Where do winter storms start along?
Winter storms begin with moist air rising up into the atmosphere, just like other types of storms. Rising air is common at a cold front, where warm air is lifted above cold air and is necessary for cloud formation and precipitation.
Where do winter storms occur in Canada?

What weather conditions do winter storms bring?

Which states get the most ice storms?
The highest frequency is found over Vermont, eastern and southern New York, eastern Pennsylvania, and far northwest New Jersey, where some locations averaged 4-5 ice storms.
How are ice storms formed?
Ice storms are caused by freezing rain. The raindrops move into a thin layer of below-freezing air right near the surface of the earth, allowing them to freeze on contact to the ground, trees, cars and other objects.
Why do ice storms occur in Ontario?
The Great Ontario Ice Storm Arrives
It was a result of separate weather conditions converging – one of them a large stationary Arctic high-pressure area situated over Hudson’s Bay, another a low-pressure weather system with warm air originating in Texas, was settling in southern Ontario.
Why are there so many storms in Ontario?
Great Lakes Region Climate
In the winter, bitterly cold Arctic air masses move southward into the region, and the polar jet stream is often located near or over the region. This causes frequent storm systems that bring cloudy, windy conditions and rain or snow.
