Cold Front Weather
•The type of precipitation that will occur along a cold front depends on the characteristics of the warm air ahead of the front.
•If the warm air is moist and conditionally unstable, thunderstorms can be triggered ahead of the cold front; the thunderstorms will form in a line called squall line; if supercell thunderstorms form, tornadoes, hail, damaging wind can occur.
•If the warm air is stable, the clouds that
form by lifting only
produce light rain.
•If the warm air is dry and stable, no clouds will form at all.
