its either ready for departure holding at taxiway Lima, (adjacent to hte runway)
or it could be ........
information lima is the weather report via the ATIS system.
the reports are released daily, and as each one is released they are updated, so wen the airport opens its alpha and at hte end of the day its usually at quebec for Q or something around that letter.
its just terminology so that ATC know you have noted the current weather, and they dont need to tell you about the weather, because you have already checked and are up to date with Lima
