Hi Luke,

I suspected this was a radar artifact (would birds fly directly at the 
radar - and
into an approaching storm?), so asked about it on the Weatherzone forums;
here's what "zathras" had to say about the Melbourne radar loop:

/The weatherchaser link has serious issues, but from your description is 
sounds
like a////feature we have noticed at times.//
//
//It is most probably a reflection from the CBD buildings looking back 
behind the
radar site,////picking up a strong cell 180 degrees opposed to the nominal
observation direction.//
//Check the ranges of cells out west plus the range to the city.//
//The doppler velocity would likewise look displaced./

I hope that helps.
