Weather aid (5)

I believe the answer is:

radar

(Other definitions for radar that I've seen before include "one sends out signals" , "System that detects and locates distant objects" , "Radio location" , "Early warning system" , "Instrument to detect and locate distant objects" .)

I've seen this clue in the King Feature Syndicate.
