speed an average snowflake fall
In a typical winter storm, snowflakes begin their descent from a cloud layer about ten thousand feet above the ground. Assuming an average fall speed of 3.5 feet per second, a snowflake would take more than 45 minutes to reach Earth.ear Ron, Snow expert and Colorado assistant state climatologist Nolan Doesken states the vast majority of snowflakes fall at speeds between 1 to 6 feet per second. A snowflake's surface area and its mass are the most important factors in determining the rate of fall.
