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.
What else can I help you with?
How much humidity is need for snow to fall?
It doesn't matter what the humidity is at the surface. You need to be looking up somewhere around 5-10,000 feet and up near the 700mb pressure level. You're probably not forecasting the weather though, so it would suffice to say that the air in the atmospheric column will become saturated as precipitation moves in and sublimates. By the time snow reaches the ground, relative humidity is typically 90%+ at the surface.
Can snow melt at 38 degress?
Snow can start to melt at 38 degrees Fahrenheit, as long as the air temperature remains above freezing. When the temperature rises above freezing, the snow will begin to melt.
Can snow melt if it is 35 degrees F?
Yes, snow can melt at 35 degrees Fahrenheit if the air temperature is warm enough to increase the snow's temperature above freezing. However, the rate at which the snow melts will depend on factors such as humidity and sunlight.
What determines whether precipitation falls a rain or snow?
The temperature of the air near the ground is the main factor in determining whether precipitation falls as rain or snow. If the temperature is above freezing, the precipitation will fall as rain. If the temperature is below freezing, the precipitation will fall as snow.
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?
The mass of a pile of snow can decrease on a sunny day even if the air temperature does not rise above zero degrees Celsius due to sublimation. Sublimation is the process where a substance goes directly from a solid to a gas without passing through the liquid phase. In this case, the sunlight provides the energy needed for the snow to sublimate, causing the mass of the snow pile to decrease.
How low does the temperature have to be snow?
Snow is made from Ice crystals. Thus for snow to form and precipitate, the ambient / air temperature must be below 0 degrees Centigrade.
What forms when air temperature is below freezing and water vapor changes directly to solid?
snow
What names a type of precipitation that forms when the air temperature is below 0 Celsius?
The type of precipitation that forms when the air temperature is below 0 degrees Celsius is called snow.

How cold does it need to be to safely throw hot water into the air and create a snow effect?
To safely create a snow effect by throwing hot water into the air, the temperature needs to be below freezing, typically around 0 degrees Fahrenheit or lower.
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.
Does temperature need air?
No
Can snow melt at 38 degress?
Snow can start to melt at 38 degrees Fahrenheit, as long as the air temperature remains above freezing. When the temperature rises above freezing, the snow will begin to melt.
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.
