The next challenge I've accepted as part of my "Jeanne Tries" series is one I have (a bad) experience with from my time in broadcasting school. Forecasting with a green screen is a difficult challenge, trying to point at things on a wall that aren't really there. Meteorologist Dana Zimmer from Good Morning Northland on WDIO offered a quick crash course for me and a couple other folks from the station and sent us out to do a forecast for Grandma's Marathon week. Check it out! How did I do?
