Large storm systems push that cold air southward and the leading edge of that cold air is the front.
Cold fronts
are notoriously known for their bad weather such as thunderstorms, tornadoes and heavy rain. Many of our severe weather events during the winter months are caused by cold fronts.
What weather do thunderstorms form in?
Thunderstorms form when
warm, moist air rises into cold air
. The warm air becomes cooler, which causes moisture, called water vapor, to form small water droplets – a process called condensation. The cooled air drops lower in the atmosphere, warms and rises again.
What type of front creates most thunderstorms?
Cold fronts
often come with thunderstorms or other types of extreme weather. They usually move from west to east. Cold fronts move faster than warm fronts because cold air is denser, meaning there are more molecules of material in cold air than in warm air.
What are the 4 types of thunderstorms?
- The Single-Cell.
- The Multi-Cell.
- The Squall Line.
- The Supercell.
What time of day do thunderstorms most often form?
when are thunderstorms most likely? Thunderstorms are most likely to happen in the spring and summer months and during
the afternoon and evening hours
but can occur year-round and at all hours. southeastern and western states, most thunderstorms occur during the afternoon.
What type of front causes very little weather changes?
Warm fronts
often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth’s surface.
What type of front has rain showers and thunderstorms?
A
warm front
will steadily rise _________the cooler air and create gentle rain showers. An Occluded Front is formed when a ________front catches and overtakes a warm front. A mix of rain and thunderstorms can occur as a result. A Stationary Front is the boundary between _______air masses that are not moving.
Which frontal boundary will all day rain occur?
| Question Answer | Along which frontal boundary will all-day rain occur? Warm front | What happens at a Stationary Front? Warm and cool air collide making huge clouds and rain, snow or fog. | What happens to winds in the northern hemisphere as a result of the Coriolis Effect? Deflected to the right |

What are the 2 types of thunderstorms?
There are two main types of thunderstorms:
ordinary and severe
. Ordinary thunderstorms are the common summer storm. Ordinary thunderstorms last about one hour. The precipitation associated with them is rain and occasionally small hail.
What’s the difference between a strong and heavy thunderstorm?
Strong:
Winds will either be between 30-57 MPH
and hail will usually be pea size, dime size, or nickel size. Sometimes though the storm will only be categorized as strong ONLY because of hail or just strong winds. Severe: Storms will have winds 58 MPH or above and hail will be either quarter size or above as well.
How long do thunderstorms usually last?
Thunderstorms typically do not last very long and will most often pass by your location
in less than one hour
. The best defense against thunderstorms is to stay inside a sturdy, substantial building that can protect you from lightning, hail, damaging wind, heavy rain, and tornadoes.

Don’t stand near a window to watch the lightning
.
What causes weather fronts?
The answer is “
moisture and differences in air pressure
.” A front represents a boundary between two different air masses, such as warm and cold air. If cold air is advancing into warm air, a cold front is present. On the other hand, if a cold air mass is retreating and warm air is advancing, a warm front exists.
What kind of front causes rain?
As the warm air is pushed higher, the moisture it carries condenses and falls as rain. This is why a lot of heavy rain is produced along
a cold front
but once the cold air mass has come in this often abruptly changes to a clear spell of weather.
