The National Weather Service in San Francisco has projected a warming trend taking place today that will extend through Tuesday, followed by a possible influx of rainfall around mid-week. This upcoming Wednesday, parts of the San Francisco Bay Area may see an increase in rain activity. However, the likelihood of any area receiving more than 0.10 inches of rain remains below 25%. It is critical for residents to be mindful of this forecast as the week progresses.
The North Bay and sections of the San Francisco Peninsula experienced light rain earlier on Sunday morning, with rainfall amounts typically below 0.05 inches, "likely a result of the dissipating frontal boundary" across the region, according to the National Weather Service in San Francisco. While the rain is anticipated to taper off by late morning, temperatures are expected to come near to average later in the day with an upper hand of 70s to low 80s across interior regions and a difference of low-to-mid 70s within San Francisco and the Bay Shoreline.
As for the longer-term outlook, cooler and moist conditions will likely culminate early Wednesday with the approach of another upper-level trough. This could result in light rain or showery conditions, particularly in the North Bay. However, the rainfall amounts have been adjusted downward from previous estimates, reducing expectations for the week's rest.
While the region prepares for a scattered drizzle and a potential mid-week shower, beachgoers, specifically in Sonoma and Marin counties, are advised to be vigilant. As the National Weather Service Forecast Office in San Francisco, CA, mentions, there is "a moderate risk for sneaker waves and rip currents late Monday afternoon into Monday evening." Visitors are cautioned to avoid areas like jetties and maintain awareness of the tides to steer clear of sneaker waves that can suddenly surge up the beach with powerful currents.
