Definition#
A warm front is the leading edge of a warm air mass advancing over a colder, retreating air mass. The warm air rides up over the cold air, creating a gentle slope of clouds and precipitation.
Why It Matters Operationally#
Warm fronts produce extensive areas of low ceilings, reduced visibility, steady rain or drizzle, and icing conditions. They affect IFR operations over a wide geographic area and can persist for many hours.
