I was curious and had to do some research. Apparently South Dakota is the only state that does not play officially sanctioned high school softball (though that is about to change). And regarding South Dakota, the state's largest schools would prefer to play in the fall when the weather is better and there are fewer conflicts with club teams. The smaller schools prefer to play in the spring because of less competition for athletes vs other sports. (SD ultimately chose to play in the spring.)
There are currently only five states that play in the fall, though it seems there is growing support around the country for changing to a fall model. And Mississippi apparently has some schools that play in the spring and others who play in the fall.
The states playing "fall ball":
Colorado
Georgia
Missouri
Nebraska
Oklahoma
