High clouds are across the region, and cloudy conditions are likely to persist over San Jose through Thursday. Inland valley temperatures are in the lower to middle 40s. The day will turn mild with a high near 72. Rain is unlikely to reach the surface, though it cannot be ruled out. Weak offshore flow in the morning should shift to weak onshore flow later in the day.
Thursday Warmth Gives Way To A Cooler Weekend
Friday looks gloomy and cloudy, followed by a cooler Saturday with patchy fog before 9 a.m. and a high near 66. Saturday carries a small chance of light rain, while Sunday should rebound to sunny skies and a high near 67. Overnight temperatures will dip into the mid-40s, so Halloween plans may call for more layers than anyone hoped.
Unsettled weather remains possible across the broader Bay Area. The National Weather Service keeps a slight chance of regional showers in play from late Saturday into Sunday, while the city’s point forecast stays mostly dry. Monday should warm back near 71 before a small rain chance returns Tuesday.
Thursday’s Hoodline forecast called for a cooler Halloween Saturday, with a high near 64. The newer forecast still favors a cool, mostly dry Saturday afternoon, with fog in the morning and a low around 45 Saturday night.
Coastal Flooding Remains A Shoreline Concern
San Jose itself is inland and is not under the coastal flood advisory, but readers heading toward the Bayshore or Pacific Coast should pay attention. The National Weather Service expects high tides roughly 1.9 feet above normal Thursday afternoon, 1.6 feet Friday afternoon and 1.1 feet Saturday afternoon, with the regional advisory lasting through Saturday. Low-lying roads, waterfront paths and parking areas could see minor flooding around high tide.
For outdoor plans, Friday offers the brightest and most comfortable afternoon, while Saturday is shaping up as a classic Bay Area mix of fog, clouds and a chilly evening. Sunday looks sunnier, but not especially warm, making this more of a jacket-weather weekend than a washout.
