San Jose residents woke up to a frosty start on Saturday morning, with temperatures dipping into the mid-30s and a thin layer of frost covering some low-lying neighborhoods. Drivers should be cautious of slick conditions on exposed bridges and ramps during the early commute. Temperatures are expected to climb to around 60°F by the afternoon, but strong south-southeast winds of 6-12 mph, with gusts up to 25 mph, will make it feel noticeably cooler. A Pacific low-pressure system is also expected to bring a chance of rain to the area on Monday night into Tuesday.

Why it matters

The combination of morning fog, chilly temperatures, and gusty winds can create hazardous driving conditions and impact the daily routines of San Jose residents. Providing information about the weather conditions and any available community resources can help people prepare and stay safe during the inclement weather.

The details

Patchy fog near the bay is expected to clear as the sun returns, but drivers should still be cautious of slick conditions on exposed bridges and ramps during the early morning hours. Temperatures are forecast to reach around 60°F by the afternoon, but the strengthening south-southeast winds of 6-12 mph, with gusts up to 25 mph, will make it feel noticeably cooler. A stronger Pacific low-pressure system is expected to bring a widespread chance of rain to the area on Monday night into Tuesday, with the potential for ponding in poorly draining areas.
