Overcast or overcast weather, as defined by the World Meteorological Organization, is the meteorological condition of clouds obscuring all of the sky. Overcast, written as "OVC" in the METAR observation, is reported when the cloud cover is observed to equal eight oktas (eighths).
Sometimes clouds can be different colors such as black or white, but the word usually refers to grey. In some cases, it can be impossible to see distinct borders of clouds or the sky may be covered by a single type of cloud, such as stratus and the whole sky will be a dull white.
Periods of overcast weather can range from a few hours to several days. Overcast weather can also affect people suffering from seasonal affective disorder.
The same weather, when observed by pilots, might be referred to as (an) undercast.
Overcast! is the debut studio album by Minneapolis hip hop group Atmosphere, released in August 5, 1997 on Rhymesayers Entertainment. It's the only Atmosphere album to feature MC Spawn trading verses with Slug. Before the album's release, Spawn left the group due to conflicting motives.
The cover art is inspired by that of Judgment!, released in 1964 by jazz pianist Andrew Hill.
Overcast! is Atmosphere's breakthrough EP album, released in 1997.
