San Jose is getting one more pleasant afternoon before a midweek weather change moves in. High clouds will remain over the area throughout Tuesday, with patchy morning fog, partial sunshine and a high near 71.

Fog should clear before 9 a.m. Light winds in the morning will give way to moderate onshore winds during the afternoon and evening. Temperatures will ease back toward the upper 60s by late afternoon, setting up a mild but increasingly cloudy evening, according to the National Weather Service.

Rain Arrives After Dark

Showers could reach Bay Area sites between 5 a.m. and 11 a.m. Wednesday, with a 30% chance of rain and a low near 50. Rainfall should be light, with less than a tenth of an inch possible, but patchy fog may make the overnight drive murky.

Wednesday brings the wetter part of the forecast, with showers increasing across the Bay Area and rain chances rising. Thursday carries a 20% to 40% chance of rain across the Bay Area as the system moves out.

A Brighter Saturday, With Rain Possible Sunday

Friday looks like the reset button: patchy morning fog should give way to sunshine and a high near 71. Saturday is expected to be mostly sunny with a high around 73, while a slight chance of rain returns Sunday.

The updated timing sharpens the midweek rain outlook from Monday's Hoodline forecast, which had already flagged a cooler turn and overnight showers. For local plans, Tuesday afternoon remains the best outdoor window, while drivers should be ready for lower visibility early Tuesday and slick spots during the overnight rain.
