The weather gods will show no mercy.
After a winter of mostly lake-effect snow squalls in our neck of the woods, the first major winter storm of the season is about to run roughshod over southern and parts of northern Ontario.
Environment Canada says snow beginning late this afternoon will be at its heaviest overnight, dumping between 20 and 30 cm and a little less in the Greater Toronto Area (GTA)
Winter storm and snowfall warnings have been posted from North Bay to the GTA, while a freezing rain warning is in effect for the Windsor and Chatham areas in southwestern Ontario.
