Hazardous winter conditions are expected to blow into Sudbury Wednesday.
Environment Canada has upgraded its winter storm watch to a winter storm warning.
An intensifying low pressure area approaching the Great Lakes will bring a few rounds of rain tonight. However, a cold surge of Arctic air arriving early Wednesday will intensify the storm, and change the rain to snow.
The snow will fall heavy at times on Wednesday, and accumulate 10 cm by evening with another 5 - 10 cm likely Wednesday night. Total amounts of 15 - 20 cm are expected before it ends late Wednesday night or early Thursday morning.
Some freezing rain is also likely during the transition from rain to snow. Some blowing snow can also be expected as brisk northerly winds develop during the day Wednesday.
Prepare for quickly changing and deteriorating travel conditions.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to [email protected] or tweet reports to #ONStorm.

A winter storm watch is in effect for Greater Sudbury and vicinity.
An intensifying low pressure area approaching the Great Lakes tonight will bring a few rounds of rain today and tonight.
A cold surge of Arctic air arriving early Wednesday will quickly change the rain to snow along with some patchy freezing rain.
The snow will fall heavy at times and accumulate 10 centimetres by evening with further accumulations Wednesday night. Total amounts in excess of 15 centimetres are possible before it ends later Wednesday night or early Thursday morning.
Visibility may be suddenly reduced at times in heavy snow. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Poor weather conditions may contribute to transportation delays.
Winter storm watches are issued when multiple types of severe winter weather are expected to occur together.
