At a frontal boundary warm, moist air can be lifted upwards, where the water vapor in it cools, and condenses producing clouds, rain, and sometimes thunderstorms.
When these thunderstorms interact with another condition called wind shear, they can start rotating. In some of these storms that rotation can develop into tornadoes.

How does high pressure affect tornadoes?
High pressure tends to supress thunderstorms, making tornadoes unlikely to occur.
What part of a tornado has the fastest winds?
It depends on the tornado. For most tornadoes the fastest winds occur at the edge of the core. For other tornadoes, especially large and/or strong ones the strongest winds occur in the suction vorticies, which are like mini tornadoes moving within the main circulation of a tornado. Tornadoes with this feature are called multiple vortex or multivortex tornadoes.
How are tornadoes and lightning alike?
Both tornadoes and lightning are potentially deadly phenomena that occur during thunderstorms. Aside from that they are two completely different things.
Does lightning strike in a tornado?
Since tornadoes occur during thunderstorms they are usually accompanied by lightning, but it does not necessarily occur inside the tornado.
What is the function of barometer?
The function of a barometer is to measure atmospheric pressure. This reading aids in making short-term weather predictions like high-pressure ridges and frontal boundaries.
What occur at frontal boundaries?
Clouds and precipitation
Why do tornadoes occur in florida?
Florida has a very warm, moist climate, making it very prone to thunderstorms. When the storms that form along frontal boundaries (which tend to be stronger) encounter wind shear they start rotating, which allows them to produce tornadoes.
What frontal boundary do hurricanes form at?
Hurricanes do not form along frontal boundaries.
Do tornadoes form at the boundaries?
Very often they do. Tornadoes typically form along from thunderstorms that occur along or near a cold front (where cold air pushes into warm air) or dry line (where dry air pushes into moist air). However tornadoes can also form in the absence of boundaries such as in the outer rain bands of a hurricane.
When do most tornadoes occur?
Most tornadoes occur in spring.
What is the percentage of thunderstorms do tornadoes occur?
Tornadoes occur in about 1% of thunderstorms.
In what weather do tornadoes occur?
Tornadoes occur during severe thunderstorms.
Is there a tornado season in Houston?
Unlike north central Texas, Houston is not in Tornado Alley. Smaller tornadoes can occur during severe weather. They are most likely to be found along frontal boundaries of an air massduring the spring months. Tornadoes in Houston usually measure a weak F1 on the old Fujita scale, and cause light to moderate damage to well-constructed buildings. The strongest recorded tornado in Houston history was an F4 on November 21, 1992, part of a large outbreak of tornadoes.
Can tornadoes occur in Hawaii?
Yes, tornadoes can occur in Hawaii, but they are very rare.
Do tornadoes occur in Beverly Hills?
Yes. Tornadoes can occur in Beverly Hills.
Can tornadoes occur in the northern hemishpere?
Yes. Tornadoes occur in both hemispheres.
Do tornadoes occur in winter?
Yes. Tornadoes can occur at any time of year.
