Key Factors
- 01 The Dense Fog Advisory describes visibility as low as one quarter mile until 8:00 AM EDT; its headline and description provide this end time despite inconsistent structured timestamps.
- 02 Hourly precipitation chances are 0–2%, with temperatures of 45–58°F from 7:00 AM through midnight, indicating no forecast freezing conditions.
- 03 Forecast winds are 2–13 mph; gust data is not provided.
- 04 Hourly visibility measurements are missing, so fog clearance at 8:00 AM cannot be confirmed.

Recommendation
Avoid driving before 8:00 AM EDT while the fog advisory applies. Prefer 9:00–11:00 AM EDT for morning travel, provided visibility has improved, and 6:00–8:00 PM EDT for evening travel. If fog persists, delay travel where possible; otherwise slow down, use low-beam headlights, and increase following distance.
