San Jose woke to cloudy skies Sunday morning, with a mild afternoon ahead. The clouds should thin at times before returning later in the day, while temperatures top out around 77 degrees. It is a quiet start to a week that will end noticeably hotter.
The National Weather Service expects mostly cloudy conditions Sunday. A few patches of light drizzle may develop around the marine layer late Sunday night or early Monday, but no meaningful rainfall is expected.
Foggy Start, Then A Sharper Warmup
Patchy fog could appear after 5 a.m. Monday before stratus retreats after morning. Warming resumes Tuesday as ridging returns. Coastal and bayside areas will stay cooler than inland San Jose during the warmup.
The bigger jump arrives Wednesday, when inland highs are forecast in the 90s, continuing Thursday. The outlook continues through Friday. Mornings are expected to stay cool.
Sunday Plans Look Mild Before The Heat Arrives
For Sunday outdoor plans, expect comfortable temperatures, light winds and a mostly cloudy sky, with the best chance for brighter breaks around midday and early afternoon. The more important planning note is the quick shift later in the week: warm, dry weather builds from Tuesday through Thursday. No local weather advisories are listed for San Jose.
