Special weather statement in effect for:

Stratford – Mitchell – Southern Perth County
Wingham – Blyth – Northern Huron County
Rain changing to snow as winter weather returns later today.
Rain is expected to develop today as a strengthening low pressure system approaches the Great Lakes.
As the low pressure system passes by just to the south of the region later today, brisk winds will begin to pull in much colder air from the north. Thus rain will change over quickly to snow later this afternoon or early evening. Total snowfall amounts of 10 to 15 cm are possible by Friday morning.
In addition, strong and gusty northerly winds may result in areas of blowing snow and very poor visibility tonight.
Conditions should improve Friday morning as the low pressure area moves away across Pennsylvania to the east coast. Although the worst of the conditions should occur during the night, the Friday morning commute will likely still be impacted.
Please note that considerable uncertainty remains regarding the exact evolution of this system. If higher snowfall amounts than currently forecast appear more likely, snowfall warnings may be required.
