San Jose woke up today to a sharp slap of mid-30s cold and a thin glaze of frost in low-lying neighborhoods, leaving some shaded streets slick for the earliest commuters. Patchy fog hung on near the bay but is expected to break up through the morning as the sun returns and temperatures ease up. Drivers should keep an eye on exposed bridges and ramps in the early hours, when conditions are coldest and most slippery.
Afternoon Winds Pick Up
By afternoon, most neighborhoods should climb to around 60°F, though temperatures may dip a couple of degrees later in the day. South-southeast winds are forecast to strengthen to roughly 6 to 12 mph, with valley gusts near 20 to 25 mph. Exposed hills and the immediate coast could feel noticeably windier. Tonight, temperatures drop into the low 40s under partly cloudy skies.
Looking ahead, a stronger Pacific low is expected Monday night into Tuesday, bringing a widespread chance of rain and the potential for ponding in poorly draining areas, according to the NWS San Francisco.
Local Services and Commute
The combination of morning fog and chilly pockets can slow the commute, especially on shaded ramps and bridge approaches, so it is worth giving yourself a few extra minutes if you are heading out early. Santa Clara County lists warming centers and expanded shelter options and recommends calling 2-1-1 for help and locations. Outreach teams are active during inclement weather, and residents are encouraged to check the county's pages for up-to-date locations and hours, according to Santa Clara County.
What To Do
Dress in layers, protect sensitive plants and outdoor pipes, and bring pets inside during the cold overnight hours. If you see someone exposed to the cold, call local services or 2-1-1 for shelter options; for emergencies, dial 911. Before Monday’s commute, check back with local officials for final rain timing and any changes to wind or marine advisories.
