A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast.
If a warm front passes a given point, a cold front must have passed through a day or so earlier. The converse does not hold — cold front passage does not mean you should expect a warm front a day or so later.
This time it was on the backside of an east coast cold front in the middle of January. The visibility had to be 100 miles and check points were lined up out front like fence posts. A real no-brainer cross country.
This situation is seen with rapidly moving cold fronts lifting warm moist air to above the freezing level. The air condensates and rain can fall.

Occur when an air mass is trapped between two colder air masses and is forced to higher altitudes. Occluded fronts may combine characteristics of both warm and cold fronts.
