"With temperatures below 21 degrees, we have crews that arrive at 4 a.m. to begin starting and warming the buses," said Mike Horsely, director of Fleet Operations for the Fort Worth Independent School District. "The biggest issue in cold weather is that diesel fuel thickens, but we don’t expect the cold to last long enough for that to be an issue."
Finally, don't forget your pets. Even animals that live outdoors most of the year should be brought inside during times of inclement weather.
"If you're cold, your outdoor pets are cold," said Jonnie England, director of Animal Advocacy for the Metroplex Animal Coalition. "The body temperature of dogs and cats is just a little higher than a human's, so even though they're wearing 'fur coats,' they're still going to suffer in weather this cold. If it's not feasible to bring the pets inside the house, at the very least, they should be set up in a draft-free garage or storage building with plenty of dry, clean bedding."
