San Francisco starts Wednesday under mostly cloudy skies, with temperatures climbing into the upper 60s before rain showers become possible later in the day. The unsettled stretch continues into Thursday, but a sunny and warmer weekend is already lining up behind it.

Showers Arrive By Afternoon

A chance of rain develops after late morning Wednesday, with the best odds from the afternoon into the evening. The city could see brief showers and less than a tenth of an inch of rain, while temperatures peak near 69 degrees before slipping back into the mid-60s.

Rain chances diminish overnight. Winds at SFO will likely remain variable for much of Wednesday, with low confidence in their direction.

Thursday Stays Cool And Damp

Thursday brings another chance of showers, mainly before 4 p.m., along with a cooler high near 65 degrees. Rainfall should remain light in San Francisco, although the National Weather Service says thunderstorms and locally heavier downpours are possible in parts of the Central Coast. The National Weather Service also expects temporary visibility problems where stronger showers move through.

Sunny Weekend On Deck

The rain threat fades Friday, when mostly sunny skies and a high near 69 degrees return. Saturday should be sunny and warmer at about 73 degrees, followed by a mostly sunny Sunday with a high near 75.

For anyone planning outdoor time, the forecast improves quickly after Thursday: Friday through Sunday is expected to stay dry, with daytime highs mostly in the low to mid-70s. Overnight lows will remain seasonably cool, generally in the low to mid-50s.
