Key Factors
- 01 Dense Fog Advisory in effect until 10:00 AM EST, visibility one quarter mile or less
- 02 Widespread fog forecast 6-10 AM with humidity 89-96%
- 03 Rain likely late afternoon/evening, peaking 4-6 PM (86-91% chance), causing wet roads and reduced visibility
- 04 Patchy fog returns after about 8 PM and overnight
- 05 Temperatures 36-42F all day, above freezing, so icing is unlikely; overnight low near 34F could allow isolated slick spots on untreated surfaces late
- 06 Winds calm to 2 mph, no crosswind risk
- 07 No numeric visibility values provided in the hourly data, so fog intensity after 10 AM is uncertain

Recommendation
Driving is generally manageable but avoid the pre-10 AM dense fog window and the 4-6 PM heavy rain window. Safer morning slot: 10:00 AM-12:00 PM, when fog lifts and rain chances drop to about 32%. Safer evening slot: 8:00-10:00 PM, after the rain ends (only 20-24% chance), though patchy fog means using low beams and extra following distance. If you must drive in the fog, slow down, use headlights (not high beams), and leave plenty of distance ahead.
