Supercells possible Qld and N NSW Oct 12 to Oct 16 2011

Published by:

Given the moisture building up under a trough in SE Qld and contracting inland, and given the wind profile, a combination of shear and instability is sufficient for supercells and large hail with damaging winds. Initially the main focus will be in the Mackay to Rockhampton region but generally the region in the Central Highlands near  Emeral etc will see an increase in thudnerstorm activity and severe storms included.

Severe storms hail and winds 28th September 2011

Published by:

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:

You can see at the end of the period of the Yarrwonga radar an impressive line with bow echo behaviour.
