Recommendation
Safest morning window is after 10 AM once temperatures climb above 44F and rain chances drop. Safest evening window is roughly 5-8 PM (48-43F) before temperatures fall toward freezing later at night. Use extra caution on shaded or bridge surfaces before 9 AM and after 10 PM due to frost/freeze risk.
