The air at ground level or the air at the altitude where the snow forms?
Snow forms in clouds and then falls. Therefore it can be and usually is warmer at ground level than in the clouds...Answer...water moisture freezes at 0° C or 32° F so it would have to be freezing in the clouds where the snow forms.

How low does the temperature have to be for snow?
Snow is made from Ice crystals. Thus for snow to form and precipitate, the ambient / air temperature must be below 0 degrees Centigrade.
How can the mass of a pile of snow decrease on a sunny day when the air temperature does not rise above zero degrees celsius?
When the sunlight strikes the snow, the surface of the snow is heated above the air temperature and some melting and evaporation occur.
How does the temperature of the air affect the amount of humidity that you feel How does the air's temperature also influence the form of precipitation that falls?
The higher the temperature of the air the higher the amount of humidity you feel. Also the colder the airs temperature it can cause precipitation such as hail, snow, and sleet rather then just rain.
Does it have to bebelow freezing for it to snow?
Snow forms when the atmospheric temperature is at or below freezing (0 degrees Celsius or 32 degrees Fahrenheit) and there is a minimum amount of moisture in the air. If the ground temperature is at or below freezing, of course the snow will reach the ground. In the clouds, the water droplets freeze and become ice crystals, or snow!
How does snow happen?
We all know that as we go higher in the atmospherethe temperature decreases. Therefore the capability of air to hold the water vapour decreases and excess of water vapour gets collected in the air at a certain height. The air, now having too much water vapour, is said to be supersaturated. Under these conditions, the water vapour condenses on the dust particles present in the air. On further cooling, the water vapour gets converted into snow particles. Crystals of snow are formed by the combination of these particles. When the air cannot bear the weight of the crystals of snow, they fall down as snow flakes and get collected on the mountains.

What forms when air temperature is below freezing and water vapor changes directly to solid?
snow
Is there a temperature where you can't make snow for ski slopes?
for snow to be snow, not water, the temperature of the air has to be below 0 degrees Celsius (freezing point) and the ground has to be below 0 degrees Celsius.
How and why does snow start?
When the temperature is below freezing, moisture in the air will crystalize into snowflakes.
What is snow and how is it produced?
Snow is frozen water vapor. It is produced when water vapor in the air is turned solid by the freezing temperature.
What is the temperature when snow falls when humidity air cools below and what degree?
As snow falls it will evaporate if the surrounding air is drier, and the energy required to turn water or ice into a gas is taken from that air and the air cools. Eventually it cools to saturation, where the temperature and dew point are equal or very nearly so. This temperature - where the dew point and temperature "meet" if you increase the relative humidity to saturation - is the wet bulb temperature.

Does temperature need air?
No
When it rains it is called?
Depends on the air temperature, it could turn to sleet, snow or hail.
