An upper trough with particularly cold air aloft produced some impressive and abundant storms across western and Central Victoria and southern NSW. Hailstorms and a few supercells that become outflow dominant dumped hail up to gold ball size mainly across districts in NW Victoria. Main damage reported was from winds although Melbourne Airport cancelled some flights due to lightning and severe weather.
Here are the Yarrawonga and Mildura radars:
