PennDOT just issued the release below. It looks like we can expect more problems throughout the night. 

MONTOURSVILLE – PennDOT advises motorists in north central Pennsylvania that Columbia and Montour counties are experiencing snow squalls and high winds. Blowing snow is creating ice on the roadways, even those that already have been treated, including Interstate 80.

Motorists are asked to be alert and drive with caution. PennDOT crews will be treating roads in the region throughout the night.
