Flying via Chicago during winter is gambling

This morning when I woke up I checked the weather in Chicago.... bad news.... high winds with snow. I would fly via Chicago to Seattle and if the weather gets worse, I would be stuck in Chicago over the night. Luckily, my plane arrived to Chicago without problems but my flight to Seattle is delayed for 1 hour 30 minutes.... so I will be in Seattle after midnight, but at least I get there.
