1-minute Mesoscale Domain Sector GOES-17 “Red” Visible (0.64 µm) images (above) showed the dissipation of fog and stratus across the San Francisco Bay area on 03 September 2018. However, as most of the fog/stratus dissipated or retreated westward toward the coast in response to daytime heating, a persistent narrow ribbon of cloud was seen flowing east-northeastward through the Golden Gate and back into San Francisco Bay — with this flow of moist marine layer air leading to the formation of a new patch of low cloud as it encountered the higher terrain of the Berkeley Hills / San Pablo Ridge. This fog/stratus behavior was also observed using 1-minute GOES-14 Visible imagery in August 2016.
