Radar question

jimgub

Hi there! Just a question about some strange patterns appearing on the radar images this afternoon over vic/south eastern Australia.

I'm sure there's a simple explanation but I'm a little baffled unless its just a glitch in the radar imaging. They look like strange arcs that only appear for 1 or 2 images. If you look at the radar over Victoria for the last 6 hrs today on the 1st of april you'll see what i mean.

Thanks!
Jim
