How can it rain while the temperature and humidity support snow?

It rains because the upper atmosphere is warmer than the air at the ground. Generally this is freezing rain, but not always.

It depends on what you mean by "does it get warm?". See below.\n\nIt 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.\n \nWhen 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 C or 32 F) 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.\n\nHowever, 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 ground temperature is 5 C (41 F).

It depends on how wet the snow is. The US Geological Survey says a rule of thumb is 10 inches of snow equal an inch of rain. But wet heavy snow my be 4-5 inches  and light fluffy powder may be more than 10 inches.

When people talk about what temperature it is, they are talking about the temperature at near ground level. However, this temperature is not the key to creating snow. Snow is typically formed much higher in the atmosphere from typically at 1000+ ft up in the air. So when ever you have moisture laden air cooled to below 32°F (0°C for your EU friends), snow will form and fall to the ground. If the temperature near the ground is below 32°F (30, 20, 10, etc), the snow will land. If the temperature is above 32°F, it may melt on the way down and show up as rain.\n\nNow there may be geographical and weather pattern reasons why it doesn't snow very often when it is below 32°F in France, but scientifically there is no reason it can not.

Powder is great, and it´s bad when there´s ice! But it´s also good, when the snow is almost melting. But then yah should not fall...

You mean the dew point, right? That is the temperature at which the air will become saturated with water and dew will begin to form as the air cools. As air cools below the dew point you can get fog, frost, clouds, rain, or snow.

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.

Actually, it wouldn't.  There will always be a vapor as long as there is a sunlight OR temperature above 32F/0C.  Even of the rain that falls, much of it goes back into the air (notice a heavy humid feeling during and immediately after a rain?).  When it sleets or snows, as soon as the sun comes out the light works by being focused by the crystal structure of the ice and literally vaporizes the ice, going straight to vapor, skipping (for the most part) the water phase.  Water likes a balance.  When water is scarse in the air, water molecules on the surface fairly leap into the air, unless the air is crowded with them already.  Fascinating cycle.

Pressure changes affect the wind.  Temperature change determines whether it will rain or snow.

Depends on where you live.  In the polar regions, it snows alla time, it never rains.

It rains when the air can no longer hold onto the moisture in an evaporated, cloud form.  It can be cold and rainy, mild and rainy, or hot, muggy and rainy.  \n\nMoisture moves on the air currents. During winter, rain usually comes when it is cold because the air currents bring COLD air from the far north (remember the "jet stream" they talk about on the news?)  But when air currents from the tropics move overhead, temperatures are warmer because it isn't cold in the tropics. And tropical air often brings a huge amount of rain (think hurricanes).\n\nDuring summer, if there is moisture in the air, a lot of moisture, it condenses and turns into liquid form (rain) when temperatures and moisture content of the clouds reaches the right combination.

As the water vapor cools along with the air, it begins to go into a liquid state and will collect on anything it can, usually dust particles in the air. From there, it depends on the amount of water and the air temperature whether you will get dew, rain or snow.

Snow is frozen/crystalized rain.  When the rain drop leaves the cloud, it will freeze as it descends to earth.  This frozen rain drop is what we call snow.

"There are basically four elements of weather that can help describe weather. The four elements include  wind, temperature, air pressure and moisture." (From the ref.) These may seem an arbitrary choice until you realize that they are all easily measurable and independent of each other, whereas dew point and cloud cover can be said to derive from humidity, temperature and pressure.

It depends on a number of variables. One factor is the temperature difference between two air masses. The warm air will hold more water than cold air, so if a warm front hits a very cold air mass the cold air will cool the warm air and it will become oversaturated with water vapor. The more the warm air is cooled the more rain will fall. \n\nAnother factor is the way the air masses are moving. If a warm front moves over cold air slowly it will form a gradual transition with the cold air remaining near the ground and the warm air climbing gradually over it. This will produce a prolonged period of rain. If a cold front pushes under a warm air mass it may form a much steeper boundary area between the two air masses. This can produce very hard short periods of rain. \n\nHere's a little diagram:\nhttp://www.tiscali.co.uk/reference/encyclopaedia/hutchinson/m0006324.html

The warm air pushes over the denser cold air and itself cools  - hence the snow. As the cold air gets replaced by the warmer air, we experience  the rain.
