With the standard (non-digital) models, you might want to put something over it to keep the rain off as much as possible, over the dial. Mine live on a covered porch, and I'm not sure I would ever subject mine to a rain storm without cover. I mean, it's pretty weatherproof, but it is still an electric appliance! Water & electricity don't often make good company. Maybe put it under the eves, or just inside an open garage door?
