David Tillman Yo! Dude! What's doin' out yonder? Count on David Tillman to tell you, straight up. Houston has its multitudes of manic meteorologists -- from the pretty-haired, fashion-plate "personalities" to the stern high school principal types -- all dividing those dew-point decimals and spewing that nonsensical nomenclature about upper-level troughs. Tillman is pleasantly low-pressure, even when the systems are high-pressure. And he's got stellar credentials, including an Emmy for snowstorm coverage at his old TV station in Memphis. Tillman is content to deliver the forecasts on weekends, mornings or any other time he's needed, then to retire to his family of three. He keeps life -- and his forecasts -- simple. Like a front moving in from Canada, he's naturally cool.
