I don't want to drive in shitty conditions for a new years eve party
Is the weather bad? What about the conditions are making you uncomfortable.
I don't want to drive in the risk of getting into a traffic jam or an accident
If the conditions are that bad, you shouldn't go. You could get into an accident.
I think it will be fine. The weather channel says the conditions are fine to drive on a highway.
If you feel comfortable getting there you should go but remember there is no party so good you should risk your safety for.
