San Jose is starting today on a gray note: mostly cloudy skies, a muggy feel, and temperatures hovering near 55°F as a Pacific system edges into the South Bay. Showers and a few thunderstorms could bubble up this afternoon, with the rain turning more persistent and widespread tonight.
Afternoon Storm Chances
Scattered showers and thunderstorms are expected this afternoon into the early evening, with a high near 65°F and south-southeast winds around 5 to 18 mph, gusting up to about 30 to 31 mph. Any stronger cells could drop brief heavy downpours and lightning, so outdoor plans may get cut short. According to NWS San Francisco, the chance of precipitation is around 70% during the day.
Evening Rain Band And Commute
A narrow but organized band of rain is expected to sweep through this evening, bringing steadier rain and stronger southerly gusts just ahead of the front. That timing is not great for the evening drive, with slower commutes and standing water in low-lying spots a good bet. Build in extra travel time and do not try to power through flooded lanes. For live road conditions and closures, check Caltrans QuickMap or call 511 before heading out.
Rain Totals And Short-Term Outlook
By the time the system winds down tomorrow, rainfall totals will be uneven across the region. Lower elevations can expect roughly 0.75 to 1.10 inches, interior hills may collect about 1.25 to 1.75 inches, and some coastal peaks could see 2 inches or more. Tonight alone could drop a half inch or more in several spots, with a brief period of stronger gusts ahead of the front.
The National Weather Service notes that the system should ease from tomorrow until next Monday, with drying conditions and a gradual warmup into next week. For the latest updates, check forecasts from NWS San Francisco.
Boating And Beach Advice
Small craft advisories are up for parts of Monterey Bay and the nearby coast, with choppy seas and gusty winds making things rough for smaller recreational boats through much of today. If you were planning to head out on the water, it is safer to hold off until advisories are lifted and you have read the latest marine statements.
Quick checklist: bring rain gear today, secure any loose outdoor furniture, expect a slower evening commute, and avoid driving through standing water. We will update this post if any watches or warnings are issued.
