Meteorological Factors Contributing to July Snowfall: July Snowfall Philadelphia Airport
July snowfall at Philadelphia Airport is an extremely rare occurrence that requires a unique set of meteorological conditions to align. These conditions include the presence of a cold front, an upper-level trough, and sufficient moisture availability.
A cold front is a boundary between two air masses of different temperatures. When a cold front passes through an area, it can bring with it cold air and precipitation. An upper-level trough is a region of low pressure in the upper atmosphere that can cause the air to rise and cool, leading to cloud formation and precipitation.
Moisture Availability
In order for snowfall to occur, there must be sufficient moisture available in the atmosphere. This moisture can come from a variety of sources, such as evaporation from the ocean or from melting snow and ice. If there is not enough moisture available, the precipitation will fall as rain or sleet instead of snow.
