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.
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.
Tornadoes generally form along fronts. Whether or not the area is coastal has no significant impact on occurrence.
Tornadoes can occur in the warm sector of a developing mid-latitude cyclone, typically associated with the cold front. Tornadoes often form along the leading edge of the cold front where warm, moist air is lifted rapidly by the advancing cold air.
Tornadoes are not a direct product of fronts but rather of thunderstorms. The storms that produce tornadoes most commonly occur along a cold front or dry line, but can be associated with stationary fronts or, less often, warm fronts. Some tornadic storms develop in the absence of any fronts.
A cold front occurs when a mass of relatively cool or cold air plows into a mass of warmer air. The warmer hair gets force upwards because it is less dense. As it rises it expands and cools and the moisture in it condenses, producing rain and thunderstorms.Sometimes these storms are strong enough to produce hail and tornadoes
They form along cold fronts.

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.
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.
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.
cold fronts
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.
