San Francisco woke up damp and mild today, with temperatures hovering near 59°F as scattered showers moved through the city. Those showers, along with a chance of thunderstorms, are expected to continue today, and a stronger, more organized storm is on track for tomorrow, bringing the highest potential for heavier downpours.

Timing And What To Expect
Forecasters say shower and thunder chances peak today, then ramp up again tomorrow afternoon and evening, when the bulk of the moisture is expected to arrive. Tomorrow is set up to be the wettest day, with guidance pointing to about a half to three quarters of an inch of rain for most of the city, and locally higher totals in coastal and hill neighborhoods. The nearby coastal ranges could pick up an inch or more. Thunderstorms could bring lightning, brief heavy downpours, erratic gusts, and small hail, with wind in favored spots possibly topping 20–25 mph…..
