 When we get into trouble, especially with the more extreme heat stress events, is when we don't have those cooler nighttime temperatures. And so if I'm telling people to really watch for heat stress, it's when those nighttime temperatures are staying high as well because it doesn't allow cattle to get rid of that heat in the cooler hours. And certainly when we have multiple days in a row of that kind of weather pattern, that's really a time to be vigilant.
