MIKE MOSS SAYS: John, The arrows on the iControl display are keyed to cell or precipitation area motion, with the arrow indicating the extrapolated direction of motion and the "min" figures indicating approximately how far the cell will have moved after the labeled number of minutes. So, "min" in this context is an abreviation for "minutes."
It's worth stressing that precipitation areas are highly subject to rapid development and dissipation, to notable acceleration or slowing of forward movement, and occasionally to directional changes, so you should treat the arrows and timing arcs as pretty rough approximations in general.
