Key Factors
- 01 The weather statement warns of reduced visibility and possible black ice from refrozen snowmelt this morning.
- 02 From 6–9 AM EST, patchy fog coincides with temperatures of 28–31°F; fog is forecast to end by 9 AM.
- 03 Temperatures rise to 39–42°F by 10 AM–noon, but air temperatures alone cannot confirm that road ice has melted.
- 04 Winds remain light at 1–6 mph, with only 0–2% hourly precipitation chances through midnight.
- 05 Evening hourly temperatures remain above freezing. The overnight low of 31°F extends into March 1 and does not establish freezing conditions before midnight.
- 06 Visibility distances and road temperatures are unavailable. The alert's identical start and end timestamps do not establish a reliable hazard expiration.

Recommendation
Avoid driving before 9 AM EST if possible, especially 6–9 AM. Safer slots are 10 AM–noon and 6–8 PM EST, provided roads are free of residual ice. If morning travel is necessary, slow down, use low beams, and leave extra following distance; do not assume ice disappears immediately at 9 AM.
