Key Factors
- 01 Dense Fog Advisory until 8:00 AM EDT, with visibility one quarter mile or less; the alert's end time field is inconsistent, but the text states 8 AM

- 03 Slight chance (21-23%) of showers and thunderstorms from 2-4 PM, which could briefly bring heavy rain or lightning
- 04 Slight chance (15-19%) of rain showers from 6-8 PM and again from 10 PM to midnight
- 05 Winds are light to moderate (up to 12 mph, gusts to 22 mph), which is not a significant crosswind concern
- 06 Temperatures of 52-78F mean no ice or freezing risk
- 07 Visibility figures are not given in the hourly data, so fog clearing times are inferred from the forecast descriptions

Recommendation
Avoid driving before 9 AM if possible because of dense fog. If you must drive then, slow down, use low-beam headlights, and leave extra following distance. The best morning window is 10 AM to 1 PM, with sunny, dry conditions and light winds. The best evening window is 8 PM to 10 PM, which is mostly cloudy with the lowest evening rain chance (10-14%). If you drive between 2 and 4 PM, watch for isolated thunderstorms and pull over safely if heavy rain or lightning occurs.
