Recommendation
Best times to drive: morning 7:00 AM–11:00 AM, before storms build and while conditions are mostly sunny. For the evening, if travel is unavoidable, the safer window is before 5:00 PM; after 5:00 PM and especially 6:00 PM–10:00 PM, expect frequent thunderstorms and avoid driving if possible.
