A winter storm is a type of precipitation in which the dominant varieties of precipitation are forms that only occur at cold temperatures, such as snow or sleet, or a rainstorm where ground temperatures are cold enough to allow ice to form (i.e. freezing rain). In temperate continental climates, these storms are not restricted to the winter season, but may occur in the late autumn and early spring. Also, there are very rare occasions that they form in summer, though it would have to be an abnormally cold summer, such as the summer of 1816 in the Northeast United States of America. In many locations in the Northern Hemisphere, the most powerful winter storms usually occur in March and, in regions where temperatures are cold enough, April.
Snowstorms are storms where large amounts of snow fall. Snow is less dense than liquid water, by a factor of approximately 10 at temperatures slightly below freezing, and even more at much colder temperatures. Therefore, an amount of water that would produce 2 cm (0.8 in.) of rain could produce as much as 20 cm (8 in.) of snow. Five centimeters of snow (2 in.) is enough to create serious disruptions to traffic and school transport (because of the difficulty to drive and maneuver the school buses on slick roads). This is particularly true in places where snowfall is uncommon but heavy accumulating snowfalls can happen (e.g., Atlanta, Seattle, London, Memphis, Canberra). In places where snowfall is common, such as Buffalo, New York, Montreal, and Minneapolis, such small snowfalls are rarely disruptive, though snowfalls in excess of 15 cm (6 in.) usually are.
A massive snowstorm with strong winds and other conditions meeting certain critera is known as a blizzard. A large number of heavy snowstorms, some of which were blizzards, occurred in the United States during the early and mid-1990s, and the 1993 "Superstorm" was manifest as a blizzard in most of the affected area.
Large snowstorms can be quite dangerous: a 15 cm (6 in.) snowstorm will make some unplowed roads impassable, and it is possible for automobiles to get stuck in the snow. Snowstorms exceeding 30 cm (12 in.) especially in southern or generally warm climates will cave the roofs of some homes and cause the loss of power. Standing dead trees can also be brought down by the weight of the snow, especially if it is wet or very dense. Even a few inches of dry snow can form drifts many feet high under windy conditions.
Snowstorms are usually considered less dangerous than ice storms. However, there are secondary dangers of the ambient snow that may result from a snowstorm. Mountain snowstorms can produce cornices and avalanches. An additional danger, following a snowy winter, is spring flooding if the snow melts suddenly due to a dramatic rise in air temperature. You can also die from things like hypothermia, infections brought on by frostbite, car accidents due to incliment weather or fires due to alternative heating methods used in a power blackout caused by a storm.

A snowstorm means it is going to snow more than 2 inches and it is going to be heavy at times.

A snowstorm has snow, it is windy, overcast and the snow falls for quite a while. If it is cold enough it piles up on the ground.
Just like a rainstorm has rain
A hail storm has hail
A thunderstorm has thunder (and lightning and rain)

Loads of wind and the snow drifts very quickly with the wind. If it is bad then it can block doors and so on. New York is in a snowstorm right now.

Snow is crystallized rain and falls in flakes. If you know what a rainstorm is then you know what a snowstorm is. Crystallized rain with huge amounts of accumulation.

The sky is heavy with clouds. The wind is blowing. Snow is falling so thick at times you can't see anything (like a thick fog). It is usually not severely cold.
