Recommendation
Safer morning driving window: 9 AM–11 AM, when it is dry, above freezing, and winds are light. Safer evening driving window: 6 PM–9 PM, when precipitation chances remain near 0% and winds are very light; avoid unnecessary travel after midnight and especially after 4 AM Sunday as winter storm impacts begin.
