(Cincinnati)--A Winter Storm Warning has expired for much of the Tristate with up to five inches of snow on the ground in some places.

The heaviest snow fell across Northern Kentucky, Southern Hamilton County and Clermont County. The other problem was the falling temperatures that potentially makes salt used to treat the streets ineffective. Wind chill values are expected to fall below zero today.

Hundreds of schools cancelled classes and the snow forced Metro to detour several bus routes, as the buses are unable to navigate the Hackberry Loop, Liberty Hill and Bender Road.

Campbell County and Grant County were placed under a Level Two Snow Emergency early this morning, advising people not to travel unless it was absolutely necessary.

By late afternoon, many community's snow emergencies had been dropped, or lowered.

Kentucky Transportation Cabinet expected to send most of their road crews home after the evening rush.

ODOT says for the first 20 days of this year, they've used twice as much salt on the roads in southwest Ohio, as during the same period last year, at a cost of over $3.8 million.
