SUN: And now, here’s a 15-year-old Baltimore County student with the weather

Tanner Cero turns on a small lamp that barely registers to the naked eye but adds just the right amount of illumination to the green screen that backdrops his bedroom wall. Tanner, 15, is now suited up and ready to start his broadcast.

“You’d be surprised,” the Middle River 10th grader says just before airtime. “The littlest light helps.”

Tanner Matthew Cero is chief forecaster at TMC Weather, his own weather service, named after his initials. From this modest bedroom “studio,” the Chesapeake High School student broadcasts a daily weather forecast to legions of fans. TMC’s Facebook page has about 12,000 followers. Foot’s Forecast, a weather page started by Perry Hall Middle School science teacher Richard Foot that Tanner says he now runs, has over 100,000.

Tanner’s fans include Baltimore County Councilman David Marks, students at the Catholic High School of Baltimore and a legion of loyal commenters. Local meteorologists like Tony Pann, Justin Berk and Justin Chambers have been mentors too, he says. But Tanner didn’t get into the forecasting biz for the fame, he says. It was far more personal.
