They are as much a part of the American television experience as daytime soaps, canned laughter and cheaply produced infomercials.
But if one angry meteorologist gets his way, "auto-cutie" weathergirls may become a thing of the past.
Kyle Hunter, an award-winning weatherman who claims to have spent 20 years as a forecaster in Southern California, says his applications for presenting jobs at local CBS stations were ignored or rebuffed solely because he was not a good-looking, 20-something female.
His lawyer, Gloria Allred, said it was one of the first times a man had claimed unfair discrimination, under Californian employment law, on the grounds of his gender.
Hunter, who describes himself in legal papers as "over the age of 40 years", alleges that his treatment by the CBS channels KCBS and KCAL amounted to age discrimination. He is seeking "unspecified" damages.
