds for the rest of the day. Temperatures should reach the upper 50s to low 60s in Half Moon Bay, Pacifica and Daly City. Winds won\u2019t be as strong as Tuesday, generally out of the northwest at 10 to 20 mph. The bayside Peninsula will be much less windy Wednesday, but will also see a mix of clouds and sunshine for much of the day. Temperatures will be a bit warmer, ranging from the low to mid-60s at SFO and San Mateo to the low 70s in Redwood City. Overnight will feature more clouds and some fog along the coast, with scattered showers developing in the predawn hours and temperatures in the low 50s.<\/p>\n
South Bay and Santa Cruz: The South Bay should hang on to mostly sunny skies into Wednesday afternoon before clouds start to develop. Temperatures will warm into the low to mid-70s in San Jose, Mountain View and Los Gatos. A few showers are likely to pop up late in the afternoon in the hills east of San Jose. Santa Cruz will likely battle more cloud cover Wednesday, keeping temperatures cooler, with highs in the mid-60s. Santa Cruz and the mountains will see partly cloudy skies overnight, with shower chances increasing in the mountains and lows in the low 50s. The South Bay will stay partly cloudy overnight, also with lows in the low 50s.<\/p>\n
