How many degrees does it have to be to snow, right now its 29, how much lower to snow????

Answer 1

There is no specific temperature the atmosphere has to be to create snow. There is a range that the surface temperature typically is for snow that begins to stay on the ground (about 30-40 degrees depending on the temperature profile of the atmosphere). The important thing regarding snow is that at some point in its descent it must freeze and remain frozen until it hits the ground. 29 degrees is plenty cold enough to snow as long as that layer of cold is deep enough.

Answer 2

When is it too warm to snow? How does snow form if the ground temperature is above freezing?

Snow forms when the atmospheric temperature is at or below freezing (0 Celsius or 32 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.

However, the snow can still reach the ground when the ground temperature is above freezing if the conditions are just right. In this case, snowflakes will begin to melt as they reach this warmer temperature layer; the melting creates evaporative cooling which cools the air immediately around the snow flake.This cooling retards melting. As a general rule, though, snow will not form if the groud temperature is 5 degrees Celsius (41 deg Fahrenheit).

Why can snow fall when temperatures are above freezing?

Snow forms in the atmosphere, not at the surface. So snow can fall when surface temperatures are above freezing as long as atmospheric temperatures are below freezing and the air contains a minimum moisture level (the exact level varies according to temperature).

Is it ever too cold to snow?

No, it can snow even at incredibly cold temperatures as long as there is some source of moisture and some way to lift or cool the air. It is true, however, that most heavy snowfalls occur with relatively warm air temperatures near the ground - typically 15°F or warmer since air can hold more water vapor at warmer temperatures.

Answer 3

Wetbulb is a term to pay attention to. Basically if there is high humidity, the air temp needs to be lower. If the humidity is very low, then the air temp can be higher than 32. Ive seen it snowing at 42 degrees before, it wasnt sticking, but it was still snowing. The only bad thing is that in conditions where the air temp is below freezing and it's still raining, you get an ice storm.

Answer 4

It only has to be 32 for snow to stick, and that's if the ground's not wet already. It can snow at 35 or so, but it will melt before it hits the ground. It's the temperature of the atmosphere and how much moisture is there that will determine if it snows and how much. Where are you at anyways? It's like 80 here!!

Answer 5

It could snow at 29, doesn't mean it will. It was 15 here last night and didn't snow. Last year it snowed her at 35 -melted as soon as it hit the ground but it still snowed.

Answer 6

Technically it only has to be 32 degrees F to snow. And 29 is ground temperature, its much colder where the clouds are.

Answer 7

Although there are a number of factors that determine how precipitation falls, the barometric pressure, and temperature are the biggest. 32 F at sea level is sufficient for snow. A higher elevation will bring snow at a higher temperature.

Answer 8

It can snow even if it is above freezing. Just like rain I think it has to do with moisture in the clouds.

Answer 9

0 degrees with humidity to snow.

Answer 10

That temperture is perfect for snow, all u need is a high humidity and moisture
