Well it looks like Hobart will be the best city for viewing tonight.
Adelaide and Brisbane are expected to also have good weather but these cities have a chance of the forecast ending up cloudy or even overcast.
Other cities are expected to have cloud however some of them have a chance of skies actually becoming clear.
See the map below.
