Definition#

A cold front is the leading edge of a cold air mass that displaces a warmer air mass. The cold, denser air wedges under the warm air, forcing it upward rapidly.

Why It Matters Operationally#

Cold fronts produce narrow but intense bands of weather: thunderstorms, heavy precipitation, turbulence, and significant wind shifts. Passage is typically rapid, with conditions improving quickly behind the front.
