Recommendation
Safer morning driving window: after 10 AM, especially 10 AM–12 PM, when rain chances drop and temperatures are in the mid-40s. Safer evening driving window: 6 PM–9 PM, when conditions are dry and temperatures remain above freezing; avoid travel near/after midnight due to the Freeze Warning and falling temperatures.
