Halloween-goers may need to pack umbrellas, spooky or otherwise.

The latest forecast as of late Sunday afternoon predicts showers may drench San Francisco again Sunday evening, with a “slight chance” of thunderstorms.

It may also rain again Monday afternoon, according to the National Weather Service, and rain is “likely” in the evening for Halloween night.

But though there is a chance of rain on a mostly cloudy Tuesday morning, the service advised, the skies will be mostly clear by evening.

Cloudy weather is expected Wednesday on, with no word of rain for midweek or the late week yet.
