Why do so many TV weather reporters have to say "and I am METEOROLOGIST John Doe"?

For years TV stations hired models and actors/actresses to read the weather reports on air. They knew nothing of weather and simply read the script provided. Now stations are hiring meteorologists (Actual weathermen) who not only read the weather but prepare the reports and analyze them. They want to make that perfectly clear so they are careful to identify themselves as meteorologists rather than your local weather girl or boy.

Jenna, you answered your own question. They say that because they want you to feel more confident with their predictions because they studied and obtained the title of meteorologist. TV stations can be very competitive when it comes to this popular feature of their broadcasts. Personally, I favor the wisdom of Mark Twain: "We all grumble about the weather, but" (dramatic pause) "--but--but nothing is done about it."

The weather is fickle. Because of that, weather forecast are wrong half of the time. To maintain some credibility, weather forecaster adds the fancy title before their name.

Because name recognition is what gets them more pay, better jobs...

Weathermen lead the list in becoming head anchors for news shows.
