At the moment it is very hot and about to get a whole lot worse. But at least all the laundry will be dry in a few minutes tomorrow.
Essentially there is a low-pressure system and trough that will draw hot air from the centre of Australia. The hot air mass has been present for a number of days and it will start to move towards NSW and eastern Australia with moderate to strong winds forcing the change.
The N to NE winds are about to change to the NW, and it's going to be a hot one. So much so I have not even thought about picking up a camera today.
