An onshore wind looks to bring partly or mostly cloudy conditions to much of coastal NSW, including Sydney.
One or two of these showers reach inland as far as Canberra - although rain looks reasonably unlikely for the nation's capital.
"With Christmas still a week away, the forecast is subject to change," senior meteorologist Angus Hines said.
"However Australia can start preparing for the festive season with the likely weather in mind."
The volatile summer conditions are caused by a high pressure system that is strengthening and a trough off the north coast that is eroding, directing hot northerly winds into the state.
A second trough, currently over southwestern NSW, will move through southern and western areas during Tuesday, December 19, before stalling over the northeast mid-week.
This trough is forecast to trigger widespread showers and thunderstorms for Christmas
