Flood Watch for all of Western Massachusetts through Saturday afternoon. New precipitation amounts between a half and three-quarters of an inch possible. One to two inches of sleet and snow accumulation is expected. Mild temperatures and heavy rain could cause the ice to break up and form ice jams.

Parts of Calloway, Marshall, Trigg, Lyon, Christian and Hopkins Counties in Kentucky are expected to get close to a quarter inch of ice. Notice the colder air behind it - that's arriving Saturday.
