The falling snow does begin to melt as soon as the temperature rises above freezing, but as the melting process begins, the air around the snowflake is cooled. If the temperature is warmer than 2 Â°C then the snowflake will melt and fall as sleet rather than snow, and if it's warmer still, it will be rain.
