Key Factors
- 01 Hourly temperatures of 59–79°F and winds of 2–9 mph indicate no forecast freezing or sustained strong-wind hazard.
- 02 Rain chances remain 0–1% through 8pm, then increase to 20% at 10pm and 28% at 11pm.
- 03 The Flood Watch highlights possible heavy rainfall and flooding late tonight into September 13; strongest storms could produce 1–2 inches in a short period.
- 04 The overnight forecast places thunderstorms after midnight and patchy fog after 2am on September 13, rather than during today's daytime hours.
- 05 Watch timing is inconsistent: its structured end is midnight, while its headline says noon September 13. Visibility measurements and wind gust forecasts are not provided.

Recommendation
Prefer 9–11am or 6–8pm today, all times EDT (UTC−04:00). The early-evening slot is comparatively safer, not guaranteed storm-free; check updated alerts before leaving. Avoid discretionary travel from 10pm–midnight as rain risk increases, especially if the trip extends into the stormier overnight period. Never drive through flooded roads.
