San Jose is starting Thursday under widespread stratus and cool, below-normal conditions, but the gray is expected to give way to mostly sunny conditions by afternoon. Temperatures should rise during the day before cooling overnight, setting up a quick turn toward warmer weekend weather.
Sunny Afternoon Follows Cloudy Start
Clouds will thin through the morning, with onshore or west-northwest breezes later in the day. Deep-layer drizzle remains possible Thursday. Patchy fog may return after 1 a.m. Thursday night as temperatures dip to around 56 degrees.
Weekend Warmup Arrives Fast
Friday brings a retreating morning marine layer and a 5-to-10-degree warming trend. Northwest winds could gust as high as 21 mph, especially during the afternoon. Saturday looks like the warmest day of the weekend, with morning fog clearing before 9 a.m. and sunny skies pushing temperatures to about 84.
Cooler Sunday, Then Another Warmup
Sunday backs off slightly to a high near 78, with patchy fog possible between 7 and 9 a.m. Monday and later temperatures remain low-confidence, with models showing a possible warming followed by cooling.
The National Weather Service’s San Francisco office describes Thursday as the coolest point in the pattern, followed by warming Friday through the weekend before another marine-layer influence brings some cooling Sunday; the National Weather Service expects the overall stretch to remain dry. A light layer will still earn its keep during early walks, commutes and school drop-offs.
The latest forecast spells out a sharper weekend rebound, while temperatures later in the period remain low-confidence. For San Jose residents, the practical version is simple: cloudy mornings, sunny afternoons and a little more heat waiting just around the corner.
