I was watching a big band of showers coming across northern Vic yesterday
afternoon, looked most promising unless one looked outside at the 500m
visibility dust storm - all we got was about 1 minute of mud. The
Yarrawonga radar was quite fooled by the dust.

From the "Interpreting Weather Radar Images" page
(http://mirror.bom.gov.au/weather/radar/radarexp.shtml):
"3. The radar may sometimes detect faint echoes from non-precipitation
targets such as aircraft, large fires, swarms of insects, flocks of birds
or even the surface (when unusual atmospheric conditions bend the radar
beam back down to the surface!)."
This was very apparent during the worst of the Canberra bushfires.
The weather radar showed what looked like possible thunderstorms or
rain with the weather change, but it was just the plumes of smoke,
leaves, twigs etc. - not a drop of rain.
