According to CBS LA Meteorologist Evelyn Taft, Southern California is preparing for a weekend of coastal fog. This typical weather pattern occurs when cool ocean air meets warmer inland temperatures, causing fog to form along the coast. Residents and visitors in Los Angeles and Orange County should anticipate reduced visibility, especially in the early morning and late evening. The fog is expected to be densest in coastal communities, gradually clearing as the day warms up. This phenomenon, known as the marine layer, significantly influences Southern California's climate.
