Key Factors
- 01 Dense Fog Advisory (visibility as low as 1/4 mile) was in effect until 8:00 AM EDT; it has since expired
- 02 No precipitation expected (0-2% chance all day)
- 03 Temperatures well above freezing (45-58F daytime, low near 42F overnight) so no ice risk
- 04 Winds light, max around 13 mph from the N/NW - no significant crosswind concern
- 05 No visibility data provided after the fog advisory window, and high morning humidity (82-86%) could allow patchy residual fog

Recommendation
Driving is safe today. Best morning window: 9:00 AM-12:00 PM EDT, after the fog advisory expires and sun burns off any residual patches. Best evening window: 5:00 PM-8:00 PM EDT, dry with light winds. If you must drive before 8 AM, slow down, use low-beam headlights, and increase following distance.
