GOES-16 (GOES-East) nighttime Cloud Thickness and daytime “Red” Visible (0.64 µm) images (above) displayed a narrow band of marine stratus/fog that was moving southward along the East Coast of the US on 23 March 2021. Plots of Ceiling and Visibility showed that some sites along the coasts of New York, New Jersey and Delaware experienced a reduction in visibility to 1/4 mile at times. The Cloud Thickness product (a component of the Fog/Low Stratus suite) indicated that portions of this feature were 350-400 meters (1150-1300 feet) thick.

With ample illumination from the Moon — which was in the Waxing Gibbous phase, at 68% of Full — a NOAA-20 VIIRS Day/Night Band (0.7 µm) image at 0600 UTC or 2:00 am EDT (below) showed the stratus/fog feature as it was beginning to moved southward along the DelMarVa coast.
