A cloud band associated with a cold front is approaching far southern Victoria
and Tasmania.

A trough extends through NSW and into the Tasman Sea. This is producing areas of
middle level cloud with showers through NSW, far eastern Victoria and the Tasman
Sea. Isolated thunderstorms are visible within the cloud, mainly over western
NSW and the Tasman Sea.

Some low cloud is over northeast NSW, southeast Queensland and along parts of
the south coast of Australia due to onshore flow.

Mid-level cloud with embedded thunderstorms is streaming away from the tropics
over the northern Indian Ocean, stretching southeast through central parts of WA
to central Australia. This is brought about by an upper jetstream, bringing
tropical moisture to continental Australia.

The rest of the continent is mostly cloud free under the influence of a high
presure ridge.

About these Images : To assist in interpreting greyscale IR images, methods can be used to colour all pixels representing a particular temperature range. The temperature of clouds is associated with their height, so highlighting certain temperature ranges is useful for estimating the height of the observed clouds. These precision of these temperature measurements are within one or two degrees Celsius. Images coloured in this way are known as 'false colour' images.
