Recommendation
Preferred morning driving window: 9 AM–11 AM EDT, after the Frost Advisory ends and temperatures rise above 40°F. Preferred evening window: 6 PM–9 PM EDT, when conditions are dry and temperatures remain 43–46°F. Use extra caution before 8 AM on shaded or elevated surfaces, and avoid unnecessary travel after midnight as freezing conditions develop.
