If it is snowing in Great Neck, what type of air mass must be present?

To determine the type of air mass needed for snowfall in Great Neck, we need to consider the characteristics of air masses and the conditions required for snow formation.

An air mass is a large body of air that has relatively uniform temperature and moisture content over a given area. The type of air mass present depends on its source region, which could be over land (continental) or over water (maritime). Additionally, air masses can be classified based on temperature characteristics: warm or cold, and moisture content: dry or moist.

For snowfall in Great Neck, we generally need a cold and moist air mass. Snow forms when the temperature in the atmosphere is below freezing (0°C or 32°F) and there is sufficient moisture present.

To determine what type of air mass is present, you need to examine the weather conditions leading up to the snowfall. If the air mass originated from a colder region and has picked up moisture along its path, it could be a cold and moist air mass responsible for the snowfall.

Keep in mind that local weather conditions can also be influenced by other factors, such as topography, prevailing wind patterns, and the presence of weather systems like low-pressure systems or frontal boundaries. Observing weather reports, satellite imagery, and consulting with meteorological sources can provide more specific information about the air mass present and the potential for snowfall in Great Neck.
