There are many TV weathercasters/meteorlogist who aren't very good. They may look good, be the right sex or race, but put little into their craft because they are either lazy or simply lack knowledge. One of the laziest TV meteorologist I've ever known was a legend in Texas and had a full degree from A&M. He simply did next to nothing, copied the National Weather Service forecast, and people thought he was great. Mainly because he had managed to survive and stayed on the air for so long.
There's another guy I know in a medium sized TX market who owns the market for weather. He never took a meteorology class, never was interested enough, and he also just re-words the National Weather Service. He is the king of TV weather in his town. He's good on the air and can tell a good weather story. People love him.
That said, Jeff is well respected in the world of TV meteorologist as a rising star. He has the looks and the knowledge. In the DFW area, you'd better know your stuff or the weather will run you over before long. I hope things work out for him in DFW.
