Keeping this in view, how cold does it have to be for snow to stick to the ground?
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.
Secondly, can it snow at 34 degrees? By far the easiest is to just have freezing temperatures in place when moisture arrives. If it"s around 34 degrees or colder when the moisture arrives, it"ll snow (Yes, it can be a couple of degrees above freezing and snow).
In this way, what makes snow stick to the ground?
When the temperature is slightly warmer than 0°C, the snowflakes will melt around the edges and stick together to become big, heavy flakes. This creates 'wet' snow which sticks together easily and is good for making snow men. If the temperature is at freezing point or below, the snow will stick.
Will snow stick if the ground is wet?
When the temperature gets lower, the rain is cooling as it falls, but it's hot enough to remain water. Since the amount of water on the area of ground is lesser than the snow on top of it, the final state of the system is when the wet ground has "dried", so that the snow sticks to the ground.
