Recommendation
If you must drive, the safest window is this morning from about 9:00 AM to 2:00 PM, when conditions are currently dry and winds are light. For the evening, the least risky slot is early evening around 6:00 PM to 8:00 PM before overnight precipitation/ice risk increases; avoid late night travel, especially after 10:00 PM.
