San Jose is waking up to light rain early today, with temperatures near 48°F at Mineta San Jose International Airport. Thunderstorms are on track to roll through before mid-morning, bringing brief heavy downpours and gusty winds that could slow the commute. Highs should top out near 51°F before temperatures slide later in the day.
Morning Thunderstorms And Gusty Wind
The morning storm window packs most of the drama. Thunderstorms may bring lightning, small hail, and locally heavy rainfall, with inland wind gusts in the 30 to 35 mph range and stronger gusts on exposed ridgelines and along the Central Coast. The most active period is expected before about 10 AM, then the system breaks up into scattered showers through the afternoon and evening. For the latest forecast details and advisories across the Bay Area, head to the National Weather Service San Francisco.
Friday Morning Cold And Frost
A Cold Weather Advisory is in effect from 1 AM to 9 AM PST tomorrow, with lows dropping into the low to mid 30s across the Santa Clara Valley and nearby hills. Patchy frost and pockets of fog are possible during the advisory period, which could create slick spots for early-morning drivers and damage sensitive plants. For warming locations and shelter options, see the City of San José.
Weekend Outlook
Friday looks colder and mostly dry, but rain is expected to return Saturday, with additional chances into Sunday and early next week. Minor urban and poor-drainage flooding is possible if heavier bands set up, and temperatures are forecast to rebound into the 60s by Monday while unsettled conditions linger.
How To Stay Safe
Plan on extra time for wet roads: slow down, leave more following distance, and keep headlights on during heavy rain and gusty conditions. Stay off beaches while advisories are active, secure loose outdoor items, and check on elderly neighbors and pets; warming centers and overnight shelter options are available if you need a warm place. Keep an eye on local forecasts and alerts before heading out and avoid unnecessary travel during the strongest gusts or downpours.
