Forecasters say they expect two to three inches of snow to accumulate in parts of Alabama, with some isolated amounts of up to four inches.
Much of the state -- including large parts of northern and central Alabama --- was under a winter storm warning Thursday morning.
National Weather Service officials said periods of heavy snow will be likely, with the heaviest snow falling Thursday morning.
The weather service said dangerous travel conditions would continue through Thursday morning, with the possibility of bridges and overpasses becoming snow and slush covered.
The snow was moving into Alabama after heavy rain led to some flooding. Some areas of Alabama have received as much as six inches of rain since Sunday.
