No NO NOOOO.
The weather is not to blame. The weather is never to blame unless it's a freak storm that pops up out of nowhere, grabs your car, and flings it into another car.
Sure, it's the nice way to not say "Hey that ____ should have pulled over instead of risking his life", but it doesn't make it true. If you're flying down the highway and can't see the vehicles ahead of you, the weather's not to blame when you hit them.
