As a meteorologist with a deep understanding of the atmospheric conditions that lead to various weather phenomena, I can provide a comprehensive explanation of the relationship between humidity and snowfall.
Humidity is a measure of the amount of water vapor in the air. It is typically expressed as a percentage, with higher percentages indicating more water vapor present. There are several types of humidity, including relative humidity, which is the ratio of the current amount of water vapor in the air to the maximum amount the air could hold at that temperature. When the air is saturated with water vapor, the relative humidity is 100%.
Now, let's discuss the conditions under which snow can form. Snow is a form of precipitation that occurs when atmospheric water vapor freezes into ice crystals. This process is known as deposition. For snow to form, the temperature must be at or below the freezing point (32°F or 0°C) throughout the entire depth of the cloud from which the snow is falling. This is because if the temperature is above freezing, the ice crystals will melt and turn into rain before reaching the ground.
However, the presence of high humidity does not necessarily prevent snow from forming. In fact, high humidity can actually contribute to the formation of snow. This is because when there is more water vapor in the atmosphere, there is more raw material available for the formation of snow. As the air rises and cools, it can hold less water vapor, leading to the condensation and deposition processes that form snowflakes. If the relative humidity is high, there is a greater likelihood that the air will be saturated and conducive to snow formation.
The statement that "If the humidity level is low enough, you can actually get snow even when the dry bulb temperature is several degrees above freezing" is not entirely accurate. While it is true that snow can form under a wider range of temperatures than just at or below freezing, it is not correct to say that low humidity alone can cause snow to form when the temperature is above freezing. The temperature must still be low enough for the water vapor to freeze into ice crystals. However, low humidity may mean that there is less water vapor available to form precipitation, which could result in lighter or less frequent snowfall.
In summary, humidity plays a complex role in the formation of snow. High humidity can provide the necessary water vapor for snow formation, while low humidity may limit the amount of snow that can form. However, the temperature must still be at or below freezing for snow to form, regardless of the humidity level. Understanding these atmospheric conditions is crucial for predicting and understanding weather patterns and the occurrence of various types of precipitation, including snow.

When there is more water vapor in the atmosphere, water or snow can't evaporate as much because the air is already saturated with water to a high degree. ... If the humidity level is low enough, you can actually get snow even when the dry bulb temperature is several degrees above freezing.
