My husband and I are planning a road trip from central ohio to san antonio texas. I would like to go as far south as possible before heading west. I am nervous about the weather at this time of year. In louisiana and mississippi we are new to these areas and are not sure about traveling through that way or sticking to arkansas route. We are leaving ohio in mid-april and worry about heavy rain/thunderstorms in south. We won't let bad weather stop up necessarily but could avoid mississippi or lousiana if it is too risky this time of year.
