What's the Perfect Temp for 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, the snow will reach the ground.

How can it snow at 37 degrees?

For example: If the air temperature is 37 degrees, but really dry, say with a dew point of 18 degrees, then the wet bulb temperature is actually below freezing at 31 degrees, and snow can now be created.

How can it snow at 40 degrees?

when it is usually warmer than night, we often see snow begin at 40-45F, and then temps plummet… because the first snowflakes are melting and cooling the air, at first…so that subsequent snowflakes never melt! This process happens all the time it rains or snows.
