San Jose started today under clear skies and a crisp 54°F, but it will not stay chilly for long. Temperatures are expected to climb fast, topping out near 84°F this afternoon with mostly sunny skies and light breezes. The dry, mild stretch will hold through the weekend, then a shift in the weather pattern brings the first shot at measurable rain to the Bay Area by next week.
Afternoon Warmup and Commute
Expect a big temperature swing today. Morning lows in the low 50s are set to jump into the low to mid 80s across inland spots by midafternoon. Valley winds should stay gentle at around 2 to 6 mph, with northwest breezes picking up later in the day. With the marine layer almost completely absent, neighborhoods that typically stay on the cooler side will warm up more than usual. If you are heading out for errands or a walk, plan for a warm afternoon and keep an extra layer handy for the cooler start and evening cooldown.
Weekend Outlook
Tomorrow is on track to be sunny, with highs near 82°F, and next Sunday looks like the peak of this stretch, with many inland areas pushing into the mid-80s. Along the coast, a very shallow marine layer may develop early tomorrow, bringing some patchy drizzle that should fade by midday.
Rain Returns Early Next Week
The National Weather Service expects a pattern change late Monday, with rain likely moving in next Tuesday, March 31, and continuing through next Thursday, April 2. Coastal ranges and the Central Coast are favored for the highest totals, with some areas potentially picking up about 0.5 to 1 inch or more. Inland valleys are more likely to see only a few tenths of an inch, according to the National Weather Service. That discussion also notes that offshore breezes produced pre-dawn gusts of 35 to 45 mph across higher North Bay ridges early Friday, although wind impacts in the valleys should remain modest. If you have outdoor projects on your list, this weekend is your window, and it would be wise to have an umbrella ready starting Tuesday.
