Bill Short of Harveys Lake works on fixing a air leak in a Pennsylvania Department of Transportation plow truck Tuesday morning. With another snow storm on the way Tuesday night into Wednesday, PennDOT wanted to have as many trucks on the road as possible to deal with the expected messy commute. The area was to be waking up to several inches of snow and sleet this morning. After things clear up over the next few days, another possibly major storm might challenge road crews again Sunday and Monday. For the forecast, see page 10A.
