Post script: Daughter is off to school, stocked up on groceries and gasoline. Dad work done.
The weather report for her trip isn't great, but it isn't horrible either. Quasi-freezing rain right around the Scranton area, and as she travels south, no precipitation until about Leigh County, where it's raining. If she takes her time she will be fine, although we had better get a call once she gets there to confirm her safe arrival.
