San Jose rolled in today under a blanket of low clouds and patchy fog, with early morning temperatures stuck in the mid-50s and visibility trimmed in some low-lying neighborhoods. The marine layer is expected to peel back by late morning, setting up mostly sunny skies and an afternoon high near 69°F.
Afternoon Winds Start To Flex
Once the sun breaks through, the breeze is forecast to shift to the northwest and stiffen, with gusts climbing into the upper teens along exposed ramps and ridgelines. It is the same overall pattern behind this weeklong warm-up, laid out in our earlier foggy-to-sunny warm-up preview that broke down the marine layer and morning fog routine. Drivers should watch for reduced visibility near bridges during the first part of the commute until the clouds finally thin.
Midweek Gusts Could Pack A Punch
Forecasters at the National Weather Service say a cold front will sweep through on Wednesday, followed by a strong high-pressure ridge that will tighten the pressure gradient and crank up northwest-to-northerly winds from Wednesday (March 4) through Friday. The agency is flagging the potential for gale-force gusts along the coast and over higher terrain, with Small Craft Advisories and Gale Watches already in place for parts of Monterey Bay and nearby waters.
Residents on exposed ridgelines are urged to lock down anything that can blow around, from trash cans to lightweight patio furniture, before the midweek winds arrive. Boaters are being advised to skip nonessential trips while the advisories are active.
Weekend Warm-Up On Deck
By the weekend, offshore northerly flow should dry things out and turn up the thermostat. Highs are expected to climb into the 70s on Saturday and Sunday, with some inland spots nudging into the mid-70s. Little to no measurable rain is on the books through at least early next week, which bodes well for outdoor plans even as low-level humidity drops. Nights will stay on the cool side, dipping into the 40s across higher terrain.
Commute And Safety Notes
Morning fog can knock down visibility on side streets and bridge approaches, so use low beams, back off the gas a bit and budget extra time for the first commute of the day. Ahead of Wednesday, secure trash cans, patio pieces and any other loose items that could turn into airborne projectiles once the gusts arrive.
If you have plans on the water or along exposed ridge tops, avoid unnecessary boating while advisories are posted and keep an eye on official updates and marine products from forecasters so the only surprise this week is how quickly the weather flips from gray to gusty to warm.
