When is there going to be a tornado in central Louisiana?

It is not known. It is impossible to predict a tornado for a specific location until it actually occurs. Regional tornado potential can be predicted up to a few days in advance, but even then there is a lot of uncertainty. A forecast could say tornadoes are likely, but cannot say for certain if a tornado will touch down in a particular area such as central Louisiana. As of August 22, 2013 there is little to no tornado potential in the southern United States for the next few days.
