San Francisco rolled out of bed today under cool, mostly cloudy skies, with spotty light rain and temperatures lingering in the upper 50s. Showers are expected on and off through the day and could leave parts of the city slicker than they look, with a daytime high near 67F before readings ease back in the afternoon. Another round of rain is slated to arrive mid-week and keep things cooler through Thursday, so it is a good day to grab the umbrella and pad your commute time.
Rain chances climb through the morning and hold in the 40 60% range through the afternoon, though most neighborhoods are only in line for light amounts, generally under a tenth of an inch. A stronger system moving in mid-Wednesday could wring out higher totals in the North Bay and coastal mountains, with mountain amounts roughly 0.25 60.60 inches while valley and peninsula totals trend lower. For the full forecast, see the National Weather Service.
Afternoon Commute And Safety Tips
Showers will leave stretches of pavement slick during both the morning and evening drives, so slow it down and leave extra stopping distance, especially on bridges and overpasses where things can feel dicey in a hurry. Transit riders may see minor delays on buses and Muni during the heavier showers, and pilots could run into brief bouts of lower ceilings that lead to short hold-times at SFO. Keeping wipers in good shape and headlights on while the rain hangs around is still the easiest way to stay visible and out of trouble.
Marine And Midweek Winds
Forecasters are calling for fresh southwesterly breezes today and tomorrow, but the real concern comes on the backside of the mid-week front, when strong northerly winds are possible Thursday and Friday with gusts up to 30 60-45 mph in favored gaps and ridges. That setup could create hazardous conditions for small craft on the bay and along the coast, so boaters will want to keep an eye on updates from the National Weather Service.
Weekend Outlook
By Friday, high pressure is expected to build in, flipping the pattern to an offshore flow and a quick warm-up: highs near the low 70s Friday and climbing into the upper 70s Saturday and Sunday, with mostly sunny skies. It should feel like a solid rebound for outdoor plans after the cooler, wetter stretch earlier in the week. If you are heading near the water or up into the hills, keep checking updated forecasts, since conditions can still vary from neighborhood to neighborhood.
