- 03 Daily forecast notes storms could produce heavy rain; overnight rainfall amounts of 1 to 2 inches are possible.
- 04 Heat Advisory until 8 PM EDT with heat index values of 95 to 100, which can affect driver alertness and safety during breakdowns or delays.

Recommendation
Best morning driving window: 8 AM–12 PM EDT, before thunderstorms and the Flood Watch period. If evening travel is unavoidable, the least-bad window is around 5 PM–6 PM EDT before the highest rain probabilities, but avoid travel from 6 PM–midnight EDT due to likely heavy thunderstorms and flash-flood risk; never drive through flooded roads.
