Along fronts low pressure systems form. Depending on what type of front it is, the air pressure will drastically increase or decrease. Because the front is the edge of an incoming air mass, precipitation occurs often ahead of the front. Fronts of incoming air masses are subject to prevailing winds, and are influenced in direction. Often, clouds form along fronts, which is why when a front has passed in there has been rain, or snow, or any other form of precipitation.
Air fronts form along boundaries between two air masses with different temperatures and characteristics: cold fronts occur when a colder, denser air mass displaces a warmer air mass, while warm fronts form when a warmer air mass rises over a colder air mass.
Tornadoes are commonly associated with cold fronts, where a cold air mass collides with a warm air mass. The contrast in temperature and humidity between the two air masses creates instability in the atmosphere, which can lead to the development of severe thunderstorms and tornadoes.
Hurricanes typically form along stationary fronts or tropical waves, which are areas of low pressure near the surface where warm, moist air converges and rises. These fronts provide the necessary conditions for the development of organized thunderstorms that can eventually evolve into a tropical cyclone.
Precipitation typically forms along both warm and cold fronts. Along a warm front, precipitation is usually light and steady, while along a cold front, precipitation is often more intense and short-lived.
Violent storms typically form from cold fronts, where a colder air mass is advancing towards and displacing a warmer air mass. The rapid lifting of warm, moist air along the cold front can lead to the development of thunderstorms and severe weather. Additionally, stationary fronts and occluded fronts can also trigger violent storms under the right atmospheric conditions.
They form along cold fronts.
Tornadoes often, though not always, form along weather fronts, where air masses of differing characteristics collide. The fronts that most commonly produce tornadoes are cold fronts and dry lines.
High pressure is not associated with fronts (or air mass boundaries).
Tornadoes are most often associated with cold fronts, but they also frequently form along dry lines and occasionally along warm fronts. Some tornadoes, such as those spawned by hurricanes, form in the absence of any front.
Thunderstorms and tornadoes most often form along cold fronts but they can form along dry lines and, on rare occasions, warm fronts. Some may form in the absence of any front.
Air fronts form along boundaries between two air masses with different temperatures and characteristics: cold fronts occur when a colder, denser air mass displaces a warmer air mass, while warm fronts form when a warmer air mass rises over a colder air mass.

Condensation and wind shear are both needed for tornadoes to form. Tornadoes can form along stationary fronts as well.
Most often the storms that produce tornadoes an other severe weather form along cold fronts.
A hurracan or a storm.
Thunderstorms are most likely to form along fronts where contrasting air masses meet, such as cold fronts, warm fronts, or stationary fronts. These fronts create the instability needed for thunderstorm development by forcing warm, moist air to rise and cool, leading to the condensation of water vapor and subsequent storm formation.
Isotherms are a form of contour line to match points with the same temperature and observe rapid changes in temperatures. Fronts are the leading edge of an air mass. Fronts occur along isotherms because of the change in surface temperature, but isotherms are not formed, they are a tool used to analyze surface temperatures.
