Safer time to drive from Seattle to Bellingham in certain conditions

I’m from Seattle and I want to do something with my family on Saturday night in Seattle but have something up here in Bellingham at 10 am on Sunday. I’m a night person who goes to bed at 1 am at the earliest and my parents are suggesting I drive up the morning of. I did this once before and I was late to the event I had to be at. Also looking at the forecast it will be cold but not raining. Wondering what other people think considering these. Is it safer for me to drive up leaving Seattle between 10-11 PM when I’m not in a rush and I’m pretty much awake or leave Seattle on Sunday morning between 7-8 AM when I’m half asleep and most likely in a rush?
