Recommendation
Morning slot: 8 AM to 11 AM offers the best conditions with rising temperatures, sunny skies, and light winds. Evening slot: 4 PM to 6 PM is also safe with partly sunny skies and calm winds. Avoid driving after midnight as rain/snow mix begins and conditions deteriorate rapidly into the winter storm.
