Key Factors
- 01 Special Weather Statement (4:17AM EST) warns of expanding patchy fog, possible freezing fog, and black ice from Friday snowmelt
- 02 Temperatures 28-31F from 6-9am, below or near freezing, so ice on roads and bridges is likely
- 03 Patchy fog forecast through about 9am, which may cause sudden visibility drops (no visibility values provided)
- 04 After 10am temperatures rise above 39F, precipitation chance is 0-2%, and winds are light at 1-6 mph
- 05 Evening temperatures fall from 44F to 37F by 11pm with no precipitation; overnight low near 31F, so a small chance of refreezing of any leftover wet spots late night or early Sunday

Recommendation
Avoid driving before about 9:30am if possible. Safer morning window: 10:00am-12:00pm, once fog has cleared and temperatures are above freezing. Safer evening window: 4:00pm-7:00pm, with dry roads and mild temperatures. If you must drive early, slow down, use low beams, and leave extra space for black ice and fog.
