I think the possible severe part is strong winds and the dangers of fire starting from lightning strikes. Very dry.
The problem with storms, although in the forecast there is a possibility of 25% chance of receiving 1mm, BoM states that there is a unpredictable factor to a certain degree to accurately forecast that total, we could receive higher amounts very quickly than what the models suggest. (Mainly for storms)

But in this case I think the wind and fire risk is the main concern. There is moisture and it would support good size hail but is there enough moisture for that to happen in this case? Large hail that is.

Hopefully Ken maybe able to a paint a clearer picture in regards to hail with this one, or even clarify what could be the severe sector of the storms.

Cheers
