The National Weather Service is forecasting a gradual warming and drying trend across the region, with San Jose reaching about 81 degrees tomorrow and 82 degrees on Tuesday and Wednesday, according to the National Weather Service. Thursday should remain mostly sunny, near 81 degrees, before temperatures ease back to the upper 70s on Friday and Saturday.

Cool Nights And Building Breezes

Overnight lows will stay comfortable, generally between 57 and 59 degrees through the week. Afternoon and evening northwest winds will gradually become more noticeable, reaching up to 13 mph by Friday.
