San Jose rolled in today under clear skies and mild mid-50s temperatures, and the warmup will be quick. Inland neighborhoods are on track for mid 80s this afternoon, with sunshine holding strong and only light breezes for most spots. It will be the warmest day of the week before a cooldown kicks in, and overnight lows slide back into the low 50s tonight.
Afternoon Heat, Then A Cooldown On Deck
According to the National Weather Service, highs should top out near 86°F this afternoon, especially in inland areas. Tomorrow, trends a bit cooler with highs near 80°F. After that, a shortwave system will bring periodic chances of light rain from Tuesday, March 31, through Thursday, April 2. Daytime highs drop into the low 70s on Tuesday, and the morning commute from Tuesday through Thursday could feature patchy fog and brief showers.
Boaters, Commuters And Outdoor Plans
Coastal mariners will want to pay attention to Small Craft Advisories in effect for portions of the northern coast this afternoon into early Monday, with choppier conditions expected offshore overnight. Onshore, most neighborhoods will keep to light winds, but exposed ridges, bridges, and the mid-afternoon commute could run into gustier northwest breezes. If you are planning boating trips or outdoor events later in the week, it may be smarter to shift them to the morning hours or wait until the early-week system has moved on.
Quick Tips
Today is prime time to soak up the sun, but the afternoon heat will sneak up fast, so hydrate, pace outdoor chores and bring a hat and water if you are working outside. For the Tuesday morning commute after 5 AM, a light jacket or umbrella is a good idea, as cooler temperatures and the possibility of patchy rain or fog are likely.
