The snow has tapered and conditions are improving, but the system has pushed south out of the Canadian Prairies and into the U.S. Midwest.
"Winter storm warnings are widespread from North Dakota to Illinois," says Dayna Vettese, a meteorologist at The Weather Network. "Chicago is expected to see heavy snow with this system, something which is almost unheard of this winter in the Windy City."
Over 20 cm of snow is forecast in parts of Chicago, creating dangerous driving conditions and travel implications.
The city's airports cancelled close to 1,000 flights early Tuesday as the snow began to intensify through the morning hours.
Those with air travel plans are encouraged to check the flight status before heading out.
Emergency officials are also urging residents to avoid unnecessary travel and to keep cars at home if possible.
A number of schools closed for the day and city crews have deployed over 280 plows.
"A blocking high pressure system to the north will keep the storm south of Ontario," Vettese adds.
There is the potential however, for parts of the Maritimes to see snow later this week once the system gets south and east of the Great Lakes.
"At the moment, most guidance suggests the same blocking high pressure system will keep the storm south of the Maritimes and out to sea; A best-case-scenario for those longing for spring to arrive," says Vettese. "We will keep monitoring the latest model information and watch how this system continues to develop as it treks across the United States and sets its sights on the east coast and keep an eye on any potential impacts on Atlantic Canada."
Atlantic Canadians are currently dealing with a storm that's bringing upwards of 20 cm to parts of the region through Tuesday.
