Poor winter driving conditions are expected tonight and into Friday morning.
Environment Canada has issued a special weather statement for Chatham-Kent, Sarnia-Lambton and much of Southwestern Ontario.
An Alberta clipper with yet another Arctic cold front will sweep southeastward across the regions tonight, bringing an area of snow with it.
Total snowfall amounts with this system will be fairly modest in the 2 to 5 cm range for most, although 5 to 10 cm is quite possible in a few locales near the Great Lakes and in Southwestern Ontario where the weather system appears to have a little more moisture.
Strong and gusty southwesterly winds will cause drifting and some blowing snow in many areas, with visibility occasionally reduced to 1 kilometre or less in exposed areas.
Driving conditions will deteriorate tonight with the snow.
Poor winter driving conditions from occasional low visibility in snow and blowing snow, as well as some accumulating snow on untreated roads will likely extend into the morning rush hour on Friday in many areas.
Motorists should allow extra time to reach their destination.
The cold front will move through to the southeast of the Lower Great Lakes on Friday morning, taking the area of snow with it.
The public is advised to monitor future forecasts and warnings as warnings may be required or extended.
