Jack Frost is back with a vengeance in Huron County.

A snow squall warning is in effect for Blyth, Wingham, Goderich and all places in between.

Old Man Winter is expected to dump 15 centimeters of snow today.

Intense snow squalls will reduce driving visibility to zero.

Motorists travelling into the region should be prepared to drive on untreated roads as the snow piles up.
