The ground temperatures, though, are cold enough that no rain falls, but only snow. Anywhere above 50 degrees, and the ground level temperatures melt the snow into rain before it can be seen. Could it be possible that the snow finally gets converted to rain while coming down to earth? I meant whether snow and rain could simultaneously coexist?
If yes, how? Shaviv, I recall this being in the news from several years ago. It is referenced here at RealClimate, but I cannot find anything on this subject. Can somebody please simplify this explanation? I'm no dumb ass. I just need a quick answer to my question, "Why do snow and ice melt slowly in the spring even when the temperature is well above freezing?
First, they are white. As a consequence they absorb less of the sunlight. Second, snow and not ice has a lot of small air pockets. It is safe to say that snow will stick to the ground when the air temperature is 32 degrees or lower, but other factors such as the state of the ground and intensity of the snowfall come into play when temperatures are in the middle or upper 30s.
When the temperature of water falls to 0 degrees Celsius and below, it begins to change to ice. As it freezes, it releases heat to its surroundings. However, in some ways water is not like other types of matter.
The Timeline of Hypothermia When the water temperature is 40 degrees or below, serious injury can result in as little as a few minutes. Even in water temperatures approaching 50 degrees, death can occur within the first hour of cold water immersion. Humans freeze to death when their internal body temperature drops below 70 degrees. The amount of time you can survive in the cold drops along with the temperature.
Proper hydration maintains good blood flow and other bodily functions — helping you stay warm. It is briefly possible to do it at 50F. Obviously, within minutes, the air temp falls towards 32F, but it was snowing briefly, at 49F! But that is why, especially in daytime…when it is usually warmer than night, we often see snow begin at F, and then temps plummet…because the first snowflakes are melting and cooling the air, at first…so that subsequent snowflakes never melt!
This process happens all the time it rains or snows. The precipitation, of any type, cools the air it falls through, especially in the beginning of an event, when it is used up…saturating that air virga. Community Colorado Living.

Flakes only form at or below 32F, in the cloud But again, how is it possible to be 45F and snowing? You can have a shallow warm layer, too shallow for the flake to melt Remember, ANY moisture falling through air, is affected by the air but is also affecting the air, in return!
If the layer is too shallow, or the snowflakes can evaporate and cool that layer down… So, some moisture is spent, cooling the air.
