San Jose is getting a brief dry start Sunday, with high clouds streaming over the Bay Area and Central Coast, including the San Jose area. Temperatures are around 55 degrees early, but rain is likely this evening as the front reaches the South Bay. The high should reach the mid to upper 60s as clouds increase.
According to the National Weather Service, Sunday carries a 95% chance of rain. The southern Santa Clara Valley, including San Jose, is forecast to receive 0.25 to 0.5 inches from the entire system. South winds of 7 to 13 mph may gust as high as 23 mph, so late-afternoon errands and outdoor plans could get blustery as the front arrives.
Sunday Night Brings The Steadier Rain
Rain is expected Sunday evening and continues overnight. San Jose should fall to around 47 degrees, and the wettest stretch could overlap with late-night travel and early Monday commutes.
Monday Stays Damp Before A Brief Break
Rain is possible during Monday's morning commute. The high should reach about 61 degrees, with less than a tenth of an inch expected during the day.
Monday night looks mostly clear but chilly, with a low near 40 and patchy fog after 1 a.m. Tuesday should then turn sunny after morning fog, reaching about 62 degrees — a one-day reset before the next system moves in.
Midweek Storm Could Pack More Punch
Rain chances jump again late Tuesday, with showers possible overnight, followed by more showers and rain Wednesday and Thursday. Thunderstorm chances are increasing, with probabilities as high as 20 to 30% Wednesday and Thursday. Winds are expected to be breezy, while highs reach 58 degrees Wednesday and Thursday.
The National Weather Service forecast discussion says the Wednesday-to-Thursday system could be more impactful than the storms arriving now, with current projections pointing to 2 to 3 inches of rain across much of the Bay Area and possible 30-to-40-mph gusts at valley floors. Because the ground may already be wet from the earlier rounds, residents should keep an eye on updated forecasts if they live near creeks, low-lying roads or areas that typically collect runoff.
Beach Plans Come With A Warning
For anyone heading west, a High Surf Advisory remains in effect through Tuesday morning, with breaking waves of 20 to 25 feet and occasional larger sets at favored spots. The National Weather Service is urging people to stay away from the water’s edge, rocks, jetties and piers, especially as rain and rough surf share the same weekend forecast.
