Environment Canada has extended its snow squall warning in Perth and Huron counties for a second day.
The national forecaster says areas seeing the most squalls could see up to 15 centimetres of snow today, mostly centered in southern Huron County.
The OPP is again warning drivers to be careful as conditions can change rapidly going to near-zero visibility during heavy snowfall.
At least four more centimetres is expected this evening and tapering off after midnight.
