It's not quite that simple. Snow that falls when the temperature is near the freezing point has a much higher water content per inch (wet, heavy snow) than the fluffy snow that falls when it is much colder.\n\nAccording to wilipedia, 8" of average snow equals one inch of rain, but the variation is very great. Hard packed snow that has been on the ground for a long time may be as much as 50% water, while newly fallen snow that falls at low temperatures can be more than 90% air.

Depends on pressure/altitude.  At sea level its about 100C or 212F.

The probability of snowfall varies with season, location, and other geographic factors such as latitude and elevation. In the latitudinal area closer to the equator, there is a rather small chance of snowfall, 35° N and 40°S are often quoted as a rough delimiter. The western coasts of the major continents remain devoid of snow to much higher latitudes.\n\nPermanent snow covering is affected by factors such as the degree of slope on the land, amount of snowfall and the force and nature of the winds. As temperature decreases with altitude, high mountains, even near the Equator, have permanent snow cover on their upper portions, around 5300 m high. Examples include Mount Kilimanjaro in Tanzania and the Tropical Andes in South America; however, the only snow actually to appear on the Equator is at 4690 m altitude of the southern slope of Volcán Cayambe in Ecuador (Google Earth images). Conversely, many regions of the Arctic and Antarctic receive very little precipitation and therefore experience little snowfall despite the bitter cold (below a certain temperature, air essentially loses its ability to retain water vapor). Here, the snow does not melt at sea level.

Sleet freezes on the way down. Freezing rain freezes after it hits the ground, the ground must be below freezing. Sleet will not stick, but it will accumulate like snow.

No.  The cloud will form when the ambient temperature inside the cloud is lower than the dew point.  The moisture may actually form snow (on a summer day!) which melts on the way down to form rain.  The temperature outside the cloud may be less relevant because clouds often form when a column of moisture-laden air rises locally condensing into a  cloud right above the column.

could be snow, could be +10 or +20 degrees, could be a little bit of rain.  One never knows in the spring time!

go to weather.com a type in ur city or town.\n                      OR\nlook at a weather chart\n                      OR\nGo outside and measure the snow with a ruler.

That is a fantastic question.\nIt is a matter of humidity. The cold weather\nthat allows snow means the air is not humid\nenough to allow an electric current to travel\n(along the water vapor in the air) over the differently\ncharged clouds and sky. People who say temp are\nsort of right, but it is the low temp that leads to the low\nhumidity that causes the "problem".\n\nThanks for asking such a good question.

About -1.8 degrees C, due to the freezing point depression of the dissolved salt (that's why they salt roads in winter)

Snow forms when there is cold air (below freezing) and percipitation falls.  Snow is made out of ice crystals.  Sleet occurs when rain falls from warm air (above freezing) and passes through cold air (below freezing) on the way down, and freezes into ice pellets. (Note: If the air is warm (above freezing) and the objects on the ground are cold, the rain falls, then freezes onto the objects on the ground.  This is called freezing rain.)

A huge factor in snowmaking is not only temperature but humidity. I believe some of the more advanced snowmaking systems can get around this but at my resort I know that freezing temperatures alone are not enough to make snow. Our systems requires that the humidity to be very low or we can't get the water to freeze.

Sleet is a mix of water and snow.  Freezing rain is more interesting.  Usually water freezes at 0 degrees Celsius.  But if it's completely free of bubbles and dust particles that ice crystals can start to form on, like in the upper atmosphere, it can cool down to minus 40 Celsius before it freezes.   This is supercooled water.  The moment supercooled water hits a solid object, like the ground or an aeroplane wing, it freezes.  Freezing rain is supercooled water, and it's very dangerous to aircraft.

Your temprature of 36 degrees is simply a ground level temprature.  It is not the air temprature of the weather system that you are currently within.  Because of that, the air temprature above you, where the snoe will form is quite a bit colder.  Once snow starts to form within the weather system, the ground temprature will begin to drop from 36 Degrees to around 30-28 degrees for a short period of time.  From 22-28 degrees snow falls best.  THe sudden drop in temprature isn't that hard to predict, so chances are your weather station was indeed correct.
