The atmosphere moves in masses. When two masses collide they are called fronts. When a cold air mass goes into the land occupied by a warm mass it makes a cold front. The opposite makes a warm mass.
cold fronts are heavier than warm fronts
It separates hot air masses and cold air masses
Cold dry air from the Rockies/Canada meet warm moist air from the Gulf.A winter storm forms when warn moist air from the Gulf of Mexico meets col dry air from Canada meets eachother and makes something known as a front.
Blizzards can happen where there is winter so it could be anywhere in the world where it is cold enough and a storm comes in.
as they collide the cold and warm front pushes the occluded front to become 3 air masses.

what happens in cold and warm masses pressure
Thunderstorms form when 2 air masses collide the most common is a cold dry airmass and warm humid moist airmass. Those air masses collide and if the conditions are right the moisture will rise into the atmosphere and condense into clouds and eventually will build up enough to become thunderstorms.
Storms are usually associated with fronts, especially in warm weather, with cold air fronts collide with warm air, and the upheaval of air produces thunderstorms in advance of the front.
The common statement is that tornadoes develp when warm and cold air collide, but this grossly oversimplifies what is going on. The collision of warm and cold air masses is not the direct cause of tornadoes nor, is it completely necessary. If there is enough instability in the warm air mass, the collision can lead to the formation of thunderstorms. If a few other conditions are right these storms might go on to produce tornadoes. However such storms may also form wheredry air pushes into moist air. They can sometimes even form from convective storm systems without any colliding air masses.
A boundary between two air masses of different temperatures and humidity is called a front. If a cold front meets a warm front head on, there is a possibility for a violent storm.
A cold front.
A front is part of a middle latitude low but it is not part of a tropical hurricane. Fronts happen when cold and warm air masses collide or occlude.
Warm air masses are lighter than cold air masses because the molecules of cold air move slower than the warm air's molecules.
Cold fronts occur when masses of cold air with varying temperatures collide. When this occurs, it results in the warm air rising and being replaced with the cold air.
