stratus

Generally grey cloud layer with a fairly uniform base, which may give drizzle, snow or snow grains. When the Sun is visible through the cloud, its outline is clearly discernible. Stratus does not produce halo phenomena except, possibly, at very low temperatures. Sometimes Stratus appears in the form of ragged patches. - https://www.wmocloudatlas.org/stratus-st.html
