Just discovered this. You can zoom in, show roads and towns etc. It works both night and day.
What i find surprising is those places that seem to generate their own weather in the sense that clouds stay there rather than moving around with the rest of the weather systems. This morning, those places have included Lake Torrens, Balgo Hills and Strathgordon.
The other surprising thing is those places that experience a sudden burst of heavy cloud that dissipates over the next hour or so. This happened at 4 am north of Bicheno in Tasmania.
