Meteorologists use sophisticated computer models that analyze atmospheric conditions like temperature, pressure, humidity, wind speed, and direction. They look at satellite imagery, radar data, and ground observations from weather stations all over the region. For Shelbyville, this means they're tracking systems moving in from the west, potentially bringing changes from the plains, or from the south, which can bring moisture from the Gulf of Mexico.
