  • HOW A BLIZZARD FORMS

Blizzards form when two air masses of different
temperatures collide. Winter storms usually form
when an air mass of cold, dry, Canadian air moves
south and interacts with a warm, moist air mass
moving north from the Gulf of Mexico. The point
where these two air masses meet is called a
front. If cold air advances and pushes away the
warm air, it forms a cold front.

Blizzards are long-lasting storms and has very
strong winds with intense snowfall. You need
three things to have a blizzard cold air at the
surface, lots of moisture, and lift. Warm air
must rise over cold air.

How Long a Blizzard Lasts
Blizzards usually last only a day in one
location, since the wind usually moves them along
quickly. Sometimes, though, you get a cut-off
low, which is a storm system that is cut off
from the wind. These cut-off lows can create
blizzards (particularly in mountainous regions)
that can last as long as a week.

blizzard to describe a snow storm. Previously,
the term blizzard referred to a cannon shot or a
