Velocity of Raindrops

Question: What is the average height that raindrops form?  Do they fall at 
terminal velocity?  If they do not fall at a terminal velocity, why not?  The 
raindrop forms a shape that has the least resistance as it falls, does not it?  
Or, does it fall fast but have little momentum?
---------------------------------------
Raindrops do fall at terminal velocity or even faster if they are 
pushed by a downdraft.  But terminal velocity for even a large drop is not 
very high because the drop flattens out into sort of a pancake shape, so it 
actually has more air resistance than a sphere.
