TROON, Scotland -- Here's an updated weather forecast for the next four days at the 145th Open Championship: It might rain. It might not be the kind of light, fluffy rain that feels refreshing on a lazy afternoon, either. It might be hard, heavy droplets pounding down from the heavens that force everyone to run for cover. Or it might not even feel like it's barreling down from the sky, instead swept up by the wind and forming the type of sideways rain that so often permeates this golf tournament. It might do this for an extended period of time every day.
