Key Factors
- 01 Special Weather Statement (NWS Mount Holly) warns of patchy fog, possible freezing fog, and black ice from Friday snowmelt this morning
- 02 Patchy fog forecast 6am-9am with temperatures 28-31F and humidity 92-96%, so freezing fog and icy patches are likely
- 03 Temperatures rise above freezing by 9-10am (35F) and reach about 49F in the afternoon, melting any ice
- 04 Precipitation chance is near zero (0-2%) all day
- 05 Winds are light (1-6 mph), so there is no crosswind concern
- 06 Evening temperatures fall to 37-41F by late evening. They stay above freezing through midnight, but the overnight low near 31F brings a renewed refreeze risk after midnight
- 07 No explicit visibility data provided, so fog severity is inferred from the forecast text

Recommendation
Avoid driving before about 10am if possible because of freezing fog and black ice. If you must drive then, slow down, use low beams, and leave extra following distance, especially on bridges and shaded roads. The best morning window is 10:30am-12pm, when fog has cleared and temperatures are near 39-42F. The best evening window is 5pm-8pm, while temperatures remain in the low-to-mid 40s. Watch for refreezing on wet spots late at night.
