The ground stores energy from solar radiation, and can have a "memory" of more than a week. If the ground is above freezing, it will be difficult for snow to accumulate.
It freezes in ground temperature and is very dangerous
The temperature in the clouds must be below freezing. If it is below freezing (32 Fahrenheit, 0 Celsius) all the way to the ground, snow will fall. If not, it will melt and reach the ground as rain, freezing rain, or sleet, depending on if it has time to refreeze. Snow can even fall if the temperature at the surface is a little above freezing if it doesn't have time to melt as it falls.
Raindrops which pass through a layer of freezing air near the ground become sleet.
Freezing rain and a slick ground
Freezing rain occurs when the layer of freezing air is so thin that the raindrops do not have enough time to freeze before reaching the ground. ... Sleet is simply frozen raindrops and occurs when the layer of freezing air along the surface is thicker. This causes the raindrops to freeze before reaching the ground.

Sleet forms when it hits the ground

This is because there is a temperature inversion at the surface, which can occur for several reasons. This means that the air above the surface is actually warmer, and in this case above freezing, than the air right on the ground. This causes snow from higher in the atmosphere to melt into raindrops, but the rain doesn't have enough time to refreeze into ice pellets (Sleet) before reaching the ground, so you get rain. This is called freezing rain though, since those sub-freezing temperatures on the ground cause the rain to freeze on contact. This creates a sheet of ice, or glaze, covering everything.

The raindrops become supercooled while passing through a sub-freezing layer of air many hundreds of feet above the earth, and then freeze upon impact with any surface they encounter.[1]Thus resulting ice cubes
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!
Sleet is formed when ice crystals fall as rain that freeze before it hits the ground. Hailstones form when strong winds blow raindrops back upward to the top of where the temperature is freezing. Then, the raindrops freeze into small pieces of ice. This process might happen several times where many layers of ice may build up. Once the hailstones are too heavy and the wind can blow them back up, the hail falls to the ground.
