Recommendation
For a morning trip, prefer 7–11 AM EDT. For an evening trip, prefer after 8 PM EDT, but check conditions before leaving because showers or thunderstorms may continue into the night. If possible, avoid the higher-storm-risk period around 5–7 PM; use caution on wet roads and stay hydrated.
