Nice, normal, fluffy snow is best formed at +3°C at ground level.
When you get into minus figures the snow becomes more crystalline and powdery but, snow will fall at any temperature below zero.

Snow normally falls between +4C and as low as -15C. Outside these temperatures it is either to warm (rains) or to cold for precipitation to occur.
Snow can occur in freak conditions even when the air temperature is generally well above 4C but these are abnormal events. A few years ago it snowed in SE England on a warm summers day due to a freak weather pattern, needless to say it didn't last long.
Once there is enough snow laying on cold ground (around zero degrees) it can survive well into positive temperatures. I have been on a ski slope with several metres of snow when the air temperature is significantly above freezing (warm enough for just a jumper). As long as it doesn't rain snowfields can survive a prolonged warm spell reasonably well.
Water is unique in that all 3 phases, solid liquid and gas, exist can exist together over a wide temperature range. That is why you can have ice in your drink on a humid day and it doesn't instantly melt.

The best temperature for snow is between 26-28 degrees farenheit, or around -2 celcius. But the upper atmosphere has to be colder than that or else you just get freezing rain and sleet.

If your in the northeast, a storm will be headed to your area around Tuesday. Snow is expected to fall anywhere from 1-25 inches of snow depending on where you are. Definatly, if your in Virginia and Washington DC, you will be getting the 20-25 inches. The more north u go, the less will fall, just because where the storm is coming from. The temperatures are expected to hover in the mid 20's all around the northeast on Tuesday

Snow falls at any temperature below 0 degrees. 0 is the freezing point of all water.

Under 32 F degrees

Around 32 degrees. It all depends on the temperature in the upper and lower atmosphere.

for snow to form it needs to be below freezing. (up in teh air where it forms.
for snow to survive, it will need to be subzero at ground level aswell. otherwise the snow will melt.
