Try this:
Height of cloud tops relative to the aircraft=
Range in feet x (weather radar scanner tilt - 1/2 beam width)
------------------------------------------------------------
60
e.g a cloud 50 miles away,tilt 1 deg up ,beam width 4 degrees:
50x6080x (1-2)
-------------- = 5067 ft
60
Hope it helps, but gotta agree with smudger..give them plenty of space
