If the weather ahead of the cold front was overcast, the temperature change with the front was slight, and the air behind the front was clear, the increased solar heating behind the front could more than offset the cooler air mass. The daytime temperatures might be warmer behind the front, but the nights would be colder.

    First off this was likely a very weak front. But in any case, more solar radiation reaching the surface, due to clearing skies and depending on your location, compressional heating could definitely play the largest role. Winds behind a cold front are normally west/ north westerly in north America. If you live on the lee side of mountains or large hills west winds moving down slope will sink and compress. This is quite common in regions just east of the Rockies. Air heats through the process of compression–laws of thermodynamics. Sometimes this process may significantly raise temperatures in these regions.
