A stationary front lies right over S. Central Florida. This front combined with some surface moisture will allow for a few showers and a possible thunderstorm mainly in the late afternoon and through the evening on Saturday.
Sunday the front begins to lift to the north as a warm front, this will bring some cloudiness and a chance for showers through the day. The majority of the rain will be inland but I still expect to see some coastal action as well.
Monday the cold front and low pressure system moves closer and keeps the clouds around with a good chance for mainly showers at anytime during the day with a small chance for a few isolated thunderstorms.
