San Francisco's Tuesday morning conditions are not specified in the available forecast, leaving the day's weather details open.

The National Weather Service page identifies the forecast office but does not provide a Tuesday high, wind speeds, sky conditions or rain chances for San Francisco.

Afternoon Winds Pick Up

The available forecast does not identify where or when Tuesday's strongest winds will occur. Wednesday will bring temperatures in the mid-to-upper 60s, so a light jacket may be more useful than the calendar suggests.

Fog Returns Overnight

Tuesday-night cloud cover and temperatures are not specified in the available forecast. The broader outlook mentions an overnight marine layer but does not specify its extent, timing or drizzle potential around San Francisco.

The broader outlook says the marine layer will hang tight for most of Wednesday.

Calmer, Seasonable Weekend Weather

The broader outlook points to calmer, seasonable weekend weather.
