Key Factors
- 01 Dense Fog Advisory until 10:00 AM EST: visibility one quarter mile or less, hazardous driving (hourly forecast shows widespread fog 6-10 AM).
- 02 Precipitation chance rises to 66-88% between 8-10 AM, so fog and rain overlap during the morning commute.
- 03 Steady rain from about 4-8 PM (79-91% chance, 0.1-0.25 in expected) will reduce visibility and create wet roads during the evening commute.
- 04 Patchy fog returns from about 8 PM and again at 11 PM.
- 05 Temperatures stay 36-42F during the day, so ice risk is low, but the overnight low near 34F warrants caution on untreated surfaces late.
- 06 Winds are light at 0-2 mph, so there is no crosswind concern. Actual visibility values beyond the advisory were not provided, which adds some uncertainty.

Recommendation
Avoid driving before 10 AM. If you must drive in the fog, slow down, use low-beam headlights, and leave extra following distance. Safer windows: about 10:30 AM-12:30 PM in the morning/midday, when fog has lifted and rain is lighter, and about 8:00-9:30 PM in the evening after the steady rain ends (watch for patchy fog). Avoid 4-8 PM if possible because of steady rain.
